Fortinet secures enterprise networks and sells protection together with its own hardware, not by subscription alone.
Its distinguishing feature is custom silicon inside the firewalls: purpose-built chips process traffic faster than a general processor, which lets the company price below competitors at the same performance. Hence strong positions in mid-market and in distributed networks with hundreds of sites.
Revenue combines appliance sales with subscriptions for signature updates, filtering and support. The second part recurs and carries higher margins, so investors watch its share and the volume of contracted but not yet recognised payments.
The weak point is dependence on the hardware refresh cycle: a surge in one year becomes a collapse in the comparison the next, which has already produced sharp moves in the stock. Competition comes from Palo Alto Networks and from cloud-delivered security. The company pays no dividend.
