Features
Guardio offers antivirus and data protection through a browser extension and mobile app. It blocks malware downloads, detects and blocks suspicious websites, and flags data and protection vulnerabilities on your web activities. It also detects malicious email activity – as long as you use Gmail – and filters phishing messages coming from numbers not included in your contacts through the mobile app. These are some of Guardio’s main features:
Harmful website blocking: Guardio detects suspicious and low-authority websites and alerts you to them before allowing your browser to connect. You can choose to proceed to sites that are suspicious but which don’t contain known malware, while Guardio will completely block sites that contain malware.
Phishing alerts: Guardio automatically identifies phishing attempts, which may include spoofed websites or requests for passwords from low-authority web pages. The software will alert you to potential phishing activity so you can investigate further.
Data breach alerts: Guardio tracks past data breaches so you can see if your personal information or account credentials have been leaked. Detailed information is available on your account’s dashboard. If you sign up for VIP services, you’ll also receive real-time alerts when a new data breach occurs and exposes your information.
Machine learning: Guardio uses machine learning to adapt to new malware and other types of online threats. This adaptive technology enables Guardio to identify viruses that haven’t yet been added to the malware databases that most traditional antivirus software relies on.
Ease of Use
Guardio is very easy to use. Simply install the extension to Google Chrome and download the mobile app to your phone and Guardio’s website alerts and blocking features will go into effect immediately.
You can monitor your online activity and set up email, text and website threat alerts from your account’s dashboard. You can also see your browsing history and review any alerts or sites and pop-ups blocked by Guardio. The dashboard is very easy to navigate. If you share your account with multiple users, each user gets their own personal dashboard.

Detection Rates and Reliability
Guardio doesn’t measure its detection rates, but the software has had some notable successes. For example, Guardio detected a flaw in the popular Evernote extension for Google Chrome, which is used by 4.6 million people. Guardio also has a 4.3-star rating on Trustpilot after more than 4,000 user reviews.
Guardio’s machine learning capabilities help ensure that the software is able to stay ahead of new threats. Instead of relying solely on databases of known malware, Guardio is able to recognize and block new threats that haven’t been seen before but which look similar to documented malware.

Bottom Line
