Cyber Security Account Manager in City of London

If you’re a cyber Account Manager who enjoys growing relationships, not just managing renewals, and wants ownership that goes beyond a traditional “farmer” role, this one’s worth a look.

I’m hiring for a high-growth, PE-backed cyber security services provider (MSSP) with a clear remit: own and grow customer relationships, expand service adoption, and convert partner-, vendor-, and marketing-led new opportunities through a consultative, solutions-led sales approach.

This is an Account Manager role with genuine responsibility, blending account growth, expansion, and structured net-new opportunity conversion within an award-winning Microsoft and cyber-focused MSSP.

The role

You’ll take ownership of a portfolio of customers, responsible for retention, expansion, and long-term value creation, while also nurturing new opportunities introduced through partners, vendors, and inbound marketing. This is not a pure renewals role. You’ll be trusted to build account plans, identify new use cases, expand service adoption, and develop relationships across multiple stakeholders, as well as progress warm new-logo opportunities through to first sale.

Key responsibilities (what you’ll actually do)

• Account ownership and growth

• Own and develop a portfolio of enterprise and mid-market customers
• Land and expand accounts by converting initial engagements into multi-service, long-term relationships
• Build and execute account plans focused on retention, upsell, and cross-sell
• Grow ACV through renewals, service expansion, and deeper stakeholder engagement

• Sell across a blended cyber security portfolio, including managed security services and professional services
• Lead outcome-focused conversations with senior stakeholders
• Position cyber solutions in the context of business risk, compliance, and resilience
• Act as a trusted commercial partner rather than a transactional seller

• Progress warm new-logo opportunities generated via partners, vendors, and marketing
• Qualify, scope, and convert inbound opportunities through structured discovery
• Build early-stage relationships and take ownership through to first win

• Work closely with Microsoft and cyber vendors, channel partners, and MSP relationships
• Collaborate with marketing, pre-sales, and delivery teams to progress opportunities
• Ensure opportunities are well qualified, commercially sound, and deliverable

What they’re looking for

• ~3 to 6+ years’ experience in cyber security and/or Microsoft security sales or account management
• ~ Proven experience managing and growing customer accounts within an MSSP, Microsoft Partner, or managed services environment
• ~ Comfortable balancing account growth with partner-led and inbound new opportunity conversion, roughly 50/50
• ~ Strong understanding of sales discipline, qualification, and forecasting
• ~ Confident communicator with strong relationship-building skills

Cyber security sales experience would be a nice to have, including:

• Managed security services such as MDR and XDR
• Threat detection and response
• Identity and Access Management (IAM)
• Data governance and data security
• Ability to position solutions against business risk and measurable outcomes

Practical requirements

• Able to travel to London and/or Maidenhead HQ 3 to 4 times per month
• Comfortable working in a hybrid, relationship-led sales environment
