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.

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.

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.

Runtime security for enterprise GenAI: shadow-AI visibility, data-leak and prompt-injection defense.

Prompt Security secures both employee use of GenAI tools and homegrown LLM applications, giving organizations visibility into shadow AI, blocking sensitive-data leakage, and preventing prompt injection in real time. Acquired by SentinelOne in 2025 and integrated into its Singularity platform.
