Senior Cyber Security Consultant in Portsmouth

Are you a technically strong cyber security professional ready to step into a senior role where you'll lead engagements, shape client strategy, and help grow a team around you? We're partnering with a well-regarded cyber security consultancy that punches above its size. They work with clients across a range of demanding sectors and are looking for a Senior Consultant who wants genuine ownership of their work, not just a seat at the table.

Salary: £65,000-75,000

Package: Company pension, private medical, gym, WFH

Working Structure: Hybrid, 2 days onsite (client visits)

Security Clearance: Active or eligible for SC clearance

The Role

• You'll be the senior point of contact across a portfolio of client engagements, combining hands‑on technical delivery with strategic advisory work.
• One day you might be presenting a risk‑based recommendation to a board-level stakeholder; the next you'll be knee‑deep in a security maturity review or threat assessment.
• You'll also play a key part in developing the consultants around you and identifying opportunities to grow the business.

What You'll Be Doing

• Act as the primary client contact across key accounts, managing expectations, building trust and developing long‑term relationships.
• Own the quality of engagement outputs – risk assessments, maturity reviews, strategic recommendations and client‑ready reports.
• Design security improvement plans that are proportionate, practical and tailored to each client's specific context.
• Run threat assessments, client interviews and on‑site visits as part of structured engagement delivery.
• Mentor and develop junior and mid‑level consultants, taking an active interest in their growth and output quality.
• Apply security frameworks and standards consistently to drive reliable, credible delivery.
• Spot and develop new business opportunities, contribute to proposals and help shape the consultancy's commercial direction.
• Keep risk management activity sharp across all engagements, ensuring nothing important falls through the cracks.
• Translate technical complexity into clear, confident guidance that resonates with non‑technical decision‑makers.

What You'll Need

• A strong commercial background in cyber security consultancy or professional services, with experience across sectors such as financial services, energy, telecoms or insurance.
• Technical depth across core domains including networks, infrastructure, cloud and application security.
• Hands‑on experience applying risk management frameworks in live, complex environments.
• Track record of managing client relationships at a senior level, including navigating difficult conversations and handling escalations.
• Experience leading and developing small teams, with genuine investment in others' performance and progression.
• Ability to produce polished, high‑impact written deliverables under pressure.
• Eligibility to obtain SC clearance.
• Willingness to travel to client sites in the Portsmouth area at least twice a week.

Desired

• Relevant certifications including CISSP, CISM, CRISC, ISO 27001 Lead Implementer or Auditor, CCSP, CySA+, NCSC CCP, or GIAC.
