Close critical PHP vulnerabilities before attackers find them.

Rapid assessment, patching and secure upgrades for PHP applications exposed by newly disclosed vulnerabilities, unsupported PHP versions and ageing code, combining AI-assisted code analysis with expert security engineers.

Overview

PHP Security & Vulnerability Remediation

PHP still powers a large share of the web, including customer portals, payment and loan applications, internal tools and websites at banks, insurers and other regulated organisations. Many of these systems run on PHP versions that no longer receive security fixes, depend on outdated frameworks and plugins, or contain code written years ago by people who have since moved on.

When a critical PHP vulnerability is disclosed, attackers scan the internet for exposed systems within hours. Organisations that cannot quickly answer “are we affected, and where?” are the ones that end up in incident reports. For financial institutions, the consequences extend to regulatory scrutiny, customer trust and operational resilience obligations.

We help you respond fast and fix properly. Our engineers use AI-assisted code analysis alongside proven static analysis and manual review to find vulnerable code quickly, contain the immediate risk, and then remediate the root cause: upgrading PHP, updating dependencies, fixing insecure code and hardening servers, with full testing so nothing breaks in production.

Problems we solve

  • Internet-facing PHP applications running versions that no longer receive security patches
  • A newly disclosed critical vulnerability and no clear view of which systems are affected
  • Legacy PHP code with SQL injection, file inclusion or authentication weaknesses
  • Outdated frameworks, Composer packages and CMS plugins with known vulnerabilities
  • Audit, APRA or penetration-test findings that need to be closed against a deadline
  • Fear that upgrading PHP will break critical business systems

What’s included

A complete engagement, end to end.

01

Rapid exposure assessment

An inventory of your PHP applications, versions, frameworks and plugins, checked against newly disclosed vulnerabilities to show exactly where you are exposed.

02

Emergency patching & hotfixes

Prioritised fixes for critical vulnerabilities, deployed with tested rollback plans and minimal disruption to customers.

03

Virtual patching & WAF rules

Immediate protection through web application firewall rules while permanent fixes are developed, tested and released.

04

PHP version upgrades

Safe migration from unsupported PHP 5, 7 and early 8 releases to currently supported PHP 8 versions, using automated refactoring and regression testing.

05

Dependency & framework updates

Updates to Composer packages, Laravel, Symfony, WordPress, Drupal and custom libraries, with breaking changes resolved and tested.

06

AI-assisted secure code review

AI code analysis, static analysis tools and expert review combined to find SQL injection, cross-site scripting, insecure deserialisation, file inclusion and authentication flaws.

07

Server & configuration hardening

Secure php.ini, PHP-FPM and web server configuration, disabled dangerous functions, least-privilege permissions and secrets management.

08

Penetration & regression testing

Independent security testing before and after remediation, plus automated tests that confirm business functionality still works.

09

Continuous vulnerability monitoring

Automated alerts for new PHP and dependency vulnerabilities, security scanning in your deployment pipeline, and regular reporting.

Process

How the work unfolds.

  1. Phase 1

    Triage

    Identify affected systems, assess exploitability and agree priorities with your security and risk teams, fast.

  2. Phase 2

    Contain

    Apply virtual patches, firewall rules and emergency fixes to reduce the immediate risk while root causes are addressed.

  3. Phase 3

    Remediate

    Upgrade PHP, update dependencies, fix vulnerable code and harden servers, with every change tested before release.

  4. Phase 4

    Assure

    Re-test, document the evidence for auditors and regulators, and set up continuous monitoring so you stay protected.

FAQ

Common questions

How quickly can you respond to a critical PHP vulnerability?

For urgent issues we prioritise triage and containment from the moment we are engaged, typically using firewall rules and virtual patching to reduce risk within the first day while permanent fixes are prepared. Clients on a support retainer receive priority response under their SLA.

Can you fix PHP code that we did not write, or that has no documentation?

Yes. Much of our remediation work is on legacy or inherited code. AI-assisted code analysis helps us map unfamiliar codebases quickly, and we document what we find so your team is not in the same position again.

Will upgrading PHP break our systems?

Not if it is done carefully. We build automated regression tests around critical functionality before we change anything, use automated refactoring tools to handle breaking changes, and roll out in stages with tested rollback plans.

Is this only for banks?

No. Financial institutions face the strictest obligations, but any organisation running PHP applications, including insurers, government, healthcare, education and e-commerce, benefits from the same approach.

Can you work with our existing security team or provider?

Yes. We regularly work alongside internal security teams, managed security providers and penetration testers, under your change-management, confidentiality and access requirements.
