Apex (Apex Security)
Apex Security was an AI security startup founded in 2023 in Tel Aviv by Matan Derman (CEO) and Tomer Avni (CPO), backed by Sequoia Capital, Index Ventures and angel investors including Sam Altman. Its platform gave enterprises visibility into generative-AI and LLM usage — public tools like ChatGPT and Gemini, Microsoft Copilot, and in-house AI applications — then let them define policy, detect violations and shadow AI, and respond to attacks across the AI attack surface. Tenable announced its intent to acquire Apex on 2025-05-29 and closed the acquisition in June 2025 for approximately $47.8M; the technology was folded into the Tenable One exposure management platform and now ships as Tenable One AI Exposure. Apex no longer operates as an independent company: the apexhq.ai domain has lapsed and was re-registered by an unrelated party on 2026-05-13, and now serves a Namecheap parking page. There is no Apex developer portal, documentation, or public API surface to catalog.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Apex (Apex Security) is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Apex (Apex Security) scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Properties that don't map to a standard resource type
Apex (Apex Security) is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
