Cyber resilience that genuinely moves organizations and people forward

At Eraneos, we don’t see cybersecurity as a necessary evil or a technical checkbox; we see it as a strategic opportunity. We work for clients across a wide range of sectors: from financial services providers and insurers to industrial companies, energy and utility firms, government agencies, and public service organizations in the social sector, often organizations that play a critical role in society.

Our approach is purpose-driven. We start with the business: with the client’s objectives, risks, and unique context. From that understanding, we design tailored solutions that connect strategy, execution, and innovation. And we don’t stop at advice: we stay involved until it works in practice, from the initial analysis through implementation to the people who work with it every day. No theoretical frameworks gathering dust, but cyber resilience that holds up, especially when the pressure is on. 

Stronger together against cyber threats

In our Cybersecurity team, we thrive on complex challenges at the intersection of technology, risk, and business. One moment we’re sitting down with the CISO to talk governance, the next we’re thinking through design choices with architects or diving deep with a security team on SOC optimization or a red team exercise. We take on that variety together: we spar with each other, share what we encounter at clients, and complement one another, one colleague going deep on the technology while another keeps an eye on the bigger picture. We take ownership, follow through, and know how to communicate our insights clearly at every level. That’s how we grow together, in both depth of expertise and impact, delivering work with visible results for clients who truly rely on us.

We’re curious and driven by technological progress. We enjoy sharing knowledge, we like working together toward results, and at the same time we have the confidence to set direction independently. And we keep learning: about evolving threats, about developing regulations, and about technologies like AI that continually redefine the playing field.

What makes us unique? Here, you combine strategic vision with advanced technology and practical, hands-on expertise. So, you’re not building an isolated layer of security around the organization, you’re helping to embed cyber resilience at its core, from the boardroom to the codebase. 

The four pillars of cyber resilience

We work across four areas of expertise, each with its own focus but constantly intertwined in practice. Together they form an end-to-end approach that helps our clients turn cybersecurity into a strategic advantage with measurable impact.

Cyber Strategy & Governance

“Where are we headed?” Success starts with clarity. We help leadership teams align cybersecurity with business goals, regulatory requirements, and a shifting risk landscape, using strategic frameworks that fit the organization and grow with its ambitions. At the same time, we build resilience through readiness assessments, exercises, response planning, and post-incident evaluations, so organizations are prepared before things go wrong. With ISMS implementations, we anchor this approach in the organization’s processes as well.

Digital Risk & Compliance

“What’s at stake?” Effective protection starts with a clear view of the client’s risk landscape and regulatory obligations. We distill complex issues into clear insights and concrete actions, with an approach tailored to the client’s goals, industry, and regulatory environment. From Cyber Risk Management (using frameworks such as ISO 27005, NIST, and FAIR) and Cyber Regulatory Compliance (including NIS2, DORA, and the EU AI Act) to data privacy under the GDPR — this is how we help our clients build trust, reduce risk, and avoid costly fines.

Secure Innovation & Design

“How do we build it so it keeps working?” The most effective cybersecurity is built into digital products and systems from the start. Together with architecture, development, and operations teams, we embed security principles at every stage, making systems more resilient to threats while helping innovation move faster and more safely. Our focus areas range from Identity & Access Management and Application Security (with automated testing and secure coding standards in the CI/CD pipeline) to IT Infrastructure Security, AI Security (protecting AI/ML models and using AI for threat detection), and OT Security, where we bridge the gap between IT and industrial environments.

Offensive & Defensive Security

“Are we ready, and will we come out stronger?” This is where strategy becomes reality. We provide the hands-on support that closes the gap between strategic plans and actual protection, combining technical depth with a real understanding of the client’s organization. On the offensive side, we expose vulnerabilities through ethical hacking, penetration testing, and red team exercises, keeping organizations one step ahead of attackers. On the defensive side, we optimize architecture, tooling, and the performance of Security Operations Centers (SOCs), turning existing defense strategies into an advanced, measurable response to threats. The human side matters too: through awareness and training programs (Human Risk Management & Secure Behavior), we turn people into a strong link in the defense.

Results with lasting impact

Professionalizing the SOC of a European insurer

Professionalizing the SOC of a European insurer

A European insurer and asset manager wanted to strengthen its Security Operations Center (SOC): meeting stricter regulations, improving collaboration, and handling systemic incidents more efficiently. We explored the sourcing scenarios, from keeping the current setup and outsourcing 24/7 support to bringing all monitoring fully in-house, and laid out the pros and cons of each in clear detail.

Implementing Zero Trust for critical Dutch infrastructure

Implementing Zero Trust for critical Dutch infrastructure

Critical infrastructure is a prime target for cyberattacks worldwide. That’s why our client wanted to better protect both its supply chain and its IT environment. Perimeter security no longer cuts it, so the ambition was Zero Trust: continuously verifying every access point and every communication. At the same time, essential organizations have to scale up significantly with NIS2 on the horizon. Eraneos was glad to take on this “never trust, always verify” challenge.

A practical simulation for a large government organization

A practical simulation for a large government organization

A large government organization was undertaking a change initiative within its IT department. The existing way of working no longer matched the growing complexity of projects and the pressure to deliver faster and in a more integrated way. New roles and fixed points of contact were therefore defined, with the aim of streamlining collaboration and speeding up decision-making.
