What is digital signing?

Signing is a cryptographic technique that was designed to validate the integrity and authenticity of a document, file, or email. Signing ensures the sender and the recipient of a file or message that the data is reliable, safe, and has not been tampered with.

Our signing solutions will defend your communication against hackers and eavesdroppers, and ensure your customers that your, or their, data has not been tampered with.
