Norton 360 Antivirus Review

Norton offers the best antivirus protection on all operating systems.


Norton is one of the few brands with a 100% malware protection score. Its real-time malware protection tool, called SONAR, is the best.

To get to this score, we averaged the last 10 test scores by AV-Test, an independent test lab. We also ran our own tests, during which Norton was able to detect malware attacks and phishing attempts in real-time.

Norton SONAR applies heuristic analysis and machine learning to spot known and unknown security risks. This means it identifies new threats through suspicious behavior rather than malicious computer code.


Norton’s Smart Firewall checks incoming and outgoing connections for suspicious behavior. It stops any attack before it becomes a problem.

By contrast, Windows’ firewall only checks incoming connections. It does not monitor whether the software on your computer makes suspicious outgoing connections to other devices.

And that’s not all. Norton’s firewall also cloaks inactive ports, so hackers can’t find them through hacking techniques like port scanning.


Norton’s unlimited VPN (Virtual Private Network) is outstanding. It is fast, secure (AES-256 & OpenVPN), private (no logs), allows torrenting (P2P), and features auto-connect, a kill switch, ad tracker blocking, and a split tunnel.

Most VPN services, like those by Bitdefender, have a daily data limit of 200 MB. To remove the data limit, you’ll have to pay extra. Norton, however, includes its unlimited VPN for free.

Password Manager

Norton’s password manager is excellent. Creating passwords is easy. Auto-filling them is accurate. And you can access your password vault using biometrics scanners (fingerprint or facial recognition).

Prices & Packages

  • Norton Antivirus Plus costs € 15 (Europe) or $ 20 (USA). It offers antivirus, a firewall, and a password manager. It protects 1 PC or Mac.
  • Norton 360 Standard costs € 30 (Europe) or $ 40 (USA). It adds a VPN and dark web monitoring. It protects 1 (Europe) or 3 (USA) devices.
  • Norton 360 Deluxe costs € 35 (Europe) or $ 50 (USA). It adds a privacy monitor and parental controls. It protects 5 devices.
  • Norton 360 Advanced costs € 40 in Europe and is not sold in the USA. It adds identity theft protection and protects 10 devices.
  • Norton 360 Select + LifeLock costs $ 99 in the USA and is not sold in Europe. It adds LifeLock identity theft protection and protects 10 devices.

In some countries, Norton 360 Advanced is called Norton 360 Premium. This is essentially the same product, without identity theft protection.

Bonus Features

  • Web protection: Block malicious websites via the Safe Web extension.
  • Cloud backup: Back up important files in secure cloud storage.
  • Parental controls: Monitor and protect your kids online.
  • Privacy monitor: Scan data brokers for your personal information.
  • Webcam protection: Prevent unauthorized access to your webcam.
  • Dark web monitoring: Scan the dark web for your personal information.
  • LifeLock identity theft protection: Discover and restore identity theft.

Note: Norton’s identity protection features are only available in the USA.

Conclusion: Is Norton the best anti-spyware software of 2023?

Yes, Norton is the best anti-spyware program in our test.

Modern security software needs to offer far more than just anti-spyware protection. By combining device security, online privacy, and identity theft protection, Norton is the best internet security suite you can buy.

Bitdefender Antivirus Review

Bitdefender’s antivirus engine is famous for its outstanding protection, many security features, and multi-layer ransomware protection, while being light on system resources.


Bitdefender antivirus has a 95% malware protection score. This is the average of the 10 most recent protection tests by AV-Test. It puts Bitdefender ahead of all competitors, except Norton, McAfee, and Kaspersky.

Bitdefender’s real-time protection feature, Advanced Threat Defense, offers solid virus protection and advanced ransomware protection.

It does not rely on traditional malware detection methods, which use virus signatures. Instead, it continuously monitors the behavior of apps. The apps are blocked if Bitdefender spots an anomaly, such as code injection.

This method offers excellent malware detection rates while having a low number of false positives. During our own tests, Bitdefender detected the latest malware types instantly.


Bitdefender’s firewall can block inbound and outbound connections on local networks and the internet. On top of that, Bitdefender detects and blocks port scans that hackers use to find open ports on your device.


Bitdefender’s free VPN has a data limit of 200 MB / day. That equals 5 minutes of streaming at 720p or the opening of 100 websites.

Bitdefender uses Aura’s VPN tech but has built its own apps. The VPN is fast, secure (AES-256 & HydraVPN), private (no logs), allows torrenting, and has a few extra features: start-up, auto-connect, kill switch, and split tunneling.

You will have to buy Bitdefender Premium VPN or Bitdefender Premium Security, for unlimited data transmission.

Password Manager

Bitdefender’s password manager is sold separately. It is not included with Bitdefender Antivirus Plus, Internet Security, or Total Security. To get it, you have to buy it separately or buy Bitdefender Premium Security.

Prices & Packages

  • Bitdefender Antivirus Plus starts at € 15 (Europe) or $ 15 (USA). It offers antivirus and anti-phishing. It protects 1 to 10 PCs.
  • Bitdefender Internet Security starts at € 19 (Europe) or $ 25 (USA). It adds a firewall and parental controls. It protects 1 to 10 PCs.
  • Bitdefender Total Security starts at € 35 (Europe) or $ 40 (USA). It adds an optimizer and support for other OS. It protects 5 to 10 devices.
  • Bitdefender Premium Security starts at € 55 (Europe) or $ 60 (USA). It adds an unlimited VPN and password manager. It protects 10 devices.

Note: There is also Bitdefender Antivirus Free Edition, the free version of Antivirus Plus. This is the best free antivirus software. But honestly, it’s very basic and not much better than the built-in Microsoft Defender. So instead, we recommend Bitdefender’s paid antivirus software. It’s worth it.

Bonus Features

  • Online threat prevention: Anti-phishing protection for malicious sites.
  • Vulnerability scan: Scan the operating system, apps, and network.
  • Ransomware remediation: Restore files encrypted by ransomware.
  • Anti-spam: Customize anti-spam for Outlook and Thunderbird.
  • Safepay: Open a secure browser for online banking protection.
  • Video and audio protection: Webcam and microphone protection.
  • Anti-tracker: Remove tracking cookies via this browser extension.
  • Parental advisor: Monitor the digital activities of your kids.
  • Anti-theft: Locate and wipe your devices remotely.
  • One-click optimizer: Clean up your hard drive and browsers.
  • Data protection / file shredder: Permanently remove files.

Conclusion: Is Bitdefender the best anti-spyware software of 2023?

Bitdefender is one of the best antivirus software in our test. Its anti-malware, firewall, password manager, and VPN are highly advanced. On top of that, there are tons of extra features.

However, Bitdefender can be expensive. It sells its password manager and unlimited VPN separately or as part of its Premium Security suite. This makes it pricey if you want all security features.

By contrast, Norton includes these features for free.

You can try Bitdefender risk-free, thanks to its 30-day return policy.

  • Speed impact: 85%. McAfee averaged 5.85 out of 6 in the last 10 performance tests. So it has a minimal impact on your PC’s speed.

  • Price: 95%. McAfee offers better value for money than most competitors, except Kaspersky, which is slightly cheaper.

McAfee Antivirus Review

McAfee allows you to protect an unlimited number of devices.


McAfee is among the few brands with a 100% anti-malware test score. It has improved its cybersecurity tools a lot in recent years. Since April 2020, it has achieved a perfect 100% score in every protection test by AV-Test.

In our tests, McAfee offered reliable protection against malicious software and cyber threats. Which means that it successfully detected and removed all offline and online threats.

McAfee can reach these results because of its Scan Engine:

  • It runs antivirus scans and matches files with malware samples.
  • It executes malicious code in a safe environment, called a sandbox.
  • It applies heuristic techniques to recognize new malicious threats.
  • It removes dangerous code from corrupted files.


McAfee’s excellent firewall filters both in- and outgoing traffic. On top of that, McAfee hides open ports so that hackers can’t identify unused ones with their port scanning techniques.


McAfee’s VPN, Safe Connect, is free and offers unlimited data. It’s fast, secure (AES-256), private (no activity logs), has servers in 45 countries, works with Netflix on many servers, and allows torrenting.

However, it’s not perfect. For instance, not all security features (like the kill switch and split tunnel) are available on all operating systems. And if you turn off auto-renew, the VPN is limited to 500 MB / day.

Password Manager

McAfee’s cross-platform password manager, True Key, is one of the best.

Creating and storing passwords is easy. Auto-filling them is accurate. And you can use biometrics (facial recognition and fingerprint scanner) to log in. As a result, it can compete with the best password managers, like Dashlane. 

Prices & Packages

  • McAfee Basic costs € 30 (Europe) or $ 30 (USA). It offers antivirus, anti-phishing, firewall, password manager, and VPN. It protects 1 device.
  • McAfee Essential (called McAfee Plus in Europe) costs € 40 (Europe) or $ 40 (USA). It adds no additional features but protects 5 devices.
  • McAfee+ Premium costs € 45 (Europe) or $ 45 (USA). It adds a personal data cleanup and protects unlimited devices.
  • McAfee+ Advanced costs € 65 (Europe) or $ 80 (USA). It adds identity theft protection and protects unlimited devices.
  • McAfee+ Ultimate costs $ 190 (USA) and is not sold in Europe. It adds more identity theft protection features and protects unlimited devices.

McAfee is in the process of renaming its products. So in some countries, you’ll be shown McAfee Total Protection instead, which has the same features as McAfee Basic and Essential.

Bonus Features

  • Secure Apps: A vulnerability scanner for security updates.
  • App Boost: A performance boost for apps you frequently use.
  • Browser Security: An anti-phishing browser extension.
  • Web Boost: A browser extension that stops videos from auto-playing.
  • Tracker Remover: A feature that deletes tracking cookies.
  • ID Protection: A dark web scanner for your personal data.
  • File Shredder: A shredder that can delete files securely.
  • File Lock: An app that creates password-protected file vaults.
  • Anti-Spam: An anti-spam feature for Outlook and Thunderbird.
  • Safe Family: A parental control feature to monitor and protect kids online.

Conclusion: Is McAfee the best antivirus software of 2023?

McAfee is one of the best antivirus software in our test. Its virus protection gets perfect scores, its password manager is excellent, its unlimited VPN is included for free, and its design is both user-friendly and beautiful.

On top of that, its premium and advanced plans allow you to protect an unlimited number of devices and offer extensive privacy and identity protection features, especially in the United States.

Panda Antivirus Review

  • Malware protection: 99%. Panda averaged 99.9% in the malware protection tests. It is excellent at detecting and removing malware.
  • Speed impact: 99%. Panda averaged 99% in the performance tests. So it has almost no impact on your PC’s speed.
  • Features: 100%. Panda offers anti-malware, anti-phishing, firewall, unlimited VPN, password manager, parental controls, and more.
  • Price: 75%. Panda offers the most flexible pricing of all brands. But, if you want all the security features, Norton is more affordable.

Panda Dome Antivirus Review

Panda offers the most flexible pricing for its antivirus packages.


Panda antivirus scored 99.9% in the real-world protection tests. However, it does have with a higher number of false positives than its competitors, which means that it frequently mistakes harmless software for malware.

This result is the average of all tests by AV-Comparatives since 2020. Usually, we quote AV-Test, another independent test lab. However, Panda does not take part in their tests. Both labs independently test the malware scanning capabilities of free and premium antivirus programs.

Panda combines big data, artificial intelligence, and machine learning to scan all apps on your device. This allows it to counter known malware and advanced emerging threats like zero-day malware, ransomware, and API’s.


Panda’s firewall filters incoming and outgoing connections on local networks and the internet. It automatically assigns permissions to each application based on its risk level. But you can edit the rules per app.


Panda includes a free VPN with its antivirus products. However, this built-in VPN is limited to 150 MB / day, which isn’t a lot. That equals about 4 minutes of streaming at 720p or the opening of 75 websites.

Like Bitdefender, Panda’s VPN uses Aura’s technology. This means that the VPN is fast, secure (AES-256 & HydraVPN), private (no logs), and allows torrenting. However, it lacks extra features like a kill switch, making its € 50.00 price expensive.

Password Manager

Panda’s password manager is excellent. Generating and storing passwords is easy. Auto-filling them is accurate. And both two-factor authentification and biometrics login is supported.

The design of the browser extension for Google Chrome and Mozilla Firefox is identical to the apps on Android and iOS, which gives it a seamless experience across all major operating systems.

Prices & Packages

  • Panda Dome Essential starts at € 17 (Europe) or $ 24 (USA). It offers antivirus and a firewall.
  • Panda Dome Advanced starts at € 23 (Europe) or $ 28 (USA). It adds anti-phishing and parental controls.
  • Panda Dome Complete starts at € 35 (Europe) or $ 43 (USA). It adds a password manager and system optimizer.
  • Panda Dome Premium starts at € 60 (Europe) or $ 67 (USA). It adds an unlimited VPN and update manager.

All of Panda’s plans can be upscaled to an unlimited number of devices.

Bonus Features

  • Safe browsing: Block malicious URLs and phishing sites.
  • Dark web scanner: Search the dark web for your email address.
  • PC cleanup: Delete cookies or files with the system optimization tools.
  • Wi-Fi protection: Check and improve the security of your Wi-Fi network.
  • Anti-theft: Locate your PC if it is lost or stolen.
  • File encryptor: Encrypt sensitive files with a password.
  • File shredder: Securely and permanently delete files.
  • USB protection: Scan a USB drive for malware.

Conclusion: Is Panda the best antivirus software of 2023?

Panda is one of the best antivirus software in our test. We really like the password manager and flexible pricing.

But we prefer Norton, because it includes an unlimited VPN at a lower price. And because it offers better protection for Macs and mobile devices.

However, if you only have a Windows PC to protect, Panda’s excellent internet security suites are a great choice.

You can try Panda risk-free, thanks to its 30-day money-back guarantee.

  • Price: 100%. Kaspersky Plus is the most affordable way to protect a Windows PC with all essential features, including an unlimited VPN.

Kaspersky Anti-Virus Review

Kaspersky offers exceptional online security at a low price.


Kaspersky antivirus has a 100% malware protection score. This was its average in the independent tests by AV-Test since October 2016. This puts it ahead of all other antivirus companies, except Norton and McAfee.

It can offer such excellent malware protection through its triple-layer protection system:

  • Locate vulnerabilities and threats proactively via heuristic analysis.
  • Block cyber threats in real-time.
  • Instantly isolate and remove dangers.


Kaspersky has one of the most advanced firewalls in the industry. It will filter incoming and outgoing network activity on local networks and the internet. And although it works perfectly on the default settings, there are plenty of customization options too.


Kaspersky includes an unlimited VPN for free with Plus and Premium.

Like Bitdefender’s VPN, it uses Aura’s technology. Therefore, the VPN is fast, secure (AES-256 & HydraVPN), and allows torrenting (P2P). It also features several extra features: Auto-connect, kill switch, smart protection, and website protection.

However, by default, Kaspersky will collect information on your device, location, VPN server, and WiFI network (including IP and DNS settings). It does this to improve product quality, send ads and create marketing offers.

Password Manager

Kaspersky’s password manager is excellent. Creating and storing passwords is easy, and auto-filling them is accurate. Unlike Norton and McAfee, Kaspersky’s password manager is a desktop app rather than a web app. But that doesn’t get in the way of a great user experience.

Prices & Packages

  • Kaspersky Standard starts at € 20 (Europe) or $ 28 (USA). It offers antivirus, anti-phishing, and a firewall. It protects 1 to 5 devices.
  • Kaspersky Plus starts at € 26 (Europe) or $ 37 (USA). It adds a firewall and an unlimited VPN. It protects 1 to 5 devices.
  • Kaspersky Premium starts at € 32 (Europe) or $ 48 (USA). It adds identity protection and parental controls. It protects 1 to 20 devices.

Kaspersky has replaced the old product names Kaspersky Anti-Virus, Internet Security, and Total Security, with Standard, Plus, and Premium.

Bonus Features

  • Internal scan: Scan for worms, spyware, rootkits, and other malware.
  • External scan: Scan external drives, like a hard disk or USB drive.
  • Vulnerability scan: Scan your device for security risks.
  • Kaspersky protection: A hardened browser extension for secure banking.
  • Parental controls: Monitor and protect your children online.
  • Webcam protection: Block programs from accessing your webcam.
  • Private browsing: Block and remove tracking cookies in your browser.
  • Backup and restore: Backup files to cloud backup storage.
  • File encryption: Lock sensitive files in a secure vault.
  • File shredder: Permanently delete files via advanced protocols.

Conclusion: Is Kaspersky the best antivirus software of 2023?

Kaspersky offers excellent antivirus protection. Its anti-malware is industry-leading, its firewall and password manager are excellent, and it provides a wide range of extra features.

However, its VPN privacy policy is disappointing. A VPN is a privacy product and shouldn’t be used for marketing. On top of that, Kaspersky struggles with the tensions between the West and Russia, due to the war in Ukraine.

Therefore, we prefer Norton, which includes an unlimited VPN for free in its antivirus suite, doesn’t track what you do online, and isn’t caught up in a geopolitical struggle.

You can try Kaspersky risk-free, thanks to its 30-day return policy.

Test score comparison

We’ve scrutinized the performance metrics from the ten latest test scores of all antivirus brands, courtesy of the German anti-malware test lab, AV-Test. They consider three key factors:

  • Protection (1-6): Antivirus protection against malware attacks.
  • Performance (1-6): System slowdown caused by the antivirus.
  • Usability (1-6): Frequency of false alarms and disruptions.

We used their results, and this formula, to calculate the final score:

Final Score = 60% Protection + 20% Performance + 20% Usability.

Any brand not mentioned in the table did not participate in AV-Test’s examination, which is usually a red flag. Most renowned brands, barring Panda, ESET, and Sophos, submit to this test.

Final Score

Price comparison

We’ve evaluated the pricing of leading antivirus solutions for Windows. To ensure a fair analysis, we’ve considered the cost of securing a Windows PC with fundamental protections:

  • Anti-malware
  • Anti-phishing (web protection)
  • Firewall
  • Password manager
  • Unlimited VPN (no data limit)

A few notes:

  • Some brands are missing features, lowering their value for money.
  • Prices are second-year prices in the USA, without first-year discounts.
  • Prices are rounded up for readability (e.g., $99.99 becomes $100).

Brands may have different pricing structures outside the US. Check their respective websites for these details.

User reviews

We’ve compared user feedback for all antivirus brands using TrustPilot, a popular user review platform. Be mindful of these results as some brands might try to boost their ratings artificially.

We remain skeptical about unusually high ratings, particularly from brands like TotalAV, known for their aggressive marketing.

Scores ranging between 4.0 and 4.5 are considered acceptable and credible. Higher scores raise suspicion, while lower scores might suggest subpar products or customer service. For example, the scores for McAfee raise eyebrows.

What is antivirus software?

Antivirus software, a critical component in digital security, is a set of programs designed to detect, prevent, and remove malicious software, commonly known as malware. In the evolving world of cyber threats, it safeguards against viruses, trojans, worms, ransomware, spyware, adware, and other nefarious cyber intrusions. More advanced antivirus software also provides protection against phishing attacks, firewall breaches, and online identity theft.

The software is an essential tool for anyone navigating the online world, from individual users to large corporations, as it keeps sensitive information, data, and systems safe from harmful cyber threats.

For more, read our blog post on what antivirus software is.

How does antivirus software work?

Antivirus software functions by using a variety of detection methods to identify threats on your device or network. Upon identification, it isolates and eliminates the threats before they can inflict damage.

The software is capable of continuous scanning and monitoring in the background, providing real-time protection while minimizing performance impact. Let’s delve into some of the detection techniques.

Signature-based detection

Signature-based detection, one of the oldest methods, involves matching harmful software with a database of known malware signatures. A signature is a unique string of code or ‘fingerprint’ that identifies a specific type of malware.

Antivirus software scans files and applications, comparing them to its database of signatures. If a match is found, it indicates the presence of malware, and the file or application is quarantined or removed.

Heuristic analysis

Heuristic analysis is a more proactive method, designed to catch new, or ‘zero-day’ malware, which hasn’t been previously identified and added to the signature database. Instead of matching signatures, heuristic analysis examines code and file behavior for characteristics typical of malware.

It identifies suspicious or abnormal activities, such as attempts to access sensitive data, modify system files, or replicate itself, which could suggest the presence of malware.

Behavior-based detection

Behavior-based detection, also known as behavior blocking, monitors the actions of applications in real-time. Rather than examining the code, it observes what an application does once executed.

If an application engages in activities typically associated with malware, such as encrypting large amounts of data quickly (a sign of ransomware) or trying to gain elevated system privileges, the antivirus software intervenes, blocking the suspicious actions and quarantining or removing the offending software.

For more, read our blog post on how antivirus software works.

What’s the difference between anti-spyware and antivirus software?

While the terms “anti-spyware” and “antivirus” are often used interchangeably, there are nuanced differences between them, primarily in their focus areas. However, it’s important to note that modern antivirus solutions encompass anti-spyware capabilities, and as such, the terms have become more synonymous over time.

Antivirus software, in its traditional sense, is designed to protect against a wide array of malicious software or malware, which includes viruses, worms, trojans, and more. On the other hand, anti-spyware software specifically targets spyware threats, a type of malware that quietly monitors your activities and collects personal and confidential information without your consent.

Spyware can be particularly harmful as it can track and record keystrokes (potentially capturing passwords and other sensitive data), browse your files, read your emails, and even hijack your web browser settings. The danger with spyware lies not only in data theft but also in the violation of personal privacy.

Another form of spyware, called Potentially Unwanted Programs (PUPs), are also worth noting. PUPs are software that, while not explicitly malicious, often perform activities that interfere with user experience or compromise security. They typically find their way onto your device via software bundling, sneaking into the installation of another program.

PUPs can include adware, junkware, or unnecessary toolbars that slow down your device or inundate you with ads. Some PUPs can act as a form of spyware, covertly collecting your personal data and browsing habits and sharing them with third parties without your knowledge. This makes it crucial to have a reliable antivirus or anti-spyware program, capable of identifying and removing PUPs from your system, thereby safeguarding your online privacy.

However, as the cyber threat landscape has evolved and become more complex, the line between antivirus and anti-spyware software has blurred. Today, comprehensive antivirus solutions include robust anti-spyware capabilities as part of their security suite. They not only protect against traditional viruses but also against spyware, ransomware, phishing attempts, and other online threats.

In other words, while all anti-spyware tools form part of an antivirus software, not all antivirus tools were initially equipped with anti-spyware functionality. This is no longer the case, and currently, choosing a well-rounded antivirus solution ensures you get robust anti-spyware protection too. It’s like getting a multi-purpose shield that safeguards against a myriad of online threats, spyware included.

How do we test antivirus software?

Our evaluation process for antivirus software is thorough and multifaceted. We assess each product on six crucial elements, each carrying a different weightage, to ensure a comprehensive review. These elements include:

  • Anti-malware protection (30%)
  • Security and privacy features (30%)
  • Speed impact (10%)
  • False positives (10%)
  • Price (10%)
  • Ownership and reputation (10%)

This methodical approach allows us to provide a well-rounded perspective on each software’s capabilities, performance, and value, helping users make an informed choice.

Anti-malware protection (30%)

The effectiveness of an antivirus program in providing robust anti-malware protection forms a critical part of our evaluation process. To ensure a rigorous assessment, we employ a two-pronged approach: conducting our own in-house testing and reviewing results from AV-Test, an internationally recognized testing lab.

In-house testing

Our in-house testing process is designed to closely mimic real-world scenarios. We expose the test PC to hundreds of malware samples via a USB device, testing the antivirus software’s ability to detect and neutralize them. This provides an understanding of how well the software can identify and eradicate threats that may land on a system via external storage devices, a common occurrence in everyday usage.

Additionally, we simulate active malware attacks by executing malware files and initiating ransomware attacks on the system. This allows us to evaluate the software’s real-time protection capabilities and its efficiency in halting threats before they can inflict damage. Such a test is vital because modern-day cyber threats often come disguised and may be triggered by seemingly innocuous activities like clicking on a link or downloading an email attachment.

AV-Test results

In addition to our in-house tests, we also consider AV-Test results in our assessment. AV-Test is a highly respected independent IT security institute known for its rigorous testing of antivirus software across various platforms, including Windows, Mac, and Android.

These results give us an understanding of the antivirus software’s performance against a wide range of malware in diverse environments and under different conditions. By integrating AV-Test results into our evaluation, we ensure our review is not only comprehensive but also aligned with global testing standards.

Security and privacy features (30%)

Assessing an antivirus software’s security and privacy features forms a significant part of our evaluation process, given the multitude of threats that users face online today. Here’s a look at some of the key features we examine:

Web protection (anti-phishing)

Web protection, particularly anti-phishing capabilities, is vital in protecting users from malicious websites that try to steal sensitive information. We test this by visiting a variety of known phishing websites and observe whether the software successfully blocks access and alerts the user about the potential threat.


A firewall serves as a first line of defense, monitoring network traffic and preventing unauthorized access to your system. We test firewalls by attempting to connect to the test system from another device, assessing whether the software effectively blocks unauthorized connections while allowing safe ones.

Password manager

Password managers store, generate, and auto-fill complex passwords, enhancing security while simplifying user experience. We test this feature by evaluating its ease of use, password generation capability, and effectiveness in auto-filling passwords across various websites and applications.

Virtual private network (VPN)

VPNs protect privacy by creating a secure, encrypted connection, thereby shielding your data from prying eyes on public networks. We test VPNs by checking their encryption standards, assessing connection speeds, and verifying their no-logs policies to ensure they don’t track user activities.

Parental controls

Parental controls help safeguard children online by restricting access to inappropriate content and setting internet usage limits. We assess this feature by trying to access various age-inappropriate websites and attempting to override set usage limits.

Identity theft protection

This feature alerts users to potential identity theft by monitoring personal information online. We test this by entering user details into a monitored category and checking if the software sends an alert when this information appears in suspicious contexts online.

Secure cloud storage (cloud backup)

Secure cloud storage provides a safe space for users to back up important files, protecting them from loss due to ransomware or hardware failure. We test this feature by backing up and restoring files, checking for data integrity and encryption levels.


Anti-ransomware tools prevent ransomware from encrypting your files, effectively rendering them inaccessible. We test this feature by simulating a ransomware attack to see if the antivirus software successfully thwarts it.

Dark web monitoring

Dark web monitoring scans the dark web for your personal information, alerting you if it appears in data breaches. We verify this feature by checking if alerts are triggered when simulated personal information is found in places associated with data breaches on the dark web.
