What are Attack Surface Management Platforms?
Attack surface management (ASM) platforms enables organizations to monitor and manage their attack surface risk. Attack surface management software allows companies to view cyber risks and attack vectors related to external digital assets outside of their firewall. These platforms continuously scan and assess an organization’s digital infrastructure, including networks, systems, applications, and endpoints, to detect vulnerabilities, misconfigurations, and exposed assets that could be exploited by attackers. Compare and read user reviews of the best Attack Surface Management platforms currently available using the table below. This list is updated regularly.

Reflectiz
Reflectiz
Most attack surface management tools map infrastructure: domains, hosts, exposed services, unpatched software. Reflectiz covers the layer they do not instrument, the code executing inside the visitor's browser. Every website runs third-party scripts, pixels, trackers, iFrames, and open-source libraries loaded from vendors the organization does not control, frequently pulling in fourth-party code several relationships deep. A site can present a completely clean external attack surface and still be actively skimmed, because the malicious code arrives through a trusted vendor's CDN rather than an exposed port. Reflectiz continuously inventories this web execution surface, baselines the behavior of every component, and alerts the moment behavior deviates. Deployment requires no code changes, no agents, and no access to customer data, typically reaching full coverage within one business day.Starting Price: $5000/year -
