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.

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.

FAQ
Frequently asked questions
Are you based in Paris?
We support many clients in the Île-de-France region with the possibility of on-site meetings in Paris. Technical missions are primarily conducted remotely.
What is the turnaround time for a quote?
After the initial discussion, a quote is usually provided within 24 to 48 business hours, depending on the complexity of the scope.
Do you work with SMEs?
Yes, we adapt our services to the budgets and constraints of SMEs and mid-cap companies — not just large corporations.
Is the initial consultation free of commitment?
Yes: the callback and scoping session are non-binding. A detailed quote will be provided before any billed mission; you decide whether to proceed solely if you wish.
What is the difference between an audit and a pentest?
An audit provides a snapshot of risks and exposure (configuration, attack surface, priorities). A pentest simulates a realistic attack to validate the exploitability of vulnerabilities. We will guide you to the right approach after the initial scoping.
Are my data and deliverables confidential?
Yes. Contact details, access credentials, and reports are treated as client deliverables and are not publicly disclosed. An NDA can be arranged for the mission upon request — in compliance with GDPR.
