| Description | HiddenLayer is an enterprise security platform for AI and machine learning that scans model files in formats like pickle, ONNX, and safetensors to detect backdoors, malicious deserialization, and tampering before deployment. It also provides AI runtime detection and response along with automated adversarial red-teaming across predictive, generative, and agentic systems. It targets enterprises and regulated industries securing their ML pipelines, with model-file scanning as its main differentiator. | Pillar Security provides AI security posture management with discovery across models, MCP servers, and coding agents, along with agentic red-teaming and adaptive runtime guardrails against jailbreaks and prompt injection. It also offers governance and compliance reporting, drawing on a proprietary AI-attack threat-intelligence feed. The platform targets enterprises deploying LLM applications and autonomous AI agents. |
