HTTPS is a secure protocol for web communication. It protects user data from interception and tampering.

What is HTTPS?

HTTPS (Hypertext Transfer Protocol Secure) is the standard protocol for encrypted communication between a web browser and a server. Unlike HTTP, HTTPS uses encryption to protect transmitted data, making it unreadable to third parties. It is essential for websites that handle sensitive information such as passwords, personal data, or payment details.

How HTTPS appears in practice?

Examples of when HTTPS plays a critical role:

• Logging into web applications – prevents login credentials from being intercepted.
• Online payments and e-commerce – secures payment data against misuse.
• Submitting forms – protects personal data submitted through contact or registration forms.
• Accessing company apps from the internet – supports secure remote work.
• Ensuring website trustworthiness through a certificate and the padlock icon in the address bar.

Today, HTTPS is a baseline standard. It not only protects your users but also enhances your site's credibility—both in the eyes of visitors and search engines.

How is HTTPS different from similar terms?

• HTTP vs. HTTPS – HTTPS adds encryption via TLS; HTTP sends data unencrypted.
• SSL vs. TLS – SSL is the older encryption technology; modern HTTPS uses TLS.
• HTTPS vs. VPN – HTTPS encrypts the connection between browser and website; VPN encrypts your entire internet traffic.

Understanding these distinctions is important for setting the right security expectations. While HTTPS is essential, it doesn't secure your whole system—only the connection. Without it, even basic form data or login details travel in plaintext and are easy to intercept.

How does the HTTPS in your company?

Recommended steps:

1. Check that all company websites use HTTPS.
2. Obtain and install a trusted TLS certificate from a certificate authority (CA).
3. Set up automatic redirection from HTTP to HTTPS to prevent fallback.
4. Regularly renew and verify certificates for continued protection.
5. Ensure all login forms and sensitive transactions use HTTPS exclusively.

Companies often overlook non-public or “minor” sites when implementing HTTPS. That’s a risk—attackers don’t discriminate by visibility or priority. HTTPS is a fundamental layer of digital security and should be enforced across all web-facing services.
