InterQuest Group

Overview: Major recruitment firm, InterQuest Group was experiencing network issues across its sites and latency issues. Solution from Exponential-e reduced infrastructure costs whilst increasing speed and improving scalability.

Sector: Professional Services, Recruitment.

Solution: Eight site Wide Area Network.

InterQuest Group (InterQuest) is a market-leading IT and Analytics recruitment firm, which comprises a number of specialised recruitment units that operate specifically in one market segment, be it in the public sector, banking and finance, or in an area of technology such as testing, analytics or CRM. The Group operates from its head office in London and several branch offices. Specialising in contract and permanent IT recruitment, the Group trades as several distinctly branded, operating divisions.


InterQuest was experiencing several issues with its existing network service. It had previously moved to a DSL based MPLS network, but still faced issues with inconsistent speeds. The service was proving to be unreliable and the company repeatedly faced prolonged downtime affecting business operations for days at a time.

Due to continued business success, InterQuest had grown to become a multi-site operation over the years; each specialist recruitment division operated as an individual business unit whilst some services within these were centralised. Many sites however, had started to experience performance issues and latency, and as a result they were becoming increasingly dependent on InterQuest’s London head office.

The company was also finding its existing provider was unable to respond to its needs in fast time frames and connectivity was often lost, hence affecting inbound and outbound business communication. InterQuest had reached a point where its old network service was not reliable or fast enough to keep up with the demands and growth of the business.

The Group started searching for a new solution which was able to provide improved service levels, increased speed and cost savings on routing voice calls internally. With a view to plan long-term, InterQuest also sought a scalable platform which could grow with its business requirements.


A number of established and well-known suppliers within the market were considered for project delivery. InterQuest selected Exponential-e based on its technical expertise, receptive approach and value.

Exponential-e worked closely with InterQuest to deploy an eight site Wide Area Network (WAN), which extended between Yorkshire and Kent, as well as centralised Internet, security and backup solutions. Exponential-e began work with a redesign of InterQuest’s existing infrastructure. The first phase of the network roll-out started with the various locations being brought on-net to Exponential-e’s switched core Next Generation Network (NGN) for improved resilience.

The following phase saw Exponential-e provisioning virtual circuits over the access circuits required, allowing Exponential-e to establish full connectivity between all InterQuest office locations. By centralising the Internet connection in Exponential-e’s facility, the Group’s branch offices are no longer reliant on the head office for Internet connectivity, allowing for a more agile and flexible set-up.

In addition, Exponential-e configured a dedicated VPLS instance for InterQuest, providing a completely secure WAN. Exponential-e provided a Private DSL connection from the site through a new Virtual LNS instance into the existing InterQuest VPLS WAN. The new solution allows InterQuest to route voice over its internal network and save costs.


Since the new network was deployed InterQuest has benefited from greater reliability and vastly improved high-speed connectivity at a reduced cost. Low maintenance is also providing savings on the company’s operational costs, allowing InterQuest to focus on the running of its core business. The Layer 2 network allows for the use of Open Shortest Path First (OSPF), which gives the Group the flexibility to add new offices or change the existing configuration whenever needed. The organisation now has a scalable platform which will grow with the business.
