SYDNEY, Australia – 18 September 2025 – Cohesity and Semperis today announced a new product, Cohesity Identity Resilience, powered by Semperis, to defend enterprises’ critical Identity infrastructure, including Microsoft Active Directory assets, from cyberattacks. Now available for purchase from Cohesity, the solution is the strongest of its kind in the market, enabling companies to proactively harden defences, recover rapidly, and conduct comprehensive post-attack forensic investigations.

Active Directory is the central nervous system of most enterprise IT environments, managing authentication and access to critical systems, applications, and data. Active Directory’s crucial role within IT environments makes it a primary target for cybercriminals. When Active Directory is compromised, attackers can gain unrestricted access to IT resources, often resulting in ransomware infection, data theft, and prolonged business disruption.

Cohesity Identity Resilience supports ‘Active Directory’ protection and recovery across hybrid environments. The solution helps users protect and secure on-premises Active Directory and extends these safeguards to Microsoft Entra ID in the cloud. Organisations can protect and recover the source of authority for objects synchronised across their entire Active Directory and Entra ID identity landscape.

“Identity Security is one of the key battlegrounds of cyberattacks for enterprises and governments. They need solutions that combine prevention, resilience, and recovery without adding complexity to their existing cyber resilience strategy,” said Sanjay Poonen, chief executive officer, Cohesity. “Cohesity Identity Resilience delivers a modern, proven approach that helps organisations protect the foundation of their digital operations, so they can recover quickly from even the most critical attacks on identity infrastructures and remain cyber resilient. We’re excited to partner with Semperis on this effort.”

“Across the ANZ region, identity access is emerging as one of the fastest-growing threat vectors, as cyber criminals work relentlessly to exploit vulnerabilities in today’s complex IT environments. This makes protecting foundational identity systems like Active Directory absolutely critical,” said Peter Hanna, vice president of partners, Asia Pacific, Japan & Greater China, Cohesity. “With Cohesity Identity Resilience, we can now offer our partners and their customers a market defining solution that uniquely combines proactive protection, rapid recovery, and post-incident analysis.”

Cohesity Identity Resilience builds on Semperis’ proven expertise and technology in Active Directory protection and recovery, delivering automated, malware-free recovery capabilities that minimise downtime and ensure a clean, reliable path back to normal business operations. With Cohesity Identity Resilience, customers benefit from:

• Proactive Active Directory hardening – Provides the ability to scan on-prem or hybrid Active Directory environments for hundreds of indicators of exposure (IOEs), see risk scores, apply remediation guidance, and identify and prioritise attack paths that bad actors could use to reach critical privileged assets (Tier 0).
• Secure, immutable backups with capability for cyber vaulting – Enables consistent backup and recovery workflows while providing isolation of AD backups.
• Rapid and secure recovery – Restores Active Directory forests after a cyberattack or catastrophic failure, ensuring minimal downtime.
• Specialised identity forensics and incident response capabilities – Cleanses the system of attacker artifacts, ensuring Active Directory is restored to a trusted environment.
• Comprehensive post-breach analysis – Offers comprehensive post-attack forensic support, including rapid assessments within defined incident windows, and validation of Active Directory integrity before restoring production systems.

“Active Directory remains one of the most targeted assets in modern cyberattacks. Cohesity Identity Resilience, powered by Semperis, enables organisations to strengthen their resilience, ensuring they can withstand, respond to, and recover from identity-based threats with confidence,’ said Gerry Sillars, Semperis, Vice President Asia Pacific & Japan.

Cohesity Identity Resilience builds on the partnership between Cohesity and Semperis that began in 2024.

“Active Directory compromises often turn into prolonged business disruptions that are costly and difficult to contain,” said Scott Harrison, director, Hybrid Infrastructure Solutions, CDW. “With Cohesity Identity Resilience, powered by Semperis, we see a solution that directly addresses this gap—helping enterprises strengthen defences, recover quickly, and maintain confidence in their core identity systems. It’s the kind of capability our customers have been asking for, and it represents an important step forward in building true cyber resilience.”
