About this Gig
Most startups discover vulnerabilities only after a breach leaked data, compromised accounts, reputation damage. I run manual penetration tests on web applications and APIs the same way a real attacker would, but before they get the chance.
What I test:
- SQL, NoSQL, and command injection
- Broken authentication and session management
- XSS, CSRF, and access control flaws
- API security and business logic vulnerabilities
- Full OWASP Top 10 coverage
What you get:
- Detailed PDF report with every vulnerability found
- Severity ratings with CVSS scores
- Clear fix recommendations your dev team can act on immediately
- Executive summary for non-technical stakeholders
I'm a Senior Information Security Specialist with 5+ years in enterprise security SOC operations, WAF administration, and real-world incident response. I mitigated a 220,000 RPS DDoS attack with zero downtime. This is not an automated scan. Every finding is manually verified and actually matters to your application.
Message me before ordering and I will recommend the exact package you need.

FAQ
Do you use automated scanners or manual testing?
Both — but every finding is manually verified. You will not receive a raw scanner dump.
Black-box, white-box, or grey-box?
Your choice. Grey-box is most common and cost-effective — I recommend it for most clients.
Will this affect my live application?
Testing is conducted carefully to avoid disruption. A staging environment is recommended but I have extensive experience testing production systems safely.
What if you find critical vulnerabilities?
I notify you immediately via message before the final report so you can start remediation right away.
Is a retest included?
Yes — included in the Premium package. For Basic and Standard it can be added as an extra.
