Cisilion has become the first Cisco Premier Select partner to win a Silver accreditation from the vendor this year.
Cisco recently withdrew the Premier Select classification, returning its Premier Select resellers to Premier Partner status.
Cisilion joins only nine firms in the UK to hold the Silver award, Cisco's second highest certification. The others include Siemens Communications, Mitech, Morse Group and EDS.
Chris Jenkins, product and marketing director at Cisilion, said: "We have been around for just over three years, and our direction has always been aimed at Cisco and trying to double our revenues year on year."
John Donovan, UK and Eire channel manager at Cisco, said: "Cisilion has made tremendous progress, showing expertise in IP telephony, network management, wireless LANs and virtual private network security, and has achieved a measurable level of customer satisfaction."
