Securing the Agentic Workforce

COMPANY OVERVIEW

Pillar Security is an AI security company founded in 2023 and based in Tel Aviv, building security tooling purpose-built for organizations operating Artificial Intelligence systems. The company focuses on risks across the full AI lifecycle, from model development to deployment, and provides a unified platform that automates discovery, assessment, and governance of AI-related assets. Its system identifies and classifies machine learning models, datasets, APIs, agents, and dependencies, integrating directly with code repositories, cloud infrastructure, and data platforms to maintain up-to-date inventories and risk visibility.

In April 2025, Pillar Security raised a $9 million seed round, backed by Shield Capital, Golden Seeds Venture Fund, and Ground Up Ventures. In February 2025 the company received non-equity support from AWS and the CrowdStrike Falcon Fund. Pillar is SOC 2 Type II certified, named a Gartner Representative Vendor in the 2026 Market Guide for Guardian Agents, and recognized by SACR's Agentic Defense Platforms report and Frost & Sullivan's Competitive Strategy Leadership Award. Customers include Eleos, Tavily, SimilarWeb, AvidXchange, and additional Fortune 500 enterprises deploying AI at scale.

CORE FOCUS

Pillar's platform conducts multi-layered evaluations across privacy exposures, supply chain vulnerabilities, model manipulation risks, and infrastructure weaknesses. It supports both static and dynamic testing aligned with industry frameworks such as OWASP and MITRE ATT&CK. Runtime components provide adaptive defense, automatically adjusting controls in response to anomalous activity or simulated attack conditions.

The company's detection approach incorporates adversarial AI research and real-world incident data to maintain resilience against threats such as poisoned training data, compromised agents, malicious API calls, and cross-environment intrusions. Pillar positions itself as an end-to-end security layer for AI applications, enabling continuous monitoring, incident readiness, and compliance enforcement across distributed AI environments.
