Attack surface, explained.
Plain-English guides to the concepts behind modern exposure management — no jargon, no fluff.
What is Attack Surface Management (ASM)?
Attack Surface Management (ASM) is the continuous discovery, inventory and monitoring of everything an organization exposes to the internet. Here's how it works and why it matters.
EASM vs Vulnerability Scanning: what's the difference?
EASM discovers what you expose; vulnerability scanning checks known targets for known flaws. Here's how external attack surface management and vulnerability scanning differ and complement each other.
What is Continuous Threat Exposure Management (CTEM)?
CTEM is a continuous, five-stage program for finding and reducing the exposures that matter most. Here's what Continuous Threat Exposure Management means and how to operate it.
Subdomain Takeover: what it is and how to prevent it
