Virtual CISO (Chief Information Security Officer) as a Service

As cyber threats increase in frequency and sophistication, many organisations need senior security leadership — but not every business requires (or can justify) a full-time Chief Information Security Officer (CISO).

VMGroup’s Virtual CISO (vCISO) service provides flexible, senior-level cybersecurity leadership to organisations across Ireland, helping you build resilience, meet regulatory obligations, and reduce risk, without the overhead of a permanent hire.

We offer scalable support ranging from Virtual CISO, Security Manager, Consultant, and Analyst roles, allowing you to extend your internal capabilities at the level that best suits your organisation.

What is a Virtual CISO?

A Virtual CISO is an outsourced senior cybersecurity leader who provides strategic direction, governance, and oversight for your organisation’s information security programme.

Your vCISO acts as a trusted advisor to senior management and the board, helping you:

Understand your current security maturity and risk exposure
Define a clear cybersecurity strategy and roadmap
Align security with business objectives
Meet regulatory and compliance obligations (GDPR, DPA 2018, NIS/NIS2, ISO 27001, sectoral regulations)
Build internal capability across technology, people, and process

Why Organisations Use vCISO Services

Organisations typically engage a Virtual CISO when:

They do not have an in-house security leader
The existing IT team lacks specialist security expertise
They need support preparing for regulatory audits or certifications
They are responding to incidents such as ransomware, phishing, or data breaches
They must comply with GDPR, DPC expectations, NIS/NIS2, ISO 27001, DORA, or sector-specific regulations
They want to professionalise governance without hiring a full-time executive

Flexible Resourcing Model

VMGroup provides tiered security leadership, depending on your needs:

Virtual CISO – Strategic leadership, board engagement, governance, and executive reporting
Security Manager – Operational ownership of the security programme and roadmap
Security Consultant – Specialist expertise for projects, audits, or improvements
Security Analyst – Day-to-day operational support, monitoring, documentation, and implementation

This allows organisations to scale security capability up or down as business and risk evolves.

Virtual CISO for OT Security (Operational Technology)

For organisations operating industrial environments, including manufacturing, pharma, utilities, food production, and critical infrastructure, cybersecurity risk extends beyond IT into Operational Technology (OT).

OT environments introduce unique challenges:

Legacy systems not designed for security
Safety-critical operations
Limited patching windows
Convergence of IT and OT networks
Increased targeting by ransomware and nation-state actors

VMGroup provides specialist vCISO services for OT security environments, bridging the gap between engineering, IT, and executive leadership.

We support organisations with:

OT security governance and accountability structures
IT/OT risk assessments and segmentation strategies
Development of OT-specific security policies and procedures
Alignment with frameworks such as IEC 62443, NIST CSF, and NIS/NIS2
Secure remote access design for vendors and engineers
Incident response planning for production-impacting cyber events
Business continuity planning for OT disruptions
Supplier and integrator risk management
Board-level reporting on cyber risk to operations and safety

Typical OT Use Cases

Manufacturing organisations facing increasing ransomware risk
Pharmaceutical companies with validated production environments
Organisations subject to NIS/NIS2 critical infrastructure requirements
Facilities integrating IIoT, automation, or smart factory technologies
Businesses experiencing convergence between corporate IT and plant networks

Deliverables You Can Expect

Security maturity assessment and gap analysis
