Senior cyber leadership on a fractional, retained basis.

Virtual CISO (vCISO) — 24×7 managed services operations bridge with analyst wallboards, MAST Consulting Group

Overview

An experienced CISO embedded with your executive team on a fractional basis — typically 2 to 8 days per month — covering cyber strategy, board reporting, regulator liaison, third-party risk, incident command and security budget ownership.

In depth

A four-layer view of this service.

Context, scope, delivery and impact — written for buyers, boards, auditors and search engines alike.

Layer 01 — Context

Context & Why It Matters

01

Most mid-market and many large enterprises cannot justify or attract a full-time Chief Information Security Officer of the calibre regulators, customers and boards now expect.

  • A fractional or virtual CISO (vCISO) delivers the senior leadership, regulator credibility and board presence of an executive CISO on a 2- to 8-days-per-month basis, ideal for organisations between $50M and $2B revenue or those scaling toward IPO, regulator licensing or enterprise expansion.
Layer 02 — Scope

Scope & What It Covers

02

Coverage includes cyber strategy and target operating model, board and audit committee reporting, regulator liaison (CBUAE, SAMA, NCA, RBI, SEBI, DFSA, ADGM, DESC), third-party and supply-chain risk, security budget ownership and defence, M&A cyber due diligence, security architecture decisions, vendor selection and contract negotiation, incident command and breach response leadership, and mentoring of internal security managers.

Layer 03 — Approach

Our Approach & Delivery

03

An experienced CISO (15–25 years, CISSP/CISM/CRISC, prior CISO or deputy CISO roles in regulated industries) is matched to your sector, scale and culture.

  • Monthly steering with the executive team, quarterly board pack, weekly check-ins with the security lead, on-call during incidents, and a documented 12-month roadmap.
  • Engagement scales up during regulator submissions, audits, incidents or strategic initiatives.
Layer 04 — Impact

Business Impact & Outcomes

04

Clients gain board-credible cyber leadership at 25–40 percent the cost of a permanent hire, faster decisions, defensible regulator and auditor relationships, and a continuously refreshed security strategy.

  • Many vCISO engagements either convert to a permanent hire mentored by the vCISO or run multi-year as a long-term operating model.

FAQ

Frequently asked questions.

What is the typical engagement size?+

Most clients start at 2 to 4 days per month, scaling to 6 to 8 days during regulator submissions, incidents or M&A activity.

Do you provide 24×7 cover?+

Yes — vCISO retainers include on-call escalation for major incidents and breach response.

How is a vCISO different from a consultant?+

A consultant delivers a project. A vCISO holds the CISO accountability — owns the strategy, board narrative, regulator relationship and incident command across an open-ended retainer.

Who is our vCISO?+

A named senior practitioner with 15+ years of CISO or Head-of-Security experience in your sector. Same person every month — no rotating account team.

Can we hire your vCISO into a full-time role?+

Yes. Several clients have converted vCISOs into permanent hires after 9 to 18 months. We support the transition with no buy-out fee.

Will a vCISO replace our security team?+

No — the vCISO leads and orchestrates your existing team (or MSSP). They provide leadership, governance and external credibility, not hands-on engineering.

Do you support board and audit committee meetings?+

Yes — preparation, attendance and follow-up across the quarterly audit committee, board risk committee and ad-hoc cyber forums.

What if our needs grow mid-engagement?+

Days flex up monthly. We have moved clients from 2 days/month to a full-time interim CISO during regulator events, M&A and major incidents.
