Top Cyber Asset Attack Surface Management (CAASM) Tools

Securing your attack surface starts with getting a clear picture of your assets. As defined in NIST‚Äôs special publication, an asset means ‚Äė‚ÄôAnything that has value to a person or organization.‚Äô‚Äô¬†

Then, what does value mean in an organization?

Almost everything used to operate a business has value to an organization.

  • Data - you store in cloud services like AWS and Azure.
  • Communication - by tools like Slack and Zoom.
  • Automation - by code repositories like GitHub and Bitbucket.
    and more tools can be defined as where the value is created in an organization.

In terms of cybersecurity, these values must be monitored to detect if any security vulnerabilities are reaching them. Thereby, vulnerabilities can be solved immediately, or preventive actions can be taken before any value gets defective or lost, such as accidental deletion of important data or unauthorized access to internal resources. This article will help you compare the top CAASM tools and their key features.

How does CAASM help you keep the values of your organization safe?

Modern companies have cloud services and tens, even hundreds of tools in their Tech Stack that generate assets continuously. So, the number of assets can reach tens of thousands.

Security teams need to check these tools and included assets to answer any concerns or detect vulnerabilities. So, how can security teams keep on top of such a wide range of assets with robust security processes? It’s almost impossible to manage them without a centralized and automated manner. There, CAASM comes into play by integrating your tools, enabling you to discover, monitor, classify, and secure your assets from one hand.

CAASM is a technology that helps organizations bring together and standardize their all assets, which are typically spread out across a wide IT environment. It enables users to monitor, query, and centralize internal and external data, regardless of where it is stored, and detect vulnerabilities.

Now, we’ll look into which companies offer what solutions and their key features.
