Penetration Testing That Finds What Matters

Curios helps you uncover exploitable weaknesses, validate real-world attack paths, and prioritize remediation with clear, actionable reporting.

In brief: Penetration testing is a controlled, real-world attack on your infrastructure, applications, or cloud, run by senior testers to find exploitable weaknesses. You get clear, prioritised findings with practical remediation — so you fix what actually matters.

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

We work with your team — from our Antwerp (Antwerpen) office — to simulate realistic attacks against your environment and uncover the weaknesses that matter most. Our penetration testing goes beyond automated scanning by validating exploitability, chaining findings where appropriate, and demonstrating how attackers could impact your systems, applications, users, and data. For teams shipping software continuously, our managed DevSecOps service builds the same testing discipline into your build pipeline.

From scoping and reconnaissance through exploitation and reporting, we focus on clear business risk, technical accuracy, and practical remediation. You receive evidence-backed findings, prioritized recommendations, and a clear understanding of where your defenses hold up—and where they do not. Every engagement is led by our senior specialists.

  • Real-world attack simulation
  • Clear, evidence-based reporting
  • Actionable remediation guidance

WHAT WE'RE OFFERING

Practical Penetration Testing

Our penetration testing methodology combines manual expertise, attacker mindset, and technical validation to help your organization identify exploitable weaknesses and improve resilience across infrastructure, applications, cloud platforms, and internal environments:

Identify Real Attack Paths

Identify Real Attack Paths

Go beyond generic vulnerability lists with testing that validates what is actually exploitable in your environment.

Prioritize What Matters Most

Prioritize What Matters Most

Understand which weaknesses create material business risk so your team can focus on the fixes that reduce exposure fastest.

Improve Security Maturity

Improve Security Maturity

Use expert findings, exploitation evidence, and remediation guidance to strengthen defenses, detection, and response capabilities.

Our Penetration Testing Approach

A Structured Path to Finding Exploitable Risk

We follow a structured methodology to assess your attack surface, validate security weaknesses, and provide actionable remediation guidance. Our approach ensures findings are not just detected, but verified, contextualized, and translated into practical next steps for your technical and leadership teams, and into the testing evidence auditors expect for NIS2 compliance.

  • Define Scope and Attack Surface
  • Validate Exploitable Weaknesses
  • Deliver Clear Remediation Roadmap
Shape 01

Scoping

We define objectives, in-scope assets, test constraints, and rules of engagement to ensure the assessment aligns with your environment and risk priorities.

Shape 02

Testing

We perform manual and targeted testing across the agreed scope to identify vulnerabilities, misconfigurations, weak controls, and viable attack paths.

Shape 03

Validation

Our consultants validate exploitability, assess impact, and where appropriate chain weaknesses together to demonstrate realistic attacker outcomes.

Shape 04

Reporting

You receive a clear, decision-ready report with technical details, business context, evidence, and prioritized remediation steps.

SERVICE OPTIONS

Penetration testing — choose your target

Choose what you want tested — one-off or recurring. Every test is scoped and fixed-priced after a short call — scope a penetration test with our team.

Web application & API

A specific app or API, tested before or after release.

External / perimeter

Your internet-facing infrastructure.

Internal network

Assume-breach testing — lateral movement and privilege escalation.

Cloud

AWS, Azure or GCP configuration plus exploitation.

Red team

Full-scope, objective-based adversary simulation across the whole attack path.

Every engagement can include retest (we verify your agreed findings are properly remediated) and remediation support (hands-on help fixing the issues, not just a report handed over).

Local Expertise

Penetration testing in Antwerp and across Belgium

Curios runs penetration tests from our Antwerp (Antwerpen) office, working on-site with organisations across the city and the wider Flemish and Brussels regions, and remotely with clients throughout Belgium and Europe. Whether you call it a pentest or a penetratietest, the engagement is the same: hands-on, exploit-driven testing by senior, OSCP-certified consultants who understand the Belgian regulatory context. We test the systems that Belgian sectors depend on — manufacturing and automotive suppliers, financial services and insurers, healthcare providers, logistics operators and public-sector bodies — and report findings so your technical teams and your board can both act on them. Being based in Antwerp means we can be on-site quickly for scoping workshops, internal network tests and debriefs, while remote testing keeps engagements efficient wherever your infrastructure lives.

Methodology

Our testing follows recognised industry standards rather than an ad-hoc checklist. Web application testing is mapped to the OWASP Web Security Testing Guide and measured against the OWASP Application Security Verification Standard (ASVS); infrastructure and full-scope engagements follow the Penetration Testing Execution Standard (PTES) and NIST SP 800-115. Working from established methodologies keeps our coverage repeatable, our evidence defensible to auditors, and nothing important skipped.

FAQ SECTION

Frequently asked questions

We scope a fixed price up front after a short call — no open-ended day rates. Tell us your target environment (web apps, networks, cloud, number of assets) and we'll come back with a clear, fixed quote.

Scope your penetration test →

You work with senior specialists, not junior staff — our testers hold OSCP, OSCE and CISSP, are trained in advanced Offensive Security disciplines (OSWE web exploitation, OSED exploit development), and bring 9+ years of hands-on testing plus multiple published CVEs. Ask us for references relevant to your sector.

Scope your penetration test →

We can usually begin within a couple of weeks of scoping, and most tests run from a few days to a few weeks depending on scope. If you have an audit or board deadline, tell us and we'll work back from it — and we agree rules of engagement up front so your live operations aren't disrupted.

Scope your penetration test →

No — we combine manual, expert-led exploitation with targeted tooling to prove real attack paths and business impact, surfacing the exploitable issues automated scanners miss.

Scope your penetration test →

You get a clear report — executive summary, technical findings, proof of exploitability, risk ratings and prioritised remediation guidance — not just a data dump. After you remediate, we can retest to confirm the risk is genuinely closed.

Scope your penetration test →

Neither names penetration testing as a hard requirement. Both NIS2 and ISO 27001 do require risk-based testing of your security controls — and in practice auditors and Belgium's CCB expect evidence that you test for exploitable weaknesses, which a penetration test provides directly.

Scope your penetration test →

At least once a year, and again after any significant change — a new application, a major infrastructure update, a merger or a move to the cloud. Organisations handling sensitive or regulated data often test more frequently; we help you set a cadence that matches your risk.
