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.

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.

API-based security guardrails for AI apps: prompt injection, PII redaction, and access control.

Pangea provides composable, API-first security services for AI applications. AI Guard and Prompt Guard defend against prompt injection, sensitive-data disclosure, and malicious content, alongside AI access control and visibility products. Pay-as-you-go with a free monthly balance, integrable via LiteLLM and Portkey.

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.
