HTTP vs HTTPS! Advantages and Disadvatages

You will know the importance of NON HTTPS vs HTTPS website. Some of them you didn’t hear before!

First of all, we need to differentiate HTTP and HTTPS.

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. While Hyper Text Transfer Protocol Secure (HTTPS) is the SECURE version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The ‘S’ at the end of HTTPS stands for ‘Secure’. It means all communications between your browser and the website are encrypted.


HTTP Advantages

  • Platform Independent which allows straight cross-platform porting.
  • No Runtime support required to run properly.
  • Usable over Firewalls means global application possible.
  • Not Connection-Oriented, meaning no network overhead to create and maintain session state and information.

HTTP Disadvantages or Limitations

  • Insecure data or information in many aspects.
  • In terms of Privacy, anyone can see your content.
  • In terms of Integrity, someone might alter your content because no encryption methods are used.
  • In terms of Authentication not clear who you are taking with. If someone intercepts the request can determine the username and password being used.
  • Stateless means need State Management Techniques to maintain the information across multiple request-response cycles.

HTTPS Advantages

  • Makes HTTPS secure by the used of Secure Sockets Layer (SSL) acts like sub layer under regular HTTP application layering.
  • In Privacy, data is encrypted so nobody can listen to conversation and track activities of users while they are browsing the Internet.
  • In Integrity, data cannot be modified during transfer without being detected.
  • In Authentication, proves that your users communicate with the intended website. It protects against man-in-the-middle attacks and builds user trust, which translates into other business benefits.
  • Ability to connect to a server via HTTP secure.
  • HTTPS website will rank your website higher on local search results.

HTTPS Disadvantages or Limitations

  • HTTPS server can only provide one “virtual host” behind a single socket, as opposed to multiple one behind an HTTP socket. This is because all security negotiation takes place before the HTTP proti\ocol starts & hence before the server knows which URL the client is asking for.
  • HTTPS cannot prevent stealing confidential information from the page cached on the browser. Since in SSL data encrypted only during transmission on the network, it is in clear text in the browser memory.
  • HTTPS is slightly slower than HTTP website because it adds computational overhead as well as network overhead.




For me, the winner is HTTPS because in terms of security and search results ranking. I recommend to you that you NEED HTTPS over SSL if your website does the following:

  • Online store that accepts online orders and credit cards.
  • Have login or registration form.
  • Process sensitive data such as address, birth date, ID number and others.
  • A blog site to rank your website in search results.
  • Have the budget to accommodate SSL.
