A stolen laptop with an unencrypted drive is a data breach. Full stop. FileVault is your first line of defense, and it should be non-negotiable on every Mac in your organization.
FileVault: The Basics
FileVault is Apple's built-in full-disk encryption. On Apple Silicon Macs, the drive is encrypted by default at the hardware level (thanks to the Secure Enclave), but FileVault adds a layer: it requires authentication before the OS can decrypt and boot. Without FileVault enabled, anyone who gets physical access to your Mac can potentially access the data.
Deploying FileVault via MDM
You should never rely on employees to turn on FileVault themselves. Your MDM solution should enforce it. When deployed through MDM, FileVault enables silently at next login, and the recovery key gets escrowed (stored) in your MDM console. If an employee forgets their password or leaves the company, you can still unlock the machine. This is critical.
Recovery Key Management
Every FileVault-encrypted Mac has a recovery key. If that key is lost and the user password is forgotten, the data is gone permanently. MDM escrow means recovery keys are stored centrally and securely. Rotate keys periodically. Audit that escrow is working. One missed key on one laptop is all it takes for a bad day.
Beyond FileVault: Endpoint Security
Encryption protects data at rest. You still need protection against malware, phishing, and network attacks on running systems. The "Macs do not get viruses" era is long over. macOS threats are real and growing.
What to Deploy
- EDR (Endpoint Detection and Response): Tools like CrowdStrike Falcon, SentinelOne, or Huntress provide real-time threat detection and response on Mac. They go well beyond traditional antivirus.
- DNS filtering: Block malicious domains before they load. Solutions like Cisco Umbrella or Cloudflare Gateway work at the network level.
- Email security: Most attacks start with email. Phishing-resistant authentication and email filtering catch threats before they reach the endpoint.
macOS Built-In Security
Apple has invested heavily in platform security. XProtect, Gatekeeper, System Integrity Protection, and the Secure Enclave provide strong foundations. But these are baseline protections designed for consumers. Business environments need the visibility, control, and incident response capabilities that third-party tools provide.
The Compliance Connection
Cyber insurance, SOC 2, PIPEDA, HIPAA: all require encryption and endpoint protection. With FileVault managed through MDM and EDR deployed across your fleet, you can demonstrate these controls with actual compliance reports rather than "we told everyone to turn it on." Learn more about compliance for your business.
Getting Started
Priority one: enforce FileVault on every Mac via MDM with key escrow. Priority two: deploy an EDR solution. Priority three: add DNS filtering. These three layers cover the majority of endpoint risk for a small business. If you need help selecting and deploying the right tools for your Mac fleet, reach out for a free assessment.
