What Is Penetration Testing?
Penetration testing, also known as ethical hacking or security testing, is a controlled and authorised simulation of cyberattacks against an organisation's systems, networks, and applications. The objective is to discover exploitable vulnerabilities before malicious actors find and leverage them. Unlike automated vulnerability scanning, penetration testing involves skilled security professionals who think and act like real attackers, using the same techniques and tools that cybercriminals employ.
There are several types of penetration testing, each targeting different aspects of an organisation's security posture. Network penetration testing evaluates the security of internal and external network infrastructure, including firewalls, routers, servers, and network services. Web application penetration testing focuses on identifying vulnerabilities in websites, portals, and web-based applications, such as SQL injection, cross-site scripting (XSS), and authentication flaws. Social engineering testing assesses human-factor vulnerabilities through phishing simulations, pretexting, and physical access attempts.
Additional specialised testing includes cloud security assessments for on-premise and European cloud environments; wireless penetration testing for Wi-Fi networks and access points; and API security testing for application programming interfaces. ObsidianCorps offers all of these penetration testing services from our base in Luxembourg, tailored to the specific threat landscape and regulatory requirements of businesses operating in the Grand Duchy and the Greater Region.
Why Do Luxembourg Businesses Need Penetration Testing?
Luxembourg businesses face a unique combination of elevated cyber threat exposure and demanding regulatory requirements that make regular penetration testing not just advisable, but essential. As Europe's leading financial hub, Luxembourg processes over EUR 5 trillion in assets under management, making it an attractive target for organised cybercrime groups and state-sponsored threat actors.
The regulatory landscape in Luxembourg requires security testing across multiple frameworks. The Act of 5 May 2026 transposed NIS2 into Luxembourg law and entered into force on 10 May 2026. It requires essential and important entities to apply cybersecurity risk-management measures and assess their effectiveness. The CSSF (Commission de Surveillance du Secteur Financier) sets security-testing expectations for regulated financial institutions, while DORA requires relevant financial entities to maintain digital operational resilience testing programmes. GDPR, enforced by the CNPD, also requires organisations to evaluate the effectiveness of technical and organisational security measures.
A successful attack can interrupt operations, expose sensitive data and trigger regulatory or contractual obligations. Penetration testing provides a controlled way to validate security controls, demonstrate realistic attack paths and prioritise remediation before those weaknesses are abused.
What Does ObsidianCorps Penetration Testing Include?
ObsidianCorps follows a structured penetration testing methodology that combines industry-standard frameworks (OWASP, PTES, NIST SP 800-115) with our deep understanding of Luxembourg's regulatory environment. Every engagement is led by experienced security professionals and delivers actionable results.
Scoping & Planning
We define the test scope, objectives, rules of engagement, and communication protocols with your team. This phase ensures the test covers your highest-risk assets and aligns with any regulatory requirements such as NIS2 or CSSF obligations.
Reconnaissance & Discovery
Our testers gather information about your systems, services, and potential attack surfaces using both passive and active techniques. This mirrors the approach real attackers use when preparing to target an organisation.
Exploitation & Testing
We attempt to exploit discovered vulnerabilities to demonstrate real-world impact. This includes testing authentication mechanisms, access controls, encryption implementations, and business logic. All exploitation is controlled and documented.
Reporting & Remediation Support
You receive a comprehensive report with an executive summary, detailed technical findings, risk ratings, proof-of-concept evidence, and prioritised remediation recommendations. We include a debrief session and support your team during the remediation phase.
A typical penetration test for a Luxembourg SME takes 5 to 15 business days depending on scope. Network penetration tests for small environments can be completed in one week, while comprehensive assessments including web applications, cloud, and social engineering may require two to three weeks. Results are delivered within 5 business days of test completion.
How Much Does Penetration Testing Cost in Luxembourg?
Penetration testing costs in Luxembourg typically range from EUR 5,000 to EUR 25,000 per engagement, depending on several factors including scope, complexity, and the type of testing required. ObsidianCorps provides transparent pricing with detailed scoping to ensure you receive maximum value for your investment.
Key factors that influence penetration testing cost include the number and complexity of systems in scope, the type of testing (black-box, grey-box, or white-box), whether the test covers internal networks, external infrastructure, web applications, or all three, and any regulatory requirements that mandate specific testing approaches. A focused web application test for a single application typically costs EUR 5,000 to EUR 8,000, while a comprehensive assessment covering network, application, and social engineering components ranges from EUR 15,000 to EUR 25,000.
Luxembourg businesses can significantly reduce penetration testing costs through government subsidy programmes. The SME Packages programme, managed by Luxinnovation, can reimburse up to 70% of eligible digital transformation and cybersecurity projects for amounts between EUR 3,000 and EUR 25,000. ObsidianCorps is an approved provider for this programme and can assist with the application process. Additionally, the Fit 4 Cybersecurity programme offers free maturity assessments that can help identify priority areas for testing.

70% government subsidy available for cybersecurity projects: risk analysis, penetration testing, NIS2 compliance, and more.
"Penetration testing is not about checking a compliance box -- it is about understanding how an attacker would actually compromise your systems. In Luxembourg, where businesses handle some of Europe's most sensitive financial data, the stakes are too high for superficial security assessments. Every pentest we conduct is designed to simulate real-world attack scenarios specific to the Luxembourg threat landscape."
