Trust Centre

On 21 October 2026, a vulnerability affecting technology that uses PHP code was publicly reported and has been widely reported in the media.

We are currently undergoing active investigation and, where required, remediation. Since the vulnerability was reported, we have been validating our initial assessment and applying remediation or mitigation where our investigation indicates it is needed. Our investigations are progressing, however, given the size and complexity of our product and infrastructure estate, further time is required before we can confirm our position.

As part of our investigation, we are:

Identifying where PHP is used across our products and supporting infrastructure, including the versions in use

Reviewing the full advisory as soon as it is published and assessing our exposure against it

Prioritising remediation or mitigation in line with our vulnerability management process

Monitoring for any indication of exploitation.

We will provide regular updates regarding this vulnerability on our website www.oneadvanced.com/PHP, including any notable changes, our confirmed position and any action required by you.

If you have additional questions, please contact our Service Centre in the normal way go to https://oneadvanced.com/service-centre

We’re proud to share that OneAdvanced has achieved ISO 42001 certification, the new international standard for Artificial Intelligence Management Systems. This places us among the first UK-headquartered SaaS providers to be independently certified against a global benchmark for responsible, trustworthy AI.

Why this matters:
ISO 42001 sets rigorous expectations for how organisations govern, design, deploy and monitor AI. It covers transparency, security, ethics, risk management and continuous improvement. Achieving certification demonstrates that OneAdvanced has the structures, controls and safeguards in place to ensure AI is used safely, responsibly and at scale across our products, platforms and internal operations.

Why this matters to customers:
For customers, particularly those operating in highly regulated sectors, ISO 42001 is a powerful trust signal. It provides external validation that OneAdvanced meets a recognised standard for AI governance at a time when organisations are under growing regulatory, contractual and ethical pressure to evidence how AI is used, and clearly differentiates us in the UK SaaS market as that trusted partner.

More broadly, this milestone reflects the maturity of our organisation. It reinforces our commitment to responsible innovation, strong data governance, and building technology that evolves in line with emerging regulation and societal expectations. It also equips our teams and customers with the ability to adopt AI with confidence, clarity and control.
