7 Best Attack Surface Management Tools for Risk Reduction

Did you know cyberattacks hit a business every 39 seconds? That’s right. Every minute counts when it comes to security. Your company’s digital footprint, basically the sites, apps, devices, and servers connected to the web, as such, can be a goldmine for hackers if not managed carefully. The bigger it gets, the more chances for intruders to sneak in.

However, with attack surface management tools, you can scan it to spot gaps before hackers do. Acting as your security guards, these tools patrol your network, cloud assets, and third-party links 24/7.

Let us thus walk you through some of the leading attack surface monitoring tools that will help you keep your digital trail a secret, come what may.

What are Attack Surface Management Tools?

An attack surface management tool is a cybersecurity software that tracks every part of your network exposed to potential attacks. It continuously scans your digital exterior to spot vulnerabilities, guide fixes, and improve your defence posture.

While some tools focus on internal systems, others look beyond, inspecting external assets and third-party risks. Those covering external threats are often called external attack surface management (EASM) tools. They provide a view of your attack surface from a hacker’s point of view. In short, these tools help you spot and manage risks that slip past traditional security setups.
