Penetration Testing That Finds What Matters

Last reviewed: October 2026

Curios runs controlled, real-world attacks on your infrastructure, applications and cloud with senior OSCP-certified testers from Antwerp — prioritised, evidence-backed findings and practical remediation, so you fix what matters.

Deliverable: Report: executive summary, technical findings, proof of exploitability, risk ratings, prioritised remediation; optional retest.

Typical duration: A few days to a few weeks; start usually a couple of weeks after scoping.

Scope options: Web application & API · External / perimeter · Internal network (assume-breach) · Cloud (AWS, Azure, GCP) · Red team

Standards: OWASP WSTG · OWASP ASVS · PTES · NIST SP 800-115

Location: Belgian office; on-site across Belgium; remote throughout Europe.

External Infrastructure Testing

External Testing

Assess your internet-facing infrastructure to identify weaknesses attackers can reach before your team does.

Web Application Testing

Web Application Testing

Identify flaws in authentication, access control, input handling, and business logic across modern applications.

Internal Network Testing

Internal Network Testing

Simulate post-compromise attacker movement to expose privilege escalation paths, weak segmentation, and critical misconfigurations.

Cloud and Third-Party Exposure

Cloud & Exposure Validation

Assess cloud assets and externally exposed services to reduce risk across hybrid environments and third-party attack surfaces.

Our Approach

What We Deliver

Contact Us
Our Penetration Testing Services

From Belgium we simulate realistic attacks and show how attackers could reach your systems, applications, users and data.

  • Beyond automated scanning — exploitability validated, findings chained where appropriate.
  • Evidence-based reporting — business risk, technical accuracy, where defences hold and fail.
  • Actionable remediation — prioritised recommendations for technical and leadership teams.
  • Senior-led engagements — every test led by our senior specialists.
  • Continuous delivery — managed DevSecOps builds the same testing into your pipeline.

WHAT WE'RE OFFERING

Practical Penetration Testing

Manual expertise, an attacker mindset and technical validation across infrastructure, applications, cloud and internal environments.

Identify Real Attack Paths

Identify Real Attack Paths

Validates what is actually exploitable, not generic vulnerability lists.

Prioritize What Matters Most

Prioritize What Matters Most

Findings ranked by business risk, so fixes reduce exposure fastest.

Improve Security Maturity

Improve Security Maturity

Exploitation evidence and remediation guidance strengthen defences, detection and response.

Our Penetration Testing Approach

A Structured Path to Finding Exploitable Risk

Findings are verified, put in context and turned into next steps for technical and leadership teams — and the testing evidence auditors expect for NIS2 compliance.

Shape 01

Scoping

Objectives, in-scope assets, constraints, rules of engagement agreed up front.

Shape 02

Testing

Manual, targeted testing: vulnerabilities, misconfigurations, weak controls, attack paths.

Shape 03

Validation

Exploitability confirmed, impact assessed, weaknesses chained into realistic attacker outcomes.

Shape 04

Reporting

Decision-ready report: technical detail, business context, evidence, prioritised remediation.

SERVICE OPTIONS

Penetration testing — choose your target

One-off or recurring; every test is scoped and fixed-priced after a short call — scope a penetration test.

Web application & API

One app or API, before or after release.

External / perimeter

Internet-facing infrastructure.

Internal network

Assume-breach: lateral movement and privilege escalation.

Cloud

AWS, Azure or GCP configuration plus exploitation.

Red team

Full-scope, objective-based adversary simulation.

Every engagement can include retest — we verify agreed findings are properly remediated — and remediation support — hands-on help fixing issues, not just a report.

Local Expertise

Penetration testing in Belgium and across Europe

  • Belgian office — Curios works on-site across Belgium; remote throughout Europe.
  • Pentest or penetratietest — the same hands-on, exploit-driven engagement, whichever you call it.
  • OSCP-certified senior consultants — understand the Belgian regulatory context; findings written for engineers and the board.
  • Belgian sectors — manufacturing and automotive, financial services, insurance, healthcare, logistics, public sector.
  • On-site quickly — scoping workshops, internal network tests, debriefs; remote testing elsewhere.

Methodology

Recognised standards rather than an ad-hoc checklist: repeatable coverage, evidence defensible to auditors, nothing important skipped.

FAQ SECTION

Frequently asked questions

Fixed price, scoped up front after a short call — no open-ended day rates. Tell us the target (web apps, networks, cloud, number of assets) and you get a clear quote.

Senior specialists, not junior staff: OSCP, OSCE and CISSP, advanced Offensive Security training (OSWE web exploitation, OSED exploit development), 9+ years of hands-on testing, published CVEs. Sector references available under NDA.

Usually within a couple of weeks of scoping; most tests take a few days to a few weeks. Rules of engagement agreed up front keep live operations undisrupted; we work back from audit deadlines.

Neither names penetration testing as a hard requirement, but both require risk-based testing of security controls. In practice, auditors and Belgium's CCB expect evidence that you test for exploitable weaknesses, which a penetration test provides.

At least once a year, and after significant change — a new application, major infrastructure update, merger or move to the cloud. Organisations handling sensitive or regulated data often test more frequently.

WHO DOES THE WORK

Experts do the work

Board-level security leadership with hands-on technical depth: the consultants who advise your management also verify the controls.

  • 48+ certifications across the team — including CISSP, CISM, OSCP, OSCE and eWPT.
  • Published CVEs — including in widely-used enterprise products.
  • 9+ years of offensive pedigree — OSCP since 2017, OSCE.
  • References from your sector — available under NDA.
