Chromebooks are already extremely secure.

Sure, it’s not completely infallible 3 Reasons Why Chromebook Does Not Solve Digital Security Issues 3 Reasons Why Chromebook Does Not Solve Digital Security Issues Google's ChromeOS is probably the most secure operating system in the world (at the cost of some limited functionality). Unfortunately, ChromeOS isn't a panacea, and serious security concerns about the platform remain. Read More , nothing is. But you can easily make the argument that Chromebooks are the most secure laptops on the market.

However, just because they’re secure at a hardware level doesn’t mean you can’t improve their security at a user level.

Here are four ways to make your Chromebook even more secure Securing Your Chromebook With Two Easy Tweaks Securing Your Chromebook With Two Easy Tweaks One of the most touted benefits of a Chromebook is its security. But are there any steps that owners can take that will improve and enhance the current level of protection? Read More .

1. Deploy Guest Mode

Guest Mode’s primary purpose is to allow other people to use your machine without using your Google Account. As such, it keeps your data on Google’s suite of apps safe from prying eyes.

But Google itself likes to pry. Anything you do on your Chromebook — whether it’s saving a song to Google Drive, visiting a particular website, or installing an app from the Web Store — is logged against your Google Account. Google then uses the mountain of information to show you (supposedly) relevant ads.

If you’re planning to do things you don’t want Google to log against your account, the best approach is to use the Guest Mode. Unlike Incognito Mode Guest Mode vs. Incognito Mode in Chrome: What's the Difference? Guest Mode vs. Incognito Mode in Chrome: What's the Difference? Chrome offers Incognito mode and Guest mode for private browsing. While they're similar, some key differences separate them. Here's when to use which one. Read More , which still sits within your user profile on your machine, Guest Mode is in no way attached to your account.

Guest Mode still lets you download files and browse the entire web. The only restriction is you cannot install new apps.

To use Guest Mode, press Ctrl + Shift + Q if you’re already logged in, or select Browse as Guest from the shelf on the main login screen.

If Guest Mode is not enabled on your Chromebook, head to Settings > People > Manage Other Users > Enable Guest Browsing.

2. Change the Default Search Engine

If using the Guest Mode is either too extreme or too inconvenient, you can at least replace the default search engine.

There are several search engines that don’t track you 7 Google Search Alternatives and Their Trademark Features 7 Google Search Alternatives and Their Trademark Features Are you a die-hard Google user? Give these alternative search engines a try. From privacy to helping out charitable causes, these search engines could give you some reasons to change the way you browse. Read More , store your IP address, or profile their users. Two of the most popular are DuckDuckGo and Startpage. DuckDuckGo draws its results from more than 50 “high-quality” sources, while Startpage removes all your identifying information then submits the search term to Google’s search engine.

If you value the depth and breadth of Google’s results, the latter is probably the best option.

To change your Chromebook’s default search engine, navigate to the homepage of the engine you want to use and perform a search for any word or phrase. Doing so will make the search engine a selectable option in the browser’s list of providers.

Next, right-click in the address bar and choose Edit Search Engines. Scroll down and search through the list of domains under Other Search Engines until you find your provider. Finally, click Make Default.

3. Change the DNS Service

Chromebooks do allow you to hard-configure the DNS service, but the option is buried away and not easy to find.

Changing your DNS has significant benefits: it can improve your connection speed, increase uptime, and sometimes even let you access geo-blocked content.

Security-wise, the benefits can be split into three categories:

  • Domain Name System Security Extensions (DNSSEC) — DNSSEC prevents apps and DNS resolvers from falling victim to fake or compromised DNS data. Most ISP DNS services do not offer this feature.
  • Phishing Protection — Obviously, most browsers now have built-in phishing protection, but it adds an extra layer of safety.
  • Parental Controls — Parental controls are particularly useful if you have young children who regularly use your Chromebook. The laptops don’t have any native parental controls.

Not all public DNS services have all the benefits. For example, Google DNS and OpenDNS both support DNSSEC, but only OpenDNS supports parental controls and anti-phishing. Do your research before selecting one.

To change the DNS service on your Chromebook, go to Settings > internet Connection, click the name of your Wi-Fi network, then click on your name again in the drop-down menu.

On the new window, click the Network tab. At the bottom of the window, you can choose either Automatic Name Servers (your ISP’s), Google Name Servers, or Custom Name Servers.

You need to repeat this process for every Wi-Fi network you use.

Read More security and privacy, installing a few third-party apps/extensions can make a huge difference.

Here are my top three picks that every Chromebook owner should be using.

HTTPS Everywhere

HTTPS Everywhere is a joint development between Tor Project and the Electronic Frontier Foundation.

The premise is simple: the extension automatically converts insecure HTTP domains to secure HTTPS domains. The switch will help protect you against surveillance and domain hijacking.

Privacy Badger

Privacy Badger is another app from the Electronic Frontier Foundation. It’s an anti-tracking extension that prevents spying ads and invisible trackers from loading on a page.

You can even customize which permissions are allowed on a granular case-by-case basis for each site. For example, you can block access to your microphone and location while still allowing a site to load images and automatically download content.

Spotflux

Spotflux is a free VPN service 7 Completely Free VPN Services to Protect Your Privacy 7 Completely Free VPN Services to Protect Your Privacy If you're looking for a free VPN, the choices are currently limited, with many services switching to a paid model. These free virtual private networks can be used to avoid region blocking and more. Read More . It uses the developer’s security cloud rather than P2P VPN like Hola.

In addition to the VPN feature, it also encrypts all your browsing using SSL and hides your IP address from sites. The app is ad-supported.

How Do You Make Your Chromebook Secure?

When combined with a Chromebook’s hardware-level security, following my four tips and installing the three extensions will turn your laptop into a fortress. It would arguably become the safest and most secure way of accessing the world-wide web.

However, my list isn’t exhaustive. There are always more steps you can take to make yourself more secure.

    So while you can change DNS, guest mode, etc, your ISP still knows what you're doing and is tracking you. Do you have any recommendations for a VPN?

    For the DNS change, how would you do it if you're on a wired connection? You can update your modem/router with DNS settings but is that needed in the browser as well?

    Hi, Dan.
    I've used Privacy Badger before, and for a long while then. Over time I gravitated to Ghostery, and eventually dropped PB. (mmmm...peanut butter)

    So what do you think about Ghostery compared to Privacy Badger? I think I began to like it better because I could see info on each of the items it blocks, plus it constantly seems to be adding new items.

    That said, I would rather have the most secure app regardless of how much info it shows me.

    Learned several new things in this article. Thanks!
