Onboarding and offboarding

Onboarding and offboarding
Getting started Once a call-off contract has been agreed, we will undertake all the work to provision the cloud hosting service within 48 hours. The key users will be given access to the services and to Helpdesk (ticketing), Zenhub (knowledge base) and Forum.

Training can be agreed on the basis of individual client's requirements.
Service documentation No
End-of-contract data extraction Data extract methods would depend on what the user had put onto the servers. The most likely option is a straightforward back-up. If you do not have the resources to do this, we can undertake it as an extra cost option.
End-of-contract process Full support in line with the SLA will continue up to the end of the contract. Any work you ask us to do after you have ceased paying for the infrastructure would be charged at our normal day rate (of £800 remote, £950 onsite).

Using the service

Using the service
Web browser interface Yes
Using the web interface Users can provision, delete and configure environments.
Web interface accessibility standard WCAG 2.1 AA or EN 301 549
Web interface accessibility testing We regularly test screens from the UI using VoiceOver. Users with partial sight have actively used Contensis in a work context on a number of occasions. The system also has icons and other visual cues throughout, rather than relying on text. Our testing suggests that people with dyslexia would be able to use the vast majority of the system from the beginning, and would learn to recognise the very few text-rich screens and features after only a short period of familiarisation.
What users can and can't do using the API Users can create instances and delete instances.
API automation tools Ansible
API documentation Yes
API documentation formats HTML
Command line interface No

Availability and resilience

Availability and resilience
Guaranteed availability Our services have an uptime of 99.99%, measured on a monthly basis. This includes planned maintenance.

Service credits are calculated on the basis of the difference between actual and SLA availability:

service credits = (100 - a) x b
a = the actual percentage availability of the infrastructure during the relevant calendar month; and
b = the Charges payable in respect of access to the infrastructure during the relevant calendar month (exclusive of VAT and other taxes).
Approach to resilience The service operates from multiple Tier-3 datacentres in separate geographical regions.
Each datacentre has separate electricity substations. Dual power cables run to each item of equipment. There are also back-up generators.
All infrastructure is virtualised. An individual logical server, e.g. a CMS server, has an average of 3 physical servers underlying it.
All equipment is monitored, and can be host swapped and remotely managed.
All key services are duplicated, including firewalls, routers and internet connections.
Outage reporting Since we meet or exceed the 99.99% uptime, outages of the Contensis cloud service are rare. If they do occur, they typically involve a single client.

Issues raised by the client will be via the Helpdesk, so all client staff with access will be aware of it and can follow progress to resolution. If we become aware of the outage outside the client's normal working hours, we will pro-actively raise a ticket on your behalf, and if appropriate, report the issue by email.

We can also phone if you have provided an out-of-hours contact. We will engage with your incident management process where appropriate.

If an issue affected multiple clients, we will issue a group email explaining what occurred, what action we have taken to resolve it and how we plan to prevent it in future.

Identity and authentication

Identity and authentication
User authentication
  • Identity federation with existing provider (for example Google apps)
  • Dedicated link (for example VPN)
  • Username or password
Access restrictions in management interfaces and support channels Anyone wanting to self-register on the Helpdesk or Cloud Dashboard requires a valid client email address. Once registered, it can only be accessed by registered users who authenticate.
Access restriction testing frequency At least every 6 months
Management access authentication Dedicated link (for example VPN)

Security governance

Security governance
Named board-level person responsible for service security Yes
Security governance certified Yes
Security governance standards ISO/IEC 27001
Information security policies and processes All staff receive a set of standard training sessions at the point they are recruited, and this includes secure work practices. These are reinforced through ongoing appraisal and supervision processes and are included in the Staff Handbook.

As an ISO 27001 registered company, our data handling process is scrutinised on a regular basis as part of internal and external quality audits.

As a company we are registered with the Data Protection Registrar.

Where an issue requires escalation, we have a set of identified processes, including phone numbers, so that you can talk directly and express the level of urgency or business challenge. The levels are:-
After 1 hour Head of Support
After 2 hours Chief Product Officer
3 hours+ Chief Executive Officer
One of the key advantages of working with Zengenti Ltd, is that we keep the barriers to communication as low as possible - commensurate with delivering services efficiently to our whole client base. This means that when you need to speak to someone with the necessary technical skill and the authority to decide a course of action, you can.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach Our infrastructure is managed through a configuration management system. As a result, all changes to configuration of customer environments is auditable. Changes are first tested in staging environments, before being rolled into production.
Vulnerability management type Supplier-defined controls
Vulnerability management approach We assess potential threats through proactive monitoring of logs and security advisories from major partners/suppliers in the security sector.

We can deploy patches in minutes, but we would assess the risk posed by the particular vulnerability and decide the most appropriate schedule. Typically patches are applied monthly.

We recently had an opportunity to prove the resilience of our processes, when our engineers discovered a vulnerability. Within 48 hours, we had put fixes in place to eliminate any potential risk and told all our clients about the process. We also upgraded all our hosted clients.
Protective monitoring type Supplier-defined controls
Protective monitoring approach We have monitoring systems in place that will detect unexpected network traffic and behaviour on servers. There are a range of different solutions depending on the device, for example, on a Linux server we will be automatically notified if there's a change in user account details.

If we find a potential compromise, our incident management process would be triggered.

From that point, the speed of response would be agreed between the engineers and the incident manager.
Incident management type Supplier-defined controls
Incident management approach The majority of incidents are handled through the helpdesk. This streamlines incident management, tracking and resolution. Supportive questions help us gather essential information. Users rate the severity via impact on their business processes.

For critical incidents, on-duty incident managers assess the situation and any affected customer(s), and create a communication list for the incident.

They will:
● instigate conference calls
● a high-level view of problems
● ensure resolution of the issue within SLA
● be involved in the debrief
● provide incident reports on resolution

All communication are available within the service desk portal.

Energy efficiency

Energy efficiency
Energy-efficient datacentres Yes
Description of energy efficient datacentres Our colocation partners are committed to constantly monitoring and where practical reducing energy use. The London DC (Interxion), which operates entirely on renewable energy, is typical. Their summary is "Core to our operational ethic is continual management of our use of energy, measured through Power Usage Effectiveness (PUE), which measures how efficiently a data centre uses energy. As an active member of industry groups focused on Green IT and energy efficiency, we strive to maximise use and support of sustainable energy sources across our European footprint."
