JUMPSEC Jargon Buster - Courtney Cole explains what is the difference between external & internal Managed Vulnerability Scanning?

External Managed Vulnerability Scanning only targets infrastructure on the public Internet perimeter, such as web applications and VPN servers. By contrast, Internal Managed Vulnerability Scanning focuses only on your internal infrastructure, such as user workstations, file servers and so on. External and Internal Managed Vulnerability Scanning work well together, but depending on your company’s risk factor and expectations, one might offer greater benefits than the other.
