Group-IB Attack Surface Management vs Microsoft Defender EASM: 2026 Comparison

Group-IB Attack Surface Management

Mid-market and enterprise security teams drowning in unmanaged internet-facing assets will benefit most from Group-IB Attack Surface Management because it actually finds shadow infrastructure and misconfigured services that your internal teams don't know exist. The platform covers ID.AM and ID.RA in NIST CSF 2.0 with continuous discovery and risk scoring tied to actual threat intelligence, not just CVE databases. Skip this if your organization has fewer than 50 people or you're looking for a tool that also handles internal network segmentation and response automation; Group-IB stops at surfacing and prioritizing what's exposed.

Microsoft Defender EASM

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.
