About Impart Security
At a glance
Impart Security is a cybersecurity company specializing in Application Security, founded in 2021 and headquartered in San Francisco, United States. It has raised $19.7M in total funding, employs about 29 people, and is privately held.
Impart Security provides a runtime protection platform for applications, APIs, and large language models (LLMs). The company offers a programmable Web Application Firewall (WAF) that allows security teams to design, test, and deploy custom security controls with AI assistance. The platform integrates into CI/CD pipelines and provides transparent rule logic for policy customization. The company's technology addresses semantic-aware threats, including attacks targeting AI systems like RAG (Retrieval-Augmented Generation) implementations. Their WAF is designed to detect and block attacks at runtime rather than generating alerts, with capabilities for isolating untrusted content and simulating threats before production deployment. Impart Security was founded by former executives and engineers from Signal Sciences, Fastly, Edgecast, and Verizon who previously built multiple WAF products. The founding team includes Jonathan DiVincenzo (CEO), Marc Harrison (CTO), and Brian Joe (CPO), bringing experience in distributed systems, product development, and enterprise security solutions. The platform targets security teams that require granular control over application protection policies and need to adapt security controls to specific enterprise use cases. The company is backed by investors including Madrona, CRV, 8 Bit Capital, and Haystack.
