The Sectigo (formerly Comodo CA) PositiveSSL is one of the most popular certificates used to verify domains. This 2048-bit product conforms to the industry standard and supports SHA and ECC hash algorithms, while the price is relatively low.
The distinguishing feature of PositiveSSL is the lock icon in the address bar. Customers can see that the information is encrypted and inaccessible to third parties, and that its confidentiality is maintained by a trusted SSL certificate. It is difficult to find a more suitable SSL for small internet projects and startups.
There are no problems with documents. The domain ownership verification process is automatic and takes five to ten minutes. After that, you can get the SSL and install it on the web server, also spending just a few minutes. This is an economically effective way to maintain the desired level of trust. The advantages of the certificate are that you can protect not only WWW domains, but also others, and that you can install SSL on any desired number of servers.
Among all browsers and mobile products on the market, 99.6% have the required level of equipment thanks to Sectigo CA. Products with lower functionality from other manufacturers are often more expensive.
