Application security & technical assurance

Find the weakness. Fix the system that permitted it.

I combine architecture review, source-assisted analysis, and authorized adversarial testing to identify exploitable weaknesses, systemic control gaps, and the engineering changes needed to address them.

Security Assessment & Hardening

Scoped engagement · assessment → validation → remediation roadmap

Establish where your security posture actually stands, not just what a scanner reports. Engagements are scoped to the system and the decision in front of you, with clear authorization, rules of engagement, and evidence-backed findings.

  • 01Web application & API penetration testing
  • 02Authentication, authorization & business-logic testing
  • 03Source-assisted security review
  • 04Architecture & attack-surface review
  • 05Cloud, configuration & dependency exposure
  • 06Secrets & credential handling
  • 07Logging, monitoring & detection posture
  • 08Sensitive-data flows & third-party boundaries
  • 09Vulnerability disclosure & incident escalation
  • 10Prioritized remediation roadmap
  • 11Remediation validation & retesting
Methodology
existing systems

A finding is useful only when the response reduces real risk.

  1. 01

    Assess

    Map the system, trust boundaries, assets, attack surface, and controls that matter.

  2. 02

    Validate

    Use source-assisted analysis and authorized adversarial testing to separate exploitable risk from scanner noise.

  3. 03

    Remediate

    Trace findings to root causes and give engineering a prioritized, practical path to resolution.

  4. 04

    Harden

    Improve architecture, defaults, tests, and operational controls so the same class of failure is less likely to return.

  5. 05

    Monitor

    Confirm that logs, alerts, and ownership make meaningful security events visible and actionable.

  6. 06

    Respond

    Establish clear disclosure, escalation, and incident-response paths before they are needed.

How engagements
work

Clear scope. Useful evidence. Engineering-ready outcomes.

Every assessment starts with written authorization and rules of engagement. Testing stays aligned to the systems, risks, and business decisions that matter.

Typical deliverables
  • Executive risk summary and attack-surface narrative
  • Evidence-backed findings with reproduction guidance
  • Prioritized remediation roadmap for engineering
  • Retest results and remediation validation
  1. 01

    Scope & authorize

    Define assets, test windows, contacts, exclusions, data-handling expectations, and escalation paths.

  2. 02

    Assess & communicate

    Test the agreed surface, validate exploitability, and escalate critical findings without waiting for the final report.

  3. 03

    Remediate & retest

    Work through root causes and practical fixes, then verify that remediation closes the issue without creating adjacent risk.
