Features & Capabilities

SafeToOpen is a lightweight browser extension that delivers proactive, real-time protection against phishing, scams, and malicious websites. Powered by VisionAI and backed by one of the largest live feeds of unsafe domains, it detects zero-day threats, blocks malicious pages before they load, and prevents submission of passwords and payments on risky sites.
