Pillar Security has announced it has raised $9 million in Seed funding, which will support expanding Pillar’s R&D and go-to-market efforts.

The round was led by Shield Capital, joined by Golden Ventures, Ground Up Ventures and other strategic angel investors. As organisations rapidly build and deploy AI-driven software systems, traditional cybersecurity tools and processes are struggling to keep pace, creating critical protection gaps.

A recent Deloitte survey of 1,200 cybersecurity leaders identified major AI-specific risk areas – including evasion attacks, data poisoning, data privacy, and intellectual property leakage, with 77% of respondents expressing significant concern about these threats.

Moreover, two in five organisations have already experienced an AI-related security or privacy incident, one in four of which were malicious. The need for a purpose-built AI security solution has never been more urgent.

Pillar Security believes it addresses this need head-on, providing an end-to-end security platform specifically designed for AI-integrated software systems.

“AI is fundamentally changing the way we build software — it doesn’t just add another step to traditional processes; it introduces an entirely new lifecycle,” said Dor Sarig, CEO & Co-Founder at Pillar Security. “We are entering the intelligence age, where software has gained agency and data itself has become executable.

“Pillar’s technology, backed by real-world AI threat intelligence, is built with this understanding, delivering a new class of protection designed explicitly for AI-related security risks.

“We are redefining application security to match the agentic and autonomous software of the Intelligence Age. This funding accelerates our mission to set new AI security benchmarks, empowering organisations to innovate securely and confidently, while uniting AI teams and security teams around a common language and toolset.”
