About Cydefen

A Polish cybersecurity partner playing the long game

We build security programs that survive an audit, an incident and a team change. From awareness training to a full ISMS — one team, one accountability.

Our values

How we work

Practice over theatre

We do not sell fear or template PDFs. Every recommendation is actionable, costed and anchored in your business context.

People as first line

74% of breaches start with a human. We treat training and simulations as a technical control — measurable and repeatable.

Evidence, not promises

Everything we deliver ends in a pack your auditor and regulator will accept. Whether it is a pentest or a full ISMS.

Local market fluency

UKNF, KNF, NASK, CSIRT, KSC — we understand the Polish regulatory ecosystem and can talk to every one of those stakeholders.

Enterprise rigour

Methodologies: OWASP, PTES, OSSTMM, TIBER-EU. Certifications: OSCP, OSWE, OSEP, CISSP, CISA, ISO 27001 Lead Implementer / Lead Auditor.

Long-term partnership

Most of our clients stay after the first project — retainers, ISMS maintenance, annual testing, incident support.

Our approach

From first conversation to long-term partnership

  1. 01

    Understand the business

    We start with your business model, critical processes and risk appetite — not with a vulnerability scanner.

  2. 02

    Prioritise

    Not everything at once. We pick the controls with the highest return and a realistic timeline.

  3. 03

    Deliver

    One team delivers the technical, human and compliance work. No finger-pointing between subcontractors.

  4. 04

    Maintain

    We stay after go-live — annual reviews, new controls, regulator updates, audit support.

Let's talk

30 minutes, no obligation. We understand where you are and propose a sensible path forward.
