In recent years, business continuity has gained prominence within organisations, largely driven by the entry into force of DORA and the strengthening of the NIS2 Directive.

Regulatory requirements have made it clear that operational resilience is no longer optional. Nevertheless, a relevant misconception persists: assuming that Business Continuity is achieved through formal plans, documented policies or occasional exercises.

True business continuity is measured when a failure occurs. It is at that moment that many organisations discover that compliance is not synonymous with preparedness.

What DORA and NIS2 actually require in terms of business continuity

The DORA Regulation establishes clear requirements regarding ICT risk management, digital resilience testing and incident response capability for entities within the financial sector. NIS2 extends this logic to multiple critical sectors, such as healthcare, energy, transport, digital infrastructures and public administration, among others.

In both cases, the focus is not merely on the existence of formal controls, but on the effective capacity to withstand incidents, maintain critical services operational, recover in a timely manner and reduce financial and reputational impact.

Within this regulatory framework, business continuity ceases to be an administrative exercise and becomes a central element of operational resilience.

Business Continuity and DORA: why application security is decisive

Organisations must continue to invest in governance, risk management, monitoring and perimeter controls. These elements are indispensable.

However, none of these pillars is sufficient if the software supporting critical processes is not treated as a central component of the security strategy.

Software evolves continuously, undergoes changes, integrates new dependencies and exposes new attack surfaces. Occasional tests or sporadic audits do not keep pace with this dynamic.

Risk is continuous. It manifests through code vulnerabilities, insecure dependencies, design flaws or configuration errors. In the current context, the majority of critical processes are supported by applications.

When an application fails, the impact may translate into service unavailability, breach of contractual obligations and regulatory non-compliance and loss of trust.

Speaking about business continuity without integrating application security therefore means building resilience on an incomplete foundation.

Recurring assessments such as threat modelling, static and dynamic code analysis, software composition analysis, penetration testing, Red Team exercises and continuous vulnerability management are essential to ensure that the critical application portfolio does not become the organisation’s weakest point.

Business continuity under DORA and NIS2 requires continuous assessment

Both DORA and NIS2 reinforce the need for recurring assessments, continuous detection and response capability, and sustained improvement of the security posture.

This principle contrasts with reactive approaches centred on isolated interventions or corrective actions only after incidents occur.

Regulatory maturity in the business continuity process requires integration between threat modelling, code analysis, vulnerability management and recurring technical testing. Without this continuity, compliance with DORA and NIS2 tends to remain formal rather than substantive.

NIS2, organisational culture and operational continuity

NIS2 introduces a decisive element: organisational accountability and the need for cultural change.

Business continuity does not depend solely on technology. It also depends on people capable of recognizing risks, interpreting alerts and executing response plans clearly.

Regular training, alignment between technical teams, risk management and executive leadership are decisive in transforming regulatory requirements into real resilience. Without such integration, continuity remains a paper exercise.

From regulatory compliance to real digital resilience

The challenge does not lie in adding another layer of compliance, but in aligning application security with the true objectives of the regulations: reducing operational risk, protecting critical digital assets, ensuring business continuity and strengthening digital resilience.

This implies viewing software as a living asset, subject to constant change, external dependencies and continuous exposure to new threats.

DORA and NIS2 have raised the level of regulatory demand and, in doing so, exposed a recurring weakness: the difficulty in translating legal requirements into effective digital risk control.

As long as application security is treated as a technical detail, this gap will persist. Strengthening resilience begins where risk is most critical today: in the code.

Between compliance and real resilience

There is a clear difference between complying with a regulation and being prepared for a critical disruption.

Compliance ensures formal alignment. Resilience ensures continuity capability.

Business Continuity is the link between these two dimensions. When properly structured, it integrates risk management, application security, recurring assessment and organisational culture. When misunderstood, it is reduced to a set of documents that merely appear robust.

Strengthening business continuity requires acknowledging that resilience does not begin in a report. It begins in the real capacity to withstand, respond and recover.
