Onboarding and offboarding

Getting started
We follow a defined process for on-boarding new clients to ensure that they have the assurance of our help, whilst at the same time remain in control of the cloud services which are often at the core of their business.

Through the on-boarding process Nexus will complete a detailed assessment of:

• Client’s strategic vision
• Organisational culture
• Current and future objectives
• Desire business outcomes
• Potential improvements to existing business processes
• Project and programme delivery resources
• Current governance and programmes.

We can provide onsite training to our clients as well as instruction at our own training centre. User documentation is provided by way of client portal guide.
Service documentation
End-of-contract data extraction
The Azure Import/Export service allows you to securely transfer large amounts of data to Azure blob storage by shipping hard disk drives to an Azure data center. You can also use this service to transfer data from Azure blob storage to hard disk drives and ship to your on-premises site.

When customers delete data or leave a Microsoft cloud service, Microsoft follows strict standards for overwriting storage resources before reuse, as well physical destruction of decommissioned hardware, including
contractual commitments to specific processes for the deletion of data and the destruction of storage hardware.
End-of-contract process
There are no additional costs at the end of the contract.

Azure Backup is the Azure-based service you can use to back up and restore your data in the Microsoft cloud. Azure Backup replaces your existing on-premises or off-site backup solution with a cloud-based solution that is reliable, secure, and cost-competitive. Azure Backup offers multiple components that you download and deploy on the appropriate computer, server, or in the cloud. The component, or agent, that you deploy depends on what you want to protect. All Azure Backup components can be used to back up data to a Backup vault in Azure.

Operational security

Configuration and change management standard
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Configuration and change management approach
Nexus have a configuration management process for tracking changes in the specification of our services and products, this is managed centrally. Nexus also implement a full change management process for assessing and if appropriate executing any changes to services and products.
Vulnerability management type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach
One key operational best practice that Microsoft uses to harden its
cloud services is known as the “assume breach” strategy. A dedicated “red team” of software security experts simulates real-world attacks at the network, platform, and application layers, testing Azure’s ability to detect, protect against, and recover from breaches. By constantly challenging the security capabilities of the service, Microsoft
can stay ahead of emerging threats.
Protective monitoring type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach
Microsoft security researchers are constantly on the lookout for threats. They have access to an expansive set of telemetry gained from Microsoft’s global presence in the cloud and on-premises. This wide-reaching and diverse collection of datasets enables Microsoft to discover new attack patterns and trends across its on-premises consumer and enterprise products, as well as its online services. As a result, Security Center can rapidly update its detection algorithms as attackers release new and increasingly sophisticated exploits. In the event that customer data is compromised, Microsoft will notify its customers.
Incident management type
Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach
All Incident tickets will be recorded in the Nexus Service Desk system under the Incident Management workflow. All new Incident tickets will undergo an initial impact assessment. Nexus will further look to determine the number of users/systems affected and establish the commercial impact to the customer’s environment. We have a knowledge base to be able to check for common events. Users can report incidents by phone, email or through their client portal. Incidents are included in any appropriate service monthly ticket summary reports.

Social Value

Fighting climate change

Fighting climate change

The environmental benefits of our G-Cloud Service provision for Cloud Hosting Services utilising Microsoft Azure are substantiated by Microsoft’s own studies and commitments towards climate change.

A 2018 study found that using the Microsoft Azure cloud platform can be up to 93% more energy efficient and up to 98% more carbon efficient than on-premises solutions.

Azure has committed to focus on four key areas of environmental impact to local communities; carbon, water, waste, and ecosystems by way of; using 100% renewable energy by 2025 by partnering with renewable energy projects, replenishing more water than they consume by 2030, achieving zero-waste certification by 2030 and achieving net-zero deforestation from new construction and re-forestation initiatives by greening communities with native woodlands.

Real sustainability requires solutions that address wastefulness at every level of a business. Hosting on the cloud is more environmentally friendly and results in less of a carbon footprint.

Cloud infrastructures support environmental proactivity, powering virtual services rather than physical products and hardware, and cutting down on paper waste, improving energy efficiency, and (given that it allows employees access from anywhere with an internet connection) reducing commuter-related emissions.

Reports predict that data centre energy consumption would drop by 31% from based on the adoption of cloud computing and other virtual data options.
Covid-19 recovery

Covid-19 recovery

As a member of the COVID-19 High Performance Computing Consortium, Microsoft is helping researchers accelerate their understanding of the virus and the development of treatments and vaccines through two major initiatives; HPC Consortium and AI for Health.

The COVID-19 HPC Consortium encompasses computing capabilities from some of the most powerful and advanced computers in the world. Microsoft hope to empower researchers around the world to accelerate understanding of the COVID-19 virus and the development of treatments and vaccines to help address infections. Consortium members manage a range of computing capabilities that span from small clusters to some of the very largest supercomputers in the world.

AI for Health is a new $60 million, five-year philanthropic program from Microsoft, created to empower non-profits, researchers, and organizations tackling some of the toughest challenges in global health. Microsoft are providing access to AI and expertise in these areas; Accelerating medical research to advance the prevention, diagnoses, and treatment of diseases, increasing our shared understanding of health and longevity to protect against global health crises, reducing health inequity and improving access to care for underserved populations and supporting fundamental research capabilities, including data collaboratives and differential privacy.


The primary benefits of Microsoft Azure services are the transfer of ownership of compliance and maintenance of cloud infrastructure and its security and that IT Managers and business owners no longer need to be concerned about those elements of their IT systems once in Azure.
This inherently has a significant positive impact on wellbeing of employees within organisations across the world.
