Penetration testing that shows where your company can actually be attacked

A penetration test is a controlled, authorized attack on your system, run the way a real attacker would but within an agreed scope and fully documented. The goal is not just to produce a list of vulnerabilities, but to prove what can actually be done with them: which data can be reached, which account taken over and how far into the infrastructure an attacker can go.

That is what separates a pentest from a vulnerability scan. A scanner compares what it sees against a database of known signatures and returns a list of alerts, often with many false positives. A pentester verifies every hypothesis by hand, chains individually harmless flaws into a single attack path and confirms it with a working proof. A scan can be part of a test, never a replacement for it.

The best moment to test is just before a system goes live for users, and after every significant change: a new feature, a cloud migration, an architecture change or an integration with an external provider. Each of those creates new attack surface that an earlier test did not cover.

Regardless of changes, we recommend at least an annual cycle, and a more frequent one in high-risk environments. A test is also often required outright by regulation or by a counterparty as part of due diligence. If an incident has occurred, a separate test after remediation confirms that the flaw was actually closed, not merely worked around.

Before we start, we agree the scope and rules of engagement together: which systems are in play, which techniques are allowed, the time windows we work in and who your point of contact is. That way you know exactly what happens and when, and the test does not disrupt production.

We match scope to real risk, not to a price list. A public web application is tested differently from an internal Active Directory network, and differently again from an OT environment where operational continuity is the priority. The choice of model, from black-box to white-box, directly affects the depth of coverage and the time the test needs.

We deliver the report in two layers. The technical part describes each vulnerability with evidence, a CVSS score and reproduction steps, so your team can confirm the issue and start fixing it immediately. The executive part explains the risk in business language, without jargon, so that priority decisions are made on real impact.

The most important work happens after the report is sent. We order fixes by actual risk rather than CVSS number alone, answer your team’s questions during remediation, and after the fixes ship we run a retest and confirm in writing that the flaw is closed. Without that step, the report remains just a document.

For a growing number of companies, penetration testing has stopped being good practice and become an obligation. DORA requires regular digital resilience testing from financial entities, NIS2 places risk-management and security-testing duties on essential and important entities, and the Polish NIS Act (KSC) covers operators of essential services and public bodies.

We prepare our reports so they can be put straight in front of an auditor and mapped to specific requirements, including the Annex A controls of ISO 27001. A test provides evidence that the declared controls actually work, which shortens and simplifies the later compliance audit.
