EBSCO has saved over 1,000 hours by using SpyCloud to check Active Directory credentials against fresh breach data and reset compromised passwords automatically.

Stay Ahead of Criminals with Early Breach Notification

For the first 18-24 months after a breach, criminals limit access to stolen data to a small group of trusted advisors. That period of time is the most lucrative for criminals, and the most dangerous for organizations whose users may have been exposed. By the time the breach trickles out to the deep and dark web where anyone can access it, the worst damage has been done.

With SpyCloud Active Directory Guardian, you can reset compromised passwords before criminals have a chance to use them against you. SpyCloud researchers use human intelligence and proprietary tradecraft to gain access to stolen data early in the breach timeline, giving you an advantage.

Reduce Your Team’s Workload Using Automation

Compromised Active Directory accounts put enterprises at risk—and create work for security and IT teams who need to investigate, respond, and remediate.

With Active Directory Guardian, you can:

  • Detect new credential exposures swiftly with regular updates from the SpyCloud research team
  • Reduce the time your team spends investigating and remediating potentially compromised accounts
  • Schedule scans to run automatically, with reports emailed to you
  • Reset exposed passwords automatically or with the click of a button
  • Install in minutes—without touching the domain controller or risking account lockouts

Detect and Reset Exposed Passwords Quickly

A criminal who finds your users’ Active Directory credentials through a third-party breach can easily log into your network or access services like remote file shares, Microsoft Exchange email servers, or SharePoint collaboration tools. To protect your enterprise, you need to take action quickly.

With SpyCloud Active Directory Guardian, you can automatically detect and reset compromised passwords that put your enterprise at risk, including:

  • Exact username and password matches that have been exposed in a third-party breach
  • “Fuzzy” variations of exposed passwords, such as changing Password to Password1!
  • Commonly-used passwords
  • Any previously-exposed password in the SpyCloud breach database

Easily Align with NIST Password Guidelines

Some NIST password guidelines can be satisfied using the built-in settings within directory services like Active Directory. Others require additional support—most notably, NIST’s guidance to check for and reset “commonly-used, expected, or compromised” passwords.

With SpyCloud Active Directory Guardian, you can dramatically reduce the time, cost, and resources required to align with NIST guidelines by identifying and resetting breached Active Directory passwords automatically.

Catch Password Reuse Across Work and Personal Accounts

Employee password reuse extends to personal accounts, creating a blind spot for security professionals. When an employee’s personal credentials are compromised in a data breach, it’s easy for a criminal to connect the dots and target that user’s Active Directory account.

Active Directory Guardian enables you to screen your AD accounts for any password that has ever appeared in SpyCloud’s database of billions of exposed passwords—whether or not your users were involved—and enables you to detect when employees select passwords that criminals are actively using in credential stuffing and password spraying attacks.
