Benefits of Extended Validation SSL Certificates

Assurance at a Higher Level

One of the primary advantages of EV SSL Certificates is their high confidence level. Unlike Domain Validation (DV) SSL Certificates, which lack identifying information in the organization name field, EV Certificates require thorough verification. This verification encompasses legal rights to the domain, authorization for certificate issuance, physical existence, and alignment with official records. This comprehensive process assures users that they are interacting with a legitimate entity.

Enhancing E-commerce Success with EV SSL Certificates

E-commerce websites thrive on trust and security. In the competitive online shopping landscape, where consumers are cautious about sharing personal and financial information, EV SSL Certificates are pivotal in instilling confidence and driving success. Here’s how they achieve this:

  • EV SSL Certificates display a green address bar in web browsers, instantly assuring online shoppers of a secure and legitimate website. This visible trust indicator reduces the anxiety that leads to cart abandonment, encouraging shoppers to complete their transactions.
  • By providing robust security and building trust, EV certificates create a conducive environment for online shoppers to purchase. When shoppers feel confident about their personal and financial information safety, they are more likely to convert and complete their transactions.
  • EV SSL Certificates distinguish genuine e-commerce websites from fraudulent ones, clearly indicating trustworthiness. This distinction helps build trust with online shoppers, making them more comfortable sharing their sensitive data during checkout, ultimately boosting conversions.

Protection Against Phishing Attacks

In evolving cyber threats, phishing attacks remain a significant concern. EV Certificates play a crucial role in countering phishing attempts. The strict validation standards make it exceedingly difficult for hackers to obtain fake EV Certificates. Here’s how:

  • The EV verification process prevents criminals from obtaining certificates in the target’s name.
  • The prominent green bar indicator in browsers makes fake pages stand out, distinguishing legitimate from fraudulent sites.
  • Even if a phisher somehow obtains an EV certificate, the company’s name on the certificate will not match the legitimate entity, making it instantly suspicious.
