What Pillar Security does
Pillar Security is a private AI security company that provides an end-to-end platform for discovering, governing, and securing AI agents and AI applications across their lifecycle. Its platform spans four modules: AI Discovery & Posture (cataloging agents, models, prompts, frameworks, tools, and MCP servers including shadow AI, with supply chain scanning), Red Teaming & Attack Surface Exposure (executing multi-turn adversarial attacks and mapping blast radius via the RedGraph tool), Runtime Guardrails (real-time monitoring of agentic behavior, sensitive data masking, and adaptive protection), and Governance & Compliance (translating policies into technical controls mapped to GDPR, EU AI Act, ISO 42001, and SOC 2). The company also co-developed the SAIL Framework and is a founding contributor to the Agent Control Standard (ACS) open specification.
Pillar serves a sales-led enterprise and AI-focused startup customer base, with named customers including Eleos (healthcare), Tavily (technology), Similarweb (technology), and AvidXchange (financial services), plus undisclosed Fortune 500 accounts. The company operates on a SaaS subscription model with per-seat or enterprise licensing, sold through direct field sales and demo-based qualification. Pillar has offices in Tel Aviv, Israel (primary headquarters) and Ontario, Canada; the Ontario entity was acquired by Scarlet Security & Risk Group (SSRG) in December 2025. The company raised $9 million in seed funding in April 2025 led by Shield Capital, with participation from Golden Ventures and Ground Up Ventures.

Pillar Security competitors and assessment
Company assessmentDirect peers
- Protect AI: Protect AI offers an AI/ML security platform covering model scanning, red teaming, and supply chain security. Most direct competitor to Pillar across the AI lifecycle, targeting the same CISO buyer with an overlapping discovery-to-runtime thesis.
- HiddenLayer: HiddenLayer provides AI security posture management and adversarial threat protection for ML models and applications. Closely comparable to Pillar in scope (posture, runtime, governance) and target buyer (enterprise security teams).
- Lakera: Lakera focuses on prompt injection and LLM/agent runtime protection (Gandalf, Red). Overlaps with Pillar's runtime guardrails and red teaming modules and competes for the same AI security budget, especially among AI-native startups.
- TrojAI: TrojAI builds AI security solutions for model and application protection, including trojan detection and red teaming. Listed alongside Pillar as a Wiz AI-APP integration partner, making it a direct functional peer in red teaming and prompt injection detection.
- Robust Intelligence: Robust Intelligence (acquired by Cisco) provided an AI firewall and model risk management platform covering testing and runtime enforcement. Closely comparable to Pillar's discovery, posture, and runtime guardrails, now operating within Cisco's broader security portfolio.
- Adversa AI: Adversa AI specializes in adversarial testing and red teaming for AI systems, including autonomous agents. Overlaps with Pillar's Red Teaming & Attack Surface Exposure module and competes for AI security evaluation budget.
Broad incumbents
- Wiz: Wiz is a leading cloud security platform that launched its AI-APP offering (March 2026) integrating Pillar, TrojAI, and Cloudflare. As a Wiz integration partner, Pillar is also exposed to Wiz as a potential competitive bundler of AI security capabilities into its CNAPP platform.
- Cloudflare: Cloudflare is a broad security and networking platform with growing AI security offerings (e.g., AI Gateway, bot/abuse mitigation). Co-listed with Pillar in Wiz's AI-APP and a credible incumbent that could absorb AI security workloads at the edge.
- Palo Alto Networks: Palo Alto Networks offers Prisma AIRS for AI runtime security and posture management across its broader security platform. Represents the platform-incumbent threat to standalone AI security vendors and competes for the same CISO budget.
- Microsoft: Microsoft ships Defender for AI, Azure AI Content Safety, and Purview AI Hub as integrated parts of its security and Azure stack. As the dominant enterprise platform vendor, Microsoft represents the most significant bundling risk to Pillar's standalone AI security GTM.
