How to secure your website with TLS/SSL certificates

DigiCert TLS/SSL certificates provide two vital layers of website security: encryption and identity validation.

First, our certificates encrypt sensitive information—like credit card transactions, personal information and user passwords—using a 2048-bit algorithm. This ensures that even if the data is intercepted by a malicious third party, it cannot be read.

But encryption, by itself, is only half the equation. Our rigorous validation process goes a step further than standard (and often low cost) SSL to establish concrete proof of your identity. That way users can be sure that the person on the other side of the transaction is exactly who they claim to be.
