Marsh McLennan, Zurich Publish Whitepaper on Cyber Risk

"Strengthening society’s cyber resilience is inextricably linked to the evolution of the cyber insurance market. Creating a virtuous cycle — via incentivising cyber hygiene best practices, fostering public-private collaboration and recovery mechanisms, and establishing a common framework for structured data collection/sharing — positions the market to protect businesses against their most pressing cyber risks, fulfilling its ultimate purpose," states the whitepaper Closing the Cyber Risk Protection Gap, co-authored by Marsh McLennan and Zurich Insurance Group.

As insurers embrace the rapid adoption of AI and cloud computing, they face mounting cyber threats that demand swift, accurate risk assessments. The rise of new challenges has intensified this pressure, pushing insurers to continually evolve their strategies.

The advent of AI-powered attacks has significantly altered the cyber risk landscape. We're seeing more sophisticated and targeted breaches that can evade traditional detection methods, forcing insurers to rethink their approach to underwriting and risk assessment.

Attackers can now automate and scale their operations, potentially compromising thousands of systems in a matter of hours. This speed and efficiency pose significant challenges for insurance companies trying to quantify and price cyber risk accurately.

Insurers need to invest in their own AI and machine learning capabilities to better understand and predict cyber risk patterns. It's no longer sufficient to rely on historical data alone; there needs to be proactive and anticipatory approach to future threats.

The shift towards cloud computing has also introduced new complexities for insurers. As businesses increasingly migrate their operations to the cloud, the attack surface expands, and traditional perimeter-based security measures become less effective. This transition has forced insurance companies to reassess their risk models and develop new frameworks for evaluating cloud-based vulnerabilities.

According to the report: "As technology innovations continue to drive the digitisation of the global economy, many businesses perceive an increasing sense of cyber vulnerability. For example, 87% of global decision makers in the Munich Re Cyber Risk and Insurance Survey 2024 believe their organisations are inadequately shielded against cyberattacks."

"Better risk models and knowledge-sharing partnerships will help insurers expand the scale and scope of cyber protection. However, given the potential impact of connected cyber risk and the high claims cost related to extreme cyberattacks on, for instance, critical infrastructure, there are limits to the amount of financial loss the re/insurance industry can absorb."

Catastrophic cyber incident scenarios

According to the report, "Catastrophic cyber incident scenarios can be classified into two main categories: 1) incidents considered insurable up to a certain level, and 2) incidents generally considered non-insurable, due either to a lack of insurer risk appetite or conflicts with public policy. The categorisation is based on factors such as the nature of the cyberattack, its scope, the type of damages caused, and the economic losses at stake. Mass malware and mass cloud outages are examples of cyber incidents currently deemed insurable up to a certain financial threshold."

Cloud adoption has significantly reshaped how insurers assess cyber risk. Today, insurers must evaluate complex factors like multi-cloud environments, shared responsibility models, and API security when determining a client's risk profile. This has made the process far more nuanced and intricate than it was just a few years ago.

One of the most pressing challenges is the difficulty in accurately pricing cyber insurance policies. The fast-evolving nature of cyber threats, along with the potential for large-scale systemic attacks, complicates the establishment of sound actuarial premiums.

Cyber insurance operates under unique conditions. Unlike traditional insurance lines that rely on decades of historical data, the cyber landscape is in constant flux. Insurers are now tasked with developing new models to accommodate this ongoing uncertainty and change.

To address these challenges, many insurers are turning to advanced analytics and real-time monitoring tools. These technologies enable continuous assessment of clients' security postures, allowing for dynamic adjustments to coverage and premiums.

The shift toward data-driven underwriting is becoming more prominent, with insurers increasingly relying on real-time security scores and continuous monitoring to make informed decisions about risk and pricing. However, implementing these technologies comes with its own hurdles. Insurers must navigate regulatory complexities, ensure client data privacy and security, and maintain transparency in their underwriting processes.

As AI and machine learning play a growing role in underwriting, insurers must guard against potential biases and ensure fairness and transparency in their models. The explainability of these models is also critical, as decisions need to be justified to both regulators and clients.

Despite these challenges, the insurance industry remains optimistic about its ability to adapt to the evolving cyber risk landscape. Companies are investing heavily in research and development, partnering with cybersecurity firms, and collaborating with academic institutions to stay ahead of emerging threats.

The industry is also exploring innovative products like parametric insurance policies, which provide rapid payouts based on predefined triggers, and more granular coverage options that allow businesses to customise policies to their specific risk profiles.

As the cyber insurance market matures, experts predict greater standardisation in policy wording, improved data sharing among insurers, and more advanced risk transfer mechanisms.

Although the cyber insurance market is still in its infancy compared to other insurance lines, we are witnessing rapid innovation and progress. As our understanding of cyber risk deepens and more sophisticated assessment tools emerge, insurers are poised to offer more comprehensive and effective coverage. The key to success will be maintaining agility and fostering collaboration across the industry.

Key Statistics

• Cyber Risk as a Top Concern: According to the World Economic Forum’s Global Risks Report 2024, 40% of experts surveyed consider cyberattacks a paramount risk with the potential to trigger a material crisis, ranking cyberattacks among the top five global risks.

• Global Cybercrime Costs: The global cost of cybercrime is projected to rise from USD$8.5trn in 2022 to nearly USD$24trn by 2027.

• Ransomware Growth: Ransomware payments reached a record-breaking USD$1.1bn in 2023.

• Cyber Insurance Market Growth: The global cyber insurance market is valued at USD$14bn gross written premium (GWP) in 2023 and is projected to more than double to USD$29bn by 2027.

• Despite this growth, the cyber risk protection gap is substantial. Insured losses cover only 1% of economic losses due to cyberattacks, leaving a USD$0.9trn protection gap.

• Regional Cyber Insurance Projections:

  • North America:
    2023 - USD$10.1bn
    2027 - USD$19.7bn

  • Europe:
    2023 -  USD$2.8bn
    2027 - USD$6.6bn

  • Asia/Oceania:
    2023 - USD$0.9bn
    2027 - USD$2.0bn

• Cyber Vulnerability Among Businesses: 87% of global decision-makers believe their organisations are inadequately shielded against cyberattacks.

• Challenges for Small- and Medium-Sized Businesses (SMBs): Many SMBs remain uninsured or underinsured due to affordability, lack of risk awareness, or understanding of coverage.
