GitLab has appointed Chaim Mazal as Chief Information Security Officer, bringing in a security executive with experience across AI governance, adversarial defense, and enterprise security operations. Mazal will lead GitLab’s global security organization and oversee security for both the company and its DevSecOps platform.
Mazal most recently served as chief AI and security officer at Gigamon, where he led the company’s security and AI programs, including governance and responsible adoption. He previously held senior security leadership roles at Kandji and ActiveCampaign.
GitLab said Mazal’s experience will support its work around emerging AI-driven threats as software teams adopt agents across development workflows. CEO Bill Staples said developers need to find and fix vulnerabilities before code reaches production as agents move faster and exploitation timelines shrink.
Mazal has 15 years of security leadership experience and has worked across adversarial security and enterprise security program design. He also serves on the advisory boards of Cloudflare, Rapid7, Axonius, and Bugcrowd.
Before joining GitLab, Mazal had been a GitLab customer for more than eight years and served on the company’s advisory board. He said frontier models are changing software security, adding that GitLab has “a real opportunity to define what a world-class AI security program looks like for us and our customers.”
