Frequently asked questions

Penetration testing in Belgium typically costs between €5,000 and €50,000, depending heavily on scope, target type (e.g., web app, network), complexity, and the provider’s expertise.

Pick companies with strong credentials (certifications like OSCP, CREST), relevant experience in your sector, transparent testing methodology, good transparency in reporting, and a proven track record with Belgian / EU-GDPR / NIS-law compliance.

It helps uncover vulnerabilities before attackers do. Also ensures you meet legal obligations (like GDPR / NIS2 / Data Protection Authority expectations), protect customer trust, and avoid financial and reputational damage.

At minimum, once a year. But more frequent tests are advised if your systems change, new infrastructure is added, or you handle sensitive data. In high-risk sectors, quarterly or semi-annual testing may be more suitable.

Not explicitly mandated by a specific Belgian law, but GDPR Article 32 requires organisations to regularly test, assess, and evaluate the effectiveness of security measures. NIS2 and sector-based laws also impose obligations for risk management and technical security measures.

Pen tests provide evidence of technical controls in action, feed risk assessments, support GDPR obligations (Article 32), help meet NIS2 or ISO27001 requirements, and show due diligence. This helps reduce liability and satisfy regulator expectations.

Yes, remote penetration testing is common and effective for many assets (web apps, cloud, networks). The key is ensuring secure channels, a well-defined scope, proof of identity/authorization, and that physical or on-site components are covered as needed.
