A technology startup founded by a former employee of British spy agency GCHQ has raised $8m (£6.2m) in investment from Goldman Sachs and other investors.

Immersive Labs, which is headquartered in Bristol, runs online training sessions for people to learn about cybersecurity in order to help companies defend themselves against hackers.

Chief executive James Hadley is a former security researcher and instructor at GCHQ, but founded Immersive Labs in 2017 to teach technical skills in the private sector.

The company has since brought in clients including BAE Systems, Sophos and Grant Thornton.

Immersive Labs has hired cybersecurity expert Max Vetter, a former covert internet investigator who worked in Scotland Yard's money laundering unit, as its chief cyber officer.

Former GCHQ director Robert Hannigan advises Immersive Labs, and spoke at an event hosted by the business in November.

Mr Hannigan said that Mr Hadley had tried using his approach to teaching cybersecurity skills that forms Immersive Labs whilst he worked at GCHQ.
