Content Security Policy
Reduce script, object, framing, and mixed-content exposure without breaking the live application.
Bounded website hardening
Close the easy gaps.
Without breaking production.
One agreed security-header repair, implemented and verified for $149. You get the before state, the exact change, browser checks, and rollback notes.
What we can repair
Specific controls. Specific acceptance checks.
Clickjacking protection
Set frame-ancestor controls appropriate for the site’s real embedding requirements.
MIME sniffing
Prevent browsers from treating served files as a different content type.
Referrer policy
Limit unnecessary path and query leakage when visitors leave the site.
Permissions policy
Disable browser capabilities the site does not use, such as camera, microphone, and geolocation.
HTTPS hardening
Verify redirect behavior and HSTS coverage at the application or hosting layer.
What this is not
No fake pentest certificate.
This repair is not a penetration test, compliance certification, breach investigation, vulnerability bounty, or guarantee that a site is secure.
We do not request production passwords, customer data, private keys, recovery codes, or unrestricted cloud access. Broader security work needs a separate written scope and authorization.
Proof on our own production site
The Poszo site serves CSP, HSTS, anti-framing, MIME, referrer, and permissions controls today.
That is capability evidence, not a fabricated client case study. Your repair gets its own before-and-after record based on your stack and real application requirements.
