What I do

Three things that most companies actually need when they get serious about security.

svc-01

External cybersecurity manager

I take over security leadership — governance, reporting, priorities, escalation. CISO-level accountability, no CISO budget required.

    svc-02

    Compliance and audit readiness

    I prepare you for what's coming — NIS2, ISO 27001, customer audits — with a concrete plan, not a document dump.

      svc-03

      Incident and resilience readiness

      I make sure you know what to do before something happens. Most companies find out they aren't ready during an incident.

        02 / positioning

        Who I work with

        Most of my clients come from one of four situations. See which one sounds like yours.

        op-01

        No one owns security

        You have IT, you have risk, but no one is actually responsible for cybersecurity. I step in as that person — without adding a full-time headcount.

        op-02

        IT meets OT and nobody knows the boundary

        Your factory or plant connects to your corporate network. That boundary is where most industrial incidents start. I know how to close it.

        op-03

        The board is asking questions

        Owners, investors, or the supervisory board want to understand cyber risk. I translate it into language and priorities they can work with.

        op-04

        Your customers are asking for evidence

        Questionnaires, audits, supplier requirements. I help you answer them properly — and build the substance behind the answers.

        03 / differentiator

        Why IT/OT matters

        Many companies have an OT side even if they do not call it OT: production lines, site control systems, industrial connectivity, cameras, access control, BMS, energy systems, or remote maintenance. This is where IT/OT, ISP thinking, network operations, and critical infrastructure reality meet.

            How to work with me

            Four ways to engage, depending on what you need right now.

            pkg-01

            Security Sprint

            A focused 2–4 week review. You get a clear picture of where you stand, what your biggest risks are, and what to fix first.

            pkg-02

            Ongoing leadership retainer

            I run your security function on a monthly basis — reporting, governance, stakeholder coordination, and advisory.

            pkg-03

            Transformation program

            6–12 months of structured work to build a real security function. Governance, controls, resilience, and compliance — done properly.

            pkg-04

            Executive workshops

            Half-day or full-day sessions for your leadership team on cyber risk, crisis decisions, and what security ownership actually means.

            05 / contact

            Get in touch if this is relevant

            If any of this sounded familiar, send a few lines about where things got stuck. We will quickly see whether I can help.

            disclaimer

            Security operations are rarely a one-man show. When the scope needs it, I work in a small 2-3 person setup with trusted specialists, so delivery does not depend on one person improvising alone. Any specialist involvement is handled under appropriate NDAs, verified certifications, and client-side approvals.
