Critical national infrastructure

Navigate the NCSC's Cyber Assessment Framework with ASSURE-accredited consultancy

Built on extensive experience securing critical infrastructure organisations, including some of the UK largest airports, our consultants support at every stage of CAF-alignment, from scoping and assessment to remediation and continuous improvement.

Frameworks & Standards

Certification support grounded in
operational security practice

We support organisations across the frameworks that matter to their sector and supply chain, treating certification as the outcome of effective security rather than a parallel documentation exercise. Delivered by the same consultants responsible for risk, architecture, and governance advisory, our engagements ensures standards reflect how security actually operates.

ISO · Certification

ISO 27001: Information Security

Gain assurance that your information security management systems reflect how your organisation actually manages risk. Aligning to this international standard involves scoping, risk assessment, control selection, and audit preparation.

NIST · US

NIST Cyber Security Framework

Organisations must demonstrate that cyber risk is managed in line with recognised standards. Assessment against the NIST Cyber Security Framework provides a structured view of maturity and a prioritised roadmap to strengthen governance, control and resilience.

Get in touch →
NCSC · CAF · CNI

NCSC Cyber Assessment Framework

Organisations mandated under NIS and other regulations must evidence how cyber risk is managed across critical services. Our ASSURE-accredited consultants provide independent validation against NCSC expectations; from assessment and gap identification, to remediation and continuous improvement.

Data Protection SERVICES

GDPR compliance and data
governance that holds under scrutiny

Managing personal data introduces both regulatory obligation and operational risk. Our data protection services span gap analysis, data mapping, and Microsoft Purview implementation, bringing organisations clarity on how data moves, where it is exposed, and how it should be controlled in practice.

Data mapping

GDPR Data Mapping

Understanding where personal data sits and how it moves is fundamental to compliance. Data mapping establishes an accurate Record of Processing Activities (ROPA) and traces flows across systems, suppliers, and jurisdictions, providing the basis for meeting core obligations and responding to incidents or requests with confidence.

Get in touch →
Assessment

GDPR Gap Analysis

Organisations must be able to demonstrate that personal data is handled in line with UK GDPR. This assessment identifies gaps across governance, security measures, and individual rights, quantifies regulatory exposure, and sets out a prioritised plan to bring data protection practices into line with expectations.

Get in touch →
Microsoft · Implementation

Microsoft Purview Services

Microsoft Purview enables organisations to apply control over how data is classified, shared, and protected across Microsoft 365 environments. Implementation and configuration aligns information protection policies with real usage, ensuring classification, labelling, and data loss prevention controls are applied consistently and operate as intended.

Get in touch →
Data Governance

Virtual Data Protection Officer (vDPO)

Personal data must be handled in line with regulatory expectations, supported by informed decision-making that reduces risk and ensures compliance. A vDPO provides oversight of data protection governance, ensuring policies, controls and processes align with GDPR requirements and reflect how data is actually used across the organisation.

virtual leadership

Strengthen security leadership, governance and decision-making

Security programmes often stall when organisations lack senior ownership, clear governance, or specialist oversight across risk and compliance. CSA Cyber's virtual leadership roles provide access to experienced and accredited advisors who can set direction, guide decision-making and maintain momentum, without the cost or recruitment overhead of full-time personnel.

Strategy

Virtual Chief Information Security Officer (vCISO)

Security activity must align to business objectives, be supported at board level, and operate within a clear governance structure. Our vCISO roles are here to provide senior leadership that defines risk priorities, establishes governance structures, and translates security requirements into a coordinated programme of work.

Get in touch →
Operations

Virtual Information Security Manager (vISM)

Security programmes depend on consistent execution across teams and day-to-day activity, yet responsibilities are often fragmented. This is where a vISM can provide operational oversight of security controls, policies, and day-to-day activity, ensuring agreed priorities are carried through into delivery.

Get in touch →
Data governance

Virtual Data Protection Officer (vDPO)

Personal data must be handled in line with regulatory expectations, supported by informed decision-making that reduces risk and ensures compliance. A vDPO provides oversight of data protection governance, ensuring policies, controls and processes align with GDPR requirements and reflect how data is actually used across the organisation.

Security

Virtual Security Operations (vSecOps)

Continuous monitoring and response requires operational capability that is often difficult to sustain in-house. Virtual Security Operations provides 24/7 oversight of security events, ensuring threats are identified and managed consistently without the need to build a dedicated SOC.

Get in touch →
Technology

Virtual Chief Technology Officer (vCTO)

Technology decisions introduce unintended exposure when security is not considered at the design stage. A vCTO provides technical leadership across architecture, infrastructure and roadmap planning, ensuring change is implemented coherently and security considerations are embedded into key decisions that shape the organisation’s technology estate.

Get in touch →
Architecture

Cyber Security Architecture

Security architecture should reflect how your organisation actually operates, not an idealised model. This service reviews and refines control structures ensuring they are proportionate, layered, and aligned to your threat landscape, helping teams make defensible choices across identity, network segmentation, cloud integration, and zero trust.
