Client certificates

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.


Use this certificate for email protection

Class 1


Provides secure email services and client authentication. Enable your clients to encrypt and digitally sign email communications.

Note: This certificate does not include private key escrow and recovery.

Class 2

TLS/SSL Certificates

Encryption is the backbone of internet security

Transport Layer Security (TLS) certificates—most commonly known as SSL, or digital certificates—are the foundation of a safe and secure internet. TLS/SSL certificates secure internet connections by encrypting data sent between your browser, the website you’re visiting, and the website server. They ensure that data is transmitted privately and without modifications, loss or theft.


Give customers a clearer picture of who you are


Jane Doe is an anonymous, unidentifiable internet user whose actions can’t be tracked. Would you trust her with your personal information?


Domain Validated (DV)

Domain Validated (DV) certificates provide the lowest level of identity authentication, meaning anonymous entities can get a certificate.

Jane Does can remain anonymous at this level.

Organization Validated (OV)

Organization Validated (OV) certificates provide additional checks to ensure identity and brand protections.

Jane Doe can no longer hide in the shadows at this level.

Extended Validation (EV)

Extended Validation (EV) certificates guarantee the highest standard of identity and brand protections. EVs signal that transactions are secure.

Jane Doe is thoroughly identified

Verified Mark Certificates (VMCs)

Verified Mark Certificates (VMCs) allow you to render your logo next to the “sender” field in email clients so that users see your mark—and that your organization has been authenticated—before they even open your message. It’s the email equivalent of a checkmark on social media, with added validation and security requirements to help protect your customers and your brand against phishing and spoofing attacks.

How do VMCs work?

Logo-verified email is part of a groundbreaking initiative—in cooperation with Brand Indicators for Message Identification (BIMI) and email client providers— to promote a consistent, trusted and visually authenticatable email experience for both businesses and consumers.
