Experienced security leaders with hands-on delivery experience across governance, cyber resilience & compliance programmes.
Access to penetration testers, governance specialists, cyber incident responders, & compliance consultants.

A virtual CISO provides executive-level cyber security leadership on a flexible basis, helping organisations improve resilience, governance, and compliance while aligning security with business priorities.
Also referred to as CISO as a Service or outsourced CISO, the model gives organisations access to the same strategic capability as a full-time Chief Information Security Officer, delivered fractionally, at a fraction of the cost.
The role covers everything a traditional CISO would own: developing and maintaining your security strategy, managing cyber risk, overseeing compliance obligations, and providing leadership during incidents. The difference is structural.
A vCISO works across your organisation as a senior advisor and programme lead, without the overhead of a permanent hire.
Most organisations that engage a vCISO are not in crisis. They have reached a point where security complexity has outgrown internal capability, compliance obligations are increasing, or the board needs clearer oversight than anyone inside the business can currently provide. Reasons for engaging a vCISO may include:
Many organisations recognise the importance of strong cyber security leadership but struggle to justify the cost of a full-time Chief Information Security Officer (CISO). A vCISO service provides access to experienced cybersecurity leadership on a flexible basis, helping organisations strengthen their security posture, manage risk, and meet compliance requirements without the overhead of a permanent executive hire.
Hiring an experienced CISO can be expensive and time-consuming. A vCISO gives you access to board-level cybersecurity leadership at a fraction of the cost, allowing you to scale support based on your needs. Whether you require ongoing strategic guidance, support for a compliance project or help responding to emerging risks, you only pay for the expertise you need.
A vCISO brings experience gained across multiple industries, regulatory environments and security programmes. Rather than relying on a single perspective, organisations benefit from proven approaches, practical lessons learned and exposure to current cybersecurity challenges across different sectors.
A vCISO helps organisations develop a clear cybersecurity strategy aligned with business objectives. This includes identifying and prioritising risks, establishing governance frameworks, developing policies and implementing controls that improve resilience against evolving threats. The result is a stronger security posture and greater confidence in your organisation’s ability to manage cyber risk.
Navigating frameworks such as ISO 27001, GDPR, NIST CSF and Cyber Essentials can be challenging without specialist guidance. A vCISO helps interpret requirements, identify gaps, prioritise improvements and demonstrate progress to customers, auditors and regulators. This reduces compliance risk while supporting wider business objectives.
An external vCISO provides an objective assessment of your current security programme. Free from internal politics or existing assumptions, they can identify overlooked risks, challenge ineffective processes and recommend practical improvements based on real-world experience.
As your organisation evolves, your security requirements will change. A vCISO service can scale alongside your business, providing additional support during periods of growth, compliance initiatives, security incidents or digital transformation projects. This flexibility ensures you always have access to the right level of cybersecurity leadership when you need it most.

A vCISO, or virtual Chief Information Security Officer, is an outsourced cyber security leader who gives your organisation senior security guidance without joining as a full-time employee. A vCISO helps set your cyber security strategy, manage risk, support compliance, brief leadership teams and guide your internal IT team.
CISO as a Service typically includes security leadership, policy development, risk management, compliance support, incident response guidance, audit preparation, and ongoing cybersecurity advisory services.
A vCISO is usually more cost-effective than hiring a full-time CISO because you only pay for the level of support you need. A full-time CISO comes with salary, recruitment costs, benefits and long-term commitment. A vCISO service can be delivered on a fractional, retained or project basis, making it easier to match the cost to your organisation’s size, risk profile and goals.
A vCISO can lead cyber security strategy, assess risk, develop security policies, support ISO 27001 or GDPR compliance, review suppliers, guide incident response planning, brief the board and help prioritise security improvements. They can also work with your IT team to turn recommendations into practical actions.
Yes. Many SMEs need senior cybersecurity guidance but do not require a permanent in-house CISO. A virtual CISO provides flexible expertise aligned to the organisation’s size, risk profile, and growth plans.
A vCISO works alongside your existing IT team rather than replacing it. They provide senior direction, help prioritise work, support technical decision-making and give leadership teams clearer visibility of cyber risk. This gives your IT team strategic support while keeping day-to-day knowledge inside the business.
Yes. A vCISO can support ISO 27001 readiness by helping establish governance frameworks, policies, risk management processes, and ongoing Information Security Management System oversight.
You should consider vCISO services if your organisation needs senior cybersecurity leadership but is not ready to hire a full-time CISO. Common triggers include client security requirements, ISO 27001 projects, board concerns about cyber risk, rapid growth, regulatory pressure, security incidents or an IT team that needs more strategic support.
Yes. A vCISO can help prepare your organisation for Cyber Essentials and Cyber Essentials Plus through gap analysis, remediation guidance, policy improvements, and audit preparation.
