Zilla Security (now Palo Alto Networks Identity Governance)

Zilla Security built a modern identity governance and administration (IGA) platform designed to replace the spreadsheet-driven, manual access review processes that plague most legacy IGA deployments. The platform automated access certification, discovered segregation-of-duties violations and orphaned accounts, and managed the full joiner-mover-leaver identity lifecycle with AI-driven recommendations, integrating with applications via APIs and robotic process automation to reach legacy systems without extensive custom integration work.

Founded in Boston in 2019, Zilla Security was acquired by Palo Alto Networks in 2024 and has since been rebranded as Idira, now operating as Palo Alto Networks’ identity governance product integrated with its broader identity security and privileged access management portfolio. The product maintains a single system of record for all entitlements with full change history, positioning itself as purpose-built for modern, hybrid enterprises rather than legacy, on-premises-first IGA tools.

Acquisition by Palo Alto Networks, one of the largest cybersecurity platform vendors, is a strong validation of Zilla’s modern IGA approach, and automating access reviews genuinely reduces both audit burden and access-related risk; as with any product now inside a much larger platform, its independent innovation trajectory has given way to Palo Alto Networks’ broader identity security roadmap.
