Mindgard

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.

Autonomous AI pentesting that finds and exploit-validates vulnerabilities continuously.

XBOW is an autonomous offensive security platform that runs AI-driven penetration tests against web applications, validating every finding through real exploitation rather than flagging unconfirmed scanner noise. Founded by Semmle founder and GitHub Copilot creator Oege de Moor, it runs continuously instead of as a point-in-time engagement. Customers include Moderna, Samsung SDS, and Tyler Technologies; it raised a $120M Series C at a $1B+ valuation in 2025.
