FTNT data by YCharts.

Fortinet reported fourth-quarter earnings at the very start of last month, and it was a smashing success story. Both top-line sales and bottom-line earnings came in far ahead of analyst expectations, followed by a strong set of next-quarter and full-year guidance targets. Shares rose 13% overnight on the news, as investors were inspired by a classic beat-and-raise report.

Now what

Fortinet's strength is a wide-ranging product portfolio that covers security aspects of everything from the smartwatch on your wrist to the data center big-iron server that analyzes the fitness data your watch sends in -- and every point of the networks in between. The company calls it a security fabric, which offers stronger data protection than plugging in separate security tools for devices, networks, and servers.

Investors can look back at market-beating returns of 22% so far in 2017, or 29% over the last 52 weeks.

Fortinet is a quality business in a leadership position of a timely market, and it's often worth paying a premium for that combination.
