Best browsers for privacy and security

Every single day you visit blogs, shop online, pay your bills, or visit social media platforms. However, what you do online isn’t a secret. Every click you make is tracked by websites, advertisers, ISPs, and government agencies. A better browser can help you take your privacy back. Here are some private browsers and their security features.

Our rating system: We've given each browser a rating of one to five stars (⭐). These ratings are the author's subjective evaluation of the browser's security and privacy. However, we've also considered the browser's features. A five-star browser may not be perfect, but it represents one of the most privacy-oriented browsers out there that also has great user features.

Popular browsers

While it is entirely possible to tweak Google Chrome, Safari or even Microsoft IE with plugins and advanced settings for security and privacy, these are far from their key features. Besides, the further you go from the default settings, the easier it gets to identify your unique online fingerprint. Still, these are the biggest names on the market and cannot be ignored.


Chrome home page

Google Chrome was launched in 2008 and is now the undisputed leader in browser market share. That was predictable, as in many ways it is a fantastic solution with robust security and vast possibilities for integration and fine-tuning.

However, Chrome is never going to be the best privacy browser. It is developed by the company whose business model primarily consists of spying on its users to profile them for targeted advertising. What Chrome's privacy notice says, in a nutshell, is that it is essentially just spyware for Google.

Of course, you can deve deep into Chrome’s complex privacy preferences and choose among the multitude of extensions for additional layers of security. However, you will have to work for it as well as trust Google to refrain from meddling with its privacy policy while you’re looking away.

Chrome is available for Windows, Linux, macOS, iOS, and Android.

Our rating (out of 5): ⭐⭐


Safari home page

Safari does quite well in terms of maintaining your online privacy – mainly because Apple is mostly focused on its hardware business and doesn’t rely on aggressive online advertising. For instance, it prevents third-party sites from leaving data in your cache by default. It’s also strong in the security department, running web pages in separate processes to prevent malicious code on one page from damaging the entire browser or accessing your data.

Safari does use the open-source Webkit framework, but this is limited to its function as a rendering engine. The rest of Safari is closed-source, and Apple did participate in the NSA’s PRISM program, so placing your trust in it may not be the best idea.

Safari is available for macOS and iOS.

Microsoft Internet Explorer/Edge

Internet Explorer is a joke and has memes to prove it. Meanwhile, its touted successor Edge has only had two updates since the beginning of 2017, which does nothing to assure Edge users of its security strengths.

Like the other mainstream names, both IE and Edge allow blocking pop-ups and sending a “Do Not Track” request. That being said, both Microsoft’s browsers are closed-source, so there’s no telling what other types of surveillance widgets might lurk within them.

Internet Explorer is available for Windows but no longer developed. Edge is available for Windows, Windows Mobile, and Xbox One, with beta versions available for Android and iOS as of April 2018.

Our rating (out of 5): ⭐⭐⭐


Firefox home page

Firefox is the only mainstream open-source browser, and its code has been thoroughly audited. Despite it still being a step behind Chrome in the security area, the gap is almost negligible. Like other major market players, it offers a private browsing mode, which includes tracking protection. It also has an impressive collection of security-focused add-ons that can be used to make the Firefox experience safer.

The problem with using extensions for enhanced security and privacy is the above-mentioned threat of fingerprinting. But the upcoming canvas fingerprinting protection (or the existing Canvas Defender add-on) should ease this issue in Firefox.

If you’re looking for a secure Android browser, the stripped-down Firefox Focus is probably your best choice. Released in 2016, it automatically blocks most online trackers and allows erasing your browsing history easily.

Firefox is available for Windows, macOS, Linux, Android, and iOS.

Security/privacy browsers

Using one of the major browsers may seem like the most convenient choice for everyday online activities, but all the names in this list are open-source and provide more privacy than Chrome, Edge/Internet Explorer or Safari.


Chromium logo

While Chromium has connections to Google, the tech giant does not own the builds that use its open-source code, and therefore the browser is not subject to the company’s default data gathering. However, it is practically impossible to guarantee the code is 100% clean and isn’t calling home, so although on paper Chromium looks good, the most privacy-conscious users may want to stay clear from anything related to Google.

The frequency of Chromium’s updates is unmatched, with a new one being released every single day. This is great for patching up vulnerabilities as soon as they emerge, but the updates require manual installation, which means the swiftness in threat mitigation ultimately depends on end users.

Chromium is available for Windows, macOS, Linux, and Android.

Opera home page

Opera runs on Chromium system and boasts a variety of security features to make your browsing experience safer, such as fraud and malware protection as well as blocking scripts and insecure add-ons.

The questionable component is the free built-in VPN that Opera acquired in 2016. Like many VPNs offered as free extras (here’s looking at you, Facebook!), it tracks bandwidth and usage logs. Besides, Opera itself is owned by a company based in a country notorious for privacy infringement.

Opera is available for Windows, macOS, and Linux.

Tor Browser

Endorsed by Edward Snowden, Tor is arguably the best known privacy-focused browser. It prevents unauthorized snooping with the help of its built-in hidden relay servers, comes with pre-configured security features and can run from a USB flash drive. Plus, it’s your gateway to the dark web if that’s your cup of tea.

Among other things, Tor is a good choice for avoiding fingerprinting. As long as you use the standard settings, do not add extra add-ons, and stick to the default window size (not the full-screen mode), one Tor Browser looks identical to another Tor Browser.

It’s important to remember that Tor is more of an advanced privacy solution than a secure one, as it includes no anti-malware technology and blocks plugins by design. One way to increase the security of Tor is using it together with a VPN for encryption. Learn more about how you can combine the two here.

Tor Browser is available for Windows, macOS, and Linux.

Brave home page

Brave is a relatively recent Chromium-based browser that packs quite a punch. It’s lightweight and yet offers a bunch of features, including a built-in ad-blocker, tracking protection, script blocker, and one-click anti-fingerprinting functionality.

Update: Brave now supports most Chrome extensions. While this is great for making the browser convenient and functional, users should still exercise caution and make sure they use extensions that respect their security and privacy.

Although Brave is open-source and nominally “de-Googled,” more suspicious users may not trust its Chromium base. The browser's upcoming advertising platform is also controversial, as Brave will be able to serve ads that profit the browser over any hosted by the sites you visit. However, they claim the opt-in system will also be designed so that users can contribute voluntary sums to the publishers they value the most.

Brave is available for Windows, macOS, Linux, Android, and iOS.

Waterfox home page

Waterfox is probably the most popular alternative browser based on the Firefox code; it was designed to take full advantage of 64-bit Windows computers back when Mozilla only offered a 32-bit version.

For the most part, Waterfox is the same as Firefox 56 when it comes down to looks and functionalities, which means it supports both legacy and new add-ons. It offers tracking protection and removes many of Firefox features that may decrease users’ privacy, such as Pocket and Telemetry.

The downside is Waterfox being stuck on the outdated Firefox version until at least 2019 – this may result in important security vulnerabilities being left unpatched.

Waterfox is available for Windows, macOS, Linux, and Android.

Our rating (out of 5): ⭐⭐⭐


With its highly customizable interface and functionality, many consider Vivaldi to be the power-user’s privacy browser.

The extensive customization options extend into Vivaldi’s privacy settings as well, allowing users to choose their default search engine and a wide array of other settings that impact your privacy. You can, for example, set different default search engines for when you’re using the regular and private browsing modes, and create different security settings for both of those search engines.

Although Vivaldi offers end-to-end encryption for syncing between devices, it does not have mobile device support yet. Due to hwo ti was developed, it is also compatible with most Chrome browser extensions.

Our rating (out of 5): ⭐⭐⭐⭐⭐


The philosophy behind the Epic browser is that it should ship with every privacy setting turned on by default. It’ll send “Do Not Track” requests, block cookies, and search via DuckDuckGo right from the start. You can configure the browser to improve its convenience at the expense of your privacy.

Epic takes this approach seriously, delivering on their promise of “extreme privacy”: no auto-syncing, no spell-check, no auto-fill – these and many other features come shut off or simply unavailable. This can make Epic hard to use for some users, but it’s certainly a very serious privacy tool.

It also makes your privacy gains measurable by tracking how many cookies it has blocked and who tried to send them.

Conclusion: Most private browsers

With privacy settings slightly tweaked and a few security add-ons installed, Firefox is easily the best private browser solution among the mainstream brands. If your anonymity needs are more advanced or you want to access the dark web, Tor is the one you’re looking for.

However, please bear in mind that none of these solutions are perfect – each browser has its respective strengths and weaknesses. To enhance your privacy and security online, you should use them in combination with other tools, such as tracker blockers and VPNs.

Other privacy tools

When choosing your new, more-secure browser, you may also want to consider which extensions it does or doesn't work with. There are a ton of excellent privacy tools out there, but they don't all work with every browser. To find the right browser privacy extensions for you, click here.

Another important privacy pool is a VPN. NordVPN's encrypted VPN tunnel will hide your traffic from hackers, ISPs, and governments, and protect you from numerous attacks as well. Use it in combination with a secure browser to ensure optimal online browsing security.
