Product cybersecurity

Fractional Product Security Advisor

A senior advisor who knows the CRA and IEC 62443, a few days a month, without a full-time hire.

Best forOEMs that need direction, not a whole programme: a product line to keep compliant, an audit coming, questions from customers and engineers.

Service overview

Senior judgement when you need it, not a head count

Not every company needs the full programme. Many have engineers who can build, a process that mostly works and a certificate to keep. What they lack is one person who has done it before and can say what matters and what does not.

A fractional advisor is that person: part of your team for a fixed number of days a month, on call between them. They set direction, review what your team produces, sit in the audit and answer the questions your customers and engineers ask. Some call it a fractional CISO for the product line; we call it an advisor, because that is the job.

Everything the advisor does goes into your documents and your tickets, so what was built stays with you when the engagement ends.

What the advisor does

  • Direction on the CRA, RED DA, IEC 62443 and what your customers ask for
  • Interim ownership of product cybersecurity until you assign or hire the owner
  • Threat model for a product or a release
  • A single policy, procedure or guide when that is all you need
  • Review of documents and evidence before an audit, and support on the day
  • Answers to customer security questionnaires and tender requirements
  • SBOM, vulnerability handling and update process set-up
  • Questions from your engineers, answered as they come up

Ways to engage

Three ways to have an advisor

Same people as our programmes, without the programme. Start small, scale up before an audit, stop when the need passes.

A few days a month

For direction and a steady pair of eyes

The advisor joins your reviews on fixed days and is on call between them. The number of days can change each quarter.

A bank of days

For an audit, a tender or a threat model

A block of days used when something comes up. No monthly commitment.

One task

For a single piece of work

A fixed scope: one policy, one threat model, one audit day, one customer questionnaire.

Our approach

Engagement methodology

The steps of the engagement, built around how your team already designs, builds and releases the product.

Step 01

Agree the ask

One conversation to settle what you need help with, how many days a month, and who on your side the advisor works with.

Step 02

Work inside your team

The advisor joins your reviews, reads your documents, sits in your audits and answers your questions, on the agreed days and on call between them.

Step 03

Leave it with you

Everything goes into your documents and your tickets. When you hire in-house or the need passes, you keep what was built.
