Deprecated Features

Removing Support for TLS 1.0/1.1

Transport Layer Security (TLS) 1.0 and 1.1 were deprecated by the IETF in June 2018, due to security issues.

TOS has supported TLS 1.2 for more than five years and for most services, TLS 1.2 is mandatory. Therefore, from TOS release R23-2, Tufin will no longer support the old TLS versions for email and LDAP communications.
