Full Disk Encryption: Should Bitdefender or Intune Manage It?

TL;DR. Already paying for Intune (M365 Business Premium, E3, or above) on a mostly-Windows fleet? Let Intune manage BitLocker. Conditional Access integration is tighter and recovery keys land in Entra ID where IT already lives. Have the Bitdefender FDE module on with a mixed Mac and Windows fleet? Let GravityZone handle both. Single console, single key store, no double-policy fights. Running both is where things break.

What’s actually being compared?

Two specific products. Bitdefender’s Full Disk Encryption module is an add-on inside GravityZone that manages native BitLocker on Windows and native FileVault on macOS. It does not write its own crypto. It sets policy, triggers the encrypt, and escrows the recovery key to the GravityZone console.

On the other side: Intune BitLocker policy (inside Intune) plus, on Mac, a FileVault configuration profile via the macOS MDM channel. Same shape: native OS encryption, MDM tells the OS to switch on, recovery key goes to Entra ID for BitLocker or to Intune for FileVault.

Both manage the same two encryption stacks. The difference is where the keys live, what else sits in the same console, and how the rest of your security policy reads encryption state.

What does each do well?

Intune wins on Microsoft-shop integration. BitLocker recovery keys auto-escrow to Entra ID. Conditional Access reads device-encryption state directly and blocks sign-ins from non-encrypted machines. Autopilot folds the encryption trigger into out-of-box provisioning. Windows reporting is mature.

Bitdefender wins on cross-platform parity and one-pane operations. The same console that shows EDR alerts, patch status and risk score also shows encryption state. macOS support is closer to parity than Intune’s FileVault story. One agent, one bill, one place to look.

For shops without an Intune licence (Google Workspace organisations, Hexnode-managed fleets via MDM), Bitdefender FDE is the clean answer. There is no “Intune for FDE only” SKU at a sensible price.

Where do they overlap and why having both is bad

Switch Bitdefender FDE on and push an Intune BitLocker policy to the same Windows fleet, and three things go wrong.

Recovery-key chaos. BitLocker has one recovery key per protector. Whoever escrows first wins. The other tool sees a key it can’t read and reports “non-compliant” forever. Help desk gets two answers when a user calls in, locked out at 7am. Auditors get two reports that disagree.

Conflicting policy enforcement. Intune wants AES-256 XTS. Bitdefender wants AES-128 XTS (or the reverse, depending on baseline). First agent encrypts. Second agent flags non-compliant and either sits there or tries to re-encrypt. We’ve watched full re-encryption cycles kick off on production laptops because of a policy fight neither team noticed.

Compliance reporting that lies. Conditional Access state reads from Intune. The GravityZone risk dashboard reads from Bitdefender. Half the fleet is green in one, red in the other.

Pick one. Document it. Switch the other off.

When does Intune win?

• M365 Business Premium, E3, or E5: Intune is paid for. Adding a separate FDE tool spends money you’ve already spent. See the Microsoft 365 page for licensing detail.
• Conditional Access compliance is load-bearing. If your sign-in policy says “device must be compliant or no Outlook”, that signal builds from Intune-managed state. A separate tool driving encryption introduces a sync gap Conditional Access can’t see.
• Autopilot is your provisioning path. BitLocker trigger inside the Enrollment Status Page is the cleanest zero-touch encryption flow there is.
• Windows-only fleet. Intune’s macOS gap doesn’t matter if there are no Macs.

When does Bitdefender win?

• Mixed Mac and Windows, especially Mac-heavy. FileVault management is more polished than Intune’s, and one console covers both.
• No M365 dependency. Google Workspace shops, Zoho shops, anywhere you would otherwise buy Intune purely for encryption. The Bitdefender FDE module costs less per endpoint than a standalone Intune Plan 1 SKU, so it usually works out cheaper.
• You already run GravityZone for EDR or XDR. Switching FDE on is a tick-box and a policy push, not a new vendor.
• One-security-console philosophy. EDR, patch, encryption, email security in one place.

Tie-breaker we use in audits: count the Macs. More than 30% of the fleet, Bitdefender FDE almost always wins regardless of M365 SKU.

Comparison at a glance

So which one should you actually pick?

Walk the decision tree. On M365 Business Premium or E3+, mostly Windows, Conditional Access in active use? Intune for BitLocker. Done.

Mostly Macs, no M365 SKU that includes Intune, or already on GravityZone for EDR? Bitdefender FDE. Done.

Genuinely mixed fleet with Intune and GravityZone licensing in place? Split it per OS: Intune for BitLocker on Windows, Bitdefender FDE for FileVault on Mac, with the other tool’s encryption module explicitly switched off. That’s the only split we’ll defend, and we still audit it twice a year because policy drift is real.

Thirty minutes, one engineer, no pitch. We review your current encryption coverage (devices, OS, tool), audit your recovery-key store (where keys live, who has access, whether they’ve ever actually been tested), and give a written recommendation on which tool wins for your fleet. Running both already? We’ll tell you which to switch off and how to migrate the keys cleanly.
