Legacy protocols such as remote desktop protocol (RDP), server message block (SMB), and Telnet were not designed with modern security threats in mind and are frequently exploited by ransomware to spread across networks. These protocols often lack robust encryption and multi-factor authentication, making them prime targets for lateral movement. Eradicating these from internal subnets and replacing them with secure, identity-aware proxies significantly hardens the environment. See how we evolve past legacy protocols.
