Guardio Secures $80M in Funding - Security Startup News

A Growing Concern in the Digital Landscape

Contemporary internet usage is accompanied by a rising number of security challenges. The proliferation of AI-powered vibe-coding tools, along with the websites and applications they create, has unfortunately led to an increase in vulnerabilities and security gaps.

Guardio's Response to AI-Driven Threats

Cybersecurity firm Guardio is addressing a newly emerging market focused on identifying malicious code generated by artificial intelligence. The company reports that AI tools are now simplifying the process for malicious actors to construct phishing and scam websites, as well as the necessary infrastructure to operate them.

Guardio is now applying its expertise in developing browser extensions and applications that detect malicious and phishing sites to create a tool specifically designed to identify artifacts within code and websites built using these AI-driven vibe-coding platforms.

Partnership with Lovable and a Focus on Security

The company has already secured a significant partnership. Lovable recently announced a collaboration with Guardio to scan all websites hosted on its platform, proactively eliminating those that could potentially endanger users. This decision followed a report revealing substantial security weaknesses in several Lovable-built sites.

Michael Vainshtein, the startup’s CTO, emphasized a common trend: “Innovation and market share are prioritized, often with security being an afterthought. Few AI tool developers are actively collaborating with cybersecurity firms to ensure the content generated on their platforms is secure and utilized responsibly.”

Funding and Expansion

To support its growth initiatives, Guardio has successfully raised $80 million in a new funding round led by ION Crossover Partners. Existing investors, including Union Tech Ventures, Vintage Investment Partners, and Emerge, also participated in this funding.

Founded in 2018 by Vainshtein, CEO Amos Peled, and chief architect Daniel Sirota, Guardio has not publicly disclosed its current valuation. However, the company confirmed that its valuation has tripled since its previous funding round – a $47 million investment led by Tiger Global in 2021.

Despite this significant growth, Guardio does not currently classify itself as a “unicorn” company.

Evolution of Guardio’s Services

Initially, Guardio began as a browser extension designed to identify and alert users about malicious websites and data breaches. The company subsequently expanded its offerings to include phishing protection, and developed mobile applications providing identity management, spam filtering, and scam prevention.

Currently, Guardio boasts 500,000 paying users and reports achieving $100 million in annual recurring revenue this year.

New Visibility Features for Enhanced User Control

Guardio is introducing new features to provide users with greater insight into their publicly shared documents and identify any sensitive information exposed. These features will also notify users about accounts lacking multi-factor authentication.

The startup explains that these capabilities are inspired by enterprise-level Data Loss Prevention and SaaS Security Posture Management solutions.

“Individuals utilize a multitude of services, resulting in fragmented data and complex security settings,” Vainshtein stated. “We aim to equip consumers with the visibility into their accounts that enterprises currently possess, without requiring them to become security experts.”

The company is actively developing integrations with Outlook and Facebook to provide users with more detailed information regarding potential security risks associated with these platforms.

Future Plans and Investor Confidence

Peled indicated that the startup intends to incorporate some of these new visibility features into its free subscription plan next year.

Gilad Shany, founder and partner at ION Crossover, shared that the investment firm had been closely monitoring Guardio for several years. Despite Guardio not actively seeking funding, ION initiated discussions with the company last year.

“Our firm has a strong track record in both the cybersecurity and consumer markets, with numerous successful IPOs and exits. Guardio represents our first investment at the intersection of these two sectors – a team capable of leading cutting-edge cybersecurity product innovation while possessing a deep understanding of scaling a direct-to-consumer business,” Shany concluded.
