PHP Security Hardening
Harden the PHP app you already run. We review and harden PHP applications: dependency vulnerabilities, unsafe input handling, authentication and session issues, file and server misconfiguration, and a prioritised fix plan you can actually ship.

PHP Security Hardening
What this engagement is for
Most PHP security incidents are not exotic zero-days — they are outdated packages, missing input validation, weak session handling, exposed admin paths, or servers that still run unsupported PHP. We audit the application and its environment, fix what is urgent, and leave you with a clear order of remaining work rather than a scare report with no path forward.

- Best for
- Teams with a live PHP site or app that needs a security review, urgent patches, or ongoing hardening after an upgrade.
- Typical timeline
- 1–4 weeks for an audit and first remediation sprint

Outcomes
What you leave with
We measure the work by the product decisions and assets you can use next — not by a slide deck.
A prioritised list of findings with severity and recommended fixes
Urgent vulnerabilities patched or mitigated
Safer defaults for input handling, auth, sessions, and uploads
Server and PHP configuration hygiene for the environment you run
How we work
A short path from conversation to something real.
- 1
Review
We inspect the codebase, dependencies, auth flows, uploads, and the server configuration that exposes the app.
- 2
Prioritise and fix
Critical and high findings are fixed first. Medium items get a clear next-step plan so the work does not stall.
- 3
Verify
We re-check the fixed paths and hand over what remains, including monitoring and update habits that prevent regressions.
Deliverables
What we produce
- Application and dependency security review
- Remediation of agreed high-priority issues
- Hardening checklist for PHP, web server, and secrets
- Short report your team can continue from
Questions
Before you start
It is an application and environment security review focused on fixable issues in your PHP stack. A formal third-party pentest can follow if you need one for compliance.
Unsupported PHP versions are themselves a security risk. If you are still on 7.4, we usually combine hardening with a version upgrade.
Yes. We start with access and an inventory, then fix what matters most without assuming we wrote the original code.
Code and hosting access, a list of known incidents or worries, and who can approve changes that touch login, payments, or personal data.
