How to Secure Your Website in 2026
A practical checklist for TLS, headers, auth, and monitoring — without slowing down releases.

Transport and headers
Use modern TLS, redirect HTTP to HTTPS, and set strict security headers (CSP where feasible, HSTS on apex and www).
Authentication and sessions
Prefer established identity providers, short session lifetimes, and secure cookie flags. Rate-limit login and reset flows.
Dependencies and build pipeline
Scan for vulnerable libraries in CI. Block merges on critical issues unless explicitly waived with ownership.
Server and runtime hardening
Remove unused services, segment networks, and restrict admin access. Use infrastructure-as-code so drift is visible.
Monitoring and logging
Centralise logs with retention that matches your sector. Alert on auth spikes, 5xx bursts, and admin actions.
Regular testing
Combine automated scanning with periodic manual review of high-risk flows — checkout, account recovery, file upload.
