Cayosoft Unveils Free Real-Time Defender for Microsoft Hybrid Identity Environments

When it comes to enterprise identity infrastructure, few attack surfaces are as pervasive—and as persistently exposed—as Microsoft Active Directory (AD) and Entra ID. Cayosoft, a longtime player in this domain, is stepping up its defense game with Guardian Protector, a free, always-on identity threat detection and monitoring solution aimed squarely at the hybrid Microsoft ecosystem.

Breaking the “Point-in-Time” Barrier

Traditional security scanners for Microsoft environments have long relied on static snapshots—useful for compliance audits but powerless against real-time manipulation. Cayosoft’s new Guardian Protector changes that dynamic by offering continuous visibility and live threat detection across AD, Entra ID, Microsoft 365, Intune, Teams, and Exchange Online.

For administrators who’ve watched their visibility shrink as cloud sprawl expands, it’s a long-awaited shift. Guardian Protector continuously tracks privilege escalations, dormant account activations, and policy tampering as they happen, surfacing proactive alerts and remediation guidance without license limits or data caps.

“Active Directory and Entra ID are the backbone of business operations, and still one of the most under-protected attack surfaces,” said Robert Bobel, founder and CEO at Cayosoft. “For the first time, every organization, no matter the size, can get free, real-time protection against identity threats. No licenses. No quotas. Just continuous defense and real-time alerts.”

Hybrid Complexity Meets Shrinking Expertise

More than 90 percent of large enterprises still depend on AD, and most have extended their identity management footprint into Entra ID. Yet as veteran AD administrators retire, organizations face widening visibility gaps—and attackers are capitalizing on them.

“Identity has become the new security perimeter, and Microsoft hybrid environments are among the most targeted attack surfaces,” said Vickie Brown, Director of Public Sector at XMS Solutions. “By lowering cost and complexity, [Guardian Protector] enables faster adoption while giving agencies a practical way to strengthen resilience against ransomware, insider threats, and identity compromise—all while advancing Zero Trust mandates.”

Building a Global Defender Network

Cayosoft isn’t just releasing software—it’s attempting to cultivate an ecosystem. The launch comes alongside two new resources:

• The Cayosoft Guardian Reddit Community, a dedicated hub where IT pros and security engineers can share detections, discuss incidents, and exchange remediation strategies.

• The Cayosoft Threat Directory, a continuously updated feed of hybrid identity attack tactics, correlated with detection patterns that plug directly into Cayosoft’s monitoring capabilities.

Together, these tools aim to bridge the gap between technology and tribal knowledge—a critical factor in the defense of legacy-meets-cloud infrastructures.

“With Guardian Protector, we’re not just releasing another tool — we’re strengthening the global identity community,” said Dmitry Sotnikov, Chief Product Officer at Cayosoft. “By combining advanced capabilities with the new Reddit Community and Threat Directory, we’re giving practitioners both the technology and the shared intelligence to stay ahead of evolving threats.”

The Freemium Security Shift

The concept of a no-cost, full-visibility, hybrid identity security platform is a notable market disruption. Competing solutions often gate continuous monitoring behind enterprise-grade licenses, leaving smaller teams exposed. By removing financial friction, Cayosoft could democratize access to professional-grade hybrid identity protection—an especially timely move as ransomware crews increasingly target smaller organizations with unpatched or misconfigured AD environments.

Cayosoft’s broader Guardian platform already handles detection, monitoring, and full-forest recovery. Guardian Protector appears to be its Trojan horse: a free entry point designed to build trust and accelerate adoption across enterprises looking for resilience without red tape.

In an era where identity is the new perimeter, Cayosoft Guardian Protector might just redefine what “free security” actually means—continuous, community-backed, and uncompromisingly real-time.
