Missing Server Name Indication (SNI) Support in Legacy Protocols

6/10 Medium

SNI is only supported in TLS 1.x, not SSL 3.0. Additionally, older clients (MSIE on XP, Java 6, Android versions, and some programming languages) lack SNI support, causing certificate errors when multiple certificates are hosted on the same IP address.

Query: “What are the most common pain points with SSL/TLS for developers in 2025?”4/9/2026

TLS extensions like Server Name Indication (SNI) can only be done with TLS1.x. No SNI support for SSL 3.0, Android (depending on application), MSIE on XP, Java 6 and various other programming languages. This will cause problems when the server has multiple certificates on the same IP address.
