Attack Surface Management (ASM) Software

Attack Surface Management

What is Attack Surface Management Software?

ASM is the overarching strategy to reduce potential attack points. It encompasses both internal and external environments and is about understanding and reducing the total number of points or "attack vectors" where an unauthorized user could potentially access a system. There are interconnected solutions to ASM, such as cyber asset attack surface management (CAASM) which is about knowing and securing everything you own, and external attack surface management (EASM) which focuses on securing what others can see or access from outside your network. Each plays a crucial role in a comprehensive cybersecurity strategy.
