Guardio Review


Guardio is a Chrome browser extension that monitors your browser activity. It catches suspicious websites such as phishing sites or sites with hidden viruses, and will either send you a warning message explaining why this site is unreliable, or block you from entering it. Guardio monitors all of your online accounts and sites to make sure that nothing has been compromised, but it doesn’t cover your device system or downloaded files.

Why Choose Guardio

Guardio provides mobile, flexible protection that is just as mobile as you are. Because it’s a Chrome extension, you only need to install it once. After that, Guardio will be working wherever you log in to your Chrome account. It’s a great solution for anyone who skips frequently from laptop to tablet to smartphone. It’s also ideal for Chromebook users who can’t use an antivirus solution that requires a download.

Guardio is hardworking and reliable, but it doesn’t slow down your browsing speed or get in your way. Because it covers every website, Guardio is effective at protecting your social accounts along with the rest of your browsing activity. If you visit a site that is sketchy in any way, Guardio sends you an immediate message so that you can choose how to proceed. If it’s a phishing site or one infected with malware, you’ll be blocked from accessing it.

What Guardio Offers

  • Active extension analysis to spot and block harmful extensions
  • Data leak monitoring
  • Free basic scan
  • Active detection of suspicious or malicious sites
  • Automatic malicious site block
  • Cross-device and platform protection
  • Alerts about breached accounts
  • Individual, personalized reports about threats to your security

Guardio promises active, high-level monitoring for your Chrome browser. It automatically scans and analyzes the code in every site you visit to check for signs of suspicious activity. Malicious sites are automatically blocked, while ones that seem potentially dangerous are flagged, so you can choose how to continue. Guardio also constantly monitors your connection for third-party data leaks and acts to send an alert and plug the leak whenever it finds one. As a Chrome extension, Guardio is immediately available on every device you use, as long as you’re logged in to your Chrome account.


  • Free scan – Analyzes your security and vulnerability across all devices, and sends a free personalized threat report to alert you to any existing risks.
  • Full protection – Offers a detailed, personalized threat report about your security across all devices. Blocks malicious sites, removes harmful extensions, and notifies you about suspicious sites, as well as sending alerts if it detects that your account has been breached.

Ease of Use

Guardio’s simplicity is a virtue when it comes to ease of use. There are no complicated settings or controls to master. It works as a Chrome extension, so installing it is pretty easy. When you hit the ‘free scan' button, you'll be asked to install it as a Chrome extension, and the scan will start.

If you choose the paid plan, you’ll need to share your name, email address, and credit card information before you can get started. There’s nothing to configure or adjust – you’ll just receive personalized threat reports in your email folder and see alerts when you visit a suspicious or malicious site. When you see a warning about a site or extension, you can choose to override it.

Detection Rates and Reliability

Guardio doesn’t share its detection rates, but reviews on the Chrome webstore show that there are many happy users who rely on Guardio’s protection. The company calls itself “paranoid, so you don't have to be,” and it lives up to this motto by taking care to flag or block every suspicious site and ad.


Unlimited DevicesUp to 10 Devices

Guardio has 2 packages – a free scan option and a paid plan. The free scan is simply a taster that scans your device and your browser to check for malicious extensions, phishing sites, or viruses and sends a detailed threat report.

To really use Guardio, you need to sign up for the paid plan. You can choose to pay for the plan monthly, annually, or every 6 months, with discounts for the latter 2 subscriptions. Guardio does offer a 7-day free trial, and you can cancel your subscription online at any time, without any penalties or cancellation fees.

Value for Money

If you choose the annual subscription, you’ll be paying $47.88 each year, which is more than you’d pay for more features with McAfee. But unlike many antivirus solutions, Guardio also allows you to share your account details with friends and family, so you can cover many people and up to 10 devices with one subscription.

That said, Guardio’s big advantage is portability – because it works as a Chrome extension, it’s automatically up and running wherever you log in to your Chrome account. If you’re after a light antivirus that is always with you across every device, Guardio is good value for money. If you need all-round, full-featured protection on just a few devices, you can find that elsewhere at a lower cost.

Help and Support

Guardio promises human customer service through email and live chat. It’s not clear what the hours are for manned customer service, but when I logged in, the chat window told me someone would be there to help me in 1 hour. It’s easy to connect with Guardio – there are 3 different email addresses, depending on what type of question you have, and the live chat window is easy to open.

Guardio also has a help and support section on the website, with a set of FAQs. It’s easy to navigate and the answers are helpful, but there isn’t a very big selection of questions available. If you need more information than the simple answers provided here, you’ll have to get in touch individually.

Bottom Line

Guardio does a great job of delivering on cross-device and cross-platform website protection. It is reliable and effective at catching malicious or suspicious sites and covers all of your social media accounts and other channels without slowing down your internet speeds. Guardio is always active whenever you log into your Google Chrome account and doesn’t require any downloads.

Although it doesn’t have all of the extra security bells and whistles offered by some other antivirus solutions, Guardio is good for internet security. If you’re looking for flexible, lightweight antivirus protection that keeps you covered no matter where you go or what you do, Guardio is a sensible choice.
