Application Security Penetration Test

Across web, API, and mobile applications, we validate critical business workflows through controlled testing.

We test web, API, and mobile applications from an offensive security perspective. We verify authentication, authorization, and business-logic findings, then prioritize the results by business impact. We deliver an executive summary, a technical report, and a remediation plan together.

    • Critical user workflows are verified through manual testing and safe PoC.
    • Authentication, authorization, tenant boundaries, and business logic are assessed together.
    • Remediation priority brings technical severity and business impact into a single order.

// WHAT IT IS / ISN'T01

What this service is, and is not

It is
  • It tests the critical workflows in web, API, and mobile applications from an attacker's perspective, under controlled conditions.
  • It documents verified technical findings with safe PoC and reproduction steps.
  • It enables management and technical teams to build a remediation plan from the same risk picture.
It is not
  • Not a rhythm-based continuous-validation program like Continuous Penetration Testing.
  • Not the attack-path and detection-gap scenario of a Modular Red Team simulation.
  • Not an automated-scanner output alone; it includes manual validation and a safe PoC.
// SCOPE MATRIX02

Scope and boundaries

  • Web, API and mobile application surface components
  • Authentication, authorization and tenant separation
  • Business logic and critical-flow breaks
  • Proven exploit validation and safe PoC production
  • Fix-first prioritization (CVSS + EPSS + business impact)
  • Fix validation / retest when needed
Controlled testing

Testing is carried out with written authorization, an approved scope, stop conditions, and an escalation channel.

// SERVICE METHODOLOGY03

How we work: five steps from scoping to retest

  1. Scope & critical-flow clarification

    It is clarified which components (Web, API, Mobile) are tested and to what extent, which critical flows take priority, and the rules of engagement are approved.

  2. Manual discovery & surface mapping

    The target surface is examined with an attacker's eye; role-based flows, authority boundaries and business logic are mapped.

  3. Flow-based testing & exploit validation

    We run manual tests on critical user workflows and verify exploitable findings with a safe PoC that preserves production integrity.

  4. Fix-first backlog production

    We assess the findings we have verified together with business impact, CVSS, and EPSS data, and prepare an executive summary, a technical report, and a remediation plan.

  5. Post-remediation retest

    After the client remediates selected findings, we run a retest and report that the finding has been technically resolved.

// OUTPUT EXAMPLES04

What we deliver

Management

Executive summary

  • Risk picture: summarizes the critical findings, business impact, and remediation order.
  • Retest result: shows the status of the finding after the client's remediation.
Technical

Technical report and remediation plan

  • Technical report: covers the finding's impact, reproduction steps, and the recommended control.
  • Safe PoC: shows the steps required to reproduce the critical finding in a controlled environment.
  • Remediation plan: ranks the findings by business impact and exploitability.
Optional

Optional outputs

  • Re-test note: revalidation summary of selected findings (add-on).
  • API scope/inventory summary and authentication schema; a MASVS coverage matrix for mobile.
Which decision do these outputs accelerate?

Management sees which risk to address first. The technical team follows how the finding was reproduced and which control will remediate it.

Which is the right start, and when?

These three services do not solve the same problem. Starting without knowing the difference wastes time and budget chasing the wrong evidence object.

// EVIDENCE IN PRACTICE07

One example of decision clarity

Anon case · PT-1 · multi-tenant SaaS

New sharing layer: is the tenant boundary protected by evidence?

Starting uncertainty

A SaaS provider gave us a scope to test its web and API workflows before releasing a new authorization model. We agreed on written authorization, test accounts, and stop conditions.

Proven reality
Technical reality · scene evidenceEXH-PT1-0207validated by the offensive team OWASP ATPM 1.2
Verified

Our manual testing surfaced two critical tenant-isolation findings. We verified each finding with a safe PoC and reproduction steps.

Decision impact

We delivered the executive summary, the technical report, and a remediation plan ranked by business impact. After the client remediated the findings, our retest confirmed that both findings had been resolved.

Decision value

What this case produced

  • The release decision was based on verified application findings.
  • Critical findings were remediated before release.
  • The remediation status was confirmed by retest.

// FAQ09

Frequently asked questions

Application Security Penetration Testing performs deep testing on a specific release or scope. Continuous Penetration Testing, by contrast, tests the same surface regularly in line with your release cadence and tracks remediation status periodically.

A retest is scheduled once the client has remediated the finding. The same steps are applied again, and the finding's resolution is verified technically.

Web, API, and mobile surfaces can be assessed both externally and internally with role-based test accounts. The test environment and access model are determined during the scoping discussion.

The standard scope covers testing against the running application. If a full source code review is needed, a separate scope and proposal are prepared.

A safe PoC is prepared for critical and high-severity findings. The PoC shows the reproduction steps in a way that preserves production integrity.

Remediation priority is determined by assessing CVSS, EPSS, exploitability, and business impact together. The result is turned into a plan with a clear owner and order.
