Offensive cybersecurity since 2018
Audit, penetration testing, and incident response. A report your developers can act on, not a list of theoretical vulnerabilities.
The problem
Months pass between intrusion and detection. During this time, the attacker is already inside your systems — and it's a client, a partner, or the CNIL who informs you.
Detection: 158 days on average
Reconstructed scenario. The delay is from the IBM report “Cost of a Data Breach 2025”: 158 days on average to identify a compromise.
An audit is this scenario played by us, under real conditions, before someone else plays it for real.
What our clients say
Reviews published on our Google listing by companies that have actually been audited. Verifiable, one by one.
We hired White-Hat to conduct a cybersecurity audit of all our servers, and we are very satisfied with the quality of their work. Philippe demonstrated professionalism, responsiveness, and excellent communication skills throughout the entire process. The recommendations provided were clear, relevant, and immediately actionable to strengthen our security. We highly recommend their services.
Excellent experience with White-Hat for a comprehensive security audit of our SaaS platform. The quality of service was truly outstanding: Philippe took the time to understand our application's architecture before starting the tests, which made all the difference to the relevance of the results. The report was detailed, with vulnerabilities categorized by criticality, concrete evidence of exploitability, and recommendations directly applicable by our technical team. The post-delivery follow-up to verify the patches was a real bonus. Professional, rigorous, and attentive: exactly what you need to secure a SaaS product.
We hired White-Hat for a comprehensive audit/advanced penetration test on our website, and it's clearly the direct contact with Philippe that makes all the difference. No salesperson between us, no unnecessary jargon: we communicate directly with someone who understands our challenges and can clearly explain the vulnerabilities found. The report was precise, with concrete evidence and recommendations that we were able to implement quickly. A truly trustworthy relationship; I highly recommend them.
Professional work. Thank you.
We urgently contacted White Hat following a suspected compromise of several servers. The team was extremely responsive and addressed our request within minutes, with clear communication at every stage. Their vulnerability analysis was conducted very rigorously, resulting in a detailed report and concrete, easy-to-implement recommendations to strengthen our security. The investigation of the compromised servers allowed them to quickly identify the source of the attack and contain the incident without any major disruption to our services. Professional, knowledgeable, and readily available, I highly recommend this provider for any cybersecurity intervention, especially in emergency situations.
Services
Comprehensive review of infrastructure and applications. Each flaw is reproduced, documented, and prioritized by real impact — not by theoretical CVSS score.
Black, grey, or white box. We go as far as exploitation and lateral movement, not just to an automated scanner report.
Compromise in progress: containment, post-mortem analysis, service restoration, and documented complaint filing. First response within 72 hours.
Realistic phishing campaigns and team training. The human element remains the primary entry vector in 8 out of 10 incidents.
Coverage
Our teams operate from Paris, Lyon, and Marseille. Remote tests start within 48 hours, on-site interventions within 5 business days.

Frequently asked questions
From 5 to 15 business days of testing depending on the scope. Between the scoping and the report delivery, allow an average of 11 days.
Yes, within a maintenance window validated in writing, with an on-call contact on your side. No destructive tests without explicit agreement.
A summary for management, detailed technical information reproducible for your developers, and prioritization by real impact — not by theoretical score.
No, it's included. Once your fixes are deployed, we re-run the tests on each reported vulnerability.
Nothing leaves the scope. Evidence is anonymized in the report, and collected data is destroyed after delivery.
Yes. First intervention within 72 hours in case of ongoing compromise: containment, analysis, then service restoration.
Yes, an audit agreement. It defines the exact scope, the intervention window, and the limits. Without it, no tests will begin.
First 30-minute consultation, no commitment, to define scope and budget.
