Cayosoft Launches Guardian Protector, the First Free, Always-On Threat Detection for Active Directory and Entra ID

Cayosoft today introduces Cayosoft Guardian Protector, the industry’s only free, always-on solution that delivers real-time threat detection, proactive alerts, resolution guidance, and change history for complex Microsoft hybrid identity environments. Unlike other free solutions that offer point-in-time scans without alerts, Cayosoft Guardian Protector offers administrators and security teams continuous, real-time visibility and control across Active Directory (AD), Entra ID, Microsoft 365, Microsoft Teams, Microsoft Intune, and Microsoft Exchange Online.

More than 90% of large enterprises run Microsoft Active Directory and Entra ID, making them prime targets for ransomware and insider attacks. As seasoned AD engineers retire, IT teams are left with fewer resources to monitor the growing complexity. Meanwhile, the attack surface keeps expanding into Teams, Intune, and Exchange Online, creating blind spots attackers exploit. Most tools can’t keep up, offering partial visibility, delayed alerts, or costly licenses. Cayosoft Guardian Protector closes that gap.

Alongside Guardian Protector, Cayosoft is also introducing two powerful new resources to help the IT and security community stay ahead of attackers. The Cayosoft Guardian Reddit Community gives admins, security architects, and engineers a dedicated forum to collaborate, share expertise, and solve problems together. The Cayosoft Threat Directory delivers continuously updated intelligence on hybrid identity attack techniques and detection patterns. 

Together with Guardian Protector, these resources create a more powerful, comprehensive defense, blending real-time detection with community expertise and actionable intelligence. IT and security teams gain not only the tools to stop threats as they happen, but also the shared knowledge and foresight to stay ahead of whatever comes next.

Cayosoft Guardian Protector key benefits and features include:

  • Spot Threats Instantly. Detect risky, suspect changes as they happen with real-time detection and alerts: privilege escalations, dormant account activations, Group Policy tampering, and more.
  • See Every Change. Continuous Monitoring across AD, Entra ID, Intune, Teams, and Exchange Online gives unprecedented visibility of every change, resulting in fewer blind spots, faster investigations, and more substantial alignment of compliance across your identity infrastructure. 
  • Unlimited Coverage. Monitor every change of every identity object, every second without caps or license restrictions.
