Cyber Attacks Pressing Concerns for UK Critical Infrastructure, Report Shows
Recent research by Bridewell has revealed a troubling trend in cyber security, indicating that cyber attacks have impacted nearly every organization within the UK’s critical infrastructure (CNI). A staggering 93% of these organizations reported experiencing a cyber incident over the past year. This alarming statistic comes from Bridewell’s comprehensive report entitled Cyber Security in CNI Report 2026, which sheds light on the escalating scale and impact of cyber threats across vital sectors including energy, finance, transport, and government.
The findings illustrate that cyber incidents are increasingly causing significant real-world disruptions. Notably, half of the organizations surveyed admitted to experiencing IT outages or operational disturbances directly attributable to cyber attacks. Furthermore, nearly one-third of those organizations reported suffering financial losses as a result of these incidents. Such revelations underscore the urgent need for enhanced cyber resilience in sectors that are pivotal to the UK’s economic stability.
Analysis of the types of attacks reveals that phishing and business email compromise (BEC) are the predominant attack vectors, with organizations encountering an average of 11 phishing or BEC incidents per year. Malware attacks also remain a significant threat, averaging about eight incidents annually. In the face of this persistent threat landscape, the report notes that data protection and privacy remain paramount concerns, with 43% of respondents identifying them as significant issues.
One noteworthy development highlighted in the report is the rise of AI-related cyber risks, which have now entered the upper echelon of security concerns for CNI organizations. Approximately 39% of respondents recognized AI as a critical issue, a reflection of the increasing utilization of AI tools by threat actors. These malicious entities are exploiting AI to enhance and scale their attacks, particularly in the realms of phishing and malware development. In response, organizations are also quickening their own AI adoption to bolster their defenses.
More than one-third of organizations reported utilizing AI technologies to automate incident response, while a similar number are employing AI tools to enhance threat hunting efforts. Martin Riley, the Chief Technology Officer at Bridewell, emphasized the central role AI is beginning to play in cyber defense strategies. Riley noted, “AI is now central to modern cyber defense. If you are not using AI to accelerate detection and response, you are falling behind attackers who are already using it against you.” He further posited that the challenge moving forward would not be about whether to adopt AI, but rather, how to manage it responsibly and safely.
Anthony Young, the CEO at Bridewell, echoed these sentiments, drawing parallels between AI adoption today and the early days of cloud computing. He warned that while AI offers immense potential, it is often integrated into systems faster than the necessary security controls can be put in place. Young stressed the importance for organizations to apply the same level of discipline and protective measures to AI as they expect for cloud services and digital infrastructures.
In a notable shift, the research also indicated that regulatory demands are now more influential in driving cybersecurity investment than cyber threats themselves. For the first time, 35% of organizations cited regulatory requirements as the primary reason for enhancing their cybersecurity measures, an increase from 26% the previous year. However, the report also indicated a concerning inconsistency in how organizations implement essential frameworks. Less than half of those surveyed reported having adopted or complied with the Cyber Assessment Framework, while even fewer acknowledged compliance with NIS2.
The gap in compliance is reflected in the confidence levels of organizations, with 39% admitting to low confidence in their cybersecurity measures concerning data protection. Young pointed out the importance of adhering to frameworks, stating, “Frameworks are essential, but compliance on paper does not automatically translate into operational resilience. Regulators are asking harder questions, and organizations will need to demonstrate policy alignment as well as real-world capability.”
The report does not shy away from addressing emerging risks, revealing a growing disconnection between perceived preparedness versus actual readiness in areas such as post-quantum cryptography (PQC). While 90% of organizations claimed to feel prepared for PQC, over a third admitted they have yet to review relevant government guidance. Bridewell characterized this phenomenon as “confidence without clarity.”
In conclusion, Bridewell posits that 2026 marks a critical juncture for cybersecurity within the domain of critical infrastructure. With significant disruptions affecting half of the organizations surveyed and attacks becoming more frequent and sophisticated, the report advocates for a shift from mere awareness to active execution in response to cyber threats. “The speed of attack now outpaces traditional response models,” said Riley. He pointed out that the organizations best positioned for success will be those that can detect attacks swiftly, respond in mere minutes, and manage emerging technologies such as AI securely.
