SSLi

SSLi is an acronym with multiple meanings across different domains. There is no single universally recognized definition, and the interpretation of SSLi is highly context-dependent.

In information security and networking, SSLi is sometimes used to denote SSL inspection or TLS interception. This refers to the practice of terminating TLS sessions at a security device (such as a firewall or proxy), decrypting the traffic to inspect it for threats, and then re-encrypting it before forwarding it to the end user. SSLi implementations vary in capability and scope, and they raise considerations about privacy, legal compliance, and user consent. The term is not standardized, and different vendors may describe the feature with different names.

In software development and API design, SSLi is occasionally used to describe a Secure Socket Layer interface or library—an abstraction that provides programmatic access to TLS/SSL routines such as handshake management, certificate validation, and encryption. The exact API surface and capabilities depend on the platform or vendor; SSLi components are typically integrated into larger security stacks or communication modules.

Outside security and software, SSLi has been used as an acronym in various projects and organizations, often as internal shorthand or a project name. Because there is no universally accepted standard, the meaning should be inferred from the surrounding text. If you have a specific context for SSLi, that context will determine the most accurate interpretation.
