Virtual CISO support that shapes stronger security decisions

One named advisor, doing the job a CISO would do — just not full time.

A CSISC vCISO plugs straight into your leadership team, giving you strategic direction, risk ownership and board-ready reporting from week one.

Lead with confidence

Set a security strategy the whole business understands and can act on, not a document that sits on a shelf.

Reduce risk exposure

Close the gaps that matter most first, guided by a prioritised, costed roadmap rather than guesswork.

Report with confidence

Give your board, investors and clients evidence of active, accountable security governance.

Advisory aligned to

NIST CSF ISO/IEC 27001 NCSC Cyber Essentials GDPR / UK DPA DORA SOC 2

The gap vCISOs close

Most breaches don't start with a firewall. They start with a missing decision-maker.

Security leadership is scarce, expensive to hire, and hard to retain — leaving a gap at exactly the point where risk decisions get made, or missed.

A full-time CISO is out of reach for most mid-market budgets and hiring timelines.
One-off audits hand you a report, then leave you to work out what to do with it.
Technical findings rarely translate into language your board can act on.
Compliance gets tackled reactively, at the worst possible time.

The CSISC vCISO Model

One accountable advisor. The full weight of a security function behind them.

Senior expertise, fractional cost — CISO-level judgement without the salary, recruitment or retention risk.
Pragmatic, not theoretical — we prioritise what reduces real risk, scoped to what you can actually action.
Fluent at board level — reporting built around risk, cost and business impact, not jargon.

The framework

Structured against five pillars, not a stack of best-practice guesses

Every engagement is organised against the same register your board will eventually see: Identify, Protect, Detect, Respond, Recover.

Bringing in a Virtual CISO gave us board-level clarity on risk that we simply couldn't get internally — without the twelve-month hiring process.
