Pillar Security Banks $9M for AI Security Guardrails

Shield Capital leads a $9 million seed-stage funding round for Israeli startup building technologies for AI security and privacy guardrails.

Pillar Security, a startup building security controls for enterprise AI deployments, has deposited $9 million in seed funding from Shield Capital.

The company, which has roots in Israel, said investors Golden Ventures and Ground Up Ventures also took equity positions.

Founded last October by Dor Sarig and Ziv Karliner, Pillar Security has ambitious plans to build technology to address security gaps in AI software. 

The company and its investors are betting that enterprises will spend heavily to replace traditional and deploy DevSecOps tools that may struggle to manage security, privacy and safety concerns in AI-powered applications.

Pillar Security said its software will provide security controls throughout the entire AI lifecycle, from integrating with existing code repositories and data infrastructures to mapping AI models, datasets, and frameworks.

The company said enterprise defenders can use the Pillar technology to AI models and their underlying infrastructure in real-time, and deploy guardrails tailored to each application’s risk profile. 

Pillar Security said its approach is designed to mitigate issues like evasion attacks, data poisoning, and intellectual property leakage. 

The Tel Aviv company said the money will be used to expand research and development and go-to-market activities.
