How we can work together

Security assessments

Risk- and compliance-based assessments against recognised frameworks such as ISO 27001, NIST CSF, DORA and NIS2. You learn where you stand and what matters most, and you get a prioritised roadmap to close the gaps.

  • Gap analysis against your target framework
  • Risk-ranked findings
  • Practical remediation roadmap

Design & implementation

End-to-end projects that take a security capability from architecture to production: XDR, SIEM/SOAR, email security or mobile threat defence, across hybrid-cloud environments.

  • Solution architecture & design
  • Deployment, integration & tuning
  • Documentation & handover

Advisory & support

Ongoing guidance and hands-on help for your team, from architecture reviews and detection tuning to a trusted second opinion on the hard calls.

  • Architecture & control reviews
  • SOC & detection improvement
  • On-call expertise for your team

Frequently asked questions

What size of organisations do you work with?

Organisations of every size, from small and medium-sized enterprises to large multinational enterprises. The approach scales to your size, maturity and budget.

Do you work remotely, on-site, or both?

Both. Most work can be delivered remotely from anywhere in the world, and I’m happy to work on-site when an engagement calls for it.

How does a typical engagement start?

With a conversation. Send me a message on LinkedIn with a short description of your challenge, and we’ll set up a call to explore scope, goals and timelines.

Can you help us prepare for DORA, NIS2 or ISO 27001?

Yes. I have implemented an ISO 27001 information security management system (ISMS), and that experience carries over to other frameworks and regulations such as DORA, NIS2 and the NIST CSF. I study each one in the context of your organisation, so the controls fit how you actually operate.

Do you work with our existing security tools, or recommend new ones?

That depends on what an initial assessment and gap analysis show. Often the best result comes from getting more out of the tools you already have. Where there are genuine gaps, I’ll recommend options that fit your environment and budget.

Do you offer short-term projects, ongoing support, or both?

Both. Engagements can be a defined, short-term project such as an assessment or implementation, or ongoing advisory and support, whichever suits your needs.

How do you handle confidentiality and access to sensitive data?

Confidentiality is fundamental to my work. I’m glad to sign NDAs and any other confidentiality agreements you require. When a project ends, I securely delete any data collected during it that is confidential, sensitive or covered by the GDPR.

Which time zones do you cover?

I fully cover European and African time zones. For clients in the Americas, I prefer US Eastern or Central time.

How is pricing structured?

Pricing depends on the scope, duration and type of engagement. Get in touch and we can discuss an arrangement that works for you.
