Interim and fractional security leaders, on demand

Interim and fractional CISOs, heads of security, security architects and identity specialists, embedded into your organisation for as long as you need them, across the UK, Europe and the US. Tell us what you need and we'll typically share profiles within 48 hours.

When organisations call us

  • Your CISO or head of security leaves: An interim security leader keeps strategy, risk ownership and board reporting on track while you recruit, so there's no gap in accountability.
  • You need senior security leadership, not a full-time CISO: A fractional CISO for a few days a month sets strategy, owns the risk register, prepares you for audits and certifications, and reports to the board.
  • A programme needs specialist depth: Security architects for a cloud migration, identity and access management specialists for an IAM or PAM programme, or offensive security to validate controls before go-live.
  • A regulator, auditor or incident has raised the stakes: Experienced security leaders who can step in quickly, steady the response and put a credible plan in front of your board.

  • Profiles within 48 hours: We typically share profiles within 48 hours, drawn from our dedicated security practice and network. You meet them before anything is agreed.
  • Embed and deliver: Your security leader or specialist works as part of your team, with EP managing the engagement. Scale up, scale down or extend as your needs change.
  • Transition: When the work is done, we hand over cleanly, or help you hire permanently if the role should stay.

Frequently asked questions

How quickly can you provide a CISO or security specialist?

We typically share profiles within 48 hours of understanding your requirement. Start dates then depend on the individual's availability, your onboarding and any clearance needed.

What does a fractional CISO do?

A fractional CISO provides senior security leadership on a part-time, ongoing basis. They set security strategy, own the risk register, oversee compliance and certifications, guide incident readiness and report to the board, without the cost of a full-time hire.

What is the difference between an interim and a fractional CISO?

An interim CISO works full time for a defined period, often covering a vacancy or a critical programme. A fractional CISO works part time on an ongoing basis, suiting organisations that need senior leadership but not a full-time role.

How much does a fractional or interim CISO cost?

It depends on seniority, sector, scope, clearance and time commitment. We will give you clear rate guidance at the start of the conversation, before you commit to anything.

Can you provide SC or DV cleared security professionals?

Yes. We have a strong network of SC cleared security professionals and DV cleared professionals available, built through over five years of supporting UK government.

Do you provide identity and access management specialists?

Yes. Identity and privileged access management is a core specialism of our security practice, from IAM architects and programme leads to hands-on engineers.

Do you provide security leaders outside the UK?

Yes. We place and embed security leaders and specialists across the UK, Europe and the US, both on-site and remotely.
