10 Attack Surface Management Tools to Know in 2025

Notable Attack Surface Management Solutions

CyCognito

The CyCognito platform addresses today’s exposure management requirements by taking an automated multi-faceted approach in identifying and remediating critical issues based on their business impact, rather than focusing on the generic severity of the threat alone. To do this you need a platform that is continuously monitoring the attack surface for changes and provides intelligent prioritization that incorporates organizations context.

The CyCognito platform addresses today’s vulnerability management requirements by:

• Maintaining an asset inventory with classification of the entire external attack surface, including exposed on-premise and cloud-hosted assets like web applications, IP addresses, domains and certificates, eliminating the need to rely on outdated or incomplete information from collaboration tools, spreadsheets, or emails. This approach significantly reduces the burden of tedious, error-prone and costly processes.
• Application security testing, including dynamic application security testing, or DAST, which uncovers complex issues and validates known issues, with low false positives. Each exploited asset is assigned a security grade based on its criticality to the business.
• Prioritizing critical issues, guiding security teams to focus on the most urgent threats. Our unique risk-based prioritization analysis goes beyond the common vulnerability scoring system (CVSS), and incorporates factors like asset discoverability, asset attractiveness, exploitability, business impact and remediation complexity.
• Integrated tactical threat intelligence identifies the handful of attack vectors that pose the greatest risk.
• Streamlining communications between remediation teams by providing comprehensive, verifiable evidence for each exploited asset. This evidence includes detailed risk assessments, asset ownership information, and actionable remediation guidance. The platform seamlessly integrates with SIEM, SOAR and ticketing system tools like Jira, ServiceNow and Splunk to facilitate information sharing and collaboration.
