Onboarding and offboarding

Getting started
There are several stages to the on boarding process. Technical: the systems that generate data must be configured to send their data to a central collection point on the customer's site, and then forwarded over a VPN to the service. Service: relevant SLAs must be agreed, as well as the RPOs and RTOs for the data. People: we can arrange Splunk training for staff in accordance with the customer's need. In addition, on site training around access to the service, over and above Splunk-specific training, can be given.
Service documentation
Documentation formats
End-of-contract data extraction
We can work with clients to determine the best option. Either as a compressed file in a secure location within the service, or on physical, encrypted media. The data will be in either: csv, json, raw, tsv or xml format, depending on client requirements.
End-of-contract process
Any hardware implemented on client sites must be returned within 30 days of contract end. Any data held within the client environment will be scrubbed and wiped as part of the environment decommissioning process. However, as the entire infrastructure is virtual, there will not be any hardware disposal implications.

Independence of resources
The infrastructure is based on Amazon AWS and is monitored for usage. Where loads exceed thresholds, individual clusters can be resized, meaning that we can respond to increased load through increases in compute resource.

Approach to resilience
We use Amazon AWS London region and deploy resilient architecture in to multiple availability zones. More information on AWS resilience can be found here:
Outage reporting
We report outages by email. For significant outages we will contact the client by phone.

Identity and authentication

User authentication needed
User authentication
  • 2-factor authentication
  • Limited access network (for example PSN)
  • Dedicated link (for example VPN)
  • Username or password
Access restrictions in management interfaces and support channels
All access to the service by the client is over a dedicated VPN from their own infrastructure; access is not possible between clients via this route due to internal routing controls. Access is possible by Axcelot staff, but is limited to using bastion hosts as proxies that are not directly accessible. Axcelot has undergone an IT Health Check for our own management infrastructure.
Access restriction testing frequency
At least every 6 months
Management access authentication
  • 2-factor authentication
  • Dedicated link (for example VPN)
  • Username or password

We undergo external audits on a 6 monthly basis to ensure compliance.

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
We use a Configuration Management Database (CMDB), integrated with our Change Management and Service Desk systems to track the asset lifecycle. All changes are reviewed at a weekly Change Management meeting, where risks are assess and previous changes reviewed. Emergency changes may be implemented only with the approval of a member of the board.
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
We use Tenable Nessus to scan our infrastructure on a weekly basis for vulnerabilities. Patches are deployed within seven days of release, unless a risk assessment highlights a need to postpone changes. We maintain contacts with special interest groups and subscribe to multiple threat lists, including those for all of the operating systems, applications and appliances we use.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Axcelot runs a 24x7 Cyber Security Operations Centre (SOC), which monitors all aspects of the service, as well as systems from other clients, using Splunk Enterprise Security. Incident response is undertaken by the SOC using playbooks for particular scenarios. If we were to suffer a client-impacting breach we would immediately inform the client, with details of what happened and an assessment of the client data compromised. We would then work in partnership with the client to mitigate the effects of the breach.
Incident management type
Supplier-defined controls
Incident management approach
There are a number of pre-defined processes that cover the majority of common breaches. These may be invoked either through our own monitoring of the service, or as a result of a client contacting the Axcelot Service Desk. Incident reports would be available upon request.
