About Prompt Security

Prompt Security offers protection for both employee use of AI tools and the apps an organization builds. Prompt Security continuously tracks prompts per day in organizations of 500 to 1,000 employees.[4][5]

Prompt Security holds that securing agentic AI is fundamentally different from securing traditional software. Prompt Security states that agents act autonomously, call tools and reason over untrusted input, so prompt injection, identity and runtime behavior have to be governed in real time and not only at the perimeter.

Prompt Security provides a security skill suite for OpenClaw, NanoClaw and Hermes agents.[6]

Prompt Security provides a tool that tracks and analyzes OpenClaw deployments across an organization. Prompt Security provides a tool that tests and hardens a system prompt against dynamic LLM-based attacks.[4][9]

Prompt Security publishes news, research, tools and analysis for security teams responding to AI threats. Prompt Security describes an AI gateway as a centralized layer between an organization's users or applications and the AI models or services they call. An AI gateway, as Prompt Security describes it, lets security teams monitor, control and secure that traffic from one place instead of instrumenting every application separately.[4]

Prompt Security curates an interactive, continuously updated directory of 471 companies building security for agentic AI, organized across 14 functional categories. Both pure-play startups and dedicated AI-security lines from larger vendors are in scope for the Prompt Security directory. Entries in the Prompt Security directory are compiled from vendor websites, product documentation, funding announcements, public company registries and analyst coverage. Placement in the Prompt Security directory reflects publicly stated capabilities, not vendor marketing tiers. Category definitions and threat coverage in the Prompt Security directory are mapped against established, independent frameworks for AI and LLM security. The full dataset behind the Prompt Security directory is open and machine-readable.[2][4][5][6][9]
