RiskXchange Attack Surface Management is a commercial external attack surface management tool by RiskXchange. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams managing multiple cloud environments will get the most from Microsoft Defender EASM because it actually finds unmanaged assets and shadow IT that your teams don't know exist, then feeds that inventory directly into your existing Microsoft security stack. Its integration with Microsoft Defender for Cloud and Security Copilot means you're not bolting on another disconnected tool; discovery flows straight into your asset management and risk prioritization workflows. Skip this if your organization runs primarily on non-Microsoft infrastructure or lacks the Defender for Cloud footprint to make the integration pay off.
RiskXchange Attack Surface Management
Mid-market and enterprise security teams drowning in unknown assets and third-party risk will find RiskXchange Attack Surface Management's continuous external discovery worthwhile, particularly those managing sprawling cloud footprints across multiple regions. The platform's 24/7 monitoring with real-time alerts and automated asset enumeration directly addresses the ID.AM and DE.CM gaps most organizations struggle with, and the breach monitoring feeds mean you catch credential leaks before attackers use them. Skip this if your primary need is remediation orchestration or patching integration; RiskXchange surfaces the problem and guides response, but stops short of closing the loop with your ticketing system.
