CoreGov – SIEM as a Service

SIEM as a Service transforms machine data into real-time operational intelligence. It enables organisations to search, analyse, monitor, visualise and act on massive streams of data generated by websites, applications, networks, mobile and other devices. The platform includes IT Operations and Service Intelligence, Security and Compliance, and Big Data Analytics.


  • Analyse ‘big data’ internet traffic and machine data
  • Monitor performance of network infrastructure against Service level Agreements
  • Real-time network intelligence, avoid costly network escalations/downtime
  • Detect and reduce internal and external cyber threats/abuse
  • Provide effective security compliance and reduce costs
  • Proactively monitor clients/users understand and anticipate their needs
  • Increase security and network management assets productivity
  • Consolidate capabilities, reduce platform and application specific tools
  • Analyse machine data from systems with varying formats


  • Fraud and cyber threat detection analysis
  • Real time analysis for operational intelligence and business reporting
  • Big Data Analytics, machine data from internet/internal network
  • Monitor and ensure compliance issues
  • Monitor performance against Service Level Agreements
  • Monitor non heterogeneous networks with unpredictable formats
  • Monitor Logistics RFID and logistics databases machine data (HUMS)
  • Monitor and manage internet of things including SCADA data
  • Scientific research machine data analytics

Onboarding and offboarding

Onboarding and offboarding
Getting started Core have various plans available for training. Some training is face to face for administrators but we have extensive user based online training for our SaaS offerings. User documentation is provided where required in electronic format.
Service documentation Yes
Documentation formats PDF
End-of-contract data extraction Core provide a data extraction service for all of our customer data. 3rd party migration software will be used at an extra cost depending on where the data resides and the amount of data to offboard. Standard day rates apply for this service as per the SFIA rate card.

All data is encrypted while stored in Azure/Aurora and is securely deleted to all government standards for OFFICIAL level data upon termination of service. We can provide data extracts from any of the system run in Azure or we can off board the whole virtual machine upon request, however licensing is not transferable and the client is responsible for ensuring they are compliant with Microsoft and any 3rd party licensing for software that may be running on any system we provide as an extraction request.
End-of-contract process The off-boarding high level process is as follow:
• An authorised client representative formally notifies Core to terminate the service.
• The date and time at which access to the service will be formally agreed.
o All access to servers will cease at this time.
o All networking components / VPN connections will be halted at this time.
• All data requested to be extracted from the servers will be taken out after the access have been cut off. Data extraction fees are on a time and materials basis from the SFIA rate card.
• Once all data extracts are complete all servers for the solution will be programmatically wiped from the IaaS backend including all backups, storage and recovery vaults. This process cannot be reversed once completed and data is permanently wiped and totally unrecoverable once removed.
• Billing for the service will be calculated up to the point at which all servers and services have been wiped from the system and a final bill with usage breakdown will be issued.

Backup controls At the storage layer we keep 6 copies of the virtual machine disks available. 3 in the primary datacentre and 3 in the secondary datacentre. Replication of the disks is asynchronous so the RPO for replication is a maximum of 5 minutes for the data disks. Because we keep 6 copies live we take backups on a nightly basis which are stored in a recovery plan of 7 days, 4 weeks, 12 months, 1 year. Charging for storage based per TB.

These policies and processes also closely map to the UK Governments Cloud Security Principles.

Our framework is managed directly through the CTO's office at Core where the role of DPO also resides for any GDPR compliancy.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach Core has a robust and controlled Change Management process. Requests for change (RFC) are evaluated for the intended (and unintended) outcomes. A risk assessment is performed to understand the risk and impact to both the end user and the client entity. The risk of and the impact of failure is calculated as high, medium or low. The RFC requires three signatories (Platform operations, Platform Security and Service Operations) for the change to be implemented. Services, components, and required changes are tracked through the Service catalogue and Change processes. The service lifetime is aligned to Microsofts product, technology and service lifecycle.
Vulnerability management type Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach Core have Nessus Cloud and Microsoft System Centre Configuration Manager deployed across all servers and desktops. These products back each other up to provide up to date information on known vulnerabilities and patching requirements. We also use a variety of Microsoft licensed products (but this depends on our client purchasing and risk profiles. These include Cloud App Security, Advanced Threat Protection (Email and endpoint) and Azure Security Centre.

Patches are applied as soon as we receive an alert (so within 24 hours of information dissemination).
Protective monitoring type Supplier-defined controls
Protective monitoring approach Compromises are identified instantly through DLP and Information Protection Policies. Security Incident response is dependent on whether the client wants to purchase this from Core but typically as soon as an event is triggered or observed. This will then be followed up in accordance with contract SLAs or OLAs.
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 Core run an ITIL compliant helpdesk and incident management approach. All calls can be made directly to our 24/7 ServiceDesk function. Reports will be generated by the incident team and delivered to the client via the service delivery manager.

Separation between users

Separation between users
Virtualisation technology used to keep applications and users sharing the same infrastructure apart Yes
Who implements virtualisation Third-party
Third-party virtualisation provider Azure
How shared infrastructure is kept separate Most Microsoft business cloud services are multitenant services, meaning that your data, deployments, and virtual machines may be stored on the same physical hardware as that of other customers. Microsoft uses logical isolation to segregate storage and processing for different customers through specialized technology engineered to help ensure that your customer data is not combined with anyone else’s.
