ammune.ai
ammune.ai (formerly L7 Defense) is a cybersecurity company that builds ammune™, a fully autonomous, AI-based platform for protecting APIs - and, increasingly, AI systems and data centers - from cyberattacks. Using unsupervised machine learning, ammune auto-discovers APIs and builds a tailored protection layer for each one inline from the first request, blocking dozens of attack types (bots, DDoS, business-logic abuse, injection) in real time without pre-training or rule-writing. The platform is platform-agnostic, running on-premises, in the cloud, in Kubernetes clusters, and offloaded onto DPUs such as NVIDIA BlueField-2, and it recently expanded toward offline, air-gapped protection for AI workloads.
SentinelOne
SentinelOne is an American cybersecurity company that builds the AI-powered Singularity Platform, autonomous software that detects, hunts, and responds to attacks across endpoints, cloud, identity, and data in real time. Founded in 2013 and headquartered in Mountain View, California, it pioneered machine-learning-driven endpoint protection that works without human intervention and now competes head-to-head with CrowdStrike and Microsoft in the enterprise security market. After the largest cybersecurity IPO in history in 2021, the company crossed $1 billion in annual recurring revenue in 2025.
Hakimo
Hakimo is a San Francisco-based AI security company founded by Stanford researchers Sam Joseph and Sagar Honnungar. The company builds autonomous AI agents that monitor physical security infrastructure - cameras, badge readers, access control systems - in real time, detecting threats and responding with automated talk-downs before incidents escalate. Serving over 400 properties across construction, automotive, self-storage, corporate offices, and higher education, Hakimo has raised $20.5 million in total funding and delivers a 60% reduction in security incidents for its customers.
