Endpoint monitoring services aim to understand, at a granular level, what is happening directly on IT endpoints and have become increasingly important in defending IT estates. As cyber adversaries continue adapting with changing tactics and threats, these services deliver a high level of accuracy in detecting vulnerabilities via behaviour analysis and identification of irregular data to mitigate cyber threats.
HBC is software suitable for OFFICIAL devices, collecting technical metadata for analysis by the NCSC.
Primarily available to the UK’s central government, provision of HBC is considered on a strategic case-by-case basis. These are usually received as internal NCSC referrals.
HBC's three-part service model seeks to provide value to government through:
Our Threat Surface reporting provides cyber security metrics to organisations regarding their cyber hygiene. We work with organisations to provide information that is insightful and actionable.
We seek to warn our organisations about major vulnerabilities that they may be exposed to. We use the data collected to understand each organisation’s exposure and inform them of our findings to help them take quick remedial action; identifying which devices have the vulnerability, which are not patched and providing independent assurance of which are effectively patched.
HBC benefits departments through:
HBC is offered as a service to enhance your security posture alongside other tools/services; we do not recommend that you use HBC to rationalise other security products/tools on your estate.
If you think you are eligible for HBC, please speak to your main NCSC point of contact in the first instance. If you do not have a contact, please email [email protected].
If HBC can be provided to you, an agreement which explains the terms and conditions under which we can provide HBC must be signed. The HBC Team will work with you on all the steps and requirements to implement a rollout.
It is important to note that whilst HBC is free at the point of use from the NCSC, any implementation costs (e.g. change request fees) will need to be covered by the recipient organisation.
