Cybersecurity companies provide services to protect electronic information from theft or damage. Businesses in the cybersecurity industry utilize both software and hardware to ensure that computing devices and data are not misused. The industry serves a broad array of customers including individuals, businesses, and government, among others. Some of the leading names in cybersecurity include Check Point Software Technologies Ltd. (CHKP) and NortonLifeLock Inc. (NLOK).

Cybersecurity stocks, represented by the First Trust NASDAQ Cybersecurity ETF (CIBR), have outperformed the broader market over the last year. CIBR has provided a total return of 49.4% compared to the benchmark iShares Russell 1000 ETF’s (IWB) total return of 35.7% over the past 12 months. These market performance figures and all statistics in the tables below are as of Sept. 9, 2021.

Here are the top 3 cybersecurity stocks with the best value, the fastest growth, and the most momentum. Note that the companies on our list are primarily pure-play cybersecurity companies, while CIBR includes a wider variety of related stocks in its portfolio.

These are the cybersecurity stocks with the lowest 12-month trailing price-to-earnings (P/E) ratio. Because profits can be returned to shareholders in the form of dividends and buybacks, a low P/E ratio shows you’re paying less for each dollar of profit generated.

These are the top cybersecurity stocks as ranked by a growth model that scores companies based on a 50/50 weighting of their most recent quarterly YOY percentage revenue growth and their most recent quarterly YOY earnings-per-share (EPS) growth. Both sales and earnings are critical factors in the success of a company. Therefore ranking companies by only one growth metric makes a ranking susceptible to the accounting anomalies of that quarter (such as changes in tax law or restructuring costs) that may make one or the other figure unrepresentative of the business in general. Companies with quarterly EPS or revenue growth of over 2,500% were excluded as outliers.
