Cybersecurity startup Guardio has successfully closed an $80 million institutional funding round led by ION Crossover Partners. This significant investment will accelerate Guardio's mission to combat a rapidly emerging threat: malicious code and sophisticated phishing sites generated with the help of artificial intelligence (AI) tools.
The proliferation of AI-powered development tools, often referred to as "vibe coding tools," has inadvertently created new security vulnerabilities and blind spots across the internet. Guardio's research indicates that these advanced AI capabilities are making it easier than ever for malicious actors to create convincing scam and phishing websites, along with the underlying infrastructure to operate them.
Leveraging its extensive experience in developing browser extensions and applications that detect malicious and phishing sites, Guardio is now building a specialized tool designed to identify nefarious artifacts within code and websites produced using these AI-driven development methods. This proactive approach has already garnered significant interest, with Guardio recently partnering with Lovable, a startup specializing in AI-powered "vibe coding" platforms. The collaboration involves Guardio scanning all websites created on Lovable's platform to identify and eliminate potential threats to users, a move prompted by a report highlighting significant security vulnerabilities in several Lovable-built sites.
“Everyone is racing for innovation and market capture. But security is kind of an afterthought. And not many AI tools are partnering with any cybersecurity company to make sure that content generated on their platform is secured and used for good,” Michael Vainshtein, Guardio’s CTO, told TechCrunch.
The $80 million funding round, spearheaded by ION Crossover Partners, also saw participation from existing investors Union Tech Ventures, Vintage Investment Partners, and Emerge. While Guardio, founded in 2018 by Vainshtein, CEO Amos Peled, and Chief Architect Daniel Sirota, did not disclose its exact valuation, the company confirmed that its valuation has tripled since its previous $47 million fundraise in 2021, which was led by Tiger Global. Despite this rapid growth, Guardio stated it does not yet consider itself a "unicorn" company.
Guardio initially launched as a browser extension, providing users with alerts about malicious websites and data leaks. Over time, its offerings have expanded to include comprehensive phishing protection and mobile applications that provide identity management, spam filtering, and scam protection. The company now boasts 500,000 paying users and reported reaching $100 million in annual recurring revenue (ARR) this year.
Further enhancing its suite of services, Guardio is introducing new visibility features. These tools will inform users about publicly shared documents, highlight sensitive information exposure, and flag accounts lacking multi-factor authentication (MFA). Guardio notes that these features are inspired by enterprise-grade Data Loss Prevention (DLP) and SaaS Security Posture Management (SSPM) products.
“We use so many services, and our data is so fragmented with so many security settings to deal with. We feel every consumer is an enterprise in itself,” Vainshtein explained. “While we don’t want them to become security officers of their accounts, we want to offer capabilities of visibility into their accounts that enterprises have.”
The startup is also actively developing integrations with platforms like Outlook and Facebook to provide users with more detailed insights into potential security risks associated with these accounts. CEO Amos Peled added that some of these advanced visibility features are planned for inclusion in Guardio's free subscription plan next year.
Gilad Shany, founder and partner at ION Crossover, revealed that his firm had been tracking Guardio for several years. Even though Guardio was not actively seeking new funding, ION initiated discussions with the company last year. Shany commented,
“We have been investors in both the cyber and consumer markets, and have had multiple successful IPOs and exits. Guardio is the first company we invest in at the intersection of these two markets — having a team that can lead best-in-class cyber product innovation, while having intimate knowledge about how to scale a direct-to-consumer business.”
