Growing NSC Global's product business is among the priorities for popular industry figure Alex Tatham following his arrival at the network infrastructure services specialist in September 2022. The London-based Cisco, Aruba, Juniper and Dell partner's UK business endured an 11 per cent revenue contraction to £49.3m in its year to 31 October 2021 as the pandemic pinched sales. Global revenues also slid 16 per cent to £146m. NSC targets global clients in the TMT sector.
