Introducing Guardian Protector
Free Real-Time Hybrid Identity Threat Detection, Change Monitoring, and Alerting
Identity attacks do not wait. So why should you?
Every second counts when an attacker escalates privileges, reactivates dormant accounts, or quietly rewrites Group Policy. By the time legacy tools finish ingesting logs or snapshots, the compromise is already spreading through your environment.
This is the visibility gap that has plagued Microsoft Identity for two decades. And this is the gap Cayosoft Guardian Protector closes.
Launched recently, Guardian Protector is the first free solution that delivers unlimited, real-time threat detection and continuous change monitoring across Active Directory, Entra ID, Microsoft 365, Intune, Teams, and Exchange Online.
Guardian Protector Main Dashboard
Superior Real‑Time Detection: Outpacing Legacy Tools
In the face of relentless identity attacks, many organizations remain vulnerable, relying on outdated approaches that cannot keep pace:
- SIEMS ingesting logs with critical delays
- Point-and-time scans that give us a false sense of security
- Audit reports arriving weeks after the breach
By the time these legacy tools finally surface an anomaly, attackers have already escalated privileges, moved laterally, or firmly established persistence within your environment. The damage is often already done, and the business is suffering.
Guardian Protector rewrites this narrative. It delivers instant visibility into the identity-layer risks that attackers exploit, catching what you currently miss:
- Privilege Escalation
- Dormant Account Reactivations
- Group Policy Object Tampering
- Unauthorized deletions
- Policy Misconfigurations
This is not just faster detection; it’s a fundamental shift. Guardian Protector actively surfaces Indicators of Exposure (IOEs), Indicators of Compromise (IOCs), and Indicators of Attack (IOAs) in true real-time—a level of immediate insight that legacy tools cannot deliver.

Unrivaled Continuous Monitoring For Hybrid Identity
In today’s complex landscape, hybrid identity isn’t just a strategy, it’s a critical reality. The tightly intertwined nature of Active Directory and Entra ID, combined with the constantly expanding attack surface of M365, Intune, Teams, and Exchange Online, demands a new level of vigilance.
Guardian Protector eradicates the hidden risks within this intricate environment, delivering a single-pane-of-glass view into every critical change, every impacted object, and every second that matters.
Guardian Protector Live Change History
This means IT admins gain the comprehensive visibility they’ve lacked; compliance officers secure the irrefutable evidence required for audits, and security responders are empowered to act decisively, preventing minor issues from escalating into critical breaches that threaten business continuity.
Introducing The Guardian Threat Directory
While threat detection is paramount, actual security effectiveness hinges on rapid, informed response. Identifying an alert is merely the first step; understanding its implications and executing precise remediation is the real challenge.
That’s why we are proud to launch the Guardian Threat Directory alongside Guardian Protector. This essential resource empowers your security teams to move beyond mere alerts, transforming them into actionable intelligence.
Eliminating the need to sift through fragmented blogs or outdated whitepapers, The Guardian Threat Directory serves as a centralized, authoritative knowledge hub. It’s purpose-built for the exact threats administrators encounter daily across Active Directory, Entra ID, M365, and Intune.
Starting with critical misconfigurations like Unconstrained Delegation, Shadow Admins, and Entra Application Abuse, the library is a living resource. It expands weekly to incorporate new threats and evolving attack techniques, ensuring your defenses are always informed and up to date.
A Community Built For Admins
While cutting-edge security tools are essential, true cyber reliance is forged through shared knowledge and collaborative problem-solving. Security admins, on the front lines, need a dedicated space to ask candid questions, exchange detection insights, and share practical solutions that deliver real‑world impact.
That is why we are excited to launch the Guardian Community on Reddit, an open forum for collective expertise.

Why Guardian Protector Matters Now
The timing could not be more critical. Enterprises are facing the perfect storm.
- Veteran AD experts are retiring, leaving IT teams stretched thin
- Hybrid identity is expanding faster than most teams can keep up
- Attackers are exploiting configuration drift, delegation risks, and shadow admins at an unprecedented scale
Traditional tools are not built for this moment. They are too slow, too expensive, too incomplete, and give a false sense of security.
Guardian Protector was built for this moment:
- Real-time detection instead of delayed review
- Continuous monitoring instead of point-in-time snapshots
- Unlimited coverage instead of quotas and caps
- Knowledge and community alongside the tool itself
