Cybersecurity Sales Specialist in London

As Cybersecurity Sales Specialist, you’ll help grow cybersecurity revenue across Charterhouse’s Core Services division.

Working closely with account managers, technical specialists and partner teams, you will take ownership of assigned cybersecurity opportunities from discovery through to close and manage customer relationships where agreed.

The role requires sound commercial judgement, clear ownership and a collaborative approach to creating profitable growth.

You will sell across both public sector and commercial customers, typically organisations of 500 seats and above.

Our security portfolio spans Hybrid Mesh network security, MDR and SOCaa S, workplace security, AI security and threat management.

It is supported by strategic relationships with Check Point, Cato Networks, Fortinet, Palo Alto Networks, Rapid7 and Sentinel One, giving customers a choice of platforms and service models.

Knowing which approach fits each buyer matters, particularly where public sector customers face data-residency, framework and G-Cloud requirements.

Success in this role means retaining and expanding an agreed account base, securing annuity renewals, creating incremental security opportunities, leveraging cross-sell opportunities across the wider Charterhouse customer estate, maintaining a healthy new-logo pipeline and delivering strong, profitable margin.

Key Responsibilities

• Manage an agreed portfolio of customer accounts, maintaining strong relationships, protecting existing revenue and owning annuity renewals.
• Develop new security opportunities within your own accounts and, in partnership with the relevant account manager, across the wider Charterhouse customer base.

Identify cross-sell opportunities and introduce the appropriate Charterhouse specialists to progress them.

• Acquire true new-logo business through targeted prospecting, market mapping and account prioritisation across public sector and commercial customers.
• Lead the shaping and closing of opportunities across Hybrid Mesh network security, MDR and SOCaa S, workplace security, AI security and threat management.
• Position the right security technology and service model for each buyer, balancing business outcomes, risk, integration, scalability and operational requirements.
• Navigate public sector buying, including frameworks, G-Cloud, data-residency and security accreditation requirements, alongside faster-moving commercial deal cycles.
• Grow Charterhouse’s security presence in its strongest verticals (NHS, local government, higher education) and in growth areas such as housing associations and corporate finance, manufacturing and media.
• Build strong relationships with strategic and specialist security partner teams to generate joint opportunities.
• Drive commercial negotiations and bids, working with pre-sales, solution architects, service, legal and finance teams to deliver compelling and profitable proposals.
• Agree clear ownership and ways of working with account managers, including when you manage the customer relationship, act as the security specialist or transition ongoing ownership.
• Maintain accurate, up-to-date CRM records for account plans, prospect interactions, opportunities, pipeline stages and agreed ownership.
• Stay informed on the threat landscape, industry trends, emerging technologies and Charterhouse’s evolving solution portfolio.
