arx technology

Working in challenging regulatory and operational environments and the need for rigorous compliance do not have to mean bespoke software development.

We have built a technology stack leveraging industry best practices for cyber security and using the latest micro service architecture and a generic, modular framework.

This technology stack is the foundation of Citadel, giving organisations a COTS capability with enterprise grade features - without the price tag of bespoke software

  • Data Encryption

    All data is held in secure UK data centers and is encrypted in transit and at rest

  • Customisable hierarchical access control

  • The BSI Kitemark for Secure Digital Transactions rigorously and independently tests websites or apps to make sure they have the security controls in place for the financial and/or personal information they are handling.

    It requires a website or an app to undergo rigorous and independent testing and producers of websites or apps from banking to entertainment can reassure their clients by displaying the BSI Kitemark on their product and in their marketing materials.

Our Story

We have a shared experience of working in some of the most challenging and demanding environments where successful risk management is critical to success. We know how difficult it can be to know and understand the full range of risks to which you might be exposed whilst trying to make the most demanding of operational decisions.

Having the ability to make the right call when weighing up the potential risks and benefits is a key differentiator.

Risk Management can be a resource intensive process. Procedures that require manual interventions and spreadsheets are slow and costly both in terms of the time they take and the financial cost.

Our founding belief and key motivator behind arx Partners is that the right technology will deliver secure, faster and better outcomes.

News and Views

Capturing accurate performance data that gives a true picture is difficult

Most of the companies with which we work will conduct regular risk audits. Whilst companies recognise the need to review their risk posture to assure themselves that the range of measures they have put in place are delivering their intended effect and that the company’s policies and procedures are being followed, their approach can vary significantly.

Our Founders

Richard Thompson

Managing Partner

following a thirty-three year career in government service dealing with some of the most challenging operational, policy and regulatory issues, I fully appreciated the importance of excellent risk management and the power of technology. Having the right technology in place can transform the speed and the quality of decision making.

Andrew Wood

Managing Partner

As an aviator, first as a helicopter pilot and continuing as a B747 Captain I was immersed in a highly regulated and risk-averse environment.
I started developing internet technology in 1998 when the web began to become popular. Utilising both skill sets I have guided the development team to produce the Citadel software.
