As an experienced internet user, you may recall when manually entering “http://” before each web address was necessary to visit a site.
Now, browsers append this protocol by default, but HTTPS has largely replaced HTTP for enhanced security.
Observe your browser’s address bar displaying “forestvpn.com/blog/“. Upon double-clicking, a padlock icon will appear, indicating the secure “https://” prefix in the URL.
These two indicators confirm that your connection to our site is secure, ensuring the protection of sensitive data like credit card numbers and login credentials.
But what distinguishes HTTP from HTTPS, and why do HTTP sites swap the comforting padlock icon for a “Not Secure” warning? Let’s explore.
What is HTTP?
HTTP, the Hypertext Transfer Protocol, is the foundational protocol used for transmitting web pages over the internet, enabling communication between web browsers and servers.
HTTP, crucial for web navigation, fails to protect personal information due to its lack of encryption. Data transmitted over HTTP is unencrypted plain text, readily intercepted, and deciphered by malicious actors.
Logging into a site via HTTP exposes login credentials to potential eavesdroppers. Consequently, HTTP is increasingly abandoned for HTTPS, which incorporates encryption for enhanced security.
What is HTTPS?
HTTPS, short for HyperText Transfer Protocol Secure, is an internet communication protocol that protects the integrity and confidentiality of data between the user’s computer and the site. Users expect a secure and private online experience when using a website.
We use HTTPS to protect our users’ connections to our website. By ensuring that no one can listen in on conversations, track their activities across multiple pages, or steal their information.
HTTPS helps to prevent these activities by encrypting the exchanged data and authenticating the visited website, safeguarding against man-in-the-middle attacks.
How does HTTPS encryption operate?
Transport Layer Security employs asymmetric encryption to safeguard communication between your browser and the host server, utilizing a pair of keys:
Public key: Accessible to anyone, this key encrypts data from your interactions with the website, which can only be decrypted by the corresponding private key.
Private key: Held exclusively by the website’s owner and stored on the server, this key decrypts information encrypted by the public key.
Before data exchange, an SSL/TLS handshake occurs between your browser and the server to establish a secure connection.
HTTP vs. HTTPS Comparison
HTTPS significantly enhances security compared to HTTP by encrypting the connection between the user’s browser and the server, thereby shielding interaction from potential eavesdroppers such as hackers and ISPs.
Despite the slight latency introduced by encryption, HTTPS typically allows content to load more swiftly than HTTP due to its ability to load multiple page elements concurrently, as opposed to HTTP’s sequential loading.
HTTP has been largely obsolete in favor of HTTPS, with residual use found on some smaller blogs and e-commerce sites. Secure sites, particularly those requiring login and sensitive data submission, invariably employ HTTPS. Users are advised against providing personal details on non-HTTPS sites.
The presence of HTTPS, indicated by a padlock symbol, fosters trust and credibility among users by affirming the site’s commitment to data protection.
Conversely, HTTP sites, often flagged by browsers like Chrome and Firefox for their lack of security, suffer from reduced traffic as users heed these warnings.
For website operators, HTTPS confers a competitive edge in search engine optimization, with Google favoring secure sites in its rankings. The “Not Secure” label that Chrome attaches to HTTP sites effectively deters visitors, emphasizing the importance of HTTPS for website traffic.

FAQ: Understanding HTTP and HTTPS Protocols
Indeed, HTTPS significantly improves website security, but it does not offer an impregnable shield against hacking. There exist numerous other vulnerabilities that cyber attackers can seize, thereby highlighting the fact that HTTPS is merely a single layer of defense within the broader context of website security. Even with the implementation of HTTPS, websites remain susceptible to various forms of sophisticated cyber attacks. These include manipulator-in-the-middle and downgrade attacks, where insidious attackers can deceive your internet browser into connecting to an incorrect endpoint or even force it to revert to the less secure HTTP. Therefore, these potential threats underscore the importance of employing a VPN, even when browsing websites that have adopted HTTPS.
Phishing websites are highly versatile, and it's not uncommon for them to employ HTTPS protocols to deceive users. They exploit the credibility and faith that HTTPS and its padlock emblem insinuate, enthralling users into a deceptive sense of security. Many users fall into believing the website is secure and authentic, oblivious to the fact that it's merely a crafty phishing site intent on pilfering their personal information. Although an HTTPS certificate assures that your activities on the website are encrypted and hidden from third parties, it doesn't provide immunity from the website itself. If the site is malevolent, your sensitive data is still at risk of being usurped.
Absolutely. While HTTPS is indeed a crucial measure to bolster your online security, it does not provide full-proof protection and there remain certain vulnerabilities. Despite the encryption offered by HTTPS, your data can still be intercepted through various means. One such method is via malware installed on your device, which can covertly gain access to your sensitive information. Additionally, firewall rules on a website can be manipulated to redirect your network traffic straight to a malevolent party. This highlights the importance of adopting a comprehensive security approach beyond just relying on HTTPS.
