End-to-end security for ML models, AI apps, and the AI supply chain.

Protect AI secures the AI/ML lifecycle from model selection through deployment and runtime: model scanning for serialization attacks, AI red teaming, posture management, and runtime protection. It also stewards open-source tools like ModelScan. Acquired by Palo Alto Networks in 2025 and integrated into the Prisma AIRS platform.

AI security platform: model scanning, runtime defense, and automated red-teaming.

HiddenLayer's AISec Platform unifies AI supply-chain security, runtime detection and response, posture management, and automated red-teaming for generative, agentic, and predictive AI. Its Model Scanner inspects model files for malware and integrity issues, while AI Detection & Response monitors prompts and responses with deterministic classifiers.

Real-time guardrails against prompt injection and jailbreaks for AI apps.

Lakera Guard sits between users and LLMs as a low-latency security layer, detecting and blocking direct and indirect prompt injection, jailbreaks, and system-prompt extraction across 100+ languages. Its models are trained on adversarial data from Gandalf, Lakera's prompt-injection game. Acquired by Check Point in 2025.

Enterprise platform to discover, govern, and protect AI agents and applications.

An enterprise AI security platform that inventories every model, agent, MCP server, and data dependency across your stack, scans for misconfigurations and supply-chain risks, red-teams AI applications, and enforces runtime guardrails against prompt injection and rogue agent behavior. Founded in Tel Aviv in 2023, it counts UiPath, Best Buy, and Nielsen among its customers. Enterprise pricing via demo.
