  Lakera (Cisco)

  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 Cisco in 2025.

  AI insight: Its detection models train on adversarial prompts harvested from Gandalf, its viral prompt-injection game; acquired by Cisco in 2025.

  Lasso Security

  Lasso Security

  End-to-end GenAI security: shadow-AI discovery, red-teaming, and runtime guardrails.

  Lasso Security protects every LLM interaction across cloud and on-prem deployments, combining shadow-AI discovery, real-time threat detection, policy enforcement, and red-teaming with thousands of attack types. It deploys via gateway, API, or SDK to secure both internal LLM apps and employee use of third-party chatbots.

  AI insight: Lasso frames LLM security as a five-stage lifecycle (Discover, Assess, Test, Enforce, Protect) and sells it as one product, not add-ons.

  Pangea

  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 insight: Sells security as composable API services (AI Guard, Prompt Guard, audit log, redaction, authz), so you add guardrails with plain API calls.

  Prompt Security

  Prompt Security (SentinelOne)

  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.

  AI insight: SentinelOne acquired Prompt Security in 2025 (~$250M) to anchor its GenAI/agent-security line within the Singularity platform.

  Protect AI

  Protect AI (Palo Alto Networks)

  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 insight: Acquired by Palo Alto Networks in 2025 and folded into Prisma AIRS; stewards the open-source ModelScan and NB Defense tools.

  Snyk

  Snyk

  Developer security platform with DeepCode AI for SAST, SCA, and AI-generated fixes.

  Snyk finds and fixes vulnerabilities in code, open-source dependencies, containers, and IaC. Its Snyk Code SAST engine, DeepCode AI, combines symbolic and machine-learning analysis with inter-file data-flow tracing to detect issues and auto-generate fixes. Integrates into IDEs, the CLI, and CI.

  AI insight: Snyk Code is built on DeepCode AI, the symbolic+ML engine from its 2020 DeepCode buy, trained on millions of data-flow cases, not an LLM.
