Preparing water utilities for a new era of cybersecurity requirements

Across Europe, water utilities are accelerating their digital transformation. More utilities are investing in analytics, monitoring, and data-driven operations to reduce water losses, improve efficiency, and strengthen resilience in increasingly complex networks.

At the same time, cybersecurity concerns have become impossible to ignore.

For many utilities, this has created a difficult dilemma. While digital tools are becoming essential for modern water management, there is still significant hesitation around using external cloud-based platforms. In many cases, utilities feel safer developing systems internally, believing that keeping everything “in-house” automatically means better control and stronger security.

But cybersecurity experts increasingly point to a different reality.

In practice, internally developed systems can often create greater long-term security risks than specialized external platforms designed specifically for critical infrastructure environments.

Cybersecurity is no longer just an IT issue

The reason is simple: modern cybersecurity is no longer just an IT responsibility. It has become a full-time operational discipline.

Building a secure analytics platform today requires far more than software development. It demands continuous monitoring, vulnerability management, authentication control, infrastructure hardening, incident preparedness, compliance work, and constant adaptation to an evolving threat landscape.

This level of expertise is difficult and expensive to maintain internally, especially for organizations whose primary mission is delivering reliable water services — not running cybersecurity operations.

The challenge becomes even greater as regulations tighten across Europe. Frameworks such as NIS2 place increasing demands on critical infrastructure operators to demonstrate resilience, governance, and secure system architecture.

For many utilities, maintaining this level of cybersecurity maturity internally would require significant investments in both technology and specialized personnel.

Security must be built into the architecture from the beginning

This is where purpose-built platforms can actually reduce risk rather than increase it.

At Smartvatten, cybersecurity has been built into the platform architecture from the beginning. The company’s analytics solutions are specifically designed for water utilities operating under high security and compliance requirements.

One of the most important principles behind the platform is isolation. Data transfer is designed as a one-way flow toward the Smartvatten platform, meaning external systems cannot access internal utility networks or operational control infrastructure.

This separation significantly reduces exposure and helps protect critical environments from external intrusion.

Multiple layers of protection create stronger resilience

The platform also follows a defense-in-depth approach, where multiple layers of authentication, monitoring, encryption, and access control work together to strengthen resilience.

Instead of relying on a single protective barrier, the architecture is designed to reduce risk across every layer of the system.

Smartvatten’s solutions are also aligned with international security standards and regulatory principles, including ISO 27001 certification and NIS2-related cybersecurity requirements.

The real question is who can maintain security over time

For utilities, this changes the discussion entirely.

The question is no longer whether digitalization introduces risk. The question is who is best equipped to manage that risk over time.

For many water utilities, maintaining internally developed systems at the level modern cybersecurity requires would mean building entirely new internal competencies and teams dedicated solely to security, compliance, infrastructure, and continuous system maintenance.

That investment is substantial, and for many organizations, difficult to sustain long term.

Meanwhile, the pressure to modernize operations continues to grow. Water utilities face increasing demands related to efficiency, leakage reduction, sustainability reporting, operational resilience, and aging infrastructure.

Data-driven decision-making is becoming essential to managing these challenges effectively.

Security and innovation must work together

In this environment, cybersecurity and digital innovation cannot be treated as competing priorities. They must work together.

Specialized analytics platforms designed specifically for the water sector allow utilities to access advanced insights and operational visibility while relying on security architectures built and maintained by dedicated experts.

Ultimately, the safest solution is not necessarily the one built internally. In many cases, security is strongest when it is designed, maintained, and continuously developed by organizations whose core expertise is protecting critical data and infrastructure every single day.
