The Essential Buyer’s Guide To Attack Surface Management (ASM)

Download the guide

Insights and guidance for cybersecurity professionals when selecting an ASM solution.

Most cybersecurity teams are stretched thin, managing an overwhelming volume of data, alerts, and disconnected tools – all while their attack surface expands. That’s why this ASM buyer’s guide is so valuable. It arms you with the information and questions you need to make a fully informed decision when choosing a solution that can scale with their attack surface, reduce exposure to threats, and minimize alert fatigue for security teams.

 

What’s in the ASM Buyer’s Guide:

  • An introduction to ASM: Specifically, the value it delivers to organizations and how it supports compliance and enhances areas like third-party risk management, offensive security, and vulnerability management.
  • 10 questions to ask vendors: A list of critical questions covering scan frequency, vulnerability prioritization, exploitability testing (PoCs), and offensive research capabilities to help you choose the right partner for your security strategy.
  • The maturity spectrum: A self-evaluation model outlining five levels of program development, from “Cyber reactive” (Level 0) to “True ASM” (Level 5).
  • Measuring the ROI: Data-driven approaches to demonstrate improvement and a clear return on investment to stakeholders.

INTRODUCTION: HOW Attack Surface Management ENHANCES SECURITY POSTURE AND REDUCES RISK  

You can’t protect what you can’t see. It’s as simple as that. However, any cyber professional will tell you that running an ASM program is anything but simple. You’re not just in a race with external attackers – you’re also trying to keep pace with constant internal changes. Whether it’s the engineering team accidentally creating an open code repo, HR implementing a new third-party platform, or marketing deploying a campaign on infrastructure that’s unseen by security. The attack surface is always evolving and expanding – traditionally, it’s been difficult to keep up

This is where ASM is crucial. By continuously discovering assets, checking them for exploitable vulnerabilities, and ensuring your security posture reflects your actual digital footprint, ASM helps reduce this risk. ASM provides three core benefits:
 

  1. Discover previously unknown exposures.
  2. Support faster incident response and remediation.
  3. Reduce overall risk through informed decision-making.

To truly realize these benefits, we must acknowledge that the traditional concept of network perimeter security is no longer enough to defend against today’s evolving cyber threats. The adoption of cloud tools has expanded an organization’s true attack surface exponentially – exposing them to risks like phishing, leaked credentials, and ransomware.
