A primera vista, parece una pequeña diferencia, una sola letra, pero esa pequeña "s" tiene un peso significativo. It signals whether your connection is secure or exposed, and in today's digital world, that distinction matters more than ever.  #### Jump to a Section 1.

Es la forma básica en la que los sitios web solían enviar y recibir información. Usa algo llamado puerto 80, que es como una "puerta" en tu computadora que permite la conexión con los sitios web. But with HTTP, the data goes through that door unprotected, so others can see or steal it. ### How HTTP works When you enter a website address, your browser sends a request to the server. El servidor responde con el contenido (como una página HTML). Everything in this request and response can be seen by anyone monitoring the connection. ### Risks of HTTP Login details, payment data, and personal messages can be intercepted. This is why browsers now flag HTTP sites as "Not Secure." ### Why HTTP is still used Some old systems or internal company tools still use HTTP because they were built that way and haven't been updated. Pero en la conexión de Internet pública, el uso del HTTP es poco frecuente y seguro, ya que deja tus datos expuestos. It's kind of like locking your front door with tape instead of a key. ## __What is HTTPS?__ HTTPS stands for Hypertext Transfer Protocol Secure. Es el mismo protocolo que el HTTP pero tiene capas de TLS (seguridad de la capa de transporte). This ensures that the communication is encrypted and authenticated. ### How HTTPS works - The browser connects to a server using port 443, a door reserved for secure, encrypted communication. - The server presents a digital certificate from a trusted Certificate Authority. - The browser verifies the certificate, and the two exchange encryption keys. - All further communication is encrypted, keeping outsiders from eavesdropping. ## 4 Benefits of HTTPS 1. Keeps your info safer - things like passwords, credit cards, and messages are __encrypted__, so they're harder for hackers to steal. 2. Confirms who you're talking to - HTTPS helps you know you're really on the right website, not a fake one pretending to be it. 3. Shows trust signs - most browsers show a padlock icon when a site uses HTTPS, which tells you it's using a secure connection. 4. Follows the rules - it helps websites meet legal requirements like __PCI DSS__ (for online payments) and __GDPR__ (for user privacy). __But remember:__ HTTPS doesn't make a site completely safe. Protege la conexión, no el contenido. A scam site can still use HTTPS - and mimic the padlock - so always be careful where you click and what you share. __*Tip*: Click the padlock icon in the browser's address bar to see the site's certificate details. Legitimate businesses usually have verified certificates that show their name, while scammers often use basic certificates with little info.__ ## __Why HTTPS matters__: 3 reasons ### 1. __Security and privacy__ HTTPS protects your data as it travels between your device and a website. Esto es especialmente importante en conexiones wifi públicas (como una cafetería), donde los atacantes pueden intentar interceptar tu conexión. Por ejemplo, si ingresas a tu email con el HTTP, tu nombre de usuario y contraseña son enviados en texto simple y cualquiera que esté mirando la red podría robarlos. Con el HTTPS, esa información está codificada, por eso otros no pueden leerla. HTTPS also helps prevent man-in-the-middle (MITM) attacks, where someone secretly alters or "listens" to the communication between you and the website. ### 2. __Performance advantages__ In the past, encrypting data (like HTTPS does) made websites slower. But now, with new improvements, HTTPS is often faster than HTTP. - __HTTP/2__ lets websites send many requests at once over a single connection, so pages load quicker. - __HTTP/3__ uses a new technology that helps websites load faster, especially on phones and shaky internet connections. In other words, HTTPS doesn't just protect - it can actually improve site performance. ### 3. __SEO and user trust__ If you run a small business or have a website, HTTPS helps your site show up higher on Google, bringing more visitors. También hace que tu sitio se vea confiable: los visitantes se sienten seguros para compartir su información. Even if you're just sharing a blog or personal site, HTTPS helps protect you and your visitors from hackers and keeps your connection more private. ## __What happens when a site isn't secure?__ On an HTTP site: - Your data is sent without encryption (in plain text). - Attackers can "listen in" by spying on Wi-Fi, redirecting traffic, or capturing data. - Hackers can inject malicious code, like unwanted pop-ups or redirects to fake websites. - Browsers may warn you or even block the site altogether. The takeaway: __never enter sensitive information on an HTTP site.__ ## __Migrating to HTTPS: Best practices__ For most small business owners, bloggers, or casual content creators - website builders and hosting providers usually handle HTTPS for you automatically. So, if you're using a popular website builder or host, you probably don't need to worry about most of the technical steps, it's done behind the scenes. ## __9 FAQs about HTTP vs. HTTPS__ 1. __Is HTTPS really safer than HTTP?__ Yes. HTTPS encrypts the data sent between your browser and the website, while HTTP sends data in plain text that anyone can read. 2. __Can HTTPS stop all cyberattacks?__  No. HTTPS helps protect against data interception but does not prevent all threats like malware, phishing, or weak passwords. 3. __Does HTTPS slow down websites?__  No. With modern technologies like HTTP/2 and HTTP/3, HTTPS sites often load faster than HTTP sites. 4. __Why do some sites still use HTTP?__  Mostly because of older systems, cost concerns, or simply because the site owners haven’t updated their setup. 5. __Is HTTPS free?__  Some services provide free SSL/TLS certificates. 6. __Do all websites need HTTPS?__  Yes. It protects visitors and helps improve search engine rankings. 7. __How can I tell if a site uses HTTPS?__ Look for a padlock icon and __https://__ at the start of the web address. Haz clic en el candado para verificar la información de seguridad. 8. __Can HTTPS improve SEO rankings?__  Yes. Google uses HTTPS as a ranking factor and trusted sites tend to keep visitors longer. 9. __What happens if my certificate expires?__ Your visitors will see a warning that the certificate is expired, which can scare them away from your site. ## __Key takeaways on HTTP vs. HTTPS__ HTTPS isn't just an upgrade - it's the __standard for a secure and trustworthy web__. Ya sea que estés navegando por Internet o administrando sitios web, el HTTPS te permite proteger tu información personal, le da mayor velocidad a tu experiencia y genera confianza entre tú y los sitios que visitas (o los sitios que manejas). Using HTTPS is a simple but powerful step to keep everyone safer online. ##### __You may also be interested in:__ - [Wi-Fi Security: Essential Protections for Your Home Wi-Fi](https://www.t-mobile.com/home-internet/the-signal/speed/wi-fi-security-essential-protections) - [What is a Firewall and What Does It Do?](https://www.t-mobile.com/home-internet/the-signal/internet-help/what-is-a-firewall) - [5 Next-Level Security Wi-Fi Tips for Home](https://www.t-mobile.com/home-internet/the-signal/internet-help/5-next-level-security-wi-fi-tips-for-home) - [Security And Wi-Fi: How Does A VPN Work?](https://www.t-mobile.com/home-internet/the-signal/internet-help/security-and-wifi-how-does-a-vpn-work) - [101 Guide To Wi-Fi Subnet Masking Networks](https://www.t-mobile.com/home-internet/the-signal/internet-help/guide-to-wifi-subnet-masking-networks) Sources: - [https://aws.amazon.com/compare/the-difference-between-https-and-http/](https://aws.amazon.com/compare/the-difference-between-https-and-http/) - [https://www.cloudflare.com/learning/ssl/why-use-https/](https://www.cloudflare.com/learning/ssl/why-use-https/) - [https://www.cnet.com/tech/services-and-software/http-a-barrier-to-web-services/](https://www.cnet.com/tech/services-and-software/http-a-barrier-to-web-services/) - [https://simtechdev.com/blog/complete-guide-how-to-migrate-from-http-to-https-without-traffic-loss/](https://simtechdev.com/blog/complete-guide-how-to-migrate-from-http-to-https-without-traffic-loss/) - [https://www.shopify.com/blog/http-to-https](https://www.shopify.com/blog/http-to-https) - [https://support.wix.com/en/article/about-ssl-and-https](https://support.wix.com/en/article/about-ssl-and-https) - [https://www.cbtnuggets.com/common-ports/what-is-port-80](https://www.cbtnuggets.com/common-ports/what-is-port-80) - [https://www.cloudflare.com/learning/ssl/transport-layer-security-tls/](https://www.cloudflare.com/learning/ssl/transport-layer-security-tls/) - [https://www.identityguard.com/news/how-to-tell-if-a-website-is-fake](https://www.identityguard.com/news/how-to-tell-if-a-website-is-fake) Tags - [Security](https://www.t-mobile.com/home-internet/the-signal/archive/security) - [Technology](https://www.t-mobile.com/home-internet/the-signal/archive/technology) ## Related Articles NEW [Read More](https://www.t-mobile.com/home-internet/the-signal/speed/ethernet-vs-wifi) [](https://www.t-mobile.com/home-internet/the-signal/speed/ethernet-vs-wifi) [Speed](https://www.t-mobile.com/home-internet/the-signal/category/speed) ## [Ethernet vs. Wi-Fi: Which Connection is Best for You?](https://www.t-mobile.com/home-internet/the-signal/speed/ethernet-vs-wifi) April 29, 2026 NEW [Read More](https://www.t-mobile.com/home-internet/the-signal/internet-connection/how-does-the-internet-work) [](https://www.t-mobile.com/home-internet/the-signal/internet-connection/how-does-the-internet-work) [Internet Connection](https://www.t-mobile.com/home-internet/the-signal/category/internet-connection) ## [How Does the Internet Work?
