Cybersecurity giant Darktrace has appointed former BT CEO Sir Peter Bonfield CBE to its board ahead of a potential £4 billion stock market flotation. 

Darktrace’s self-learning security technology defends more than 4,500 organisations worldwide by autonomously detecting, investigating and responding to threats from insiders, remote working, ransomware, data loss and supply chain vulnerabilities. 

The Cambridge-headquartered company, which has 1,500 employees and 44 office locations, has also dropped co-CEO Nicole Eagan, who is based in the US, to the position of head of strategy, with Poppy Gustafsson now its sole chief executive ahead of the planned float, which it hopes will raise £4bn.
