Our Cyber Security Offerings

Cyber Security as a Service

CSaaS allows the outsourcing of services or business risks to be managed on your behalf.

Nine23 accomplish this through a combination of using our highly skilled people embedded alongside your personnel, our ISO 27001 compliant processes and the management and deployment of suitable cost-effective technology, either your own tools or additional technology that we deploy and manage on your behalf.

Zero Trust

Ensuring business continuity, zero trust is an important step in your Cyber Security strategy.

Zero Trust models are increasingly coming to the fore to mitigate common cyber threats and help increase levels of assurance that systems and data are being accessed appropriately. Our team will work with you to identify the advantages of adopting Zero Trust approaches or whether alternative security patterns can offer you more appropriate protections.

Define, build and manage your cyber security needs

Implementing a cyber security strategy is of benefit to any organisation. Nine23 can help to define and/or review your current cyber security strategy to prioritise investment decisions and ensure that the focus is on the best outcome for you and your business.

Nine23 can help you define your strategic threat assessment, maturity assessments of people, processes and technology within the organisation, strategic implementation planning and roadmap development.

We offer support on your journey to ISO 27001 adoption or the implementation of the NIST Cyber Security Framework (CSF) with a readiness assessment, implementation strategy, scope and maturity model.

We can help you optimise your portfolio of tools, services and partners to maximise the value from your existing investment. 

We will work with your senior stakeholders to define and agree risk appetite and tolerance statements against which risk levels can be managed through controls and resources. 

Building your cyber security needs with Nine23 covers design, development and delivery whilst maintaining your regulatory and compliant needs, as required.

This includes the assessment and selection of tooling with full technical and commercial assessments of at least 3 products, fully compliant with the Technology Code of Practice, Treasury Green Book and broader Public Sector spend controls. These can be delivered independently or as part of the development of a business case to support investment decision making.

As needed, Nine23 can implement the tooling within the client environment (or within our own secure UK sovereign private cloud and connect it to the client environment) or work with your own delivery teams (internal or outsourced) on the design and implementation, providing assurance that this has been done to identified standards. As part of this can help develop, test and optimise automation playbooks on business meaningful risks and activities to reduce the demand on your existing security teams freeing them for higher value activities such as threat hunting, supply chain audit, working with your engineering teams to eliminate threats early in service delivery etc. 

We can aid you in the mapping and threat modelling of your supply chain and work with you to define a full supply chain risk assessment, management methodology, reporting and audit mechanism. We can also audit parts of your supply chain as a trusted 3rd party in support of your regime as appropriate. 

By managing your cyber security needs with Nine23 our goals become your goals and we align all of our services to client business metrics.

In the cyber security service this will typically be around the reduction and ongoing management of risk against your organisational appetite and tolerance. We seek to reduce the total cost of ownership of your security capability through the optimisation of tooling and services. We work to ensure delivery is closely integrated to minimise commercial and service gaps and maximise the derived value from committed spend. 

Nine23 and our carefully selected group of strategic partners can manage end-to-end risk management services on behalf of your organisation including: 

  • Managed Cyber Security Service
  • Security Operations Centre (SOC) – Hybrid or full outsource
  • Managed Detection and Response (MDR) – covering endpoints, networks, Cloud tenancies, on-premise environments and SaaS services
