VIRTUAL CISO
(vCISO)

Security leadership without the full-time cost.

A board asking cyber questions your IT team cannot confidently answer. A client, funder or insurer demanding evidence of security governance. A certification deadline with nobody senior to lead it. These are not IT problems. They are security leadership problems. Starkhorn solves them through a virtual CISO: experienced, independent security leadership on a part-time or retained basis, accountable for your posture and speaking the language your board, auditors, regulators and insurers actually need. No software commissions. No referral fees. Just clear advice and accountable delivery, framed around NIST CSF, ISO 27001 and Cyber Essentials rather than infrastructure jargon.

The vCISO Difference

Security is either protecting your organisation or quietly exposing it

In most organisations, security sits outside the leadership conversation entirely. Controls drift unchecked. Certifications stall because nobody senior owns them.

The board gets vague answers on cyber risk, or no answers at all. And every quarter, the gap between the assurance stakeholders expect and the assurance you can actually evidence widens. We bring independent security leadership built for boards, auditors, regulators and insurers.

Every assessment, every recommendation, and every board report is framed in risk reduced, assurance gained, and compliance achieved, not infrastructure jargon.

Charity and Non-Profit Security Leadership

Alzheimer’s Society and Age UK

Current fractional Associate Director of IT at Alzheimer’s Society, providing senior technology and security leadership to one of the UK’s most trusted charities, with prior work at Age UK.

Responsible for protecting sensitive beneficiary and donor data, strengthening governance, and giving trustees clear assurance on cyber risk.

The Security Assessment

Security posture assessment designed for boards

The first step in every engagement.

Within the opening weeks, we map your security estate, assess your posture against NIST CSF and ISO 27001, benchmark your controls, evaluate your team’s capability, and deliver a board-ready report with a prioritised roadmap, all framed in risk and assurance.

This assessment becomes the foundation for everything that follows: framework alignment, certification readiness, incident preparedness, and long-term security strategy.

What Boards Get

Every cyber risk mapped and challenged

Not a technical audit.

A board-level assessment that identifies specific risks, control gaps, and compliance shortfalls, all presented in plain language your board, auditors, regulators and insurers can act on.

Most organisations carry security risks they cannot see and cannot evidence. We find them, quantify them, and show you how to close them.

For Certification Readiness

Rapid path to ISO 27001 and Cyber Essentials

Facing a certification deadline, your team needs answers fast.

Which controls already meet the standard. Which gaps must close first.

Where the evidence sits. Where the quick wins are.

We translate the requirements of ISO 27001, Cyber Essentials and Cyber Essentials Plus into a clear plan that de-risks the timeline and gets you certification-ready without wasted effort.

Insurer and Auditor Readiness

Security that satisfies insurers and auditors

An insurer or auditor will interrogate your security estate: control maturity, cyber posture, supplier dependencies, data quality, and incident readiness.

We identify everything that could be flagged as a weakness and build the remediation plan before the review begins. The goal: a security programme that lowers your cyber insurance premiums and passes audit instead of failing it.

Board Reporting

Board and trustee grade language

Every finding framed in risk reduced, assurance gained, compliance achieved, and stakeholder confidence. RAG-scored across key domains with a prioritised roadmap at 30 days, 90 days, and 12 months.

Presented to your board in person, not emailed as a PDF. No technical jargon. No infrastructure complexity. Just clarity your board, auditors, regulators and insurers can trust.

The Cost of No Security Leadership

A single breach or failed audit can cost far more than a year of vCISO support: lost contracts, higher insurance premiums, regulatory penalties, and the time your team loses cleaning up an incident nobody led.

The organisations that stay secure are the ones that bring security leadership in before the incident, not after it.

Every quarter without independent security oversight is a quarter where controls drift, certifications stall, and your exposure grows.

Working with Your Board

Security decisions with measurable assurance

Cyber Risk Under Control

Not a technical audit. A board-level assessment that identifies specific risks, control gaps, and compliance shortfalls, all presented in plain language. Most organisations carry security risks they cannot see and cannot evidence. We find them, quantify them, and show you how to close them.

Certifications Achieved

Stalled certification programmes are where security credibility goes to die. We identify which controls already meet the standard, which gaps must close, where the evidence sits, and how to reach ISO 27001 or Cyber Essentials Plus on time, not eventually.

A Board That Trusts the Security Story

RAG-scored reporting across key domains with a prioritised roadmap at 30, 90, and 365 days. Presented to your board in person, in the language of assurance, risk reduced, compliance achieved, and stakeholder confidence. Not emailed as a PDF. Not written in jargon.

Assurance Auditors and Insurers Will Accept

Security posture evidenced. Supplier dependencies mapped. Data quality assured. Incident readiness demonstrated. Everything an auditor, regulator or insurer will interrogate, assessed, addressed, and documented before they arrive. Security becomes a strength on the record, not a red flag.

Common questions

Virtual CISO FAQs

Why use a virtual CISO rather than a permanent hire?

Because most organisations cannot justify a full-time CISO, yet security is either protecting the organisation or quietly exposing it. You get experienced, independent security leadership tied to real assurance, without adding permanent cost.

When should security leadership come in?

As early as you can. Before an incident it sets strategy and closes gaps. During certification it controls the programme and gets you over the line. Through the year it keeps controls aligned to the standard. Approaching an audit, insurer review or tender it makes sure the security story stands up to scrutiny.

How do you tie the work to assurance?

Every recommendation is framed as outcome: risk removed, controls met, compliance achieved. Many engagements find quick wins in the first weeks, and the larger gains show up as a credible programme, lower insurance premiums, and a security story that passes audit.

Can you support charities and non-profits?

Yes. Non-profits hold highly sensitive data and face the same threats as commercial organisations, often with fewer resources. Starkhorn works with charity clients, including a current engagement at Alzheimer's Society, and understands the governance, budget and stakeholder expectations specific to the sector.

How is this different from a consultancy or an MSP?

A consultancy delivers a report and leaves; an MSP has an interest in selling you more of its own tooling. This is independent, accountable security leadership, with no software commissions and no referral fees, accountable for the outcome and with nothing to sell you but the result.

Two Ways to Start

You already know something isn't right. The only question is what you do next.

What is a virtual CISO (vCISO)?

A virtual CISO (vCISO) is an experienced Chief Information Security Officer engaged on demand, part time or for a fixed period rather than as a permanent hire. The role delivers security strategy, governance, risk management and board level assurance, giving organisations senior cyber leadership without the cost of a full time executive.

Virtual CISO and CISO as a service: security leadership, not a SOC

Starkhorn's virtual CISO services and CISO as a service offering mean security leadership and governance: strategy, risk, policy, compliance and board reporting. This is information security leadership, not managed security operations. Starkhorn does not run a SOC, sell tooling or staff a 24/7 monitoring desk. The vCISO directs and assures your security, working with whichever operational providers you already use.

Frequently asked questions

What does vCISO stand for?

vCISO stands for virtual Chief Information Security Officer. It is an experienced security leader engaged on demand, part time or for a fixed period, rather than as a permanent full time hire. The role covers security strategy, governance, risk and assurance, giving organisations senior cyber leadership without the cost of a salaried executive.

What does a virtual CISO do?

A virtual CISO sets and runs your security strategy: governance, risk management, policy, compliance, board reporting and incident readiness. They own the security roadmap, mature your controls and act as the senior point of accountability for cyber risk. Starkhorn delivers security leadership and governance, not a managed SOC, tooling or day to day operations.

What is the role of a vCISO?

The vCISO role is senior security leadership: owning cyber risk on behalf of the board, defining the security strategy and governance framework, and assuring controls against frameworks such as ISO 27001 or Cyber Essentials. They translate technical risk into commercial decisions, brief executives and trustees, and build lasting in house security capability rather than running operations.

What is a vCISO vs CISO?

A full time CISO is a permanent salaried executive carrying fixed cost and notice periods. A vCISO delivers the same strategic security leadership on demand, scaled to your need and budget, typically part time or for a defined engagement. For many mid sized and non profit organisations a vCISO gives board level security ownership without a full executive headcount.

What is the difference between a virtual CISO and a fractional CISO?

The terms overlap heavily and are often used interchangeably for part time security leadership. Fractional usually describes an ongoing share of a leader's time across clients, while virtual CISO emphasises remote, on demand engagement. Interim CISO covers a full time fixed term gap. For a fuller comparison of engagement models, see our interim versus fractional guide.

How much does a virtual CISO (vCISO) cost in the UK?

UK virtual CISO cost is usually a monthly retainer or day rate scaled to scope, sector and risk, rather than a fixed list price. A vCISO is materially cheaper than a permanent CISO salary plus on costs, because you buy only the leadership time you need. See our pricing page for how Starkhorn structures retainers and day rates.

Can AI replace a CISO?

No. AI can accelerate detection, triage and reporting, but it cannot own cyber risk, set strategy, make accountable judgement calls or answer to a board. The CISO role is leadership, governance and decision making under uncertainty. A vCISO uses AI as a tool while remaining the named human accountable for your security posture.
