What we test

Every engagement ends the same way: severity-ranked findings, reproduction steps, and remediation guidance written for the people who will do the fixing.

Your engagement

From scoping call to final retest

You always know what phase we are in, and you hear about critical findings the day we confirm them.

01

Scoping call

We agree on targets, test accounts, timing, and rules of engagement. Usually 30 minutes.

02

Testing

Manual testing over one to three weeks depending on scope. You get a heads-up the moment anything critical turns up, not at the end.

03

Report

Severity-ranked findings with reproduction steps, CVSS scores, and fixes written for the engineers who will apply them.

04

Debrief & retest

A free 60-minute walkthrough of the report. Critical and high findings are retested after you fix them, at no extra charge.

In their words

What our students say

“I really enjoyed learning with you. You explain things in a very simple manner and give exercises so I can also learn with hands-on experience. If I have any doubts, you always take the time to explain them in a better way. I've also started understanding the tools and concepts much better, and even if I miss a class, I get to watch the recorded session. Thank you!”

Harika

Mentorship Student, India

“I really appreciate the way the sessions were organized, the explanations were clear, and the pace of the lessons was just right, making it easier to grasp even the more complex topics. The learning process is much easier and engaging. Overall, it's been a great learning experience, and I really appreciate the effort put into making the lessons both interactive and easy to follow.”

Ishank Nain

Mentorship Student, Studying in the UK

“Everything is going really well and I'm really enjoying it. I really like the way you explain things, you're clear, calm, patient, and you make the subject interesting and easy to follow. It's obvious that you prepare well and care about our pace, which makes a big difference. Thanks for making me feel so comfortable!”

FAQ

Frequently asked questions

How do I know if my application needs a penetration test?

If your application handles user data, payments, authentication, or any sensitive information, it needs a penetration test. Regulatory frameworks (PCI-DSS, ISO 27001, SOC 2) often mandate them. Even if compliance doesn't require it, the cost of a penetration test is a fraction of the average cost of a data breach. We recommend testing before major releases, after significant architectural changes, and at least annually for production applications.

What makes manual penetration testing better than automated scanning tools?

Automated scanners identify known, pattern-matched vulnerabilities, they cannot understand business logic, chain attack paths, or reason about how your specific application could be abused. HackproofHacks engagements are conducted by a senior analyst who uses automation as a starting point, then applies human reasoning to discover the vulnerabilities that matter most. The result reflects how a real attacker would approach your application, not a list of raw scanner output.

Do you test mobile applications?

Mobile app security testing is available as part of our API security engagements, since most mobile vulnerabilities reside in the backend API the app communicates with. Static analysis of the mobile binary (Android APK or iOS IPA) and dynamic testing via traffic interception are available as add-ons. Contact us to discuss your specific requirements.

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment identifies and classifies known vulnerabilities through scanning and manual review, it stops at discovery. A penetration test goes further: findings are actively exploited to demonstrate real-world impact, chained attack paths are explored, and business-logic flaws are uncovered through attacker-like creative thinking. For regulated industries or critical applications, a full penetration test provides stronger evidence of security posture.
