Scoping
Scope, environments, roles, subscription plans, and restrictions.
OSCP Expert — Multi-Tenant Platforms
One client seeing another's data
On a SaaS platform, the critical vulnerability isn't technical: it's a breakdown in isolation. We'll find it using two client accounts.
- Isolation between organizations: data, files, exports, search
- Roles and invitations — elevation from an invited or revoked account
- Subscriptions and quotas: bypassing paid plan limits
- Integrations, webhooks, and API keys issued by your clients

Why now
Your clients will ask for it before renewing
A SaaS provider eventually receives a security questionnaire. A penetration test report answers it as an attachment, and shortens the sales cycle.
- Large accounts evaluate their providers: it's mandatory for those under NIS 2, and an established practice for others.
- The question of isolation always comes up — because it's the only one that can cost you all your clients at once.
- A test before a funding round or certification avoids discovering the issue during the acquisition audit.
- Retesting after correction provides proof that the gap has been closed, dated.
All missions require a written mandate and an authorized scope.

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.

About your contact
I am a cybersecurity consultant: I support IT teams and management on audit, penetration testing, and hardening topics. My background is field-oriented (SMEs, mid-sized companies, e-commerce, industry) with a simple requirement: actionable findings, not jargon.
Why this profession: making real risks visible to help make quick decisions — securing also means clarifying what matters for the business.

Pedagogy: translating technical details into business decisions (prioritization, budget, planning).
Frequently asked questions
What you'll be told before you ask
Can we test without impacting our clients?
Yes. Tests are conducted on test organizations you create, and destructive actions are excluded by agreement. Sensitive times are avoided during scoping.
Is the report shareable with our clients?
The deliverable includes a summary designed for sharing — scope, methodology, residual risk level — without exposing the technical details of corrected vulnerabilities.
Do you also test the infrastructure?
On request, if the hosting is within your scope of responsibility. For a platform hosted by a cloud provider, the shared responsibility model is defined beforehand.
How often should we retest?
Once a year, and after any significant changes: new role model, billing overhaul, opening of a public API.
