The 1% of Ports Causing 90% of Breaches

Administrative ports like SSH, RDP, RPC, WMI, SMB and more are the main attack vectors in most ransomware campaigns and attack tool kits. In fact, Remote Desktop Protocol (RDP) alone was involved in 90% of ransomware incidents investigated in 2024.

While legacy microsegmentation solutions may block most of the 65,535 available network ports, they typically leave these privileged administrative ports permanently open, enabling lateral movement and essentially leaving the network highly vulnerable. Learn how automated, identity-aligned microsegmentation reinforced with network-layer MFA closes the privileged port gap that gives attackers free rein in your network.
