AI-Powered API Penetration Testing and Security

Equixly provides automated API security testing and continuous vulnerability detection, emphasizing AI-powered penetration testing that integrates directly into modern software development lifecycles. The platform mimics the methodologies of ethical hackers and blends reinforcement learning with advanced testing heuristics to identify a wide range of API weaknesses, from common logic flaws to complex zero-day vectors.

Its testing engine supports both gray-box and limited black-box approaches, simulating real-world attack scenarios to uncover authentication issues, OWASP Top 10 API risks, and business logic vulnerabilities. The platform additionally includes API security posture management, continuously monitoring configurations and access controls for misconfigurations and emerging risks.

Based in Florence, Italy and founded in 2022, Equixly initially raised €1.5 million in November 2023 from 360 Capital with participation from Nana Bianca and Stephen De Vries, co-founder and CEO of IriusRisk. In December 2025, Equixly raised a €10 million

Series A led by 33N Ventures and Alpha Intelligence Capital. JME Ventures, 360 Capital and the Fondazione Cassa di Risparmio di Firenze also participated.
