Why every website needs HTTPS
HTTPS should be the default for all websites, not just those that handle sensitive data like credit cards or passwords. Beyond protecting core communications, HTTPS is now a prerequisite for many modern browser features — including service workers, geolocation, and progressive web apps — that open the door to richer web experiences.
HTTPS keeps your site and its content intact
Without HTTPS, the communication between your site and a user's browser is exposed to tampering. The threat isn't limited to malicious attackers: even well-meaning but intrusive third parties, such as ISPs that inject their own ads into pages, can interfere with your content.
Intruders exploit unprotected traffic to redirect users toward malware or phishing pages, or to slip in their own resources. Injected ads can degrade the user experience and potentially introduce security holes.
Every asset traveling between your website and your users—HTML, scripts, cookies, and images—is a potential target. Intrusions can occur anywhere along the network path: on a user's device, at a public Wi-Fi hotspot, or through a compromised ISP. HTTPS raises the bar substantially for anyone trying to intercept or alter that traffic.
Privately protecting your users
HTTPS also prevents passive eavesdropping on the exchange between your site and your users. A common misconception is that only sites handling sensitive communications need this protection. In reality, every unprotected HTTP request carries details that can reveal user behavior and identity.
Individual visits to a plain HTTP site may seem harmless, but across many sites and requests, pattern can emerge. Adversaries can aggregate a user's browsing activity to infer intentions or de-anonymize them. For example, an employee reading unprotected medical articles could inadvertently disclose sensitive health information to an employer analyzing their traffic.
HTTPS is required for new web capabilities
Modern web platform capabilities are being built with HTTPS as a foundational requirement. Features like capturing images or audio via getUserMedia(), offline support through service workers, and progressive web apps all depend on explicit user consent, and HTTPS makes that trust model possible.
Many established APIs are also transitioning to require permission before they execute, such as the Geolocation API. HTTPS is a core part of how browsers handle these permission flows, and as the web evolves, it is simply required to use the features users expect.
