Benefits of using Sectigo SSL for your website

Before making purchases, accessing accounts, or sharing sensitive information, site visitors seek known indicators of secure connections, including the padlock icon, https in the address line, and the color green.

To further improve transaction rates, consider adding additional security indicators such as your company brand name to the address bar by installing Extended Validation (EV) certificates on your site. Research shows that visitors displaying the company-branded EV address bar are more likely to complete transactions including purchases, sharing personal information, and signing up for new services. They also are more inclined to associate positive qualities like high levels of customer service, stability, and trustworthiness with companies displaying the branded address bar.

Google Chrome and Firefox both require that all web pages be encrypted by SSL regardless of whether or not transactions take place on them or the type of content served. Any page not under https will automatically receive a “Not secure” warning at the top of the browser interface. The only way to prevent these warnings is for all pages in your site to be protected by SSL.

Popular search engines improve the search rankings of SSL-enabled pages algorithmically. That makes it an easy and inexpensive way to improve SEO performance.

Many important regulatory and industry standards require that online businesses protect personally identifiable information (PII), personal health information (PHI), credit card numbers, and other sensitive data. Failure to do so can result in fines, loss of privileges, and other non-compliance penalties.

All Sectigo TLS certificates enable 256-bit encryption, the strongest encryption available for web connections.

What are SSL certificates?

SSL (Secure Sockets Layer) is the popular name for Transport Layer Security (TLS), a standard security protocol that establishes encrypted links between a web server and a browser, ensuring that all communication that occurs between them remains encrypted and therefore private. Millions of websites use SSL to protect credit card numbers, data transfer, login pages, and browsing on websites of all sorts, including blogs and social media sites. Not only does enabling HTTPS on websites provide consumer trust that the website is legitimate and is safe for browsing and transactions, but it has now been mandated by leading browsers such as Google Chrome. Websites without SSL display a ‘Not secure’ warning in Chrome’s address bar.

The growth of global websites, mobile, and internet connected devices has also expanded the use of SSL well beyond just ecommerce. Anyone who needs to securely share data between devices over the internet requires one of these digital certificates. Common uses include

  • Online credit card transactions
  • Web forms and customer logins
  • Email servers and webmail applications
  • Corporate communication through intranets, file sharing, extranets, and internal servers
  • Cloud based platforms and virtualized applications
  • File transfer over ftp
  • Data transfer to and from mobile devices

Types of SSL Certificates

There are many different type of certificate options available, all with their own unique use cases and value propositions. The level of authentication assured by the CA is a significant differentiator between them. Sectigo’s full range of certificate options include:

Extended Validation (EV) Certificates

The highest level of protection offered for TLS, Extended Validation (EV) is the industry standard for business web sites. When an EV SSL certificate is loaded on a site, popular browsers such as Safari and Microsoft Edge will display additional trust indicators, including the company name in a green browser address bar. Commonly referred to as the “green address bar” or “branded address bar,” this interface element tells users they are interacting with the intended online business and not a scamming impostor.

Organization Validation (OV) Certificates

Organization Validated (OV) SSL certificates are a simpler, faster certificate option for registered organizations. To receive an OV certificate, the company must prove it owns the domain it is seeking to secure and prove it is a legally registered business. Through visual trust indicators — like the appearance of HTTPS, the padlock icon, and dynamic site seal — visitors will know the site is trusted and secured.. Know More

Domain Validation (DV) Certificates

Domain Validated (DV) SSL certificates provide the quickest, easiest, and most cost effective way to receive industry-standard encryption. To attain a DV certificate, companies must prove ownership of the domain being secured. Know More

Wildcard Certificates

Many websites have multiple sub domains under their main domain. One wildcard certificate can be used to secure the main domain and an unlimited number of sub-domains under the main domain. Know More

Multi-Domain/UCC/SAN Certificates

Multi-domain certificates may also be called a SAN certificates or UCC certificates but they all the same purpose: Each is a single certificate that secures multiple domains.. Know More
