Choose the Right Level of Support
Three clear routes, from a single fault through to ongoing technical oversight. We will confirm scope and commercial details with you directly.
SLA Support Agreement
For customers who need help with a specific fault, configuration issue or technical requirement. This may include remote support, site attendance, fault diagnosis and corrective work.
Planned Maintenance Contract
Scheduled maintenance visits and technical support designed to improve system reliability and reduce unexpected failures. The agreement can be tailored to the customer's sites, equipment and operational requirements.
Managed Technical Support
Ongoing support for organisations that need regular system administration, troubleshooting, reporting and technical oversight. This may include remote monitoring, user administration, system reviews, vendor coordination and agreed response arrangements.

Support Across Your Security Environment

We Can Assess Systems Installed by Other Providers
Support is not limited to systems installed by Core Guard Group. If your existing installer is unavailable, your system is unreliable or your organisation has inherited an ageing security environment, Core Guard Group can conduct an initial assessment.
We will identify the equipment, review the current condition and recommend whether the system should be repaired, supported, integrated or replaced in phases.
