Green Means TRUST

When validating a website for an EV Multi-Domain Certificate, DigiCert complies with a process that is strictly defined by the CA/Browser Forum. In fact, DigiCert is a founding member of the CA/Browser Forum and assisted in developing the extended validation certificate and validation process. This process includes:

  • Verifying the legal, physical, and operational existence of the entity
  • Verifying that the identity of the entity matches official records
  • Verifying that the entity has exclusive right to use the domain specified
  • Verifying that the entity has properly authorized the issuance of the certificate

What does EV look like in Internet Explorer, Firefox, Chrome, Opera, and Safari?

As part of this process, one of our validation specialists contacts the requesting organization to confirm that they requested the certificate and that the applicant is authorized to receive the certificate on behalf of the organization. By maintaining this human element in the validation process, it is very likely that fraudulent or phishing-related activity will be detected.

To let users know that a website has an EV Certificate, browsers show more visual cues for sites secured with EV Certificates. EV Certificates include the following visual benefits:

  • Green in the address bar (green bar or issuance name, see above)
  • Website owner's company name in the address bar
  • https:// at the beginning of the domain name
  • Padlock in the address bar
  • Organization information in the certificate details

Fast, thorough, and easily understood support. They don't throw jargon around to sound cool.

Setting up SSL Certs for a large 500 user, 1500 node network to lock down routers and firewalls for PCI compliance. Got a credit for one cert, got the nee certs at a great price, and a TEAM of people handled my questions and the activation process and made it painless. Not to mention the validation process for the business was donenin minutes.

You can't beat Digicert!!!!!!!!

Excellent Service and support

I am new to SSL certificates and had a very different configuration and need. Staff were awesome at helping me get the right certificate and get it into the right store. The certificate utility alone is worth the price of the year fee.

DigiCert saved my day

I had to do a demo of my app and of course the previous certificate had expired.
Upon renewal with a well known free certificate authority, I realized the new certificate wasn't accepted by Google Chrome anymore.
DigiCert delivered quickly, support was available and very helpful throughout the (fast) process.
I went from a free certificate to a certificate that works, I don't regret paying for quality.
