Terry Smith (pictured), is the manager of the £22.3bn Fundsmith Equity fund.
Fortinet is a California-based developer of security solutions, including firewalls, endpoint security and intrusion detection systems, with a market capitalisation of $45.2bn, according to Morningstar Direct.
On Thursday (2 November), the firm's shares fell almost 20% in what Morningstar analyst Malik Ahmed Khan described as a «knee-jerk reaction» to its financial results, which revealed that the company had come short with its fourth-quarter revenue forecast.
