Wallarm: $55 Million Series C Raised For API Security Platform

By Amit Chowdhry • Jul 31, 2025

Wallarm, a leader in API and AI security, has secured $55 million in a Series C investment round led by Toba Capital. This funding will allow Wallarm to scale operations and enhance its offerings for API protection in the evolving AI landscape.

As AI changes the threat landscape, attackers can exploit vulnerabilities more rapidly and target a wider array of APIs. Traditional security tools are insufficient for these challenges, making real-time blocking essential—an area where Wallarm excels.

Last year, Wallarm reported record growth with a 134% net revenue retention rate among enterprise accounts across various sectors. This growth is fueled by rapid innovation, including the recent introduction of agentic AI protection, which defends against AI-specific attacks.

Recent highlights include:

– Key strategic hires: Morgan Jay (President and CRO), Michelle Gerson (VP of Marketing), and Greg Deisher (CFO).

– Launch of agentic AI protection capabilities to monitor and block AI-driven attacks.

– Introduction of the first Penetration Testing Service for Agentic AI Systems.

– Release of the world’s first API Honeypot Report, providing insights into API attack trends.

– Driven by AI expansion, Wallarm achieved significant growth in 2024, maintaining nearly zero churn.
