As businesses continue to expand their digital footprints across on-prem, hybrid, and cloud environments, Microsoft Active Directory (AD) and Entra ID (formerly Azure AD) have become essential tools for managing identity and access. These systems form the backbone of authentication and authorization—granting or denying access to everything from internal applications and SaaS tools to entire production environments.
But with great power comes great responsibility—and risk.
AD and Entra ID aren’t just user directories. Together, they act as the gatekeepers of your enterprise’s digital kingdom. Any misstep, whether it’s a weak password, misconfiguration, or forgotten account, can be exploited by attackers to gain access, escalate privileges, and disrupt business operations. Protecting these critical systems isn’t just IT hygiene—it’s a cybersecurity imperative.
AD + Entra ID: A Unified Identity Strategy with Unified Risk
Active Directory has long been the industry standard for on-premises identity management, while Entra ID extends those capabilities to the cloud—powering secure access to Microsoft 365, Azure services, and thousands of third-party applications. Many businesses operate in a hybrid identity model, where AD and Entra ID work in tandem to manage user identities across different environments.
But this interconnectedness also means that a compromise in one can impact the other.
Whether you’re syncing identities using Azure AD Connect, managing access with Conditional Access Policies, or leveraging single sign-on (SSO) across platforms, protecting both environments equally is vital. A breach in AD can easily cascade into Entra ID, and vice versa.
Four Key Considerations for Keeping Active Directory and Entra ID Secure
AD and Entra ID are constantly evolving - users are added or removed, permissions change, and policies are updated. Frequent, automated backups are essential to capture this dynamic environment.
While Active Directory allows for some object recovery via tombstoning, it’s not enough. And Entra ID, being cloud-native, doesn’t offer the same level of native backup and recovery tools—making third-party protection even more critical.
A Backup as a Service (BaaS) solution optimized for hybrid environments helps:
You can cobble together scripts and open-source tools to protect AD or Entra ID separately—but should you?
Homegrown solutions often fall short when trying to orchestrate protection across both environments. They create silos, increase complexity, and require constant upkeep. Instead, businesses should consider a centralized, SaaS-based data protection solution designed specifically to handle both AD and Entra ID with:
The goal isn’t just protection—it’s resilience, across your entire identity estate.
A finely tuned directory structure in Active Directory or Entra ID often reflects years of careful planning. Organizational Units (OUs), group policies, role-based access controls, and security groups are meticulously defined.
Losing or corrupting this configuration can result in:
With a dedicated data protection solution, administrators can:
And this isn’t just about AD—Entra ID also benefits from granular rollback, especially when dealing with complex cloud-based role assignments, app registrations, and access policies.
Because AD and Entra ID are central to access, they’re also central targets for ransomware. Attackers exploit these systems to gain control, escalate privileges, and spread laterally across environments—often undetected.
A breach in AD can open the door to cloud environments via synced identities in Entra ID. Similarly, a compromise in Entra ID could expose cloud-first applications and user credentials synced back to on-prem.
Effective protection includes:
Organizations need to view ransomware defence holistically—not just for endpoint or storage protection, but as a key component of identity resilience.
Closing the Recovery Gap: One Platform for Unified Identity Protection
Modern businesses can’t afford a fragmented approach to identity protection. Whether you're cloud-first, hybrid, or still managing on-prem domains, you need a platform that understands and protects both AD and Entra ID as a unified system.
