Directory Services Protector.

The industry’s most comprehensive Active Directory threat detection and response platform. See it live

Comprehensive Directory Threat Monitoring.

Business applications on-premises and in the cloud rely on Active Directory, making it a critical piece of your IT infrastructure. But securing Active Directory is difficult given its constant flux, sheer number of settings, and increasingly sophisticated threat landscape. Semperis Directory Services Protector (DSP) continuously monitors Active Directory for indicators of exposure, detects advanced attacks, and enables rapid response.

  • Stop attackers from gaining access to AD
  • Capture AD changes that bypass security logs
  • Automatically remediate malicious changes

Take back the keys to your kingdom.

Active Directory was not built to stand up against today’s threats. In our mobile-first, cloud-first world, any connected device can expose the heart of your IT infrastructure. In fact, you should assume that attackers are already lurking inside your network and just waiting for the opportune moment to strike. Defenders must anticipate their adversaries’ advances and be able to thwart attacks at every stage of the cyber kill chain. Meet Semperis DSP.

  • Accelerate Incident Response

    Speed up forensic analysis and get to the source of the attack. Translate unstructured AD change data into a human-readable format. Easily search, correlate, and undo changes at object and attribute levels. Drill down to any point in time to isolate compromised accounts and prevent future attacks.

Be in the know and in control.

Active Directory is difficult to secure given its constant flux, sheer number of settings, and the proliferation of powerful hacking and discovery tools. Semperis DSP puts AD security on autopilot with continuous threat monitoring, real-time alerts, and autonomous remediation capabilities. Managing by exception allows you to respond more effectively to security incidents as well as everyday operational mistakes.

Vulnerability Assessment

Continuously monitor for “indicators of exposure” that could result in security compromises to your AD. Leverage built-in threat intelligence from a community of security researchers.

Automated Remediation

Create audit notifications on changes to sensitive AD objects and attributes with the option to automatically undo select changes.

Tamperproof Tracking

Capture changes even if security logging is turned off, logs are deleted, agents are disabled or stop working, or changes are injected directly into AD.

Instant Find and Fix

Use Semperis DSP’s online database to find and fix unwanted AD object and attribute changes in two minutes or less.

Granular Rollback

Revert changes to individual attributes, group members, objects, and containers – and to any point in time, not just to a previous backup.

Forensic Analysis

Identify suspicious changes, isolate changes made by compromised accounts, and more. Use DSP data to support Digital Forensics and Incident Response (DFIR) operations to track down the sources and details of incidents.

SIEM Enrichment

Eliminate blind spots in your security incident and event management (SIEM) system with out-of-the-box integration.


Leverage robust Role-Based Access Control (RBAC) and a rich web user interface to give administrators view and restore capabilities for their specific scope of control.

Powerful Reporting

Gain insight into the operational, best practice, compliance, and security aspects of your AD using built-in reports created by AD experts. Create custom reports based on sophisticated LDAP and DSP database queries.

Real-time Notifications

Be alerted through email notifications as operational and security related changes happen in AD.

PowerShell Support

Use the DSP PowerShell module to automate processes and integrate DSP operations and management into existing toolset.

Uncover weaknesses in AD before attackers do.

Restore sight to your SIEM.

A growing number of attacks circumvent security auditing.

Unlike tracking tools that solely rely on security logs and agents on every domain controller, Semperis DSP monitors multiple data sources including the AD replication stream. The AD replication stream is the only reliable method of catching every change no matter how an attacker might attempt to cover their tracks. Semperis DSP forwards suspicious changes to your SIEM system with meaningful context, drastically reducing the burden on security analysts.

Semperis delivers security and business wins.

  • Better by design

    Leverages multiple data sources and a powerful database to overcome the fundamental shortcomings of traditional event-based change tracking and backup-based granular restore.

  • Easy to deploy and operate

    Comprehensive monitoring, vulnerability assessment, and remediation in a single console and from a holistic platform that scales to the very largest AD environments.

  • Non-intrusive

    Specifically architected to “play well” with Active Directory. Uses a unique approach to capture changes without compromising AD stability.

How can Semperis help me?


A hacker gains privileged access and disables native security logs. You discover the breach within 15 minutes and disable the hijacked account. You can’t see what was changed or potentially changed, so to be safe you restore Active Directory from backup. As a result, you lose several hours or even a day’s worth of legitimate changes, and users are locked out until those changes are redone.

With Semperis DSP, you can see what was changed during those 15 minutes and immediately undo any suspicious changes – eliminating the downtime and rework associated with a backup restore.

Configuration hardening

You perform an annual risk assessment looking for Active Directory vulnerabilities in hopes of stopping an attack. However, vulnerability assessment must be an ongoing, continuous process since AD is constantly changing and attackers fully understand how to exploit these vulnerabilities.

Semperis DSP continuously scans AD for risky configurations to identify weak links in your AD deployment. Based on this assessment, Semperis DSP provides a prioritized list of vulnerabilities and trends, as well as suggested corrective actions to reduce your AD attack surface.

Unexpected change to critical group

A user is added to a critical application group by something other than your user provisioning account. Semperis DSP allows you to define notification rules to automatically undo unexpected changes to users, groups, computers, containers, and OUs.

Password changed by mistake

A service desk operator resets the wrong user’s password and changes the CEO’s password by mistake.

An operator with delegated restore permissions in Semperis DSP can immediately undo the password reset so the CEO can keep their password (without having to share it with the service desk) and doesn’t have to update their password on all the devices they use to access email, files, dashboards, etc.

Scripting error

A script adds the wrong users to 100+ groups. With Semperis DSP, you can quickly isolate the mistaken additions and immediately undo them all with a few mouse clicks.

Accidental OU deletion

You delete an OU with 1,000 users across 10 sub-OUs. With Semperis DSP, you can restore an individual object or an entire hierarchy of 1,000+ objects with a single right-click operation.

Inadvertent DNS zone deletion

An administrator accidentally deletes a DNS zone, rendering an entire division non-functional. With Semperis DSP, you can undo changes to deleted or modified AD-integrated DNS zones as easily as user and computer objects.

Misconfigured Group Policy Object

A newly deployed Group Policy Object (GPO) or a GPO that was tampered with by an attacker breaks all production servers. With Semperis DSP you can track and compare changes and immediately roll back the GPO to the prior version.

With the addition of DSP Intelligence, Semperis further establishes DSP as the industry’s most comprehensive AD threat detection and response platform.

The continuous security assessment capabilities now available in DSP Intelligence address the skyrocketing proliferation of cyberattacks—including the infamous SolarWinds supply-chain attack and the Hafnium attack on Microsoft Exchange—that target identity systems, especially AD.
