British businesses are no strangers to the ever-present cyber threats that we all face. Co-op, M&S, Jaguar Land Rover and Royal Mail are just a few of the recent targets of attempted (or, in most cases, successful) cyber attacks, and concerns are mounting that rapid technological advancements are escalating this threat even further.
We are, of course, referring to AI, and all the dangers that it presents for UK cyber security. Artificial intelligence has been a mainstay in global discourse for years now, but it’s currently in the headlines for all the wrong reasons as business, digital, and even national security specialists weigh in on the role of AI in cyber security.
Join us as we take a look at what these experts are saying, and how your business can prepare for the ever-changing cyber threats that are already more capable than you might think…
The New Cyber Threats Facing British Businesses
Up until just a few years ago, cyber attacks were a largely, yet not exclusively, human endeavour. Cyber criminals would often employ ransomware to assist in their activities, but the act of hacking required extensive skill, expertise, and input. It took time to force access into online databases or trick employees into handing over logins, which afforded the target company time to repair gaps in their online security or update their old systems before they were breached.
In 2026, the cyber protections of yesteryear are no longer enough to protect systems from increasingly severe and sophisticated attacks. Today, a new generation of AI models have all the rare expertise and technical knowhow of master hackers – only now they are able to wield this at speeds and scale that human cyber criminals were never capable of.
Once they receive an objective, these AI hacking models will assess a system’s vulnerabilities, write the code to exploit them, and continue to run tests until they have gained access. This AI threat to cyber security may be a new one, but it is developing at unprecedented rates; so much so that the UK government has recently published an open letter addressing the issue.
Open Letter to Businesses on AI Cyber Threats
On 15 April 2026, the Secretary of State for Science, Innovation and Technology and the Minister of State for the Cabinet Office released an open letter to all business leaders in the UK.
In this publication, The Rt Hon Liz Kendall MP and The Rt Hon Dan Jarvis MP laid out the threat of AI in online security, with particular emphasis on the remarkable and rapid advancement of its capabilities. Referring to the release of the new AI model Mythos, Kendall and Jarvis cautioned that the DSIT’s AI Security Institute (AISI) had found it to be ‘substantially more capable at cyber offence than any model we have previously assessed’. Concerningly, these findings reinforced the AISI’s assessment that AI cyber capabilities are doubling at a rate of every 4 months, rather than every 8 months as was previously believed.
This rapid acceleration of hacker-capable systems is predicted to continue over the next 12 months, and for many years after. Whether they’re used for reconnaissance, testing, or active infiltration, there is no denying that AI hacking models are a very present threat, and now is the time for British businesses to prepare their digital infrastructure for this new reality.
How You Can Protect Your Online Security
Every business with an online presence has software that is vulnerable to AI-assisted exploitation. That’s why all businesses are advised to take the following steps:
- Prioritise Cyber Security: Adhere to the Cyber Governance Code of Practice and use the NCSC’s Cyber Action Toolkit to develop a cyber security strategy. This should also include a crisis management plan to be implemented in the event of a significant incident.
- Sign Up for Cyber Essentials: This government-backed certification scheme helps businesses to avoid the most commonly exploited cyber security weaknesses. Free cyber insurance is also available to the organisations that obtain this certification.
- Follow NCSC Advice: Follow the National Cyber Security Centre (NCSC) Cyber Assessment Framework and sign up for their Early Warning Service to receive alerts of potential cyber threats.
How The Government Will Protect Your Online Security
As part of this united defence, the UK government has implemented the following initiatives to protect critical infrastructure and systems:
- The AI Security Institute: Hailed as the most advanced government-owned institute in the world for the study of AI systems and their capabilities.
- The National Cyber Security Centre: As part of the Government Communications Headquarters, the NCSC provides government bodies and public organisations with cyber security advice and support.
- The Cyber Security and Resilience Bill: Introduced in November 2025 as an addition to the Network and Information Systems (NIS) Regulations, this bill will better strengthen UK public services against cyber attacks.
- The National Cyber Action Plan: Presented to Parliament just last month, this plan sets out the government’s cyber security strategy which will be delivered by the Government Cyber Unit.
