Guernsey - GFSC Dear Ceo - review cyber defences amid faster AI-driven vulnerability discovery

The Guernsey Financial Services Commission (GFSC) has issued a Dear CEO letter to the firms it regulates, highlighting the need to review technology risk management in light of rapid advances in frontier artificial intelligence.

The letter, dated 3 July 2026 and signed by Conor Osborough, Director of Technology, does not introduce new rules or heavy additional burdens. Instead,

• It serves as a timely reminder that AI tools are now capable of identifying software vulnerabilities including in large, complex and legacy systems  at a speed and scale previously unattainable.

These capabilities:

• Can strengthen cyber resilience when used responsibly by defenders,
• But they are also likely to accelerate the discovery of exploitable weaknesses by threat actors.

Key points from the GFSC announcement

The Commission states that recent international developments show both opportunities and risks from fast-moving technology.

• AI tools do not necessarily create new weaknesses;
• they expose ones that already exist in the systems financial firms, their customers and markets rely on.

The Bailiwick of Guernsey’s principles-based regulatory framework is designed to support innovation without stifling it. At the same time, it places clear responsibility on firms to treat technology risk as an evolving exposure that requires ongoing monitoring, review and updates not a static issue.

Firms are specifically encouraged to:

• Understand and assess whether their IT patching regime remains appropriate, particularly if weaknesses now need to be fixed in a significantly shorter timeframe without weakening checks and controls.
• Ensure any third-party outsourced providers can meet these changing demands.

The GFSC notes it has consulted international counterparts and experts in AI and quantum computing, who broadly agree that these technologies are advancing faster than expected even a year ago, with threats increasing.

What this means for consumers

If you bank, invest, insure or use other financial services provided by firms regulated in Guernsey, this update is ultimately about protecting your data, accounts and transactions from cyber threats.

By prompting firms to proactively review vulnerability management, patching speed and third-party oversight, the GFSC is seeking to reduce the window of opportunity for attackers who may increasingly use advanced AI tools. Stronger, faster maintenance of systems should help keep customer information and money more secure.

This is not an announcement of any specific incident, breach or immediate crisis affecting customers. It is precautionary regulatory engagement, consistent with the GFSC’s existing approach of encouraging responsible innovation (as set out in its January 2026 Policy Statement on the Use of Artificial Intelligence) while expecting firms to manage the risks that come with new technology.

Balanced perspective

The letter explicitly states the Commission does not want to “heap new burdens on firms”. It frames the request as a proportionate response to genuinely fast-moving technological change rather than a reaction to any single event. Consumers should view this as standard, good-practice supervision rather than a signal of heightened immediate danger.

Firms that already maintain robust, proactive technology risk frameworks are unlikely to face major new operational disruption. Those that have treated patching or third-party oversight as low-priority or static processes may need to accelerate improvements.

If you have specific concerns about a Guernsey-regulated firm you use, the most direct step is to contact that firm and ask how they are addressing technology and cyber risk management. Regulated firms are expected to be able to explain their arrangements to customers.

READ THE ACTUAL UPDATE

GFSC issues Dear CEO letter on technology risk 8th July 2026 General

Advances in frontier artificial intelligence (“AI”) models are reshaping the cyber risk landscape. These models are increasingly capable of identifying software vulnerabilities, including within large, complex and legacy code bases, at a speed and scale that was previously unattainable. Whilst these capabilities have the potential to enhance cyber resilience when used responsibly, they are also likely to accelerate the discovery of exploitable weaknesses across digital infrastructure.

The Commission does not want to heap new burdens on firms. Rather we have spent some time talking and listening to international counterparts and experts in the fields of AI and quantum computing all of whom seem to concur that these society changing technologies are advancing markedly faster than expected even a year ago, with threats increasing. In these relatively unprecedented circumstances we think it is proper to ask the leaders of the firms we regulate to review their technology risk management arrangements, including vulnerability management, patching processes and third-party oversight. The accompanying Dear CEO letter which we have issued to firms highlights relevant matters.

3 July 2026

Dear CEO

Ongoing Technology Risk and the Use of Advanced Vulnerability Discovery Tools

The Commission supports innovation and recognises the role that Artificial Intelligence (“AI”), in all forms, could play in transforming the way financial services are administered, managed and delivered at all levels (Policy Statement – Use of Artificial Intelligence  GFSC).   

Recent international developments, including the use of advanced AI tools to identify vulnerabilities within existing software, have demonstrated both the opportunities and risks arising from rapidly advancing technology. 

The Commission notes that such tools do not necessarily create new weaknesses; rather, they expose ones that already exist within systems relied upon by firms, customers and markets. This discovery capability can materially improve defensive arrangements, but it also reinforces the importance of continuous and proactive maintenance of technology environments. 

The Bailiwick’s principles‑based regulatory framework is deliberately designed to enable firms to embrace technological change without inhibiting innovation. It also places a responsibility on firms to ensure systems that are in use are subject to ongoing review and updates where appropriate. Firms should be satisfied that technology risk is not treated as static, but as an evolving exposure, requiring ongoing monitoring. 

It is important that the firms, understand the IT patching regime in place for its organisation, and that it remains appropriate, especially if, with recent developments, there is a need to rectify weaknesses in a significantly shortened timeframe without reducing checks and controls. If a firm is using a third-party outsourced provider, they should ensure that this outsourced provider is able to meet the ongoing needs of the firm with respect to this changing environment.  

I should be grateful if you could bring this letter to the attention of your Board and senior management.  

Yours sincerely, 

Conor Osborough
Director of Technology
