Businesses are deeply interconnected – and cyber risks in one part of the supply chain can have far-reaching effects, according to a vendor. Incidents can affect the global supply chain, as seen in the Kaspersky (June 2024), Snowflake (May 2024), and Crowdstrike (July 2024) incidents, says Bitsight in its report, Under the Surface: Cybersecurity Risks within the Global Supply Chain.
Bitsight’s global and UK-specific data is based on an analysis of 500,000 organisations, 40,000 products, and 12,000 providers, mapping over 61 million digital supply chain relationships. Among the findings – the typical UK organisation uses 29.1 providers and 81.6 products; that’s a larger supply chain by a tenth than the global average. As the cyber firm points out, the larger and more complex a supply chain, the greater the attack surface, increasing opportunities for cybercriminals to infiltrate networks. The report makes the point that supply chain risks donโt just come from direct providers โ they extend through multiple tiers, creating hidden vulnerabilities that businesses may not be aware of.
UK reliance
According to the study, 30 per cent of the UK supply chain relies on organisations designated by the United States’ Department of Defense as โChinese Military Companies.โ Bitsight says that the continued reliance on these providers underscores the challenge of securing the digital supply chain against foreign influence. Even with increased scrutiny and regulatory efforts, Chinese state-linked firms maintain a significant foothold in UK industries, making it critical for organisations to assess their vendor relationships and mitigate potential risks.
Hidden pillars
The report says that the UKโs most influential global providers arenโt just big-name technology firms โ they include niche software vendors that quietly power essential industries. The research identifies โHidden Pillarsโ; that is, lesser-known technology companies that serve large portions – or even the majority – of specific industries. A security failure at one of these companies could trigger cascading effects within and across industries. Customer count does not equal criticality, as some niche providers serve only a handful of companies yet support massive market share in industries like energy, finance, and logistics. Some of the most critical software and infrastructure providers operate with fewer than 50 employees, yet their technology is embedded in Fortune 500 companies and global enterprises.
Challenges
Organisations that supply digital products and services – known as providers – may face greater cybersecurity challenges than the businesses they serve. On average, providers use 2.5 times more products and have ten times more internet-facing assets globally, making them more exposed to cyber threats. While providers outperform consumers in four of six security standards โ including DMARC, SPF, DKIM, and DNSSEC โ they lag behind in areas such as patch management, open ports, insecure systems, and botnet infections. The UK is no different: businesses exhibit better cybersecurity performance than their providers. Moreover, regardless of provider size (as measured by market share) there are going to be some providers that fail to achieve or maintain a good security posture.
Ben Edwards, Principal Research Scientist at Bitsight, said: โOver the past year, weโve seen several highly-visible security incidents that highlight how incidents in the digital supply chain can have a massive ripple effect across the global economy. Even the most security-conscious companies are vulnerable to weaknesses in their supply chain. Organisations must continuously evaluate their third party vendors and suppliers and work proactively to close security gaps.โ
