As identity-based threats continue to rise, organizations have invested heavily in protecting users and credentials. However, identity is only one part of the equation.
Modern identity security now depends on protecting the access plane, such as Microsoft Entra ID configurations, Microsoft Intune policies, expanding device footprints, and BitLocker keys to ensure consistent and secure access control.
When access-related configurations fail or change unexpectedly, the impact reaches beyond security concerns into large-scale business disruptions.
In this blog post, we will explore what the access plane is, why it plays a critical role in modern identity strategies, and how protecting it helps organizations maintain secure and uninterrupted access. We will also look at how Veeam Data Cloud for Microsoft Entra ID enables visibility and recovery across these critical access components.
Where Identity and Access Connect
For years, identity has been synonymous with users. In modern environments, however, identity extends far beyond a username and password.
Access is now governed by a combination of devices, policies, and encryption mechanisms that work together to determine how and when users can interact with systems.
The access plane sits at the center of this shift.
If identity defines who you are, the access plane defines whether or not you can actually get in. When access-related objects or policies are affected, the consequences are immediate and highly visible, from widespread lockouts to gaps in enforcement.
Entra ID Access Plane Explained
The access plane represents the collection of controls that shape access decisions in real time.
For example, when a user attempts to sign in to a corporate application, access is not granted based on credentials alone. That user’s device must also meet compliance requirements, applicable policies must allow access, and encryption safeguards must be intact. All of these checks are enforced through the access plane.
This includes:
- Devices that establish endpoint posture and compliance
- Configuration policies such as Intune settings that enforce security requirements. (For a deeper look at how Intune policies impact access and why protecting them matters, explore our blog on Intune policy backup)
- Encryption and recovery elements including BitLocker keys that enable device access and restoration
A user may have valid credentials, but without a compliant device or the right policy alignment, access is denied. This shift reflects how organizations are moving toward context-driven access models that continuously evaluate risk and posture.
The Role of Access Plane in Modern Identity
Modern security strategies such as zero trust have fundamentally changed how access is granted. Instead of relying on a one-time authentication event, access decisions are now continuously evaluated using signals like device health, policy compliance, and encryption status.
These configurations directly influence whether access is approved, denied, or restricted at any given moment. Because of this, they play a central role in maintaining both security and operational continuity.
When the access plane is functioning correctly, users experience seamless and secure access. But when disruptions occur, the impact on business productivity is immediate. Users may be locked out of applications, or in some cases, unintended access may be granted if controls are weakened.
In both scenarios, the organization is exposed.

The Real Impact of Access Plane Failures
The risks associated with access disruption show up in everyday operational challenges. The following scenarios reflect common issues that can directly impact your organization’s ability to maintain secure and reliable access.
- Device lockout at scale
- A misconfigured Intune policy marks devices as non-compliant across the environment
- Users lose access to business-critical applications simultaneously
- Operations are disrupted at scale
- Lost or inaccessible BitLocker keys
- A device enters recovery mode, but the required key cannot be accessed
- Users are unable to regain access to their systems
- Productivity is delayed and IT teams must intervene manually
- Policy drift or accidental changes
- Configuration policies change due to human error or overlapping updates
- Security baselines shift without clear visibility
- Access conditions become inconsistent or weakened
These examples highlight a critical gap in identity and access protection strategies. While these configurations directly control access, the ability to track changes, retain historical versions, and recover from previous states is often limited.
Where Current Access Strategies Fall Short
Many organizations assume that identity platforms fully handle the protection of access configurations. However, as outlined in the Entra ID shared responsibility model, this is not the case.
In practice, responsibility is split as follows:
- Microsoft is responsible for:
- Platform availability and infrastructure
- Maintaining the underlying identity service
- Organizations are responsible for:
- Configuration of policies and access controls
- Device compliance and management settings
- Protection and recovery of identity-related data
This means that while access policies, device configurations, and encryption keys are critical to enforcing security, the responsibility for protecting and restoring them ultimately falls on the organization.

Protecting the Access Plane with Veeam Data Cloud
As the access plane becomes more central to operations, protecting it requires the same level of attention as identity itself.
With expanded support in Veeam Data Cloud for Microsoft Entra ID, organizations can now protect additional components of the access plane, including devices and BitLocker keys.
This builds on existing capabilities for protecting Intune configuration policiesand provides several key advantages:
- Centralized visibility across environments and tenants
- Extended retention for critical configurations beyond native limitations
- Granular recovery of policies, device-related data, and encryption keys
- Greater control when responding to misconfigurations or unexpected changes
By focusing on these areas, organizations can move beyond simply protecting data. They can restore access when it matters most.
The Bigger Picture: Resilience Beyond Identity
Identity remains a foundational element of security. However, it is no longer sufficient on its own.
True resilience now requires protecting the full scope of what enables access, including identities, access conditions, and device posture.
The access plane unites these elements. Protecting it ensures that users can securely and consistently access the resources they need, even in the face of disruption.
Ultimately, protecting the access plane is not just about security. It is about maintaining continuity across the business.
