    The validation seemed a bit exhaustive, to be honest. The certificate was issued in 6 days. Security wise, it’s a powerful product, and we’re very happy with its performance.

    This certificate secures our internal emails and documents, and, on top of that, enables the two-factor user authentication. I can’t believe it is so affordable.

Here is a list of the most common questions our customers have when buying a Comodo CPAC SSL Certificate:

Comodo (Sectigo) Personal Authentication Certificates provide you the highest level of protection by enabling end-to-end encryption of your email communications. By signing and encrypting your outgoing email messages, you protect them from Man-in-the-Middle attacks, https proxies, or packet-sniffers, therefore your messages can’t be intercepted and decrypted by a malicious third party.

Encrypting Email Messages guarantees their privacy and integrity, while digitally signing the messages authenticates you as being the genuine sender. In this way, you will secure yourself and your business from accidental or fraudulent data exposures, privacy breaches and other potential security threats associated with the business communication. 


Comodo (Sectigo) Personal Authentication Certificate lets you easily sign any valuable and critical personal or company document, therefore ensuring compliance with industry requirements of digitally signed documents. By digitally signing the document, you identify yourself as the authentic document signer and certify its integrity by proving that your document hasn’t been altered since it was signed. In this way, CPAC SSL Certificates help you migrate from ink & paper to digital workflows of contracts, sign-offs, request forms and other important company documents, working in tandem with or replacing the visible signature feature in Microsoft® products such as Microsoft Office Suite, Open Office Suite, VBA Macros and more.



Comodo (now Sectigo) Personal Authentication Certificate helps business reduce the risks and threats associated with using standard passwords through enabling the two-factor authentication of users. If you need a stronger guarantee that the person logging into your company network or account is your legitimate employee, CPAC SSL Certificates will allow you to secure your sensitive and private customer or corporate data by enabling the industry standard used by banks all over the world – two-factor authentication – seamlessly integrating the certificate as a second authentication element. In this way, you will protect your company access, including remote, from any hackers attempting to steal usernames and passwords. 

Comodo (now Sectigo) Personal Authentication Certificates were designed for individuals and businesses who are looking at implementing the best web security practices, such as email & document encryption and user two-factor authentication. However, each CPAC SSL Certificate was designed to fit a particular need. Just like DV, BV, and EV SSL Certificates, CPAC SSL Certificates come with different validation requirements which enable certain certificate fields:

  • CPAC Basic – requires Domain Control and displays only your email in the SSL Certificate
  • CPAC Pro – requires Domain Control and Identity Verification in order to display your email, First and Last Name in the SSL Certificate
  • CPAC Enterprise – requires Domain Control, Identity Verification, and Organization Validation in order to display your email, First and Last Name, as well as Company Name and Address in the SSL Certificate.

Based on your actual needs, you can now decide which Comodo Personal Authentication Certificate is the best option for you, providing you an enhanced web security of your business activity. 

To add your Company Name and TAX/VAT number, you have to login into your SSL Dragon Account and follow these steps:
