Message Privacy -
Email privacy protects your emails against unauthorized access. If your email is encrypted with S/MIME, then your emails are only readable by the intended recipient. Any message or documents from the emails will be confidential between the sender and receiver.
Message Integrity -
S/MIME certificates ensure that the inbox's message is the same message that the sender has sent. When a message is decrypted before reaching the receiver, it verifies the email content to ensure the sender's message is unchanged. If any changes are found in the email, then the decryption process fails, and hence, S/MIME certificates help you maintain the message integrity.
Tamper prevention -
Your email will be safe from tampering if you encrypt it with S/MIME Certificates. It prevents malicious applications from editing your email and maintains integrity. It ensures receivers that the email they are about to open has not been tampered with and is safe for them to read.
Unaltered contents -
Emails can't be modified when you encrypt them with S/MIME. S/MIME encrypted emails can only be read. The recipient will be notified if the original email is altered or modified in any way by an unauthorized third party.
Proof of authorship -
It assures the recipient that the email they received is from the original sender. A secure email will display the recipient's relevant cues through a digital signature that guarantees email integrity and ensures message privacy. The digital signatures prove the authorship of the sender.
