How TLS Keeps Websites Secure

By DataJive Editorial Team · Updated Oct 27, 2026 · 1 min read

Transport Layer Security (TLS) encrypts the connection between your browser and a website.

What happens when you connect

  1. Your browser asks the site to prove its identity with a certificate.
  2. Both sides agree on encryption settings.
  3. They create temporary shared keys.
  4. Data is encrypted using those keys.

What it protects

Passwords, forms and page content from eavesdroppers and tampering.

What it does not do

It does not verify the site is trustworthy or protect data once it reaches the server.

Key takeaway: TLS secures the connection. Always check you are on the right website too.
