Follow this ultimate guide to equip your website with trusted SSL encryption.

What is an SSL Certificate?


An SSL certificate is a digital certificate that encrypts the data transmitted between a web server and a web browser. 

Installing an SSL certificate enables HTTPS and establishes secure connections. An Enterprise SSL Certificate Management solution helps centralize and automate SSL deployments, renewals, and installations for enterprises managing multiple websites and domains. 

It provides visibility into all certificates from one dashboard to monitor issues and ensure continuous compliance. Enterprise SSL certificate management platforms streamline security operations for IT teams overseeing complex multi-server web environments.

Why Do You Need an SSL Certificate?

There are several important reasons why every website needs an SSL certificate:

  • Encrypt Sensitive Data – SSL encryption protects sensitive information like credit card numbers, login credentials, and personal data entered on your website forms.
  • Establish Trust – An SSL certificate verifies the identity of a business and its website. It shows visitors that the site is secure and legitimate.
  • PCI Compliance– If the website accepts credit card payments, it must have an SSL certificate in place for PCI-DSS compliance. This is the standard for businesses processing card data.
  • Improved Google Rankings – Google prefers HTTPS sites with SSL certificates over unsecured HTTP websites in search results.
  • Avoid Browser Warnings – Visitors will encounter security warnings when a site does not have HTTPS. To convert to HTTPS and evade these alerts, an SSL certificate is needed.
  • Comply with Industry Regulations – SSL certificates are necessary for businesses like banks and hospitals to abide by industry standards and regulations of security.
  • Future-Proof Website – Data breaches and hacking attacks are rising. Having an SSL certificate ensures your website provides the latest encryption standard and remains secure.

Types of SSL Certificates


There are different types of SSL certificates available based on validation levels, which are:

1. Domain Validated (DV) SSL Certificate

This is an entry-level and affordable SSL certificate that provides standard HTTPS encryption. Domain validation simply verifies that you own or control the domain name. Business identity verification needs to be done. DV certificates are issued within minutes and are ideal for personal websites and blogs.

2. Extended Validation (EV) SSL Certificate

This offers the highest level of validation. EV SSL certificates clearly display your company or organization name in the browser address bar. The CA runs thorough background checks to vet your business’ legal, operational, and physical existence. EV certificates establish maximum trust but are also more expensive.

3. Wildcard SSL Certificate

This certificate secures unlimited subdomains on your website using a single certificate. It supports and any other second-level domains. It is ideal for large websites and multiple domains managed through one account.

4. Multi-Domain SSL Certificate 

This means that one certificate can secure different domain names, up to 100 domains. Good for managing numerous small websites with a single SSL certificate.

How to Get an SSL Certificate


Here are a few steps to follow while getting an SSL certificate for your website:

  • Choose Certificate Type – You should select the right certificate type depending on your requirements and budget, e.g., DV, OV, EV, Wildcard and so forth.
  • Pick SSL Provider – Find a CA which is respectable that offers certificates at low prices.
  • Do CSR – A file with your site’s public key required for getting a certificate must be created on your web server.
  • Send Verification Documents – Afterwards, you will receive an email from them asking for some evidences of domain ownership and the CSR. This takes place when verifying authentication.
  • Get a Certificate from SSL Provider– The certification authority verifies information and issues an SSL certificate in a couple of hours or days.

Best Practices for SSL Certificate Implementation  


For more security when creating new SSL certificates, these principles are important:

  • Opting for the Right Certificate Type – In places where sensitive transactions occur (e-commerce), use OV or EV certificates. Or else choose Wildcard ones if you have multiple subdomains on one or more domains.
  • Use Strong Keys – To increase protection, use keys of at least 2048-bit strength.
  • Create Trust – Enhance credibility by displaying trust seals in public, advertise business details through HTTPS URLs.
  • Take away the Old Protocols – Safeguard against potential vulnerabilities by not using legacy SSL protocols such as TLS 1.0 and 1.1 on your site.
  • Act before it is Too Late – Set up automated reminders to alert you when it’s time to renew the certificate, preventing service disruptions.
  • Secure All Your Website– Put rules in place that will redirect all pages and assets on this domain to HTTPS.
  • Watch for Threats– Take advantage of malware scanners, web application firewalls etc., what should be done.


Nowadays, it is important to install and manage the SSL certificates well. It helps encrypt sensitive information, instill confidence in visitors, and keep online transactions safe amidst today’s increasingly dangerous digital landscape. 

Website owners can, therefore, implement robust SSL protection that will secure their data against threats even in the future by following this ultimate guide.
