Support response times We offer four priority support levels (P1, P2, P3 & P4). Priority One is assigned to system down or significant-loss-of-business events, with a response time of up to 1 hour and 4-hour fix time. Priority Two issues carry a response time of up to 4 hours and a fix target of 2 business days. Under the standard support agreement, Netcel’s support desk is manned 8am-6pm UK time, Monday-Friday, excluding public holidays. We can potentially offer a 24/7 support service.
User can manage status and priority of support tickets Yes
Online ticketing support accessibility None or don’t know
Phone support Yes
Phone support availability 24 hours, 7 days a week
Web chat support No
Onsite support Yes, at extra cost
Support levels Within our two main services – Priority Support & Continuous Improvement – we have 5 different support levels. Priority Support covers Priority One and Two defects defined as; Priority One - Response is up to 1 hour (catastrophic & functional critical); Priority Two - Response is up to 4 hours (functional critical). Priority One or Two levels are dealt with as a matter of urgency based on the SLA response and fix times. Typically, these are deployed as hot fixes due to the nature of the issues, hence the name ‘Priority Support’. Defects that fall outside of Priority Support definitions are delivered via the Continuous Improvement programme, i.e. Priority Three, Four and Maintenance issues. Where there isn’t an immediate need to resolve the issue, greater efficiencies can be leveraged by combining tickets into regular deployment windows (typically monthly) in a Continuous Improvement programme. This is a managed process with the involvement of a BA / PM to identify and review the requirements for the next release. A member of the support triage team is responsible for resolution of each support ticket.

Independence of resources Through differing levels of performance, load and stress testing we ensure that the service itself is resilient to high loads. Both the applications we architect and deliver and the infrastructure upon which they reside are built appropriately for the anticipated load and, within reason, and more. Our services are designed to scale appropriately.

The net output of the architecture, implementation and infrastructure we deliver is a service where high traffic will not affect other users of the service.

Data importing and exporting

Data importing and exporting
Data export approach Clients can export data from their CMS solution directly to ODF, CSV, Excel or alternatively directly to a similar CMS. This is particularly helpful when working across several environments that sit across the same infrastructure. This function is widely used by developers building new functionality in a test or development environment. When work is completed, and the information is ready for the production environment, you can simply use the export features to transfer the data between websites.

Availability and resilience

Availability and resilience
Guaranteed availability For a period of 12 months from acceptance, the service will be free of viruses, trojan horses, logic bombs and other deleterious materials except where any such materials have been introduced to the service by the Client or any third party appointed by the Client; and

It shall use all reasonable skill and care in the provision of the Project to the Client, using at all times appropriately qualified and skilled personnel in the delivery thereof; and will not infringe the intellectual Property Rights of any third party.
Approach to resilience All infrastructure provided to our clients has the option for complete resilience either within a single datacentre, across multiple datacentres in a single region (such as the UK) or across multiple datacentres geographically.

This configuration allows for the worst case loss of an entire physical datacentre with services remaining fully operational.

Methods such as load balancing, mirroring and the more traditional failover are utilised to provide such resilience.
Outage reporting Outages can be reported via different channels subject to the specific requirements either in real-time or delayed until the next working business day.

Our services can provide access for service outages to a private, client specific, dashboard. Email alerts can also be provided alongside a more personal phone call should a service outage occur.

We are also able to hook in to different channels such as API alerts should these be required.

Outages for maintenance include: Emergency maintenance - we aim to notify you of this outage as soon as practicably possible. Planned maintenance - we shall use reasonable endeavors to provide you with a minimum of seven days’ notice and shall in any event give you as much notice as practicably possible. Scheduled maintenance - our standard scheduled maintenance window is every day between 12am-3am UK time. In this case, we shall, where practical, provide notice of such. All clients will be notified via email, phone and dashboard as appropriate.

Security governance approach Monitoring is deployed within our network to audit access to data both as the individual and the device. Our network contains both application security and threat analytics via industry standard monitoring solutions helping to enforce our policies.
Information security policies and processes Netcel follow a standard information security policy in context of modern cyber security classified as "a formal set of rules by which those people who are given access to company technology and information assets must abide."

Our policy covers hardware, software, communications and data throughout. Information is classified in to categories based on the confidentiality of the data.

Monitoring is deployed within our network to audit access to data both as the individual and the device. Our network contains both application security and threat analytics via industry standard monitoring solutions helping to enforce our policies.

Violation, either automatically detected or manually detected, must be reported to the IT department immediately from where the issue will be escalated accordingly.

Any security vulnerabilities identified by third parties are addressed in accordance with the industry standard recommendations as a priority.

Where possible, environment configurations are fully automated and controlled with all configuration and change operated through auditable source control.
Vulnerability management type Supplier-defined controls
Vulnerability management approach In accordance with our cyber security policy, access to our networks is monitored through automated solutions to detect, as close to the perimeter as possible, any initial threat.

Infrastructure, both internal and that which we provide as part of a service, is patched at least on a monthly cycle in accordance with Microsoft best practice recommendations.

Information regarding potential threats is obtained from our automated solutions and specialist security partners.
Protective monitoring type Supplier-defined controls
Protective monitoring approach In accordance with our cyber security policy, access to our networks is monitored through automated solutions to detect, as close to the perimeter as possible, any initial threat.

If a potential compromise is detected this is addressed through the security software that we have deployed either blocking the compromise automatically or manually.

Where a potential compromise is being attempted automated escalation of security risks are undertaken and approaches such as multi-factor authentication are instigated to protect the network and data within.

Responses to incidents are on a priority basis and attended to immediately where feasible.
Incident management type Supplier-defined controls
Incident management approach Users are, subject to the specific incident type, generally required to escalate incidents to the IT department upon discovery from where the incident will be triaged and further escalated accordingly.
