What is an SSL certificate?

SSL, or Secure Sockets Layer, is a data security tool that was designed to keep communication over the internet safe. Data sent via an SSL connection is protected by a mechanism called encryption that scrambles the data in transit to prevent theft and tampering. All SSL provide same encryption, however mechanisms of obtaining a certificate varies by type a.k.a validation type

Difference between types

  • Domain validation SSL (DV)
    DV SSL are considered to be of low assurance and are the easiest to get—all you need to confirm is that you own the domain you apply for the SSL with. This validation method is secure enough, however if someone obtains control over a domain they don’t own, (i.e. email access, ftp access or DNS access), SSL could be issued to a wrong person. Great for personal user, facebook app or login page.
  • Extended validation SSL (EV)
    EV SSL are the most hacker-proof certs in the industry thus are considered as the most trusted. For you to obtain EV, company's legal existence, operation history and physical existence must be confirmed. These kinds of certs are impossible to fake, that’s why they get “very high assurance” grade. Also they are the only type of certs that turn your browser's address bar green—commonly recognized as a “safe” color—to indicate secure connection, displaying your business name clearly to show that you’re a legitimate host company.
  • Organization validation SSL (OV)
    OV SSL also require organization legal existence confirmation, however organization validation process requires less steps, i.e. it doesn’t matter how long a company operates, certificate authority doesn’t verify the person who applies for OV on behalf of a company, neither legal address is verified via public sources. Also, OV certificates looks the same as DV certs in browser. The fact that it’s organization, not domain validation cert can be checked in certificate details in browser if a visitor actually knows the difference and is curious enough

What to choose?

OV and EV are recommended for business, DV — for individuals. To be honest, EV are not that more expensive than OV, but show a visual difference to a site visitor. Though HTTPS indicates a secure URL, people often need visual reinforcement. EV SSL is especially recommended for ecommerce sites as building confidence among customers and forming a trustworthy reputation around the site and brand is essential for such type of business

Go all-HTTPS

Did you know that google rewards all-HTTPS sites increasing their search engine ranking?In August 2014, Google announced that the ranking position of a website can be increased by using an SSL certificate. Not to mention encrypted connection protects privacy on the internet
