Unified AI security platform where offense and defense work as one system across the AI lifecycle: discovery and posture (AI-SPM cataloging models, tools, MCP servers, coding agents), a first-class Gartner-recognized red-teaming pillar (RedGraph offensive agentic testing, tool-use and black-box red teaming), runtime guardrails over agentic tool calls and permissions, and governance and compliance. A red-team finding becomes a policy becomes a retest, so protection compounds. Tops the AI-agent-security cluster on the strength of its offensive-testing loop.

Pillar Security is a unified AI security platform that secures the entire AI lifecycle from development to deployment, built on the conviction that securing AI agents takes offense and defense working as one system rather than a stack of point tools. It has four connected pillars. AI Discovery and Posture uses agentless integrations with code repos, data platforms, AI/ML frameworks, IdPs, and endpoints to auto-discover and catalog every AI asset (models, datasets, prompts, tools, MCP servers, coding agents, meta prompts), detect shadow AI, map dependencies, and run static and dynamic AI Security Posture Management across assets and their interconnections. Red Teaming and Attack Surface Exposure is its standout: RedGraph offensive agentic testing (recognized by Gartner), red teaming for tool use that models how chained tool and API calls can be weaponized (revealing vulnerabilities that prompt-based testing cannot), and black-box target-based red teaming where adversarial agents stress-test any accessible AI application with just a URL and credentials. Runtime Guardrails track every tool invocation, decision pattern, and permission across agentic workflows, log every interaction with metadata for audits and threat hunting, and catch issues like an agent inheriting broad permissions from its maker's identity and operating outside its intended boundary. Governance and Compliance enforce AI policies, translate them into technical controls (approved models, licensing, data sovereignty), validate third-party AI before it touches internal data, and generate audit-ready reports. Business context connects all four so intelligence compounds: a red-team finding becomes a policy, the policy becomes a retest that proves it fixed, and runtime telemetry flows back into the asset map and the next round of attack simulations. This closed offense-defense loop is what distinguishes Pillar from the agent-native governance platforms and the model-security incumbents in the same cluster.

What is public

The four platform pillars are public (discovery and posture, red teaming, runtime guardrails, governance and compliance) and the SAIL Framework is published; no dollar amounts are disclosed.

Variable cost rationale

Cost scales with the scope of AI assets, agents, and applications secured across the AI lifecycle, growing as an organization's AI footprint and number of production agents expand.
