Our expertise in action: high‑value cybersecurity engagements
Project references
Each engagement addresses specific regulatory, technical, or organizational challenges.
Our teams work in sensitive environments, conduct advanced penetration tests, perform application security audits, and support compliance with market standards.
Below are two examples illustrating our cybersecurity expertise: penetration testing in the context of DORA, web application security audits, and support for SOC 2 requirements — delivered through a rigorous methodology aligned with real threats and each organization’s needs.
DORA compliance penetration testing
For a European company in the financial sector, we carried out a comprehensive penetration testing campaign as part of DORA compliance. The objective was to assess the resilience of the information system against realistic attack scenarios. Our teams conducted a grey‑box internal penetration test, a black‑box external penetration test, and a targeted phishing campaign. Results were consolidated into both technical and executive deliverables, enabling prioritized remediation in coordination with the managed service provider. The project was completed within one month by two senior technical experts.
Web security audit for a technology platform
We supported a technology company developing a financial data management and analytics application by conducting a web security audit aligned with SOC 2 requirements. Testing was performed in black‑box conditions across AWS and GCP environments, complemented by an AWS configuration review. Technical deliverables included recommendations, an action plan, and support during clarification phases. This fully remote engagement mobilized two experts over two weeks to strengthen application security and meet client expectations.

Your questions about cybersecurity — ADVANS Group answers
Frequently Asked Questions (FAQ)
Are you wondering about regulatory requirements, security testing, or cybersecurity compliance approaches?
This FAQ brings together answers to the most common questions to help you better understand our expertise, our methodologies, and the support solutions offered by CORALIUM, an ADVANS Group company, from penetration testing to governance and compliance (ISO 27001, SOC 2, NIS2, DORA, etc.).
Security audit vs penetration test
What’s the difference between a security audit and a penetration test?
A security audit assesses the overall maturity level of your security posture based on a reference framework (ISO 27001, NIST, SOC 2, etc.).
A penetration test simulates a realistic attack to identify exploitable vulnerabilities. The two approaches are complementary: the audit structures security, while the pentest measures real-world exposure.
Penetration testing
When is penetration testing mandatory?
Penetration tests are often required in the context of:
- DORA for financial entities (threat-based testing),
- SOC 2 or ISO 27001 for SaaS vendors,
- Tenders or customer requests requiring proof of application robustness.
Black box, grey box, or white box
Black box, grey box, or white box: which should you choose?
- Black box: no information provided, ideal for simulating an external attacker.
- Grey box: user-level access provided, the most realistic internal scenario.
- White box: access to code or configurations, useful for complex environments.
CORALIUM recommends the appropriate approach based on your exposure, constraints, and maturity.
NIS2, DORA or SOC 2
How do I know whether I need to prepare for NIS2, DORA, or SOC 2?
- DORA: if you are a European financial entity (or a critical ICT provider).
- NIS2: if you operate in essential or important sectors (industry, healthcare, energy, etc.).
- SOC 2: if you sell B2B, SaaS, or cloud services to large enterprise customers.
We help you quickly assess your scope and obligations.
Typical engagement duration
How long does a typical engagement last?
Depending on the type of engagement:
- Application penetration testing: 3 to 7 person-days,
- Internal / external testing: 3 to 7 person-days,
- ISO 27001 / NIST audit: 2 to 3 weeks,
- Compliance support: several months depending on requirements.
CORALIUM always provides a schedule tailored to your organization.
Pentest deliverables
How are penetration test results presented?
Deliverables typically include:
- An executive summary,
- A technical summary,
- Threat scenarios,
- A vulnerability table (CVSS scoring),
- A prioritized action plan.
The goal is to make results immediately actionable for both technical teams and management.
Phishing
Is phishing included in a penetration test?
It can be included as part of a broader engagement (DORA, internal testing) or delivered as a standalone service.
CORALIUM, an ADVANS Group company, offers simple, advanced, or spear-phishing campaigns, as well as awareness and training programs.
Organizations we support
What types of organizations do you work with?
We work with all types of organizations:
- SaaS / B2B software vendors,
- Mid-sized companies and connected industries,
- Fintech and financial services,
- Local authorities, healthcare, public services,
- IoT / embedded manufacturers subject to CRA / RED.
