Why Your Defense In Depth Plan Might Be All Defense And No Depth
Symantec, Tuesday, September 2nd, 2025
Welcome to your DiD starter pack: This is how smart teams layer detection and response across cloud and hybrid environments
- In the cloud, traditional perimeters dissolve fast. Knowing who has access to what serves as your first and most important layer.
- Visibility also needs to extend to endpoints, because if you can't see it, you can't really secure it.
- Speed in threat detection and response can make or break your DiD program, but resilience is what decides if your defenses hold.
One dangerous assumption can take down even a behemoth of a business: A single security control is enough to defend assets and operations. For those who'd select 'strongly disagree' on that statement (hopefully everyone reading this), Defense in Depth (DiD) is the framework for you. DiD goes beyond basic prevention tools like firewalls to create a stack of defenses-where if one layer fails, another stands ready.
