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.

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.

Discover, govern, and secure the AI agents across your organization.

Pillar Security is an end-to-end platform for securing enterprise AI — from discovering every AI agent, model, and integration in use to red-teaming them and enforcing runtime guardrails. It maps the AI supply chain across code, SaaS, and endpoints, then layers on governance, data-privacy controls, and compliance mapping. It targets AI-specific risks such as prompt injection, jailbreaks, and data poisoning.
