Xpanse provides a complete, accurate and continuously updated inventory of all global internet-facing assets. This allows you to discover, evaluate, and mitigate cyber attack surface risks. You can also evaluate supplier risk and assess the security of acquired companies.
Manual asset inventory maintenance is slow and prone to error. An outside-in view of your attack surface catches assets and exposures you never knew existed to help with attack surface reduction.
Get ahead of your ransomware risk assessment by discovering and remediating RDP exposures, the leading attack vector in ransomware attacks. Find exposed assets before attackers do.
Integration with Cortex XSOAR, Prisma Cloud, and our broader portfolio allows our ASM findings to enhance security workflows, and secure unknown, unmanaged risks on your cloud attack surface.
In this era of hybrid work, shadow IT creates an increasingly serious security risk. Microsoft Defender External Attack Surface Management helps cloud security teams see unknown and unmanaged resources outside the firewall.
