HTTP vs HTTPS: Why every website needs HTTPS today

In today’s digital age, securing information online has become more important than ever. One key aspect of online security revolves around the protocols used to transmit data between users and websites. Two such protocols are HTTP and HTTPS. Understanding the difference between HTTP vs HTTPS is crucial for both website owners and users. This blog post delves into the nuances of these protocols, explains why HTTPS is the preferred choice for a secure web experience, and provides comprehensive insights into implementation and best practices.

Understanding HTTP

HTTP stands for HyperText Transfer Protocol. It is the foundation of any data exchange on the Web and is a protocol used for transmitting hypertext. HTTP allows for the fetching of resources, such as HTML documents, and it is the protocol that makes the web work.

When you enter a URL in your browser, it starts with “http://”, which tells the browser to use HTTP to communicate with the web server hosting the website. However, HTTP has a significant drawback: it transmits data in plain text. This means that any data exchanged between the browser and the server can be intercepted and read by anyone who has access to the data stream.

Additionally, HTTP uses a system of status codes to indicate the status of requests made by the client to the server. These HTTP status codes are essential for understanding how web interactions are processed. For example, a “200 OK” status means the request was successful, a “404 Not Found” indicates a missing resource, and a “500 Internal Server Error” points to a problem on the server side.

What is HTTPS?

HTTPS stands for HyperText Transfer Protocol Secure. It is an extension of HTTP and uses a secure connection to encrypt the data being transferred between the browser and the server. The secure connection is established using an SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocol.

When a URL starts with “https://“, it indicates that the website is using HTTPS, and any data exchanged is encrypted. This encryption ensures that even if the data is intercepted, it cannot be read without the decryption key, providing a higher level of security.

HTTP vs HTTPS: Key Differences

Data Encryption

  • HTTP: Transmits data in plain text, making it vulnerable to interception and eavesdropping. Anyone with access to the data stream can read the information being exchanged, which poses a significant security risk.
  • HTTPS: Encrypts data, ensuring that it remains confidential and secure during transmission. Even if the data is intercepted, it cannot be read without the decryption key. This encryption is vital for protecting sensitive information such as login credentials, payment details, and personal data.


  • HTTP: Does not provide any security features. Data can be easily intercepted and manipulated, leading to potential security breaches. This lack of security makes HTTP unsuitable for websites that handle sensitive information.
  • HTTPS: Provides data integrity and authenticity. It ensures that the data sent and received has not been tampered with and that the website is legitimate. This level of security is crucial for maintaining user trust and protecting against various cyber threats, including HTTP flood attacks.

SEO Benefits

  • HTTP: Websites using HTTP do not receive any special ranking benefits from search engines. In fact, search engines may penalize HTTP sites by ranking them lower in search results.
  • HTTPS: Preferred by search engines, improving rankings and visibility. Google and other search engines prioritize HTTPS websites, which can lead to better search engine rankings and increased traffic.

Trust and Credibility

  • HTTP: Users may see warnings in their browsers indicating that the connection is not secure. These warnings can deter users from visiting the site or entering personal information.
  • HTTPS: Websites using HTTPS display a padlock icon in the browser’s address bar, instilling trust and confidence in users. This visual cue reassures users that their data is secure, encouraging them to interact with the website.


  • HTTP: Generally faster because it does not need to establish a secure connection. However, this speed comes at the cost of security.
  • HTTPS: Slightly slower due to the encryption/decryption process, but advancements in technology have minimized this difference. Modern implementations of HTTPS are highly optimized, resulting in negligible performance impacts.

Why to Choose HTTPS Over HTTP?

Protecting Sensitive Information

HTTPS is essential for safeguarding sensitive data such as login credentials, payment details, and personal information. Without encryption, this data is vulnerable to theft. HTTPS ensures that any data exchanged between the user and the website is encrypted and secure from eavesdroppers. This is particularly important for e-commerce sites, online banking, and any platform requiring user authentication. Similarly, for transferring files, secure versions of FTP, like FTPS or SFTP, provide encryption to protect data during transit.

Enhancing User Trust

Users are more likely to trust websites that display a secure connection icon (padlock). This trust is crucial for e-commerce sites and any platform requiring user interaction. When users see the padlock icon, they know that their data is being protected, which increases their confidence in the website. This trust can lead to higher engagement, lower bounce rates, and increased conversions.

Complying with Regulations

Many data protection laws, like GDPR, mandate the use of HTTPS to protect user data. Non-compliance can result in hefty fines and damage to the organization’s reputation. By implementing HTTPS, businesses can ensure they are meeting regulatory requirements and protecting user data from potential breaches.

Additional Benefits

Using HTTPS can also enable the use of newer web technologies that require secure connections, such as HTTP/2 and Progressive Web Apps (PWAs). These technologies can further enhance website performance and user experience. For instance, HTTP/2 can significantly improve loading times by allowing multiple requests to be sent simultaneously over a single connection.

The role of SSL Certificates

SSL certificates are digital certificates that authenticate a website’s identity and enable an encrypted connection. They are critical for implementing HTTPS. SSL certificates are issued by trusted Certificate Authorities (CAs) and come in various types, including Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV).

Using ClouDNS SSL certificates, website owners can easily secure their sites, ensuring data privacy and boosting user confidence. ClouDNS offers a variety of SSL certificates, including Positive SSL, Positive SSL Wildcard, and EV SSL, to meet different needs. These certificates not only provide robust encryption but also display visual security indicators like the padlock icon and, for EV SSL, the organization’s name in the address bar, enhancing trust and credibility.

Additionally, services like HTTP/HTTPS monitoring help maintain the site’s security and performance by alerting owners to potential issues. Monitoring tools can detect anomalies in traffic patterns, identify potential threats, and ensure that SSL certificates are properly configured and up-to-date. By regularly monitoring HTTP and HTTPS traffic, website owners can proactively address security issues and maintain optimal performance.

SSL/TLS Monitoring Explained


In conclusion, the distinction between HTTP and HTTPS is crucial for ensuring the security of online data. While HTTP transmits data in plain text, making it vulnerable to interception, HTTPS encrypts data, ensuring its confidentiality and integrity. This encryption is vital for protecting sensitive information, maintaining user trust, and complying with regulatory requirements. By implementing HTTPS, website owners can significantly enhance their site’s security, boost user confidence, and improve their overall web performance. Understanding the difference between HTTP vs HTTPS and making the switch to HTTPS is a necessary step for any website looking to thrive in today’s digital landscape.
