When business leaders think about the risks that threaten their organisations, financial, operational and regulatory concerns often top the list. Yet cyber risk has emerged as one of the most pressing challenges, particularly across supply chains.
The scale of the issue is clear. Research from Hiscox shows that 67% of firms have faced an increase in cyberattacks over the past year. Among these, 40% reported that the most common form of attack was a vendor-related breach within their supply chain, claims Moody’s.
Government agencies have also been forced to act. The U.S. General Services Administration notes that the growing number of supply chain-related incidents has driven a wave of legislation and executive action. Federal agencies are now required to implement cybersecurity supply chain risk management (C-SCRM) practices. High-profile attacks underline why. The SolarWinds Orion breach allowed hackers to compromise sensitive systems through malicious software updates, affecting more than 30,000 organisations globally.
Despite the rising threat, many companies remain underprepared. One-third of executives admit their firms lack the expertise needed to manage cyber risks effectively. This gap highlights the urgency of building stronger resilience across supply chains.
Cybersecurity vulnerabilities in supply chains typically arise in three areas: supplier systems, third-party infrastructure, and procured products or services. These weak points are often hidden within complex global networks, where subcontractors and vendors make oversight difficult. Limited transparency and inconsistent security standards across geographies only compound the risks. The consequences can be severe, ranging from data theft and loss of intellectual property to service disruption and customer dissatisfaction.
Suppliers’ poor cyber defences can expose businesses in several ways. Data breaches are the most common, leaking sensitive information such as designs and contracts. System breaches, though less frequent, can be more damaging, granting attackers access to confidential company systems. Supplier-level attacks may cause short-term disruption to deliveries, with potentially damaging ripple effects.
For organisations and governments alike, the first line of defence is controlling access to internal systems. Vendors with access to sensitive data should be classed as high risk and monitored carefully. In many firms, these suppliers are managed by HR or IT rather than procurement teams, leaving gaps in oversight. Restricting information sharing is another vital measure. Businesses should review what data is truly mission-critical and ensure sensitive files are exchanged only through secure platforms.
Developing a robust C-SCRM strategy involves several key steps. Companies must identify suppliers with access to sensitive information, reduce this list to essentials, and set strict policies on what can be shared. External cyber risk assessments can provide an additional layer of insight, helping to categorise suppliers and assign appropriate safeguards.
This is where data providers such as Moody’s can support. Moody’s Supply Chain Catalyst integrates cyber risk ratings to assess suppliers’ likelihood of experiencing an incident. Armed with this intelligence, businesses can align their information-sharing policies with each supplier’s risk profile and resource needs.
Preparedness also extends beyond cyber-specific risks. Supply chain resilience means anticipating disruption of all kinds. A cyberattack compounded by a supplier’s financial weakness, for instance, can trigger significant operational problems. Traditional mitigants such as holding extra inventory remain prudent, ensuring businesses are better positioned to withstand shocks.
In an environment where supply chain vulnerabilities are being actively exploited, ignoring cyber risk is no longer an option. Strengthening resilience today could mean the difference between disruption and continuity tomorrow.
