Guardio

Guardio provides AI-powered personal cybersecurity protection through a browser extension and mobile app, defending consumers against phishing, malicious redirects, and deceptive websites in real time. Rather than relying on static blocklists updated periodically, Guardio’s detection adapts continuously as new threats emerge, aiming to catch scam and phishing sites that traditional browser security features miss.

The company protects over 1.5 million users globally, reporting that it intercepts roughly 825,000 threats and blocks around 320,000 malicious sites daily. Guardio has reached a $1.1 billion valuation with backing from investors including Tiger Global, and operates Guardio Labs, a dedicated research team focused on emerging consumer-targeted threats. The company’s team includes more than 100 engineers, creators, and researchers.

Guardio competes in the consumer-focused browser and online-safety category against both free browser-native protections and other paid consumer security tools. Its scale — 1.5 million users and daily threat-blocking volume in the hundreds of thousands — provides real, checkable evidence of usage, though as a consumer product rather than an enterprise security tool, it addresses individual users’ exposure rather than organizational risk directly.
