GitLab announced the appointment of Chaim Mazal as Chief Information Security Officer, framing the role around defining what AI security looks like for the next generation of software development.
The DevSecOps platform's CISO effectively sets security posture for a meaningful slice of the world's software supply chain, and GitLab's own framing of the hire — AI security first — is a signal of where platform security leadership mandates are moving in 2026.
According to the release, Mazal heads GitLab's global security organization and oversees security for GitLab as both a company and a platform.
Mazal has 15 years of security leadership experience, and the release says his practitioner background covers enterprise security program design as well as adversarial security. The release says Mazal was most recently Chief AI and Security Officer at Gigamon, where he ran security and the company's AI program, including governance. He earlier held senior security leadership roles at ActiveCampaign and Kandji, among others, according to the company. The release said Mazal served on the advisory boards of Bugcrowd, Axonius, Rapid7 and Cloudflare at the time of the announcement. According to the release, Mazal had used GitLab as a customer for more than eight years before taking on the CISO role.
The company describes GitLab as an intelligent orchestration platform for DevSecOps that helps organizations reduce security and compliance risk and increase developer productivity.
