\u00a0<\/span><\/p>\nThe pattern holds across multiple studies: attackers don’t need to break through a well-defended system when there’s an unmonitored one sitting right next to it.<\/span>\u00a0<\/span><\/p>\n<\/span>What Is the Difference Between MDM and EDR?<\/span><\/h3>\nThe two get used interchangeably, but they solve different problems. Mobile device management, or MDM, is about managing a device: enforcing settings, pushing updates, controlling what’s installed. Endpoint detection and response, or EDR, is about watching behavior on that device and responding when something looks wrong, even when the specific threat has never been seen before.<\/span>\u00a0<\/span><\/p>\nA well-managed device isn’t automatically a monitored one, and a monitored device isn’t automatically configured correctly. Reducing unmanaged device security risks usually means having both, not choosing between them.<\/span>\u00a0<\/span><\/p>\n
<\/h3>\n<\/span>Visibility, Detection, and Lifecycle: The Layers That Actually Matter<\/span><\/h3>\nBeyond MDM and EDR individually, closing this gap comes down to three things working together, not one tool solving everything.<\/span>\u00a0<\/span><\/p>\nVisibility and inventory.<\/span><\/b> You can’t protect a device you don’t know exists. An accurate, current inventory is the starting point for everything else.<\/span>\u00a0<\/span><\/p>\nDetection and response.<\/span><\/b> Once a device is known, it needs ongoing monitoring, not a one-time check.<\/span>\u00a0<\/span><\/p>\nEncryption and lifecycle management.<\/span><\/b> A device that leaves the company, whether through an employee’s departure or hardware replacement, requires a defined process for wiping, decommissioning, or retiring it. Otherwise, it remains a live risk long after anyone is thinking about it.<\/span>\u00a0<\/span><\/p>\n<\/span>Do You Need EDR If You Already Have Antivirus?<\/span><\/h3>\nTraditional antivirus looks for known threats, files, and patterns that have already been identified elsewhere. That approach still catches plenty, but it struggles against anything new or slightly modified. EDR closes that gap by monitoring for suspicious behavior rather than only matching known files.<\/span>\u00a0<\/span><\/p>\nFor a device that isn’t centrally managed, that difference matters more, not less, because there are fewer other safeguards around it.<\/span>\u00a0<\/span><\/p>\n<\/span>How to Reduce BYOD Risk<\/span><\/h3>\nNone of this requires banning personal devices or slowing people down. A few principles cover most of the ground:<\/span>\u00a0<\/span><\/p>\n\n- Keep an inventory that reflects reality, not just what the company issued.<\/span>\u00a0<\/span><\/li>\n
- Require encryption on anything that touches company data, personal or not.<\/span>\u00a0<\/span><\/li>\n
- Define what happens to a device the moment someone leaves, before it becomes an afterthought.<\/span>\u00a0<\/span><\/li>\n
- Treat detection as a baseline for any device with access, not a bonus for company-owned equipment only.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
None of these are complicated on their own. What’s usually missing is someone accountable for making sure they happen consistently.<\/span>\u00a0<\/span><\/p>\n
