Job Description

Cyber Security Delivery Manager | £80-90k | Portsmouth (Hybrid) | SC Clearance Eligibility essential

Are you a senior cyber security professional who can lead from the front - advising at board level one day and getting hands-on with a security architecture review the next?

We're recruiting on behalf of a well-regarded cyber security consultancy based in Hampshire. They work with a range of clients on complex, meaningful security challenges - and they're looking for an experienced Cyber Manager to join the senior team.

This isn't a purely strategic role. You'll lead engagements, grow client relationships, and help shape the direction of the business - but you'll also roll your sleeves up when the work demands it.

Salary: £80,000-90,000

Package: Gym, private medical insurance, company pension, work from home flex

Working Structure: Hybrid remote in Portsmouth (2 days onsite)

Security Clearance: Active or Eligible for SC clearance.

The Role:

As Cyber Security Delivery Manager, you'll take ownership of client engagements from start to finish, covering risk assessments, security architecture reviews, policy development, incident response planning, and governance work. You'll be the senior point of contact on engagements, ensuring quality and consistency across everything that goes out the door.

What You'll Be Doing:

  • Leading end-to-end cyber security engagements across advisory and hands-on delivery
  • Managing multiple projects simultaneously, ensuring delivery quality and client satisfaction
  • Building and maintaining strong relationships with clients, including at CISO and board level
  • Leading proposals and bids, contributing to go-to-market strategy and service development
  • Supporting and developing junior and mid-level consultants through active mentoring
  • Putting sensible operational processes in place and keeping day-to-day delivery on track
  • Contributing to hiring decisions as the team grows

What You'll Need:

  • Significant experience delivering cyber security projects in a consultancy or professional services environment
  • Strong technical knowledge across core cyber domains - risk management, security architecture, governance, assurance, or incident response
  • CISSP, CISM, or equivalent professional certification
  • A proven track record of leading teams and managing senior client relationships
  • The ability to communicate complex security topics clearly to both technical and non-technical stakeholders
  • Eligibility to obtain or active SC (Security Clearance)
  • Self-motivated, decisive, and comfortable operating with a high degree of autonomy

Desired but not essential:

  • Experience across multiple disciplines such as GRC, penetration testing, SOC, cloud security, or OT security
  • Familiarity with frameworks including NIST, ISO 27001, CAF, or Cyber Essentials
  • Experience working with government, defence, or critical national infrastructure clients
  • Additional certifications such as Crest, OSCP, or NCSC Certified Professional

If this sounds like the right next step, apply now or get in touch for a confidential conversation. Candidates must be eligible to work in the UK and able to obtain Security Clearance.
