Best overall
While Qustodio is an all-in-one security solution geared towards parents, its primary purpose is to block suspicious and harmful sites that are swarming with viruses and cybercriminals waiting to steal your personal information – and it keeps you safe through 29 filter categories.
Although features of a free plan are pretty limited in comparison to paid ones, they still include some hefty ones like screen time monitoring, setting time limits and restricted periods, as well as daily and weekly reports via email.
Being simple to install and set up on desktops and smartphones alike, Qustodio is also simple to use thanks to its intuitive, user-friendly interface.
Besides being somewhat short on features (no social media monitoring, no calls nor SMS monitoring, and no family locator), a free plan doesn’t support multiple devices – which is a deal-breaker if you want to monitor more than a single device.
Best for productivity
If you’re looking for a web filter that’ll help you be less prone to procrastination and live up to your expectation about being productive – BlockSite might be your best bet, and it’s free to boot.
BlockSite functions as an extension for Chrome, Firefox, and Edge, and an application for Android and iOS – and it stays true to its name and blocks sites for you. You can block each site, app, or keyword separately or block them all by category, receive usage reports about your devices, sync blocks across multiple devices, and much more.
Its core features include a custom blocklist, scheduled site and app blocking, and password protection. Also, BlockSite is incredibly intuitive and simple to use – you just need to copy the URL of the site you want to block, hit enter, and it’s on your blocklist.
While you can always enjoy the benefits of BlockSite completely free of charge, a premium plan aimed at businesses is coming soon and it’s going to cost a perfectly reasonable $1.99 per month.
Best for Chrome
With Guardio you can forget about all your worries about malware, phishing attacks, and identity theft – this lightweight extension for Google Chrome is created for safe and speedy browsing. Besides blocking suspicious sites and scams, it can also remove all unwanted pop-ups and similar annoyances that seek to ruin your mood.
While Guardio offers free trials with its paid plans, there is also a free tier and it will provide you with suspicious site detection, phishing alerts, personal data leaks history, on-demand scans, and some scope of customer support. On the downside, the plan is limited to one user only and excludes some pretty hefty security features of premium plans.
Also, while Guardio is sure to improve your browsing experience, sometimes it gets overprotective and blocks new yet otherwise innocent sites.
Best for households
Pretty popular with big families, FamiSafe is a premium parental control app for mobile devices that supports iOS, Android, Windows, Mac, and Kindle Fire. Depending on the plan, it can safeguard five or up to ten devices and allow parents to supervise their youngsters while protecting their right to privacy.
Some of FamiSafe’s core features include screen time control and tracking app usage, web filter (for Chrome and Safari), avid app blocker, real-time location monitoring, browser history, and digital activity reports. Plus, FamiSafe’s user interface is incredibly intuitive and you shouldn’t have any problem navigating around it.
However, there are a couple of drawbacks with FamiSafe such as the lack of logging calls and messages. Also, while all plans come with free trials they are terribly short lasting for three days only.
Best for inappropriate sites
To safeguard you from all sorts of cyber threats and corruptive content across the internet, OpenDNS takes a unique twist – it changes the DNS number in your control panel, and it can be done on the router level or for each individual device.
While this may sound a bit intimidating at first, as soon as you get your hands on OpenDNS’s simple-to-follow how-tos you’ll see it’s as simple as child’s play.
Once DNS is configured, the app will block all sites considered inappropriate due to falling into the categories such as violence, pornography, and anonymous proxy.
OpenDNS currently offers four plans, two of which are completely free: “OpenDNS Family Shield” and “OpenDNS Home” where the only major difference between them is that the first is pre-configured to block all adult content, while the other isn’t.
This means you can’t customize “OpenDNS Family Shield” in any way, which might be its main drawback – well, that and the absence of screen time control and real-time geolocation tracking feature.
With all OpenDNS web filter plans, you’ll get specialized customer support via email.
Best for Linux
If your PC runs on Linux or Unix and you don’t mind getting your hands on tech stuff right from the start, SquidGuard might be a good choice for you. First off, you’ll want to install and configure proxy-software Squid since SquidGuard can’t work without it.
In a nutshell, SquidGuard is a fast and flexible web filter, redirector, and access controller plugin for Squid and it works with Squid versions 2.x and 3.x.
With SquidGuard you’re free to determine multiple access rules with different restrictions for different user groups using the Squid cache. So, in addition to caching content, SquidGuard can filter the web and authenticate users and user groups. This filtering can cover all computers inside an organization, Windows and Macintosh computers alike.
SquidGuard utilizes Squid’s standard redirector interface and includes features such as configurable logging, a progress bar when compiling blacklists, full self-encrypting drive (SED) compliance for rewrite statements, and blocking of URLs with hostnames.
The long-awaited version of SquidGuard (1.4) promises new features – in addition to fixing old bugs, that is.
Best AV with filtering
Avast’s free antivirus is probably what Avast is best known for and it’s available on major platforms such as Windows, Mac, Linux, Android, and iOS. Also, in addition to free versions for all these platforms, Avast offers paid premium and business-oriented plans – however, they are pretty pricey.
Easy to install and effortless to use, Avast Free Antivirus comes equipped with smart scans for software, an automatic network inspector, proactive protection against ransomware, viruses, and malware, and cloud-based web filtering. There’s also a handy “Do Not Disturb” mode which will disable pop-ups while you’re enjoying watching a movie, listening to music, or playing a video game.
All in all, Avast Free Antivirus is a solid antivirus combined with a web filter and provides a superb level of security. However, if you wish to enjoy this “cloud-light, award-winning free virus protection” you’ll risk your sensitive browsing data being stolen and sold to other companies.
Best for web-borne threats
Comodo Dome Shield serves as the first line of defense against web-borne threats and blocks access to well-known suspicious sites providing URL filtering, advanced reporting, and analytics. They also offer a whole variety of their services for free, and they have been providing them for years.
Dome Shield’s threat database covers over 100 endpoints for filtering, meaning they don’t settle with DNS layer security for cyber threat intelligence. Plus, an ever-expanding, up-to-date fraud site database is sure to help users avoid fraudulent, malware-laden sites and phishing attacks.
While there's a bit of a learning curve, the intuitive, user-friendly interface and how-to guides make it less significant. What’s more, you’ll get complete control over web access and filtering - which we’re always glad to see.
Best for blocking everything
Cold Turkey makes promises to block everything that’s keeping you from being productive and helping you “reclaim your free time”. It’ll deliver on the promise through a free web filtering software for Windows and Mac that works splendidly on all browsers including Chrome, Firefox, and Edge.
With Cold Turkey, you can create and manage different blocklists (or allowlists) where each blocklist contains a different set of sites. Also, you can add unblocking date and time, which can be particularly useful if the administrator isn’t there to unblock the site for some reason.
The only handicap of Cold Turkey’s free plan is the absence of helpful features like scheduled blocks, application passwords, break timer, as well as life-long updates, and customer support via email - to get these features, you’ll have to go for a paid plan.
Best for Windows
