A method of operating a network message interceptor for enforcing a security policy for communication over a network between first and second network endpoints, the interceptor being in communication with the network and external to the first and second endpoints, the network including transport layer security, and the security policy identifying at least one valid security standards for communication over the network, the method comprising the steps of: intercepting a handshake message transmitted over the network between the first and second endpoints; extracting from the handshake message an identification of a security standard selected for the communication between the first and second endpoints; determining a validity status of the identified security standard based on the security policy; and preventing communication between the first and second endpoints based on a negatively determined validity status of the identified security standard.
