Independent profile snapshot

This extended snapshot summarises how the provider presents itself in the UK market. It supplements the dataset-led summary above.

Abzorb Systems Ltd is a UK business telecoms and IT solutions provider headquartered at Armytage Road, Brighouse HD6 1QF, West Yorkshire, with more than 20 years' experience in the sector. The company offers an integrated channel-led portfolio covering business mobile, the Internet of Things (IoT), hosted VoIP telephony, business broadband (DSL, G.fast, FTTC, FTTP, SoGEA), Ethernet leased lines, MPLS, SD-WAN, enterprise networks, network security, alarms, access control and CCTV. Abzorb is a pioneering B2B MVNO under the "abZ" brand, enabled by Transatel (an NTT Group company and BT Wholesale's MVNO partner) since 2019, running on EE's 4G network.
