Knostic vs Pillar Security

Knostic provides need-to-know access controls for enterprise AI assistants such as Microsoft Copilot, Glean, and Gemini. The platform discovers shadow AI usage, enforces knowledge-layer policies at request time, and produces audit logs that document who accessed what data through which AI system. Headquartered in Herndon, Virginia, Knostic was founded in 2023 and serves regulated industries that need to adopt LLMs without exposing sensitive internal data.

Pillar Security is a unified AI security platform that provides visibility, risk assessment, and protection across the entire AI lifecycle from development to runtime. The platform discovers AI assets including agents, models, prompts, and tools—even shadow AI—maps attack surfaces with RedGraph for agentic red teaming, enforces policies, monitors behavior, and applies adaptive guardrails to prevent data exfiltration and prompt injection. It generates compliance reports mapped to leading standards and integrates with code, AI, and data platforms. Targeted at enterprises adopting agentic AI, it addresses security gaps in autonomous software by combining threat intelligence with runtime controls, enabling safe AI deployment while operationalizing governance for regulated environments. SOC2 Type II compliant with RBAC and self-hosted deployment options.
