Wallarm specializes in API security



Wallarm is a San Francisco-based cybersecurity company founded in 2013, specializing in advanced API and AI security solutions. With offices in Austin, TX, and backing from leading investors like Toba Capital ($55M Series C in July 2025), Y Combinator, and Partech, Wallarm achieved 134% Net Revenue Retention across enterprise customers in 2024-2025 and ranks on the Inc. 5000 list for rapid growth. Estimated annual revenue exceeds $33M, serving fintech, healthcare, e-commerce, SaaS, and manufacturing sectors while blocking over 15M attacks monthly.
The Wallarm API Security Platform delivers end-to-end protection for APIs, microservices, web applications, and agentic AI across multi-cloud, Kubernetes, and on-premises environments. Deployable in minutes via fully managed Security Edge (SaaS), Hybrid, or On-Premise models, it uses NGINX/Envoy-based filtering nodes that analyze traffic and send privacy-preserving metadata to ClickHouse-powered cloud analytics (US/EU instances) processing billions of requests daily.
Core capabilities include:
Automated API Discovery: Identifies shadow/orphan/zombie endpoints, PII exposure, and risk scores through passive traffic analysis—no agents required.
Runtime Protection: Machine learning blocks OWASP Top 10/API Top 10 attacks, BOLA, credential stuffing, L7 DoS, sophisticated bots, and GraphQL enumeration with near-zero latency; supports inline/out-of-band modes.
