Hybrid Active Directory Recovery and Monitoring Software

Avoid Costly Hybrid AD Outages from Cyber Threats or Mistakes – In a Single Solution

Your Active Directory (AD) or Microsoft Entra ID (formerly Azure Active Directory) contain vital user identities that are crucial to ensuring your business operates without interruption. Whether from malicious actions, like cyberattacks and malware, or mistakes, like accidental deletions and misconfigurations, corruption of your Active Directory can stop your business in its tracks and cause costly outages that can last hours, days, or even weeks.

Why Cayosoft Guardian

Cayosoft Guardian was designed to reduce the complexity of hybrid Active Directory security, by combining threat detection, monitoring, and recovery into one comprehensive solution. Cayosoft Guardian continuously monitors directories and services, allowing you to isolate suspect changes and instantly recover unwanted changes made to both objects and settings. This is done across on-premises AD, hybrid AD, Entra ID, Office 365, Microsoft Teams, and Exchange Online, all from Cayosoft Guardian’s single, unified console.

Protect Vital Infrastructure

Active Directory is used by 90% of organizations worldwide, making it a prime target for cyberattacks.

Stop Attackers In Their Tracks

Discover and eliminate hybrid AD vulnerabilities. Identify and revert malicious changes before exploited.

Keep Business Running

Avoid or minimize the impact of costly ransomware attacks and AD outages. Ensure business continuity.

Features & Benefits

  • Recover Instantly

  • Instant AD Object and Attribute Recovery

    Instant object and attribute recovery allows administrators to rapidly recover from mistakes or malicious changes. Using granular change history, quickly find and fix unwanted changes, including changes to group memberships, group policy objects (GPOs), account settings, Microsoft licensing, Microsoft Teams memberships, and accidental AD object deletions. Cayosoft Guardian’s instant Active Directory recovery software enables you to recover fast and eliminate costly downtime caused by AD outages, without wasting time from the lengthy operations legacy file-based AD recovery tools require.

    Benefits:

    • Resolves outages fast, vastly reducing all associated costs
    • Easily identify & instantly reverse unwanted changes
    • Save lost productivity from common AD object deletions — keep operations running smoothly

  • Monitor for Changes

  • Continuous Change Monitoring and Alerting

How Cayosoft Compares

Continuous Monitoring of Active Directory

Instant Recovery of Active Directory

  • MANUAL PROCESS

  • Time-consuming and tedious process of searching through numerous native event logs and security settings. This results in the inability to see changes across entire hybrid AD environment, leading to security breaches, compliance failures, downtime, and costly service outages.

  • COMPETITORS

  • Traditional Active Directory monitoring tools and tools to monitor critical changes use file-based backups that need mounted or out-of-date snapshots. This leaves companies open to cyber risk and potentially business-crippling security breaches due to increased complexity and visibility issues across hybrid AD environments.

  • CAYOSOFT

  • Unified monitoring across on-premises Active Directory, Entra ID, hybrid AD, and Microsoft Office 365 environments. Change history repository keeps continuous, real-time backups enabling granular rollback of unwanted changes. Cayosoft Guardian was designed to simplify AD security and hybrid AD monitoring.

Instant Recovery of Active Directory

  • MANUAL PROCESS

  • Native backup and restore tools, like recycle bins, do not recover attributes and settings making them unsuitable for full object-level backups and attribute-level restorations. This time-consuming and tedious process can lead to extended downtime and expensive outages.

  • COMPETITORS

  • Legacy AD backup and recovery tools were designed only for on-premises Active Directory, requiring additional products and multiple consoles to recover across hybrid and cloud. Increased costs and inability to recover across hybrid AD environments leads to complex, error-prone processes and delayed recovery times.

  • CAYOSOFT

  • Instantly recover AD and Entra ID objects, attributes, and settings across on-premises AD, Entra ID, hybrid AD, and Office 365, with just a few clicks. With its single console, Cayosoft Guardian reduces the complexity of hybrid AD recovery and gets you back to business faster.

On-Premises Active Directory (AD):

  • Contact, group, user, and computer objects and attributes
  • Group memberships, group policy objects (GPOs) and GPO settings, privileged groups, organizational units (OUs), and Conditional Access policies (CAPs)
  • On-premises Exchange settings and policies

Microsoft Entra ID (formerly Azure AD):

  • Users, groups, and guests
  • Roles, group memberships, administrative units, and Conditional Access policies

Office 365:

  • Exchange Online and Microsoft Teams settings and policies

And more! For additional information or questions including full capabilities of Cayosoft Guardian, contact us.

Yes, Cayosoft Guardian delivers continuous AD monitoring and real-time alerts across hybrid Active Directory environments to changes, like AD users and groups, Entra ID roles, privileged AD groups, and Microsoft Teams settings. Cayosoft Guardian’s alert query also provides a simple way for you to create custom notifications to admins through Microsoft Teams and/or email.

Yes, Cayosoft Guardian will restore hard-deleted or permanently deleted AD objects. Since the objects are no longer present in Active Directory or Entra ID, Cayosoft Guardian will recreate the object using the details stored in its database.

Note: While Guardian recreates deleted objects, some links to those objects are not restored and may need to be manually assigned. For additional information or questions about how Cayosoft Guardian recovers deleted AD objects, reach out to us.

Cayosoft Guardian requires Windows Server 2016, Windows Server 2019, or Windows Server 2022.

Unlike traditional Active Directory (AD) backup software, like bare-metal backups, system state backups, full backups, or incremental backups, Cayosoft Guardian continuously backs up your Active Directory and Entra ID in real time, allowing you to quickly and easily revert changes to any point in time. This not only reduces storage space required but eliminates the risk of reintroduction of ransomware, reinfection, and additional corruption that can occur with some legacy Windows server backup tools.

Cayosoft Guardian does not recover on-premises domain controllers, but Cayosoft Guardian Forest Recovery does. Learn more about Cayosoft Guardian Forest Recovery, including all the features of Cayosoft Guardian plus domain controller recovery and forest recovery.
