Every time you visit any website, your local client exchanges information with our backend server in the form of hashes and hash prefixes. The figure below provides a general understanding of how the Browsing Security module works, using AdGuard for Windows as an example.īrowser extensions work differently, using the so-called Lookup API to check the pages you visit. We use hash prefixes for checks, not the opened URLs. Our server knows nothing about the websites that you visit. This protocol allows us to keep your personal data absolutely safe. We use the protocol Safe Browsing API version 2.2 for our work with filters. In AdGuard for Windows, Mac, or Android, we offer you the best possible protection by checking both the pages and all objects loaded on them.

Inexperienced users can easily become victims of fraudsters or hackers. So far, we have categorized more than 15 million sites, and our filters contain about 1.5 million phishing and malware sites. We have added special filters to the AdGuard app to protect you from malicious and phishing websites. Every day, tens of thousands of people fall prey to virus attacks or fraud on the Internet.
