Closing the (Risk) Loop: Citalid Unifies Cyber Risk Modeling with Portfolio Accumulation Expanding into Reinsurance Modeling

Since its founding in late 2017, Citalid has been driven by a singular vision: unlocking confidence in cyber risk modeling to empower the entire ecosystem, ensuring trust and control across every step of the value chain. What began as a mission to equip CISOs and Risk Managers with Cyber Risk Quantification (CRQ) SaaS solutions has evolved into a comprehensive cyber risk platform, supporting over 100 global clients, including 35% of France’s CAC 40 companies.

In 2024, Citalid took a significant step forward by introducing a portfolio cyber risk analysis and underwriting technology tailored for insurers and brokers. Now, in 2025, Citalid is making one of its most transformative moves yet: entering the reinsurance market with its first clients adopting its cutting-edge risk accumulation models with a dedicated platform, Citalid Portfolio. This development marks a major milestone in the cyber insurance ecosystem, ensuring that reinsurers—the backbone of macroeconomic resilience—have the advanced tools needed to maintain risk equilibrium.

Why This Matters: Addressing a Critical Gap in Cyber Reinsurance

Reinsurers play a pivotal role in stabilizing the global economy by providing the capital necessary to absorb large-scale cyber incidents. However, one of the biggest challenges in cyber reinsurance lies in the lack of accurate and actionable data. Traditional models, primarily designed in the U.S., struggle to capture the complexities of the European cyber risk landscape. Citalid is addressing this gap with an innovative, European-based approach that leverages real-world threat intelligence and risk expertise.

Citalid’s strength lies in its deep understanding of the cybersecurity landscape through its direct engagement with CISOs. Unlike existing market models that rely mainly on limited historical claims data, Citalid integrates broader risk factors, such as attacker capabilities, victim profiling, and real-time threat intelligence. This provides a new, complementary, and more precise angle to risk assessment, enabling better-informed reinsurance decisions.

The Key Innovation: Advanced Risk Propagation Modeling & Catastrophic Scenario Library

One of the most critical aspects of cyber risk accumulation is understanding how threats propagate across interconnected organizations. Citalid’s advanced propagation models go beyond measuring the initial impact of an attack. They assess the likelihood of cyber incidents spreading across business ecosystems—whether through automated network compromise, supply chain vulnerabilities, or action-based propagation.

By incorporating epidemiological modeling techniques, Citalid can simulate various catastrophic cyber scenarios and assess their likely footprints. In partnership with scientific research institution Louis Bachelier, we’ve developed a diverse set of scenario playbooks that tailor simulations to real-world threats and portfolio specifics. Each playbook integrates various attack propagation dynamics—ranging from single points of failure to fast-spreading worms and coordinated attack campaigns—ensuring realistic and actionable risk assessments.

This level of risk propagation analysis is a game-changer for reinsurers, who require a nuanced understanding of systemic cyber risks to maintain financial stability and capital allocation.

Scaling the Citalid Engine: From Policyholders to Reinsurers

Citalid’s expertise in cyber risk frequency and severity modeling—backed by a patented technology—has already proven invaluable for insurers and brokers. Now, by extending its capabilities to cover accumulation risk, Citalid is positioning itself as a next-generation cyber risk modeler. This move aligns with its long-term vision of building a virtuous cycle of global cyber resilience.

A European Model, engineered to solve a Global Challenge

For too long, cyber risk modeling has been shaped by U.S.-centric frameworks—bringing inherent biases that overlook global realities. Citalid’s expansion into reinsurance modeling marks a crucial shift towards a European-driven approach—one that remains globally relevant while also integrating regional threat landscapes, regulatory environments, and market dynamics.

By leveraging its unparalleled cyber threat intelligence and risk assessment expertise, Citalid is not only enhancing the whole cyber insurance value chain but also reinforcing the broader ecosystem’s financial resilience against cyber threats.

Looking Ahead: A New Era for Cyber Risk Management

With this bold step into reinsurance modeling, Citalid is redefining the future of cyber risk management. By bridging the gap between cybersecurity and financial risk, it is empowering reinsurers with the intelligence and tools needed to navigate an increasingly complex cyber threat landscape.

Now is the moment to embrace cyber resilience by adopting unified, consistent, and threat-informed models across the entire value chain.
