Secure AI systems and defend against AI-enabled threats
AI introduces risk through both adoption and misuse; from uncontrolled 'shadow AI' use by employees to vulnerabilities in the systems you build and deploy.
Our AI security services help organisations regain and reinforce control, combining risk assessment, adversarial testing and governance design to manage how AI is used, secured and trusted across the business.

ISO 42001: AI Intelligence
For organisations developing, deploying, or procuring AI systems, ISO/IEC 42001 provides a recognised standard for establishing governance that can be evidenced to customers, regulators, and partners.
Adversarial testing of AI systems and large language model (LLM) deployments, aligned to the OWASP LLM Top 10. Focus areas include prompt injection, data leakage pathways, model manipulation, and guardrail bypass, with reporting written to support practical remediation by engineering teams.
This assessment establishes a structured understanding of AI-related exposure, identifying risks across data, models and usage, and producing a prioritised risk register and roadmap aligned to your existing governance framework or ISO 42001 objectives.
AI introduces new behaviours across the workforce; from how information is shared to how decisions are supported and automated. This training equips staff to use AI tools responsibly in practice, reducing the risk of data exposure, misuse and AI-assisted attacks while aligning day-to-day behaviour with your organisation’s policies.
Ensure AI systems are governed in line with organisational risk, regulatory expectations and standards such as ISO 42001. AI governance defines the policies, controls and oversight needed to manage data, model behaviour and decision-making, enabling AI to be adopted confidently and managed in practice.
Security for the systems that control physical processes and critical infrastructure
Operational technology environments introduce risk where cyber incidents directly impact safety, production and operational continuity. Traditional IT security approaches are frequently incompatible with these environments, where intrusive testing or control changes can cause disruption.
Our OT security services are delivered using passive-first and production-aware methodologies, ensuring risks are identified and managed without affecting live operations.

IEC 62443: Operational Technology
Operational technology environments require controls that protect availability and safety without disrupting critical services. IEC 62443 assessments identify risks across OT architectures and strengthen segmentation, control effectiveness and resilience in complex, industrial environments.
Operational environments cannot tolerate the disruption caused by traditional Penetration Testing approaches. This service safely tests ICS, SCADA and PLC environments using passive-first methodologies to identify exploitable paths, vulnerable access points and insecure system interactions, exposing risk without disrupting live operations or impacting safety-critical processes.
Continuous visibility is essential in OT environments where traditional monitoring approaches can introduce risk. Delivered through our in-house, UK-based SOC, this service provides passive monitoring of network activity, identifying anomalous behaviour and potential threats while preserving the integrity and availability of critical processes.
Gain clarity on cyber risk across transactions and business-critical changes
Mergers, acquisitions and strategic investments expose organisations to inherited cyber risk that is often not visible until after the deal is complete. Effective cyber due diligence provides a clear understanding of security posture, control maturity and potential liabilities before decisions are finalised. Our services support deal teams with independent, evidence-based assessment of risk, enabling informed transaction decisions, accurate valuation and structured remediation planning.
Assessment
Cyber Due Diligence Assessment
Acquiring an organisation means inheriting its cyber risk, including vulnerabilities, legacy systems and historic incidents that may not be immediately visible. This service provides a structured assessment of security posture, identifying control gaps, exposure and material risks to support informed deal decisions and risk-aware negotiation.
Suppliers and partners often introduce risk that sits outside traditional security controls. This service establishes a structured, proportionate approach to third‑party cyber risk, supporting procurement, risk owners, and governance teams with clear tiering, assessment criteria, and reporting that stands up to scrutiny.
Security gaps identified during due diligence require structured planning to address without disrupting business operations. This service defines remediation priorities and integration strategy, aligning security controls, governance and systems to support a secure and controlled transition following acquisition.
Minimise human risk by enforcing awareness at a culture level
Security training is only effective if it changes how people behave in practice. Generic content and completion-based programmes rarely translate into reduced risk. Our training and education services are built around your organisation’s actual threat landscape, policies and user behaviours; combining structured programmes, realistic simulation and targeted learning to reduce human risk in measurable ways.
In-person · Computer-based
Cyber Security Awareness Programme
Security awareness programmes often fail when they are disconnected from real-world threats and user behaviour. This programme is built around your organisation’s risk profile, policies and culture, delivering structured, ongoing training that reinforces safe behaviour, improves incident reporting and drives measurable reduction in human risk over time.
Phishing remains one of the most reliable entry points for attackers, particularly when simulations do not reflect real threats. This service combines tailored phishing simulation with immediate targeted training, using realistic scenarios to test user behaviour, reinforce learning and demonstrate measurable improvement across roles, departments and seniority levels.
Senior leadership are accountable for cyber risk but often lack visibility into how it should be governed and challenged. These briefings provide a structured understanding of relevant threats, governance responsibilities and key decision points, enabling boards and executives to oversee cyber risk with confidence.
Incident response plans are often untested until they are needed most, leaving teams unprepared for the realities of a live incident. These exercises simulate realistic cyber scenarios, enabling leadership and technical teams to test decision-making, roles and communication under pressure, and identify gaps in processes before a real event occurs.
AI introduces new behaviours across the workforce; from how information is shared to how decisions are supported and automated. This training equips staff to use AI tools responsibly in practice, reducing the risk of data exposure, misuse and AI-assisted attacks while aligning day-to-day behaviour with your organisation’s policies.
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.
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.
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.
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.
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.
Effective security architecture requires continuous alignment with evolving business requirements and risk exposure. A Virtual Security Architect provides ongoing oversight, shaping design decisions and ensuring controls are applied consistently across programmes and environments.
