Typically, hackers exploit one or more vulnerabilities in an organization to enter its network and commit a crime such as stealing data, locking the critical systems to demand a ransom, exhausting the organization’s digital resources, and more. 

The vulnerabilities or the areas that are susceptible to these attacks is called an attack surface. It includes both physical areas such as data centers and digital areas such as unpatched user devices, an unprotected network, and more. 

Organizations routinely assess their vulnerabilities and try to address the gaps. This is called attack surface analysis. Many strategies and tools that help with this attack surface analysis and organizations take the information gathered from these tools to understand their current security state and to take further action to mitigate an attack.

In this article, we will take a look at some of the best attack surface monitoring tools and their features to help you decide the best fit for your organization.
