BROWSER EXTENSION
APIVoid Browser Protection monitors every website you visit and blocks threats before they load. Stop phishing pages, malicious websites, and downloads of unsafe file types, all with zero configuration required.
Smart Blocking Rules
APIVoid Browser Protection analyzes every URL you visit and blocks suspicious destinations. From risky TLDs to IP-based URLs, phishing domains, and dangerous file downloads.
Block domains ending with a known risky top-level domain, commonly used in phishing campaigns.
Block URLs where the host is a raw IPv4 address, a common sign of potentially malicious host.
Block domains like pages.dev or free dynamic DNS domains like hopto.org, often abused for phishing.
Block downloads of dangerous file types such as .hta, .bat, .vbs, .ps1, .wsf and many others.
