HTTP vs HTTPS: Understanding the Difference and Why Security Matters

HTTP vs HTTPS: An Overview

If you’ve ever noticed that some websites begin with HTTP while others use HTTPS, you might have wondered about the difference. The main distinction comes down to security.

HTTP (Hypertext Transfer Protocol) is the standard system for transferring data between a browser and a web server, but it does not offer encryption. This means cyber criminals can intercept and modify data.

HTTPS (Hypertext Transfer Protocol Secure) is an upgraded version of HTTP that establishes a secure internet connection via encryption. It uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to protect users’ sensitive information from unauthorised access.

In short, HTTPS is HTTP with encryption and verification, making it far more secure than HTTP.

The Key Difference Between HTTP and HTTPS

1. Encryption for Secure Communication

The most significant difference between HTTP vs HTTPS is encryption.

• HTTP transfers data in plain text, making it vulnerable to attack.
• HTTPS is encrypted and secured using SSL Certificates. It prevents hackers from reading or altering content transferred between a client and a server.

2. SSL/TLS and Security Protocols

• HTTP does not use encryption, leaving websites open to security threats.
• HTTPS relies on SSL (Secure Sockets Layer) or TLS (Transport Layer Security) to protect user data.
• TLS is a newer, more advanced version of SSL, ensuring stronger encryption.
• Websites using HTTPS require an SSL certificate, which verifies the identity of the domain and the web server.

3. Trust and User Confidence

• Users are more likely to trust a website that has a secure connection (HTTPS).
• Websites using HTTPS display a padlock icon in the browser, signalling a trusted and encrypted connection.
• Google marks HTTP pages as Not Secure, which can impact search rankings and user confidence.

4. SEO and Web Traffic Impact

• Google prioritises HTTPS websites in search results, making it essential for SEO and traffic growth.
• A secure protocol improves user experience, reducing bounce rates and increasing sales conversions.

5. Protection Against Cybersecurity Threats

• HTTP is vulnerable to man-in-the-middle attacks, where hackers intercept and alter information.
• HTTPS prevents unauthorised access, protecting data, login credentials, and payment details.
• HTTPS is required for web hosting platforms that handle sensitive user data.

How HTTPS Works: SSL/TLS Encryption

What is an SSL Certificate?

An SSL certificate is a digital certificate that encrypts data transferred between a web server and a browser. It ensures that a public key is used for encryption while a private key decrypts the information on the receiving end.

How HTTPS Establishes a Secure Connection

1. The browser requests a secure connection to the website.
2. The website sends its SSL certificate to verify its identity.
3. A secure connection is made between your web browser and the website.
4. Data is securely transferred between the browser and the website.

Why HTTPS is Essential for E-commerce & Online Services

• Protects user payment data from cyber criminals.
• Required for popular payment gateways like PayPal and Stripe.
• Ensures compliance with industry security standards like PCI-DSS.

How to Upgrade Your Website to HTTPS

1. Obtain an SSL Certificate

• Free SSL: Many web hosting providers offer a Free SSL Certificate.
• Paid SSL: Businesses needing advanced security should opt for Wildcard SSL or EV SSL.

2. Install SSL on Your Web Hosting Platform

• If you are using a Paid SSL, you can install your SSL certificate using cpanel web hosting. Alternatively, you can get a Free SSL Certificate using AutoSSL.
• Redirect all HTTP traffic to HTTPS using .htaccess or server settings.

3. Update Website Links & Content

• Change all internal links from HTTP to HTTPS to avoid mixed content issues.
• Update any third-party integrations (APIs, plugins) that may still use HTTP.

4. Verify the HTTPS Setup

• Check for SSL errors using your browser.
• Use online tools like SSL Labs’ SSL Test to confirm proper encryption.

Free SSL vs Paid SSL: What’s the Difference?

When upgrading your website to HTTPS, one important consideration is whether to use a Free SSL Certificate or invest in a Paid SSL Certificate. Both provide basic encryption, but there are key differences in features, trust, and support:

Free SSL Certificates

• Cost: Completely free and often included with web hosting plans (like VentraIP’s).

• Security: Offers the same level of encryption as paid SSL.

• Validation: Typically Domain Validation (DV) only – confirms ownership of the domain but not the business identity.

• Renewal: Short validity periods (often 90 days), requiring frequent renewal (often automated).

• Support: Limited or no customer support.

• Use Case: Ideal for personal websites, blogs, or small sites without sensitive transactions.

Paid SSL Certificates

• Cost: Comes with a fee based on features and validation level.

• Security: Same strong encryption, with additional trust indicators depending on type.

• Validation: Options include Organisation Validation (OV) and Extended Validation (EV), verifying business identity for higher credibility.

• Trust Indicators: EV SSL may display the company name in the browser address bar, boosting user confidence.

• Warranty & Support: Includes customer support, warranty coverage, and assistance with installation.

• Use Case: This is best for e-commerce sites, larger businesses, or any site handling user data or online payments.

The Bottom Line:
Free SSL certificates are excellent for basic security needs and are suitable for most small websites. Paid SSL certificates are recommended for businesses that require enhanced verification, support, and user trust, especially when handling sensitive customer data or online transactions.

Common Myths About HTTPS

❌ Myth: HTTPS Slows Down Your Website

✅ Reality: HTTPS is optimised for speed, and modern web servers handle encryption efficiently.

❌ Myth: Only E-Commerce Websites Need HTTPS

✅ Reality: All websites benefit from HTTPS, improving security, SEO, and user trust.

❌ Myth: SSL Certificates Are Expensive

✅ Reality: Many web hosting providers offer free SSL certificates to secure your domain.

Final Thoughts: Why You Should Use HTTPS

HTTPS is not just an option, it’s a necessity for modern websites. By switching from HTTP to HTTPS, you:

• Protect user data with secure TLS encryption.
• Improve your Google Search rankings and increase web traffic.
• Gain trust from users and prevent cybersecurity risks.
• Enhance sales by securing online transactions.
