Differences Between Free and Paid SSL Certificates

Free SSL Certificate: Provides basic encryption but may not be as secure as paid certificates and is more susceptible to man-in-the-middle attacks. The validity period is short, usually 3 months or less, requiring frequent renewal.

Paid SSL Certificate: Goes through a stricter validation process, offering a higher level of protection suitable for websites handling sensitive information. Validity periods are typically 1 year or longer.

Free SSL certificates are suitable for small websites with limited budgets and low security requirements, while paid SSL certificates are ideal for large enterprises, e-commerce websites, or sites handling sensitive information that require higher security, technical support, and trust.

Why Do You Need an SSL Certificate?

Secure Your Website Immediately

By adding an SSL certificate to your website, you can protect all private information shared between you and your visitors from unauthorized users. Additionally, our SSL certificates use 256-bit encryption, which is the industry standard for data protection.

Build Trust

After enabling SSL protection, your website's URL will start with HTTPS, and a lock icon will appear in the address bar. These elements indicate to visitors that your website uses SSL and is safe, assuring them that their credentials and transaction details are secure.

Improve Your SEO Ranking

SSL certificates provide an additional layer of security and add the HTTPS prefix to your site's URL. Search engines consider this an important part of good page experience. This is why Google is more likely to rank SSL-certified websites higher in search results, increasing visibility and organic traffic.

Comply with PCI DSS Standards

Online businesses that receive transactions and handle visitor credentials must comply with PCI security standards, which include SSL protection. Without this security feature, the website puts its visitors at risk and cannot meet regulations.

How SSL Certificates Work

Establishing a Connection

After successfully obtaining or purchasing an SSL certificate, a website receives a public key and a private key. When a user visits the site, their browser requests the SSL certificate and public key to verify its trustworthiness.

Data Encryption

If successful, the browser generates two symmetric keys and sends one of them to the web server using the public key. Upon receiving the key, the server decrypts it using its private key. The browser and server can now form a secure connection to transmit information.

Visual Indicators

A website with a successfully installed SSL certificate will display multiple indicators in the address bar—a lock icon and the HTTPS prefix in the website URL. Depending on the type of certificate, site owners can also display site seals to enhance credibility.

Frequently Asked Questions about SSL Certificates

What is SSL?

SSL (Secure Sockets Layer) or TLS (Transport Layer Security) is a security protocol that enables encrypted communication between a website and a web browser. It prevents unauthorized parties from accessing or viewing data exchanged between the site and its visitors.

SSL certificates are issued by Certificate Authorities (CAs) to websites to verify their identity and inform browsers that the site is secure.

Why Do I Need an SSL Certificate?

In addition to security benefits, SSL certificates enhance brand trust and SEO rankings. This is because they signify good website security practices expected by users and search engines.

SSL certificates are issued by Certificate Authorities (CAs) to websites to verify their identity and inform browsers that the site is secure.

Does My Website Have an SSL Certificate?

To check if your website has an SSL certificate, look for a lock icon and https:// before your domain name in the browser's address bar.

What Types of SSL/TLS Certificates Are There?

There are three types of SSL/TLS certificates based on validation levels.

For Domain Validation (DV) certificates, the Certificate Authority (CA) only requires you to verify domain ownership via email, phone, or DNS records.

Organization Validation (OV) certificates have medium-level validation, so CAs typically check documents verifying the organization's name, contact information, and legal status.

Finally, Extended Validation (EV) certificates provide the highest level of validation, with CAs conducting extensive background checks to verify the registrant's location, legal status, and order details.

SSL certificates can also be distinguished by the number of websites they protect. Single-domain certificates protect one domain and its subdirectories, wildcard certificates cover one domain and multiple subdomains, and multi-domain certificates protect multiple unrelated domains.

Which SSL Certificate Should I Choose?

All types of SSL/TLS protection offer the same encryption level. However, some websites may require certificates with higher validation levels to provide better proof of legitimacy or protect multiple domains simultaneously.

How Long Does It Take for a New SSL Certificate to Take Effect?

Typically, a new SSL certificate takes about thirty minutes to take effect once installed on the website.

How Do I Renew an SSL Certificate?

To manually renew an SSL certificate, you need to generate a new Certificate Signing Request (CSR), fill out the forms, and install the latest version.

Does SSL Help with SEO?

Yes, indeed. Website security is an important ranking factor for Google.

If your website has an SSL certificate protecting it, it has a higher chance of appearing at the top of search results.
