Application & API Security

Prove the boundaries around data and actions.

Applications fail where identity, state, authority, data, and business rules meet. We test those boundaries as connected attack paths, not isolated checklist items.

ImpactWhat the business can lose.

How we test

Follow the behavior that creates real impact.

Coverage matters, but depth follows the architecture and evidence. Authentication, authorization, APIs, browser state, and business logic are tested as one system.

Attack-path validation

◎

Establish

Known-good workflows, roles, data relationships, and intended trust boundaries.

Challenge

Identity, sessions, object access, functions, inputs, APIs, and protected state changes.

⌁

Compare

Baseline and modified behavior separate exploitable conditions from noise.

□

Prove

Reproduce the material path and preserve evidence proportionate to the claim.

Where depth goes

The areas most likely to change the answer.

Testing effort follows the failure paths that can change business consequence, not equal time per checklist category.

Focused depth

◇

Identity & session

Authentication, MFA, recovery, federation, token use, logout, timeout, and replay.

▣

Authorization

Roles, object access, tenant boundaries, functions, hidden APIs, and server-side enforcement.

◎

Business logic

Sequence, approvals, quantities, limits, race conditions, and protected actions.

⌁

Input & browser

Injection, rendering, upload, API parsing, browser state, and client-side trust.

What you receive

Findings built for the people who must fix them.

The deliverable connects the claim to its reproduction path, affected behavior, consequence, remediation direction, and retest state.

Engineering-ready finding

Claim

The exact boundary and security condition.

□

Evidence

Requests, responses, browser state, or supporting artifacts.

⚒

Fix

Practical control change and root-cause context.

✓

Retest

Resolved, mitigated, open, or unable to verify.

Evidence that supports engineering action.

Best starting point

Bring the application, critical workflows, roles, and business action that matters.

We will turn that into an authorized test plan and evidence standard before testing begins.
