Eliminate web browser security warnings Eliminate web browser security warnings Google Chrome and Firefox strongly encourage securing all web pages with SSL/TLS. Even if your site doesn’t handle transactions or sensitive data, these browsers will display a “Not secure” warning for any page served over HTTP. The only way to prevent these warnings is for all pages on your site to be protected by SSL. Improve SEO ranking

Have another question? Reach us by chat in the lower-right corner. What is an SSL certificate? An SSL certificate provides a way to authenticate the identity and secure connections for a website. The TLS (Transport Layer Security) protocol—often still referred to by its older name, SSL (Secure Sockets Layer)—enables encrypted communications between two machines, and an SSL certificate is a small data file leveraging this security protocol to complete the following functions: Authentication – SSL certificates serve as credentials to authenticate the identity of a website. The validation level depends on the type of certificate purchased. Secure data communication – When installed on a web server, an SSL activates the HTTPS protocol and creates a secure connection between the server and a browser. The padlock icon will also appear in the web browser. Certificate issuance from a trusted CA, like Sectigo, will be recognized by browsers as legitimate and will enable the security indicators in the browser. Which validation type should you buy? The type of domain or domains you’re trying to secure will determine if you need an EV, OV, or DV SSL certificate. Domain Validation SSL certificates DVs provide the fastest and cheapest way to secure a website. The validation process only requires proof of domain name ownership. The simplicity of this process allows these SSL certificates to be issued in minutes. This type works best for domains that don’t need to establish site visitor trust such as internal sites, test servers, and test domains. Organization Validation SSL certificates An OV SSL certificate provides the same level of protection as a DV certificate but shows that the individual or organization has been validated by a CA. To obtain an OV certificate, proof of domain ownership must be provided and a CA must confirm the legitimacy of the business or organization associated with the domain. Company name, address, and other details must be confirmed before issuance is completed. An OV SSL works for public-facing websites but is not recommended for those requesting sensitive information. Extended Validation SSL certificates EV certificates provide the highest level of trust due to the strict validation process that must be completed before issuance. Once company details are confirmed, a human specialist will perform the last steps in the vetting process. This is the preferred SSL type for websites that request personal information and is the industry standard for eCommerce websites. How do you buy an SSL certificate? Once you’ve chosen the type of SSL certificate you need, the online purchase process with Sectigo is simple. Add your certificate to the cart and create a new account or log in to your existing account. From there, you’ll be able to complete the checkout process and we will provide you with detailed next steps on issuance depending on the level of validation selected. This will take anywhere from a few minutes to a few days after all required documents are received, depending on the type. How much does an SSL certificate cost? An SSL certificate issued from Sectigo, a leading Certificate Authority, starts at $110 for a one year single domain DV SSL. Pricing varies from there, depending on the validation level, how many domains are being secured, and the subscription plan chosen.
