We are not an embedded contingent workforce. We operate as a specialist executive advisory, assurance, recovery and innovation partner — delivering defined statements of work with measurable outcomes, governed by our own framework.
We don't just advise on compliance — we operate within it. As a niche OT security consultancy, IISZON maintains rigorous internal governance standards that mirror the frameworks we help our clients achieve. Our lean operating model means zero bureaucratic overhead without compromising on quality, security, or regulatory alignment.
Every engagement we deliver is underpinned by a proven governance structure — giving Operators of Essential Services and their supply chains the confidence that our outputs are regulator-ready from day one.
Our QMS uses ISO 9001:2015 guidance principles, covering all company policies, processes and activities including Health, Safety and Environmental management — maintained as a unified system.
Our ISMS is integrated with our QMS to create a unified approach. These policies and procedures systematically govern our sensitive data, minimise risk and ensure business continuity by proactively limiting the impact of a security breach.
The NIS Directive establishes the foundational legal obligations for Operators of Essential Services across energy, water, transport, and digital infrastructure. IISZON has direct, hands-on experience supporting regulated OES organisations through NIS compliance — from initial gap assessment through to competent authority engagement and sustained regulatory reporting.
The NCSC's CAF provides the structured methodology by which UK regulators assess the cyber resilience of OES organisations. Our consultants have applied the CAF across real regulated environments — translating its 14 principles and 39 contributing outcomes into actionable, evidenced improvement programmes that withstand scrutiny from competent authorities including Ofgem and the HSE.
IEC 62443 is the internationally recognised standard for securing Industrial Automation and Control Systems (IACS). Covering security management, system design, and component requirements across the entire OT lifecycle, it provides a risk-based framework essential for critical infrastructure operators. IISZON applies IEC 62443 principles to help OES clients achieve defensible, standards-aligned OT security architectures.
The NIST Cybersecurity Framework — and its companion SP 800-82 guidance for Industrial Control Systems — provides a globally recognised structure for managing and reducing cyber risk. IISZON uses the NIST CSF's Identify, Protect, Detect, Respond, and Recover functions as a practical lens for assessing OT environments, particularly where clients operate across international supply chains or require cross-framework alignment.
NIS2 significantly expands the scope and obligations of its predecessor — introducing stricter incident reporting timelines, broader sector coverage, and direct board-level accountability for cyber risk management. For UK organisations with EU operations or supply chain exposure, NIS2 alignment is increasingly a commercial and contractual requirement. IISZON helps clients understand their NIS2 obligations and build proportionate, evidenced response programmes ahead of enforcement.
The forthcoming UK Cyber Resilience Bill represents the next evolution of the UK's regulatory posture — expected to strengthen mandatory security standards, extend obligations across supply chains, and introduce new enforcement mechanisms for critical sectors. IISZON is actively monitoring its development to ensure our clients are positioned ahead of the legislative curve, with governance frameworks already aligned to the Bill's anticipated requirements.
