Hytec Information Security: Specialist N3 Consultancy and Managed Services 

Hytec, OLM’s specialist information governance and security division, provides services to support NHS N3 Connection, IGSoC ToolkitPSN connectivity and ISO 27001 certification.

Hytec information security is trusted by many local authorities and organisations for delivering clear, workable advice regarding NHS N3 compliance and matters of information security.

Organisations wishing to provide services to Health via the NHS N3 network, manage devices, or administer applications on the N3 network, need to comply with the technical and Information Governance requirements of the NHS in order to be able to communicate via N3.

From our five offices, Hytec information security provides N3 Connection consultancy and other data security services to local authorities and private organisations across the UK.  

We are true N3 service experts with over 25 years security/information governance experience. We have provided specialist services providing IGSoC Toolkit Compliance services and connecting hundreds of organisations to a secure, resilient N3-connected hosting environment. We build relationships based on flexible, friendly partnerships and the cost-effective delivery of information security related services and hosting, such as N3 and PSN.

Commercial N3 Aggregator

Hytec is approved by The Health and Social Care Organisation (HSCIC) to act as a “Commercial N3 Aggregator” meaning we can order N3 circuits for our clients, share N3 circuits amongst clients and approve technical designs.

What is N3 Aggregation?

N3 Aggregation is defined as the provision of N3 connectivity (from a single or multiple N3 circuits) by one organisation to one or more other organisations.  As the NHS N3 network is exposed to this new method of providing connectivity to end user organisations, the levels of risk exposure increase correspondingly. It is therefore acknowledged that the standard Information Governance Statement of Compliance (IGSoC) process must be enhanced to include additional requirements for organisations wishing to provide aggregated N3 connectivity to their customers.

Hosted N3

Hytec has a wider team offering a range of expertise in infrastructure design and managed N3 hosting services. OLM’s client base is largely formed of local government, health authorities and commercial organisations. For these clients, the initial engagement usually occurs when connection to private or secure networks and compliance with security standards are required.

The interface between the N3 network and the external internet is managed and controlled in the Hytec hosted environment. This is housed in a TIA 942, Tier 3 high security, high availability N3 compliant data centre. A typical environment consists of a server sitting within a secure DMZ created between two suitably assured firewalls, one facing the internet, the other facing the N3 network. Access to clients’ hosted systems by Hytec support staff and the clients’ support staff is via secure two factor authentication. 

Hytec ensures that the whole environment operates in compliance with NHS N3 standards, for example:

  • Use of suitably accredited firewalls (EAL4)
  • Retention of logs for the required time
  • Use of Two factor authentication for secure access and for non-repudiation

For our N3 hosting, Hytec operates a 24-7 helpdesk and has mature procedures and policies that enable the efficient management of incidents. Our change management processes are flexible enough to allow us to accommodate the working practices of our clients but which also allow Hytec to control access to the N3 hosted system on their behalf. Many of these processes integrate with the information governance processes and policies of our clients.

Leaders in N3

Hytec is one of the few organisations suitably qualified to advise care organisations and local authorities on matters relating to IT security (PSN, N3 infrastructure design). With over 25 years experience of providing N3 connection advice and N3 hosting to Health organisations and local authorities Hytec is seen as a trusted partner.

Hytec consultants are heavily involved in the area of information assurance.  They are aware of, and continually monitor changes to the many “baseline” standards that exist in the UK.  They also contribute regularly to speaking engagements when information assurance is on the agenda.

Knowledge is gathered from many sources such as The Cabinet Office, CESG, NHS, DoH and PSN.  Information is also gathered from other reliable information sources regarding new or emerging threats and vulnerabilities, such as CERT and NIST.
