This cybersecurity supremo hailed its "significant achievement" of growing in a "difficult market", as it logged a five per cent revenue hike for its year to 31 May 2020. The LSE-listed goliath generated nearly two thirds of its £263.7m revenues from security and risk management consulting, but also saw product sales vault 69 per cent to £10.5m. The UK contributed £117m of the total, with North America and Europe/AsiaPac chipping in a further £90m and £56m.
