Why Do You Need an SSL Certificate?
Secure Your Site
SSL certificates encrypt the connection between your website and your visitors, protecting sensitive data like logins, forms, and payments. This helps prevent man-in-the-middle attacks, data leaks, and other malicious activities.
Build Customer Trust
Visitors are more likely to trust a site with the padlock icon and HTTPS prefix. SSL signals that your site takes security seriously. Essential for ecommerce, login portals, or any site handling personal information.
Boost Your SEO
Search engines like Google favor secure sites. Enabling HTTPS by installing an SSL certificate can give your site an edge in rankings, increase click-through rates, and ensure your site is flagged as “safe” in modern browsers.

Hosting Option?
Yes, sometimes it's easier to implement multiple certificates instead of one master certificate designed to fit all occasions. Typically this includes cases of sites that serve up their content without a www. prefix, or those with multiple domains and subdomains requiring SSL coverage.
EssentialSSL is simply PositiveSSL with a few upgrades. With an EssentialSSL certificate, you can get free EV upgrade, free 24/7 technical support and most importantly to many, you get the free use of the Site Seal which is a key trust signal for those who are shopping at your site.
PositiveSSL certs are inexpensive Domain Validation SSL certificates which are issued instantly and cheaply, and include $10,000 Comodo warranty (mostly because they can be validated automatically. InstantSSL certificates use Organization Validation, take much longer to be issued, cost more, and have $50,000 Comodo warranty.
Regular SSL certificates protects a single domain, period. Wildcard certificates protect a domain and all the subdomains associated with that domain. Keep in mind that the wildcard certs are not available with Extended Validation. So, if you have a wildcard cert, you won't get the green browser bar!
If an SSL certificate expires, browsers will show security warnings and block users from accessing your site. This can lead to lost traffic, broken trust, and even SEO penalties. It’s important to renew your SSL before it lapses to keep your site secure and accessible.
Modern SSL implementations are designed to be fast and efficient. In most cases, users won’t notice any difference in site speed. In fact, HTTPS enables the use of HTTP/2, which can improve load times for well-optimized websites.
Yes, a Multi-Domain SSL certificate (also called SAN certificate) allows you to secure several domains or subdomains under a single certificate. This makes it easier to manage and is ideal for businesses with multiple web properties.
Free SSL certificates like Let’s Encrypt offer basic encryption, but they lack warranties and advanced validation. For ecommerce or professional websites, paid certificates provide stronger trust signals, validation levels, and support — all critical for brand credibility.
SSL certificates come in three main validation types: Domain Validation (DV) Organization Validation (OV) Extended Validation (EV) DV verifies domain ownership and is issued quickly. OV adds business identity verification. EV provides the highest level of assurance, displaying the company name in the address bar for maximum trust.
Up to 250 domains, IP's or SAN's can be covered by a single multi-domain SSL certificate. They aren't cheap, but they do give umbrella coverage to an organization which has many domains and would otherwise need multiple single-domain certificates.
