Force Majeure

What is force majeure in the context of cybersecurity?

Force majeure, a French term meaning "superior force," is a contractual clause that frees both parties from liability or obligation when an extraordinary event or circumstance beyond their control prevents one or both from fulfilling their obligations. Traditionally associated with natural disasters, wars, epidemics, and civil unrest, force majeure has taken on heightened significance in the digital era.

In the realm of cybersecurity, force majeure addresses risks tied to digital infrastructure, data protection, and service delivery. It typically covers events that are unforeseeable, unavoidable, and outside the reasonable control of the affected party. Examples include:

• A state-sponsored cyber warfare attack leading to widespread infrastructure collapse
• A massive, unpreventable ransomware campaign that overwhelms global defenses
• A natural catastrophe destroying data centers and disrupting cloud services

The specific wording of a force majeure clause in cybersecurity agreements—such as SaaS contracts, cloud service agreements, or managed security service agreements—dictates which cyber-related events qualify and what remedies or suspensions of service are permitted.

Why is a force majeure clause essential in cybersecurity contracts?

Force majeure clauses are critical in cybersecurity contracts because they directly impact business continuity, service level agreements (SLAs), and legal liabilities during extreme disruptions. Without a well-drafted clause, organizations may face costly disputes over responsibility when catastrophic cyber events occur.

Key reasons these clauses are essential include:

• Risk allocation: They clearly define which party bears the risk during extraordinary events, reducing ambiguity and potential litigation.
• SLA protection: Service providers can be excused from SLA penalties when events genuinely fall outside their control, as recognized by frameworks from organizations like ISACA and NIST.
• Business continuity planning: A well-structured clause encourages both parties to develop robust continuity and disaster recovery plans.
• Regulatory compliance: Regulations such as GDPR and CCPA may influence how force majeure interacts with data protection obligations, making precise contractual language vital.

How do you invoke a force majeure clause in a cybersecurity incident?

Invoking a force majeure clause during a cybersecurity incident requires a structured and well-documented approach. Organizations should follow these steps:

1. Review the clause language: Carefully examine the contract to determine whether the specific cyber event falls within the enumerated force majeure triggers. Generic language like "acts beyond reasonable control" may apply differently than explicitly listed events such as "cyber warfare" or "critical infrastructure failure."
2. Document the event: Collect thorough evidence demonstrating the nature, scale, and impact of the incident. This includes incident response logs, threat intelligence reports, and third-party assessments.
3. Demonstrate causation: Prove that the event directly prevented or materially impaired the party's ability to fulfill contractual obligations, and that no reasonable alternative existed.
4. Provide timely notice: Most contracts require prompt written notification to the other party. Failure to provide timely notice can void the right to invoke the clause.
5. Mitigate damages: Show that reasonable steps were taken to minimize the impact of the event, such as activating disaster recovery plans or engaging incident response teams.

Organizations are advised to consult legal counsel and reference guidance from agencies like CISA to support their position.

When does a cybersecurity incident qualify as force majeure?

Not every cybersecurity incident rises to the level of force majeure. For a cyber event to qualify, it generally must meet three criteria:

• Unforeseeability: The event was not reasonably anticipated at the time the contract was executed. A novel, unprecedented zero-day exploit or a previously unknown attack vector may qualify, while well-known threat types typically do not.
• Unavoidability: Despite implementing industry-standard security measures and best practices (aligned with frameworks such as ISO 27001 or NIST Cybersecurity Framework), the event could not have been prevented.
• External causation: The event originated from outside the affected party's sphere of control—for example, a state-sponsored attack on national infrastructure or a global ransomware pandemic.

Real-world examples:

• A state-sponsored cyberattack targeting critical national infrastructure leads to a widespread power grid failure, impacting data centers and rendering cloud services unavailable for an extended period.
• A novel and unprecedented zero-day ransomware worm rapidly propagates globally, overwhelming traditional defenses and causing massive, unrecoverable data loss for numerous organizations simultaneously.

Which types of cyber incidents are typically excluded from force majeure?

Many cybersecurity incidents do not qualify as force majeure because they are considered foreseeable or preventable risks that organizations are expected to manage through standard security practices. Commonly excluded incidents include:

• Phishing attacks and social engineering: These are well-documented threats that can be mitigated through employee training and technical controls.
• Known vulnerability exploits: If a breach results from failure to patch a known vulnerability, the affected party is unlikely to claim force majeure, as the risk was foreseeable and avoidable.
• DDoS attacks: While disruptive, DDoS attacks are a common and anticipated threat, and mitigation services are widely available.
• Insider threats: Malicious or negligent actions by employees or contractors are generally considered within the organization's control.
• Routine malware infections: Standard malware that can be addressed by conventional antivirus and endpoint protection measures is not extraordinary enough to qualify.

The distinction ultimately hinges on the specific contract language, the scale and novelty of the incident, and whether the affected party exercised reasonable due diligence. Courts and arbitrators often scrutinize whether the invoking party met accepted cybersecurity standards before granting force majeure relief. Organizations should work closely with legal and cybersecurity professionals to ensure their contracts reflect the evolving threat landscape and clearly delineate the boundaries of force majeure applicability.
