This is the lowest level of authentication used to issue SSL certificates. The Certificate Authority (CA) will issue this certificate to anyone listed as the domain admin contact in the public record associated with a domain name. As a result, DV certificates are issued very quickly. No company information is checked or displayed on the certificate, making it easier for criminals to gain this type of certificate from irresponsible CAs.
WHEN TO USE DV
Situations where trust and credibility are less important
Easy to obtain.
Use only for web-based applications that are not at risk for phishing or fraud.
Don’t use for public facing sites or sites that handle sensitive data, like log ins.
OV is the more secure step up from DV. As well as checking up on ownership of the domain name, the CA will also carry out additional vetting of the organisation and individual applying for the certificate. This might include checking the address where the company is registered and the name of a specific contact. This vetted company information is displayed to visitors on the certificate, making ownership of the site much more visible.
WHEN TO USE OV
Public-facing websites dealing with less sensitive transactions
More thorough vetting process than DV.
Company information is displayed to users.
Provides a certain level of trust about the company who owns the website.
Doesn’t offer the highest visible display of trust like EV SSL (green browser bar).
This is the gold standard in SSL certificates.
EV verification guidelines, drawn up by the CA/ Browser Forum, require the CA to run a much more rigorous identity check on the organisation or individual applying for the certificate. Sites with an EV SSL certificate have a green browser address bar and a field appears with the name of the legitimate website owner and the name of the CA that issued the certificate.
WHEN TO USE EV
E-commerce sites and websites handling credit card and other sensitive data
Use EV SSL for the highest visible display of online trust.
Comes with the green browser address bar.
Increase user trust and lower bounce rates.
Strengthen your credibility and brand by showcasing your commitment to online security.
