What is cyber resilience?

Cyber resilience brings together business continuity, information systems security and organizational resilience. It describes the ability to continue delivering intended outcomes despite experiencing disruptive cyber events, such as cyberattacks, natural disasters or economic slumps. How well an organization manages information security affects how much downtime it faces during a disruption.

Today’s cyberthreats present new challenges, creating an environment where traditional security measures alone are insufficient. Organizations face sophisticated adversaries who use advanced technologies and techniques to cause disruptions. According to the Cyberthreat Defence Report 2026 from CyberEdge Group, 81% experienced at least one successful cyberattack in the past year.

Rather than relying on automated, brute force attacks, hackers increasingly turn to ransomware and phishing-driven stolen credentials, exploiting human vulnerabilities and system weaknesses instead.

The 2026 Cost of a Data Breach Report from IBM and the Ponemon Institute found that the global average cost of a data breach climbed to USD 4.99 million, a 12% increase over the prior year and a record high. Artificial intelligence (AI) contributes to that increase: the report also found a 56% increase in AI-powered attacks, led by AI deepfake impersonations and AI-enabled malware. 

Cyberattacks are not just an IT problem; they’re an infrastructure challenge with direct operational, financial and regulatory compliance consequences. Regulations are shifting the requirements from preventing attacks to proving an organization can recover from them. For example, regulations like the European Union (EU)’s Digital Operations Resilience Act (DORA) require financial entities to test their recovery processes and document proof they can restore them. Organizations are making cyber resilience, along with wider operational resilience, a board-level priority rather than a technical one.

Enterprises must build effective cyber resilience through a risk-based strategy and coordinate initiatives to support it. This requires an executive-led, collaborative approach that extends across the organizational ecosystem to include partners, supply chain participants and customers. It must proactively manage risks, threats, vulnerabilities and the effects on critical information and supporting assets, while also strengthening overall preparedness.

Successful cyber resilience also involves data governance cyber risk management, incident management and an understanding of data sovereignty. Aligning these disciplines within an effective cyber resilience strategy is not something an organization can improvise on the fly. It is the product of experience, sound judgment, and crucially, a defined set of principles that guides a comprehensive plan.

Though often used interchangeably, cyber resilience and cybersecurity are not the same, but different domains that work together.

Cybersecurity focuses on protecting an organization’s infrastructure, applications and data from attack. It is a foundational part of cyber resiliency, which is the overarching strategy that focuses on what happens at the point of the attack. Cyber resiliency ensures that a business can maintain operations, protect data and successfully recover after an incident such as a breach or ransomware attack.

In short, strong cybersecurity reduces how often attacks happen and how much damage they do, and cyber resilience keeps an organization running even when an attack gets through.

A cyber resilience strategy helps organizations:

- Mitigate financial loss
- Gain customer trust
- Remain compliant
- Increase competitive advantage
- Ensure business continuity

Financial loss from successful attacks might lead to a loss of confidence from company stakeholders, such as shareholders and other investors, employees and customers. The IBM 2026 Cost of a Data Breach Report revealed that organizations with extensive AI use in security operations saved an average of USD 1.93 million in breach costs compared to organizations that don’t use any AI.

However, organizations experiencing AI-related incidents without proper access controls faced higher costs, highlighting the need for effectively governed cyber resilience strategies.

Cyber incidents can severely impact an organization's reputation and customer confidence. A robust cyber resilience framework helps organizations respond quickly and transparently to incidents, minimizing long-term reputational harm and maintaining stakeholder trust.

To help gain the trust of customers and win their business, some organizations comply with international management standards, such as ISO/IEC 27001 provided by the International Organization for Standardization. ISO/IEC 27001 provides conditions for an information security management system (ISMS) to manage asset security like employee details, financial information, intellectual property or third-party entrusted information.

In the US, companies might seek certification with the Payment Card Industry Data Security Standard (PCI-DSS), a prerequisite for processing payments.

Enterprises that develop structured approaches, such as threat intelligence programs, along with standardized best practices for addressing incidents, can create more effective operations and deliver greater value to their customers. This readiness creates sustainable business advantages over less-prepared competitors.

Organizations with a robust cyber resilience plan can maintain critical operations during a wide range of incidents, minimizing downtime and ensuring continuous service delivery to customers. The 2026 Hidden Costs of Downtime Report from Splunk 2026 found that the average organization now loses more than USD 900,000 per hour to downtime.

Numerous government agencies, standards bodies and industry groups have published frameworks that provide elements for building cyber resilience. One widely known framework comes from the National Institute of Standards and Technology (NIST). The NIST Cyber Security Framework (NIST CSF) rests on six functions, also frequently referred to as pillars:

1.    Govern: Establish cybersecurity governance and risk mitigation policies that inform and prioritize cybersecurity activities, enabling risk-informed decision-making across the enterprise.

2.    Identify: Develop a comprehensive understanding of the most critical assets and resources along with their relationships and dependencies. This function encompasses asset management, business environment evaluation, governance frameworks, risk assessment and supply chain risk management. 

3.    Protect: Implement appropriate technical and physical security controls to protect critical infrastructure. Key areas include security awareness and training, data security and data protection processes, and security maintenance.

4.    Detect: Deploy systems that provide alerts about cybersecurity events and evolving threats. This includes continuous monitoring and anomaly identification, along with regular testing to ensure detection systems can catch real threats.

5.    Respond: Ensure appropriate response capabilities for cyberattacks and other cybersecurity events. This strategy includes response planning, stakeholder communication strategies, incident analysis and threat mitigation.

6.    Recover: Implement recovery strategies for cyber resilience to ensure business continuity following cyberattacks, security breaches or other cybersecurity events. This step involves developing and implementing plans and procedures to recover systems, data and services, as well as a framework for improving future responses.

Sustaining cyber resilience requires continuous adaptation, strategic investment and the integration of emerging technologies while maintaining core security principles.

To create a solid strategy, organizations often follow an established cyber resilience framework, such as the NIST CSF. In many cases, organizations also draw on elements of established cybersecurity frameworks, such as the CIS Critical Security Controls (CIS Controls) or supplement their own models with information from adjacent frameworks like the Information Technology Infrastructure Library (ITIL. 

An effective cyber resilience strategy includes:

1.    Risk assessment: Identify and prioritize the assets, systems and data most critical to the business, along with the threats and vulnerabilities that put them at risk.

2.    Executive sponsorship: Secure leadership backing so resilience initiatives get the budget, staffing and cross-functional cooperation they need.

3.    Layered defenses: Combine preventive, detective and corrective controls for cost-effective, rapid detection and correction, so no single point of failure can take down the organization.

4.    Incident response planning: Document clear roles, escalation paths and communication plans before an incident happens, not during one.

5.    Security awareness training: Implement employee training. Security and other IT teams need to recognize phishing attempts and other social engineering tactics, since attackers increasingly exploit human error rather than technical vulnerabilities.

6.    Regular testing: Run tabletop exercises, penetration testing and recovery drills on a set schedule to verify that plans work under real conditions, not just on paper.

7.    Continuous improvement: Input lessons from every test and every real incident back into the strategy, and update it as threats evolve.

The following tools help organizations withstand and recover from cyberattacks while minimizing disruption to business operations:

- Security orchestration, automation and response (SOAR): SOAR software solutions enable security teams to integrate and coordinate separate security tools, automate repetitive tasks and streamline incident and threat response workflows.

- Security information and event management (SIEM): SIEM systems provide centralized logging capabilities and conduct real-time analysis of security events across the organization’s entire infrastructure.

- Identity and access management (IAM): IAM solutions offer comprehensive user authentication and access controls that help ensure only authorized personnel can access critical systems and data.

- Zero-trust architecture: A zero-trust security model operates on the principle of assuming no implicit trust, and it continuously validates access requests, regardless of user location or device.

- Cloud security platforms: These specialized tools provide protection designed explicity for cloud-based assets and workloads across hybrid and multicloud environments. 

- Disaster recovery (DR) solutions: These systems provide automated backup and restore and disaster recovery capabilities for critical data and applications, helping ensure rapid restoration of operations following security incidents.

- Continuous monitoring platforms: These solutions provide real-time visibility into security posture and threat landscape, enabling proactive threat management and risk assessment.

- Cyberattack simulation tools: These tools simulate realistic attack scenarios across an organization’s attack surface to assess organizational preparedness, train teams and identify gaps in incident response plans.

Several trends are influencing how organizations approach cyber resilience:

- AI governance
- Extended detection and response (XDR)
- Supply chain security
- Quantum computing
