Supply Chain Risk in 2026
The Hidden Threat Beyond Your Estate
In this Blog
Organisations are connected to more than ever before meaning supply chains have expanded and so too has the level of risk associated with these diverse supply chains. Cloud services, managed service providers, SaaS platforms, open source software and outsourced business functions now form part of an extended digital supply chain that sits well beyond the traditional network perimeter. According to recent industry analysis by DeepStrike, third party involvement is now present in approximately 30% of all data breaches, double the proportion seen just a few years ago.
More concerning still, research from IBM shows that breaches involving supply chain compromise are typically more expensive and take longer to contain than other incidents. While the global average cost of a data breach currently sits at roughly $4.44 million, breaches via supply chains are uniquely more damaging. A supply chain compromise is one of the most significant factors that amplifies the total cost of a breach. In the UK it can cost an organisation an additional average of £241,620.

According To IBM’s Cost of a Data Breach Report 2025 it takes an average of 267 days to identify and contain a breach. As attackers increasingly exploit trusted relationships, instead of relying solely on technical vulnerabilities, supply-chain risk is now one of the most critical cyber security challenges for organisations of any size.
Understanding Your Supply Chain Risk
Supply chain cyber risk refers to the exposure an organisation faces as a result of its reliance on third‑party suppliers, vendors, partners, and software components. Rather than attacking a target directly, threat actors compromise a supplier and leverage the trust relationship to gain access to downstream victims.
Supply chain attacks have become an increasingly common and damaging tactic among cyber criminals. These breaches highlight just how vulnerable organisations can be when the security of their partners, vendors, and software providers is compromised.
Understanding supply chain risk begins with achieving full visibility across all third-party services and suppliers your organisation relies upon. Identifying these critical relationships is essential, as gaps in awareness can expose internal systems and sensitive data to external threats.
Assessing each supplier’s security maturity and posture helps clarify potential vulnerabilities, while evaluating how easily attackers might exploit these connections provides insight into your overall risk profile.
Importantly, your industry or sector also shapes the likelihood and nature of supply chain attacks. Certain fields, such as finance or healthcare, face heightened targeting due to the value of their assets and data. Proactive supply chain risk assessment empowers organisations to anticipate, mitigate, and respond to threats more effectively.

Why Supply Chain Risk Management Matters
Supply chain attacks are no longer rare, isolated incidents. Industry reporting throughout 2024 and 2025 shows sustained growth in both the frequency and impact of supply‑chain driven breaches, particularly those involving software vendors, open‑source ecosystems and managed service providers. This surge has prompted organisations to turn to established frameworks and risk models for guidance in managing supply chain cyber risk.
NIST Framework
One of the most widely recognised frameworks is the NIST Cybersecurity Framework (CSF), which provides a structured approach to identifying, protecting, detecting, responding to, and recovering from cyber threats, including those originating from the supply chain.
NIST has published dedicated guidance, such as NIST SP 800-161 Revision 1: “Cybersecurity Supply Chain Risk Management Practices for Systems and Organizations”, which outlines best practices for assessing, monitoring, and mitigating risks associated with third-party vendors, software components, and service providers. The framework emphasizes the importance of integrating supply chain risk management (SCRM) into overall cybersecurity strategy, including activities like supplier risk assessments, contract security requirements, continuous monitoring, and incident response planning.
Other Frameworks
Other notable frameworks include the ISO/IEC 27001 and ISO/IEC 27036 series, which address information security management and specific guidelines for managing risks in supplier relationships. The Center for Internet Security (CIS) Controls also recommends measures such as maintaining an inventory of third-party assets, enforcing least-privilege access, and regularly validating supplier security practices.
By leveraging these frameworks, organisations can systematically identify vulnerabilities in their supply chain, implement robust controls, and foster a culture of continuous improvement and vigilance. Proactive supply chain risk management is now considered essential for defending against the evolving threat landscape, as highlighted by recent high-profile breaches and ongoing industry research.
Real‑World Supply Chain Breach Examples
XZ Utils Open‑Source Backdoor (2024): A sophisticated backdoor was discovered in a widely used Linux compression library, demonstrating how long‑term social engineering and open‑source dependency risks can threaten critical infrastructure globally. (source: Datadog Security Labs)
SolarWinds Orion Breach (2020): Perhaps the most infamous supply chain attack in recent memory, the SolarWinds incident saw hackers infiltrate the company’s software development pipeline. By compromising updates for the widely used Orion IT monitoring platform, attackers were able to insert malicious code that was subsequently pushed to approximately 18,000 customers, including major government agencies and global corporations. This breach demonstrated how a single compromised supplier can result in a cascade of downstream victims, often undetected for months. (source: NCSC)
Kaseya Ransomware Attack (2021): In another headline-grabbing example, cybercriminals targeted Kaseya, a company that provides IT management software to managed service providers (MSPs). By exploiting a vulnerability in Kaseya’s VSA platform, hackers were able to distribute ransomware to hundreds of organisations in one coordinated attack. The event underscored how attackers can use trusted software suppliers as a force multiplier to scale their impact and bypass traditional security measures. (source: PurpleSec)
Jaguar Land Rover Supply Chain Attack (2024): In a high-profile incident, attackers targeted Jaguar Land Rover by exploiting a well-known vulnerability in a third-party SAP (NetWeaver) platform used by one of the automaker’s suppliers. This breach disrupted production and supply chain operations, demonstrating how cybercriminals can leverage weaknesses in widely deployed enterprise software to compromise even mature organisations. The overall cost from the incident is estimated to be at least £1.9 billion ($2.5 billion), making it the most economically damaging cyber event ever recorded in the UK. The attack halted production at multiple sites, affected over 5,000 organisations in the supply chain, and required a £1.5 billion government loan guarantee to stabilise operations. JLR’s wholesale deliveries dropped nearly 25% year-on-year, and recovery is still ongoing in early 2026. (source: SysGroup)
These real-world cases serve as stark reminders that even the most robust internal cybersecurity practices can be undermined if third-party partners and software providers are not held to the same standards. Vigilance, continuous oversight, and a strong supply chain risk management strategy are essential to safeguarding today’s interconnected digital infrastructure.
5 Steps to Reducing Supply Chain Risk
Organisations can significantly reduce their exposure through visibility of suppliers, proportionate due diligence, least‑privilege access, continuous monitoring and robust incident response planning.
- Supplier Visibility: Maintain an up-to-date inventory of all suppliers, vendors, and third-party service providers. Use standardised risk classification, as outlined by NIST CSF and ISO/IEC 27036, to segment suppliers based on the sensitivity and criticality of their access and services.
- Proportionate Due Diligence: Conduct thorough risk assessments before onboarding new suppliers, scaling the depth according to their potential impact. Review security certifications, controls, and incident history to align with NIST SP 800-161 and ISO/IEC 27001 requirements for evaluation and ongoing monitoring.
- Least-Privilege Access: Enforce strict access controls so suppliers only have the minimum necessary access to perform their duties. Both NIST CSF and CIS Controls support the least-privilege principle to limit potential damage from breaches.
- Continuous Monitoring: Implement real-time monitoring of supplier activities and automated alerts for unusual behavior. Regularly validate supplier security practices through audits, questionnaires, or penetration testing as recommended in NIST and ISO frameworks.
- Robust Incident Response Planning: Integrate suppliers into your incident response plans by establishing clear communication channels, escalation paths, and joint response exercises. NIST CSF emphasizes the importance of coordinated response and recovery processes that include third-party partners.
By aligning your supply chain risk management with established models like the NIST CSF and ISO/IEC standards, you can effectively identify vulnerabilities, implement targeted controls, and foster a culture of continuous improvement—significantly reducing the likelihood and impact of supply chain cyber incidents.
