Guardio ARR Hits $100 M

Guardio, a consumer cybersecurity startup focused on detecting malicious code—especially that generated by AI tools—has reached $100 million in ARR, according to its November 2025 funding announcement.  The company has 500,000 paying users, and its security engine blocks a wide range of threats from phishing sites to AI-crafted scam infrastructure. 

Guardio’s core value lies in its adaptive browser extension and mobile protection apps that scan for emerging cyber threats in real time. It uses AI-driven threat detection to identify malicious artifacts in websites and code generated by AI tools—a rising risk as “vibe-coding” platforms become more popular.  It also offers a “Critical Security Alerts” feature that intervenes during financial scams, warning users of suspicious behavior and helping prevent fraud. 

On the company side, Guardio secured $80 million in new funding in its latest round, led by ION Crossover Partners, with participation from Vintage Investment Partners, Union Tech Ventures, and Emerge.  The raise comes as the company claims triple its valuation since its previous $47M round in 2021.  Guardio reports consistent growth, noting over 100% ARR growth for three consecutive years.
