How we do it

The purpose of a business is to deliver value to its customers through the provision of services or products. Or, in the case of the public sector, to serve citizens through the delivery of public services. The backdrop to all of this is that most of these business and organisations rely on information and information technology and this introduces risks. Cyber attacks are growing more frequent, sophisticated and damaging. The danger is that security is applied without thinking about its impact on the business resulting in security becoming a barrier. Our approach is based on understanding the business purpose (vision and objectives) and aligning security to this so that it enables the business purpose rather than hindering it.

We strongly believe that security should be ‘good enough’ to enable the business to win i.e. to enable the business to do what its exists to do. There’s no point in having excellent security if the business is unable to operate. Good enough security is risk based, ensuring that security is proportional to the risks faced.

Who we work with

Our clients range from small start up businesses to global enterprises across multiple sectors. We work with half of the fire services and a third of the Police forces in the UK as well as local authorities, government departments, energy/utility providers, health, charities, housing associations and manufacturing.

Our consultants are involved in national programmes as independent security advisors/assurers and have experience in supporting complex IT environments including hosting in Azure, AWS and private clouds.

Why Aristi

Aristi is an ISO 27001 and Cyber Essentials Plus certified business and holds NCSC CHECK status for penetration testing services.

We focus on assisting our clients to achieve real value from information security rather than it becoming a ‘tick box’ exercise and a burden to your business. We achieve this by understanding your business needs and supporting the development and implementation of proportionate and appropriate security controls.

We work with clients across multiple sectors which allows us to draw upon an extensive knowledge base of good practice which we openly share with our clients.

Our aim is to develop trusted and mutually beneficial partnerships where we become an extension of your internal team and act as a ‘critical friend’.
