Qruse Internet
Qruse Ltd is a 100% independent, unbiased provider of internet services. Due to our impartiality, it gives us the benefit or the edge on choosing the right product for clients’ specific needs. The problem with dealing directly with an ISP is that they will only ever push or recommend a product or service that they supply which in many cases is not necessarily the right product. The client not only receives the best impartial advice, but also receives an additional layer of support over and above the support offered by the company that we place the business with. The ISPs that we partner with must offer a comprehensive SLA with in excess of 99.975% availability.
