White-box penetration testing with source code review. Every finding includes working exploit proof and copy-paste fixes.
Websites · SaaS Platforms · E-commerce · APIs · Customer Portals
You built something that functions. Customers are using it. Revenue is coming in. But most web applications contain serious vulnerabilities their developers don't know exist.
Exposure of names, emails, passwords, payment information, or medical records. One vulnerability can compromise your entire user base.
Customer trust evaporates overnight. News spreads. Competitors capitalize. Recovery takes years - if it happens at all.
GDPR fines reach EUR 20M or 4% of global revenue. HIPAA violations start at $100/record. PCI-DSS non-compliance can terminate payment processing.
Your team pulled from roadmap work to patch critical flaws under pressure. Weekend deployments. Stress. Technical debt that compounds.
Automated scanners probe every IP on the internet. Your application gets tested by adversaries whether you hired a tester or not.
The question isn't whether someone will test your security.I review your source code, understand your architecture, and manually exploit vulnerabilities to prove they're real. No automated scanner PDFs full of false positives.
Analyze codebase for dangerous patterns: SQL queries, auth logic, session handling, input validation.
Test your running application with attacker eyes. Every finding includes working proof-of-concept code.
Demonstrate what an attacker could actually do: access data, escalate privileges, compromise systems.
Specific, code-level fixes in your technology stack. Copy-paste solutions, not generic advice.
Executive summary for leadership. Technical details for devs. Compliance mapping for auditors.
Building features, onboarding customers, iterating weekly. Security keeps getting deprioritized. I provide fast, focused assessment that doesn't slow your roadmap.
You process payments and store customer data. I test checkout flows, payment integrations, and customer account security for PCI-DSS compliance.
Users log in to access sensitive data - documents, financial info, healthcare records. I test authentication, session management, and access controls.
Your backend powers mobile apps and partner integrations. I test REST and GraphQL endpoints for auth bypass, injection flaws, and logic vulnerabilities.
No CISO or security team? I provide senior-level penetration testing accessible to growing companies - without enterprise overhead.
Offer security testing to your clients through white-label partnership. Add high-value services to proposals without hiring security staff.
Published flat rates. No surprise invoices. No proposal process.
Full white-box penetration test
Best for: Pre-launch validation, annual testing, first assessment
Book Assessment →Testing + remediation validation
Best for: Compliance requiring verified remediation, high-stakes environments
Book Assessment + Verification →Save $500 vs. quarterly one-time assessments
Best for: Active dev teams, ongoing compliance (SOC 2, ISO 27001)
Book Quarterly Program →Continuous security for fast-moving teams
Best for: High-velocity SaaS, Series A/B prep, sensitive data handling
Book Monthly Monitoring →"Two critical vulnerabilities would allow unauthenticated attackers to extract all customer data. Immediate remediation required."
"Authentication bypass allows forging admin tokens without credentials. Combined with SQL injection, enables complete system compromise."
"Public patient search contains SQL injection enabling extraction of all PHI including SSNs. Immediate HIPAA violation requiring emergency remediation."

Working exploit code demonstrating the flaw is real. No theoretical vulnerabilities.
Specific business consequences if exploited. Risk in financial and operational terms.
Secure code you can implement immediately. In your language, your framework.
Describe your application, tech stack, and concerns. I recommend the right service level. NDA signed if required.
Provide application URL, source code access (GitHub/GitLab or zip), and test credentials with different permission levels.
White-box penetration test: source code review + live exploitation. Findings validated and documented. No disruption to your operations.
Executive summary for leadership. Technical findings with proof-of-concept code. Remediation guidance with secure code examples.
Questions answered via email. Fix verification (Option 2+). Retesting after fixes deployed.
Total time from start to report: 48-72 hours
Offer security testing to your clients without building in-house expertise.
I founded Skyline Web Agency after seeing too many growing companies struggle with security testing that was either too shallow (automated scanners flooding teams with false positives), too slow (weeks to deliver reports), or too expensive (enterprise pricing inaccessible to growing businesses).
My approach: deep technical expertise, fast delivery, transparent pricing, and reports that actually help developers fix problems. I specialize exclusively in web applications.
Expert insights on web application security, penetration testing, and protecting your platform.
Three things: (1) Application access - URL of your staging or production environment, (2) Source code - GitHub/GitLab repository access or zip file, (3) Test credentials - 2-3 user accounts with different permission levels.
48-72 hours from when I receive access to all materials. Rush scheduling sometimes available for urgent situations.
Staging is preferred - you get security validation without risk to live data. I can test production with additional safeguards agreed in advance.
You receive a report documenting the testing scope and confirming your application's security posture. Valuable for compliance and customer assurance.
Yes. Standard mutual NDA before any source code access. Happy to use your template or mine.
Modern web stacks: JavaScript/TypeScript (Node.js, React, Vue, Angular), Python (Django, Flask, FastAPI), Ruby on Rails, PHP (Laravel, Symfony), Go, and associated databases.
Bug bounties find vulnerabilities in production after customers are at risk. I provide proactive assessment before launch, with guaranteed coverage and professional reporting for compliance.
Absolutely. Some teams prefer collaborative testing where I explain findings in real-time. Mention it in the consultation form.
If I fail to deliver the agreed report within the promised timeline, full refund. Professional services are rendered upon delivery.
Free 15-minute consultation. No commitment. Tell me about your application and I'll recommend the right approach.
