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.
