Threat model
Permissions and roles grew without a shared model. Assets, actors, inputs, boundaries and abuse scenarios. The decision is documented with owners, boundaries and a concrete way to verify it.
Applicable risk
PHP application security integrated into product evolution
We review controls against actual assets, actors and flows. We prioritize exploitable risk and sustainable changes without presenting a checklist as a guarantee of absolute security.

Security the team can maintain
The goal is to reduce exposure and improve detection, response and learning—not accumulate controls disconnected from the system.
- Permissions and roles grew without a shared model.
- Sessions or secrets depend on historical configuration.
- Uploads, imports or user HTML lack a consistent policy.
- Dependencies are not inventoried or prioritized by exposure.
- Sensitive changes lack sufficient audit history.
From a symptom to a capability the team can operate
We do not treat each need as an isolated feature. We connect the problem to data, rules, dependencies, people and operations so the solution remains understandable after delivery.
Control review
Sessions or secrets depend on historical configuration. Authentication, authorization, session, CSRF, XSS, SQL and files. The decision is documented with owners, boundaries and a concrete way to verify it.
Dependencies and secrets
Uploads, imports or user HTML lack a consistent policy. Inventory, exposure, rotation and environment configuration. The decision is documented with owners, boundaries and a concrete way to verify it.
Finding register
Dependencies are not inventoried or prioritized by exposure. Evidence, contextual severity, impact and recommendation. The decision is documented with owners, boundaries and a concrete way to verify it.
Remediation
Sensitive changes lack sufficient audit history. Reviewable changes with tests and controlled delivery. The decision is documented with owners, boundaries and a concrete way to verify it.

How we know the work is creating value
For PHP security we do not measure progress by code volume. We look for verifiable change in behaviour, risk, team autonomy and operating capability.
We first agree which situation must change and what evidence will demonstrate the outcome. It may be a flow no longer dependent on manual steps, a rehearsed recovery, a centralized rule or a signal enabling earlier diagnosis. Without that reference, a technically correct delivery may still miss the problem.
We then verify that the capability can be maintained: code is reviewable, data retains integrity, failures have a known response and important decisions do not depend on oral memory. Closure includes remaining boundaries and next priorities rather than a promise of perfection.
- Verified behaviour and acceptance criteria.
- Documented risks, assumptions and exclusions.
- Prepared release, observation and recovery.
- Accessible knowledge for continued evolution.
What must be decided with context
We make conditions and limits explicit to avoid universal recommendations.
An application review does not replace independent penetration testing where required.
Classification depends on context and existing controls.
Remediation must protect compatibility and operations.
Questions before starting
Answers about scope, evidence and ways of working.
Do you perform penetration testing?
We review and harden applications; independent offensive testing is agreed as specialist scope.
Does an audit guarantee no incidents?
No. Security reduces risk and improves detection and response; absolute guarantees do not exist.
Do you fix the findings?
Yes when implementation is included, using small changes, tests and verification.
Do you review dependencies?
Yes, relating known vulnerabilities to actual use, exposure and upgrade feasibility.
