Security Assessments & Pentesting

Knowing how vulnerable your systems are is a different matter than hoping everything will be fine. Our security assessments and pentesting/penetration tests go beyond tools and checklists: manual investigation, realistic attack scenarios and concrete remediation advice that your team can directly act on. From web application pentests based on OWASP Top 10 to AI red teaming — we test what others skip. Web pentest and security assessment

Security that's more than a checklist

Security audits and penetration tests are sometimes viewed as a mandatory checkbox: a supplier delivers a report with a coloured dashboard, findings are ticked off, and the report disappears into a folder. We do not believe in that approach. A pentest has value only when findings are concrete, are in the context of your organisation, and lead to structural improvements in development, configuration and monitoring. Our security specialists combine automated scans with manual exploitation techniques to find vulnerabilities that tools miss: business logic flaws, chained vulnerabilities and edge cases in authorisation.

For every project, we define a scope in advance that aligns with your risks. For a SaaS platform, that means an authenticated web application pentest including APIs, role-based access control and tenant isolation. For a cloud environment, we map IAM configuration, network segmentation, data-at-rest and logging. For an internal network, we look at Active Directory, lateral movement and privilege escalation opportunities. We work according to OWASP, PTES and NIST methodologies and deliver findings according to a standardised CVSS scoring model.

A pentest with us does not end with the report. We organise a debrief with your development team and ops team, discussing findings technically rather than only at management level, and offer remediation guidance. For critical findings, we plan a retest so you can demonstrably show that the vulnerability has been fixed — important for both clients and auditors. If you want continuity, we set up a pentest-as-a-service model with recurring quarterly tests on changing scopes, so security is a continuous process rather than an annual peak.

Frequently asked questions about security testing

What is the difference between a pentest and a vulnerability scan?
A vulnerability scan is automated: a tool checks known CVEs against your systems and produces a list. A pentest is manual and targeted: an experienced tester actively tries to exploit vulnerabilities, chains weaknesses to gain higher privileges, and tests business logic that tools cannot understand. Both have their place — scans for continuous monitoring, pentests for depth.
Do you also conduct red team assessments?
Yes. A red team engagement goes further than a pentest: we simulate a realistic attacker with social engineering, phishing, physical access where relevant and lateral movement through your network. The goal is not only to find vulnerabilities, but also to test how your detection and response chain performs against a motivated adversary. These engagements require a mature security baseline — we recommend a regular pentest first if you don't yet have assurance over the basics.
How do you handle sensitive findings?
All findings are treated as strictly confidential. Reports are exchanged end-to-end encrypted, stored on European infrastructure and not reused in other projects. With serious vulnerabilities that risk active exploitation, we inform you directly rather than waiting for the final report. A signed NDA is standard, and for organisations with special requirements (for example government or healthcare), we can make additional clearance agreements.
