HackproofHacks does manual penetration testing of web applications and APIs. Every engagement is tested by hand, and you leave with a report your engineers can actually fix things from, plus a call to walk through it together.
Run one of the same first-day checks we do in a paid engagement. Results run in your browser and are never stored.
Every engagement ends the same way: severity-ranked findings, reproduction steps, and remediation guidance written for the people who will do the fixing.
Manual testing against the OWASP Top 10 and beyond: authentication, authorisation, business logic, and the chained attack paths scanners can't follow.
REST, GraphQL and gRPC endpoints tested against the OWASP API Top 10: BOLA, broken auth, excessive data exposure, and logic flaws specific to your endpoints.
Recurring scans, monthly risk reports, and prioritised remediation guidance so you know your exposure over time, not just once.
The process is deliberately simple. You always know what phase we're in, and you hear about critical findings the day we confirm them.
We agree on targets, test accounts, timing, and rules of engagement. Usually 30 minutes.
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.
Severity-ranked findings with reproduction steps, CVSS scores, and fixes written for the engineers who will apply them.
A free 60-minute walkthrough of the report. Critical and high findings are retested after you fix them, at no extra charge.
Built for our own recon work, free for anyone to use. No signup, and your results are never stored.
Live teaching, real labs, and a curriculum built from ten years of actual engagements. Over 10,000 learners so far.
4-to-8-hour deep-dives on one technique or tool, with beginner and advanced tracks. Case studies come from real engagements.
Live group sessions three times a week, max 20 students per cohort. 12 modules, 120+ hours, certificate on completion.
Private sessions with Hassan: custom roadmap, portfolio review, interview prep, and direct async support between sessions.
“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!”
“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.”

“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!”

The networking foundations every hacker actually needs, IP addresses, ports, protocols and the handshake, explained the way they matter on a real engagement.
A grounded roadmap into cybersecurity, from the foundations you actually need to the roles you can aim for and the first job that gets you in the door.
A hacker's guide to locking down your home network, six practical steps that close the doors attackers actually use, explained in plain language anyone can follow.
Hassan Ansari has spent over ten years finding vulnerabilities in production web applications, APIs, and infrastructure. He runs every HackproofHacks engagement personally, teaches the training programmes live, and writes up what he learns for a community of more than 212,000 followers.
“Security isn't a product you buy. It's a process you build — one vulnerability, one fix, one lesson at a time.”Read Hassan's story
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.
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.
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.
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.
