Pillar Security Named as a 2026 Gartner® Cool Vendor in AI Software Security

A milestone that reflects our leadership in securing agents in the real world.

Today we are excited to share that Gartner recognized Pillar Security in its report Coolest Vendor Innovations in AI Software Security 2026, highlighting Pillar's RedGraph approach to offensive agentic AI security testing, our dynamic runtime guardrails, and the SAIL Framework. For us, the recognition validates a conviction we've built the company on: securing AI agents takes offense and defense working as one system, not a stack of point tools.

The Fastest-Growing Attack Surface in Software

Enterprises are moving AI agents into production faster than they can secure them, and attackers rarely need one big exploit to take advantage. Every permission an enterprise grants an agent - credentials, tool access, a route into production systems - doubles as an entry point for an attacker who learns to steer it.

The spending data tells the same story. Gartner forecasts worldwide AI cybersecurity spending to nearly double in 2026 - from $25.9 billion to $51.3 billion - and to reach $86 billion by 2027. The skills haven't kept pace with the spend: just 14% of software engineering teams surveyed have advanced skills in AI security or platform engineering, with about one-third starting to build basic proficiency in these skills.

That gap shows up for security teams in three places at once: seeing which AI systems are actually running and everything they connect to, proving those systems hold up under attack, and containing agents at runtime, where they act irreversibly at machine speed.

Pillar's Approach to Agentic AI Security

Pillar addresses these challenges with a unified platform where business context connects discovery, testing, and protection - closing the detection-to-mitigation loop, so security intelligence compounds across the entire AI lifecycle, for every AI agent an enterprise builds or buys.

The loop starts with visibility. Pillar maps every AI asset (agents, models, prompts, MCP tools, skills, datasets, configurations, and more) from source code, endpoints, and CI/CD into a live AI-BOM, and risk-scores each asset and its supply chain in business context (AI-SPM). That inventory feeds our Red Teaming engine (RedGraph), an autonomous adversarial agent that graphs the attack surface and runs multi-step, dynamic attack scenarios - chaining tool calls and performing reconnaissance the way a real attacker would - returning replayable and recordable evidence in minutes.

What RedGraph (Pillar’s Red Teaming) learns doesn't stay in a report - it drives the Pillar flywheel. Validated findings feed straight into the guardrails, calibrating enforcement at the application layer and on the endpoint, while runtime telemetry flows back into the asset map and the next round of attack simulations. A red-team finding becomes a policy, the policy becomes a retest that proves it's fixed. Each turn makes protection sharper - and generates audit-ready evidence for compliance and security teams along the way.

The Trust Behind The Technology

This recognition also belongs to the customers who trusted us - from Fortune 500 brands to innovative healthcare, commerce and tech companies - who put Pillar in front of their production agents and pushed the platform to earn its place there. 

Earning that trust has never been harder. We read this milestone as a reminder of the responsibility we carry: helping organizations move forward with AI agents, backed by the security their customers and stakeholders expect.
