If you build and maintain sites for clients, you are on the hook for security on properties you may not log into for weeks. A header gets dropped in a redesign, a certificate lapses, a staging subdomain is left exposed. The client will not catch it. You are expected to.
Here is a simple, repeatable workflow that keeps that under control without it becoming a full-time job.
Step 1: baseline every client site
Scan each client domain once and note the score. You will usually find the same quick wins across a portfolio: missing security headers, a weak or missing Content-Security-Policy, no HSTS, and email records like DMARC and SPF that were never set. Knocking those out is fast and moves the score immediately.
A free scan at scorifya.com gives you a 0 to 100 hardening score plus the specific fix for each finding (TLS, headers, DNS and email, cookies, exposure), with no signup needed to run it.
