Operational Resilience & Regulatory Alignment

Structured support for resilience programmes including DORA, NIS2 and business-critical service mapping, helping organisations enhance continuity, evidence defensibility and reduce operational disruption risk.

Operational resilience ensures that organisations can continue to deliver critical services despite disruption. Whether aligned to DORA, NIS2, UK regulatory expectations or internal resilience frameworks, organisations must demonstrate clarity, evidence and realistic delivery capability.

Poleis supports organisations with practical and proportionate resilience programmes that align governance, controls, testing and reporting across the full lifecycle.

Important Business Services (IBS) & dependency mapping

Understanding critical services and upstream/downstream dependencies is foundational to resilience and regulatory compliance.

Identification and definition of Important Business Services (IBS)
Mapping of people, process, technology and third-party dependencies
Assessment of tolerances, vulnerabilities and single points of failure
Alignment with regulatory and internal governance expectations

This provides a realistic and defensible view of what organisations must protect and where operational fragility may exist.

Impact tolerances & scenario design

Setting meaningful impact tolerances is a key requirement in DORA, NIS2 and wider resilience frameworks. We help ensure tolerances are linked to real business impact.

Definition of intolerable harm thresholds
Alignment of metrics to business impact and regulatory expectations
Scenario design based on realistic, high-severity events
Identification of required evidence and sources of validation

This helps organisations understand both their resilience position and their regulatory defensibility.

Scenario testing & improvement planning

Effective resilience requires testing that demonstrates realistic organisational response to disruption.

Development of proportionate scenario tests
Design of test objectives and expected outcomes
Support for test facilitation and stakeholder walkthroughs
Analysis of weaknesses and improvement actions

Testing outputs are translated into practical, prioritised improvements aligned to ownership and delivery capacity.

DORA & NIS2 alignment

We support organisations in aligning to European and UK resilience regulations, including the Digital Operational Resilience Act (DORA) and NIS2 Directive.

Gap assessment against DORA and NIS2 requirements
Third-party and ICT dependency considerations
Governance, reporting and oversight expectations
Remediation and implementation planning

The approach focuses on clarity, evidence and sustainability—not superficial compliance.

Governance & accountability

Resilience requires cross-functional ownership and consistent governance across risk, IT, operations, security and continuity functions.

Assessment of resilience governance and reporting structures
Roles and responsibilities for disruption management
Alignment across risk, security and continuity disciplines
Evidence expectations for internal and external scrutiny

This ensures organisational readiness and supports accountable, defensible delivery.
