Cyber security services for UK businesses

Protect the people, systems and data your business relies on. Systems Assurance brings together security assessments, managed detection and response, cloud and endpoint protection, and incident support.

Whether you need to address a specific gap or strengthen your ongoing protection, we help you choose and put in place support that fits your organisation.

Discuss cyber security

Understand your risks

Identify weaknesses and focus improvement work where it will make the most difference.

Strengthen detection and response

Combine security technology with the expertise needed to investigate threats and take action.

Support the way you work

Protect business devices, remote users, cloud services and sensitive data as your organisation changes.

Practical cyber security, from assessment to ongoing support

Security needs to work across the whole business: the devices people use, the accounts they sign in with, the applications they access and the information they share.

We help you understand how those areas connect and where protection needs to improve. Start with a security assessment, bring in specialist help for a project or build a managed service around your existing IT team. You get clear priorities and an agreed plan for putting the right controls in place.

Your proposal confirms the services included, systems covered, monitoring hours, response arrangements and responsibilities.

Cyber security services built around your requirements

Cyber security assessments and testing

Find out where your organisation is exposed and what to tackle first. We help you review security controls, assess cyber maturity and arrange penetration testing where appropriate. Clear findings and prioritised recommendations give your team a practical basis for improvement.

Managed detection and response

Cyber security assessments and testing

Bring monitoring, threat investigation and response together in one managed service. Options include 24/7 monitoring from a UK security operations centre, with specialists who investigate suspicious activity and support the agreed response.

Endpoint security and extended detection and response

Protect business devices and connect security information from across your environment. Extended detection and response, or XDR, brings together signals from endpoints, identities, email and cloud services, helping security teams investigate related activity and focus on threats that need attention.

Cloud security and vulnerability management

Identify security gaps across cloud services, business systems and applications. We help you find misconfigurations and vulnerabilities, prioritise them by business risk and track the work needed to address them. Ongoing reviews help keep protection aligned with changes to your environment.

Secure access and identity protection

Give employees access to the applications they need while keeping permissions under control. Support can include stronger identity checks, privileged-access controls and zero trust network access. The aim is to protect remote and hybrid working while making everyday access manageable.

Incident response and recovery

Prepare for cyber incidents with a clear plan and access to specialist support. We help establish response procedures, escalation routes and recovery priorities, with incident-response retainers available as part of an agreed service. Coverage and responsibilities are set out before you need them.

Protect your people and business information

Email security and staff awareness

Reduce exposure to phishing, impersonation and compromised email accounts. Combine email protection with practical staff guidance and phishing exercises, helping people recognise suspicious requests and know how to report them.

Data security for cloud and AI

Email security and staff awareness

Understand where sensitive information is stored, who can access it and where it may be exposed. Data discovery, classification and access controls help you protect business information and prepare for tools such as Microsoft 365 Copilot and other AI applications.

Common questions about cyber security services

Can we start with a single assessment or project?

Yes. You can start with a specific requirement, such as understanding your current risks, testing a system or improving access controls. The findings can then inform further work or an ongoing managed service where it is useful.

Can you work alongside our existing IT team or provider?

Yes. The service can support the people and systems you already have in place. We agree who monitors, who makes decisions and who carries out changes, so the additional support has a clear role.

What is the difference between MDR and XDR?

Managed detection and response, or MDR, is a service that combines monitoring, investigation and response. XDR is technology that connects security information from several sources. An MDR service may use XDR as part of its delivery.

Can you help us prepare for an audit or customer security review?

We can help assess current controls, identify gaps and organise evidence of the improvements made. The work is shaped around the requirements you need to address, with the assessment scope agreed at the outset.

How much do cyber security services cost?

The cost depends on the systems and users covered, the work involved and whether you need a defined project or ongoing support. We confirm the proposed services and charges before work begins.

What should we include in our enquiry?

Tell us your main concern, the systems involved and your timescale. Approximate user or device numbers and details of your existing IT support will help us identify a useful starting point.
