Your business may need experienced security leadership before it needs a full-time CISO. We provide fractional support to help set priorities, coordinate action and explain security risk to decision-makers.
A fractional CISO gives a growing company an experienced security decision-maker without pretending that a part-time adviser is a 24-hour SOC. We help establish a realistic security roadmap, review material risks and coordinate agreed improvement work. The role is tailored to your size, technology estate, existing IT provider and decision-making structure.
The usual buyer is a founder, COO, CTO, board member or head of engineering at a UK or European SaaS, AI or professional-services company with 20–300 people. The organisation has security responsibilities distributed across engineering, IT and operations, but no senior person with enough time or independence to join those threads. It may already have a capable managed service provider; what is missing is prioritisation, challenge and accountable reporting.
This model is also useful for a company between funding rounds, integrating an acquisition, building a regulated product or preparing to hire its first permanent security leader. We can provide a defined transition period, co-source with an existing security manager or fill a specific governance gap while recruitment continues.
Searches for a vCISO often begin after an enterprise prospect sends a 200-question security questionnaire, an insurer requests a formal risk review, a board asks why critical findings remain open, or an incident exposes that nobody owns the response plan. Other triggers include a new US or EU market, an ISO 27001 or SOC 2 target, rapid use of generative AI, a material supplier change or a customer asking for named security leadership.
We start with the decision the business needs to make. A buyer should not commission a generic “security strategy” when the immediate need is a risk acceptance decision, a control-owner plan, or an honest answer to a customer’s evidence request.
Leadership wants to know the top risks, their likely business impact, what has changed since the last report and which decisions require budget. Customers ask who owns security, how incidents are escalated, where data is hosted, how suppliers are assessed and whether access, vulnerability and continuity controls operate. Auditors ask for evidence that management sets objectives, reviews performance, tracks corrective action and does not simply rely on an MSP’s statement of work.
A useful CISO function turns these into one coherent view: a risk register with treatment decisions, a roadmap tied to business outcomes, control owners and an evidence index. It does not turn every low-risk issue into an emergency or hide uncertainty behind a maturity score.
We perform a structured first review of your organisation, critical services, cloud architecture, identity model, suppliers, existing policies, incidents and customer commitments. We interview technical and business owners, sample evidence and agree a concise risk taxonomy. The output is a sequenced programme rather than a long list of controls that cannot be resourced.
Ongoing support can include monthly risk and roadmap meetings; board or investor reporting; security input to product and procurement decisions; supplier and customer security reviews; policy and exception governance; incident tabletop exercises; vulnerability and penetration-test oversight; certification readiness; and coordination between engineering, IT, privacy and legal teams. We can chair a security steering group, but management keeps authority to accept risk and allocate resources.
Typical deliverables include a current-state and target-state assessment, a board-ready risk report, a maintained risk register, a 90-day and 12-month security roadmap, a responsibility matrix, a control and evidence index, a supplier-risk review template, incident escalation and tabletop records, customer questionnaire responses, and management-review minutes. Where a standard is in scope, we map the plan to relevant ISO 27001, SOC 2, GDPR or customer requirements without claiming that a roadmap is a certification.
Each action records the owner, dependency, due date, acceptance evidence and residual risk. For example, “improve access control” becomes an agreed joiner/mover/leaver workflow, a privileged-access review, an owner in the identity team and a dated export showing completion. That level of specificity is what lets a board see progress and an auditor test operation.
A diagnostic takes two to four weeks, including stakeholder interviews, evidence sampling and a prioritisation workshop. A first 90-day programme then focuses on urgent exposure, accountability and customer-facing evidence. Ongoing retainers commonly run for three to twelve months with a weekly or fortnightly operating session and a monthly leadership report. A lighter advisory cadence is possible when an internal security lead owns delivery.
Incident advisory coverage, response times and out-of-hours availability must be explicitly agreed. A fractional CISO retainer does not automatically include managed detection, 24-hour monitoring, forensic investigation or legal breach response; those specialist services are separately scoped.
A typical engagement might turn an unresolved customer request into a signed data-flow and subprocessor review, an owner-approved risk treatment plan and a reusable evidence pack. In another case, a SaaS team can move from quarterly informal access checks to a recorded review of privileged roles, an exception process and removal evidence. During an ISO 27001 programme, the CISO role can keep control owners moving while an IT internal audit independently tests selected controls.
Yes. Responsibilities, decision rights and escalation routes are agreed so security leadership supports the delivery teams without duplicating their work.
A fractional CISO provides independent risk leadership: setting priorities, advising management, governing security controls and translating technical exposure into decisions and evidence.
That depends on your scale and evidence needs. The engagement can work with existing tools or a simpler evidence structure before recommending software.
No. Leadership remains responsible for decisions and resources; we provide advice, challenge and programme support with clear ownership.
