The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The SANDBOXIE L.T.D digital certificate does not guarantee that a signed application is safe to run, but rather informs the user that the software was digitally signed by SANDBOXIE L.T.D and verified by a trusted Certificate Authority (CA).
Sandboxie is a proprietary sandbox-based isolation program that creates a sandbox-like isolated operating environment in which applications can be run or installed without permanently modifying the local or mapped drive. An isolated virtual environment allows controlled testing of untrusted programs and web surfing.

“Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer. Sandboxie extends the operating system (OS) with sandboxing capabilities by blending into it. Applications can never access hardware such as disk storage directly, they have to ask the OS to do it for them. Since Sandboxie integrates into the OS, it can do what it does without risk of being circumvented.”
