Comprehensive security testing approach
Scoping
Before testing begins, we establish a clear scope together. Open communication sets a comfortable foundation and keeps the assessment focused on what matters to your business.
Information Gathering
OSINT and reconnaissance help map your attack surface - domains, infrastructure, and dependencies - so risk is assessed accurately throughout the engagement.
Security Testing
Manual and automated testing across agreed targets. Controlled exploitation validates real impact while protecting production stability and sensitive data.
Reporting
Findings are consolidated into an executive summary and a detailed technical report with severity ratings, reproduction steps, and remediation guidance.
Final Discussion
We walk through fixes, verify closures with retests where needed, and deliver a remediation report showing the improved security posture of your application.
Hall of Fame
Recognized by Siemens CERT and other security programs for responsible disclosure.
Frequently Asked Questions
Common questions before booking an assessment
How long does a security assessment take?
Most web and API assessments run 5-10 business days once scope is agreed. Mobile and cloud reviews vary with app complexity and environment size. I share a timeline during scoping so you know what to expect before we start.
What deliverables do I get?
Every engagement includes an executive summary, detailed findings with severity ratings, proof-of-concept steps, and remediation guidance. Critical and high issues get extra attention so your team knows exactly what to fix first.
Do you sign NDAs?
Yes. I work under NDA for most client engagements. Credentials, staging URLs, and reports stay confidential. Happy to use your standard NDA or provide one.
Do you offer retesting after fixes?
Yes. One retest round is included for validated findings once you have patched. You receive an updated report showing what is closed and what still needs work.
What is the difference between a vulnerability scan and penetration testing?
Automated scans surface known issues quickly but miss business logic, chained exploits, and context-specific flaws. Penetration testing combines manual testing, custom tooling, and real attack scenarios to find what scanners miss.
Do you work with startups or only large companies?
Both. I have tested 300+ applications across startups, scale-ups, and enterprise teams. Scope and pricing flex to match your stage - from a focused pre-launch review to a full product assessment.
