We required very strong functional analysts to work on a high profile project; Cantarus certainly delivered. With all analysis and documentation completed to a very high standard and excellent feedback from our customers I would not hesitate to use Cantarus again in the future.

Following a bad experience with our previous provider, we met with Lee with a view to moving our website requirements to Cantarus. We knew immediately that we had made the right choice as Lee was knoweldgeable, professional and provided clear and detailed outlines of what we needed, all of which was then delivered on time and to a very high standard. We would have no hesitation in recommending Lee and Cantarus to any company looking for a reliable and professional service.

Cantarus were contracted to provide a SonicWall security and remote access solution to replace our legacy system. This was done in a very professional and timely manner, achieving all deliverables specified on the work order. Since then Cantarus have helped with other solutions in our company, building a global WAN with SonicWall appliances, and ongoing support and help. A business partner, not a reseller is how I would describe them. Looking fwd to working together with them in the future.

Axis Intermodal

Lee’s recommendation of using cloud computing for our entire business IT strategy was a bold initiative that has stood the test of time and permits staff to connect to our business systems 24/7 from any location around the world with broadband connectivity. As a result our productivity has increased, with business continuity and disaster recovery assured. Lee’s detailed technical knowledge of all aspects of cloud architecture and connectivity methodology has been essential in the business achieving and maintaining an almost fault-free environment over the many years of operations.

Cantarus' quality of service and commitment to us is outstanding and has resulted in a truly exceptional and well-supported IT solution that is the envy of our industry.

P. Hughes

Wirral Grammar School for Boys

Although we had virtualisation previously, at-least weekly we would lose connectivity, resulting in performance issues across the whole school. The solution Cantarus implemented has not only increased productivity in the school but it has resulted in less downtime and no need for maintenance.

Having partnered with Cantarus on several projects, I have no hesitation in recommending their services to any organization that wants to make solid investments in technology to increase their success.

ST*R Learning

Lee and the team at Cantarus have repeatedly gone the extra mile to help us choose the best solutions when designing and launching our websites for ST*R Learning and Worldwide Management Training Ltd. Knowledgeable, easy to talk to, and jargon-free. Brilliant service - thanks ?from all at ST*R Learning

R. Stent
Managing Director

Raffenday Limited

We have just completed a reconfiguration of several VPN links between our UK and Eastern European sites, as well as several UK home office workers to improve bandwidth and efficiency. Lee was my sole contact with this project and completed it in an efficient and friendly professional manner. I had some doubts at the start of the project that this type of configuration could be completed completely remotely. I felt that it would be necessary to be locally familiar with the client’s hardware setup and also their working practices. But Lee seemed to very easily establish a feel for the requirements and understand our needs and objectives. Based on his very professional and friendly service I have appointed Cantarus as our contracted support for all our Sonic Wall products.

N. Carter
Technical Director

Hazel Grove High School

I hired Lee and Cantarus to design a new website for our School. I cannot recommend Cantarus enough, they produced a professional looking website, which met our requirements exactly.

I. Faulkner
Deputy ICT Manager

Brett And Randall

We have used Cantarus for Sonicwall support for nearly 12 months. During this time we have moved premises which obviously had implications for our Firewall configuration. Lee was available on a Saturday to reconfigure our devices and during this time each query we had was dealt with in so much detail that Lee not only resolved our issues to complete satisfaction, but also upskilled my colleague at the same time! Cantarus truly understand not only how to configure a firewall, but more importantly the implications to technology on our business. Invaluable.

G. Worth

Very happy with our new website which Cantarus has delivered on DotNetNuke. I have had great advice and support throughout the project, and cannot wait to develop the website from this point onwards. Thank you!

J. Walker

ST*R Learning

We have been using a DotNetNuke website for several years and needed to upgrade the outdated site. I am very pleased to have chosen Cantarus to carry out the upgrade and transfer hosting to their servers. They have been easy to communicate with and have given good support throughout the process. I am now confident that ST*R Learning's website is in capable hands.

C. Thompson
Commercial Director

Design Motive

Cantarus have hosted some of our DotNetNuke websites for a few years now. They helped us get up to speed with DotNetNuke itself in the early days, especially in regard to live deployment. Their Virtual Dedicated Server hosting is great value and has been fully reliable, and their multi-level backup system recently saved our bacon! We have always found their support to be fast, responsive and helpful. One particular day was so good I felt compelled to tweet about it.

S. Holmes
New Media Manager

Gap Consulting

Absolutely delighted with our new website which Cantarus has delivered on DotNetNuke. I have had great advice and support throughout the project, and am looking forward to how the website develops from this point onwards. Now we have DotNetNuke we can provide new website features as they come onto the market. Thank you!

Stroke Association

Our old intranet was clunky and under used so we wanted to develop a new intranet to improve information sharing and joint working across our charity. Following a tendering process Cantarus won the contract to build a new DotNetNuke based intranet for us. They have been great to work with, producing clear documentation and liaising effectively with our internal project team to ensure that everyone was on board and up to speed as the project progressed.

M. Warburton
Editorial and Publications Manager

Tennants Distribution

Working with Cantarus was smooth and efficient, we conducted a weekend migration to prevent disruption to the business and the planning phase was covered so well that the implementation was straight forward. Cantarus provided us with a centrally-managed network with increased availability and flexibility through a virtually constructed environment which was exactly the technology we had been waiting for.
