Frequently Asked Questions

❓ What’s the difference between this and a vulnerability scan?

Most vulnerability scans are automated tools that generate false positives and generic results. I conduct a manual-first assessment, simulating real-world attack techniques tailored to your tech stack and app logic.

❓ What access do you need?

Typically, just a staging or test environment and credentials for a standard user role. I don’t need production access unless absolutely required — and I never run intrusive tests on live sites without permission.

❓ Will this affect my application’s availability?

No. My methodology is designed to be non-disruptive. I avoid denial-of-service or brute-force attacks unless explicitly scoped in. Your team can continue using the platform during testing.

❓ What does the final report include?

You’ll receive a professionally formatted PDF report with: • Clear findings (title + description) • Severity ratings • Steps to reproduce (with screenshots) • Fix recommendations • OWASP/CWE mappings • Optional: executive summary and retest validation

❓ How do you price this service?

Pricing is based on project complexity and time required. Add-on services like expedited delivery, retesting, or extra consulting are available at a flat rate.

❓ Can I talk to you before purchasing?

Of course. Message me any time if you’d like to discuss scope, requirements, or timelines. I’m happy to jump on a quick call or clarify things over chat.

We recently engaged Marco through Vulnn to carry out a web application penetration test for one of our production environments and we were genuinely impressed. From the moment we landed on his service page, it was clear that this wasn’t going to be a generic scan. The way he laid out the scope, testing methodology, and deliverables gave us immediate confidence. It was clear, technical, and thoughtfully structured.

Communication was seamless throughout. Marco was responsive, asked the right questions about the tech stack and business logic, and made sure he understood our priorities before beginning. The actual testing process was thorough and methodical. He uncovered several issues we weren’t aware of, including logic flaws and session handling weaknesses that automated scanners had completely missed in previous reviews.

The report was one of the best we’ve seen. It was clearly written, with detailed steps to reproduce, proper CVSS scoring, and practical remediation advice. It was genuinely developer-friendly, which is not always the case. We also appreciated the optional add-ons. We opted for the video walkthrough and the executive summary, which made internal stakeholder communication much easier.

Overall, this was an incredibly high-value engagement. For any team looking for serious manual testing with real-world context, Marco’s service on Vulnn is an excellent choice.
