What is an IT Health Check?

An IT Health Check (ITHC) is used to confirm that your information systems and network meet a specified baseline standard. Also known as Codes of Connection (CoCo), these rules are used by organisations like the NHS and the Gambling Commission to ensure only trusted partners are able to exchange data online.

The ITHC provides assurance to your partners that internal and external systems are protected from unauthorised access. This includes wireless access points which connect to the internal network and remote working devices, such as company smartphones. You will need to complete an ITHC once per year – or risk losing access to these trusted resources, such as the NHS Public Service Network (PSN).

Why do I need an IT Health Check?


Your partners operate a CoCo

If your partner applies a Codes of Connection (CoCo), you have no choice – an annual IT health check is a non-negotiable requirement of doing business with them.


You plan to connect to the NHS PSN

If you plan to supply goods or services to the NHS, you will need to ‘earn’ a Public Service Network (PSN) certificate. To do that your IT security systems will need to pass a penetration test carried out according to a specific government standard.


You must renew your PSN certificate

The PSN certificate that grants access to NHS digital resources must be renewed once a year. If your certificate expiry date is approaching, you will need to arrange for a fresh IT health check.

Our Approach

External security scan

The ITHC assesses security provisions at all levels of your network, starting with external facing assets. Our consultants check VPNs, email portals and websites meet the specified government standards.

Internal security scan

Shifting attention to your internal network, consultants will then test at least 10% of your servers and PCs for vulnerabilities that could be exploited. We will also check wireless network configuration to ensure it has been properly secured.

Firewall review

Engineers will ‘attack’ the firewall between your network and the PSN to confirm resilience and integrity. We will also review the rules and configurations of your main firewall to ensure all-round network security.

Device configuration review

To limit potential attack surfaces our consultants will audit desktop and server builds, checking for vulnerabilities. We will also assess your mobile device management (MDM) systems to confirm that smartphones, tablets and laptops are secured in accordance with the relevant CoCo requirements.
