Client Certificates

Encrypt email with S/MIME, enable two-factor
authentication, and implement strong digital trust
practices throughout your organization with highly
versatile client certificates.

What is a client certificate?

Without two-factor authentication (2FA), email signing, and document signing, your organization is only as secure as your weakest password. Client certificates—also known as personal ID certificates—are used to concretely identify and validate individual users. That way you’re able to control what each user can and cannot access and encrypt and sign communications they send and receive.

Control access

Allow and restrict access to apps, websites, databases and devices.

Sign communications

Sign and encrypt emails to protect against phishing and tampering.

Enable 2FA

Guard against hacked passwords by adding another layer of authentication.
