Positive SSL Certificates are regarded as cost-effective certificates and also the fastest to be issued. They also help in encryption of sensitive information but it is a lower bit certificate than the Essential SSL Certificate. It is best for a web service looking to encrypt their information on the web. Comodo comes with 100% online validation and also offers a 30-day refund policy for the certificate along with unlimited re-issuance policy and 99% plus browser compatibility. So while Comodo offers more advanced certificates, Positive SSL Certificates
is still a reliable product. It can secure any type of site with its automated validation.
