Hostile cyber activity in the UK is intensifying at an unprecedented rate, posing a direct risk to business operations and national security. High-profile incidents have underscored the severe financial, operational, and reputational consequences faced by organisations across all sectors. Yet, one of the most persistent and dangerous risks remains shrouded in silence: the insider threat.
Internal Risks: The Elephant in the Room
Insider threat is a universal risk—one that few organisations are willing to discuss openly. As Senior Security expert Michael Robinson aptly notes, “We share information about ransomware and nation-state attacks, but there’s almost no collective learning and sharing about insiders. Companies treat it like a dirty secret.” While many assume threats come solely from disgruntled or underperforming staff, uncomfortable research now reveals a deeper truth: it’s just as likely to originate at the top. Nearly a quarter of malicious insiders are senior executives, and almost 20% are high-performing insiders trusted with critical access. These findings demand frank acknowledgment and immediate action.
Hidden Risks Linger Long After Staff Depart
Even after staff or executives leave, many retain risky access to sensitive systems—especially as cloud tools, shared credentials, and remote logins fall outside of typical IT visibility. The message is clear: relying on optimism or anecdote is not enough. Effective protection demands rigorous, evidence-based governance, rapid deprovisioning for leavers, and the courage to recognise that insider risk is present in every organisation.
Three Actions to Strengthen Board-Level Cyber Resilience
The UK government has responded with actionable, evidence-based steps designed to help you shield your most critical assets from a cyber attack:
- Make Cyber Risk a Board Priority
Adopt the Cyber Governance Code of Practice, developed with industry leaders, setting out critical actions Boards and Directors should take to govern cyber risk effectively. The Code is supported by free training, which all Board members are encouraged to complete to strengthen their oversight.
- Register for the NCSC Early Warning Service
This free government service provides advanced alerts of potential cyber attacks—giving you invaluable time to detect and stop a cyber incident before it escalates.
- Mandate Cyber Essentials Certification in Your Supply Chain
Supply chain cyber-attacks are rising, yet only 14% of UK businesses assess risks from their immediate suppliers. Cyber Essentials, the government-backed certification, sets a minimum standard and certifies organisations have key protections to prevent common attacks. Businesses holding Cyber Essentials are 92% less likely to make a claim on their cyber insurance, dramatically reducing third-party and insider attack risks for themselves and their partners.
Implementing Cyber Essentials technical controls across your systems is vital for a resilient, strategic defence.
Embedding these practices will drive robust governance, reduce invisible risks, and safeguard your organisation for the long term.
Lead with Evidence, Not Anecdote
Cyber risks don’t discriminate by rank, department, or tenure—optimism is no defence. Effective boards invest in vigilant access management, swift revocation of entitlements for leavers, and use of identity analytics to uncover and remediate risk patterns before they become incidents. As Robinson warns, “Everyone thinks they understand insider risk, but the data shows otherwise”. Hacker Conversations: Rachel Tobac and the Art of Social Engineering – SecurityWeek
