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.

Pros & cons

  • Gartner 2026 Guardian Agents vendor
  • Enterprise sales; no public pricing
