Cybersecurity has something almost no other tech spending has: it doesn't get cut even in a crisis, because the cost of a breach is always higher. These are subscription businesses with very high gross margins; the classic trap is that growth is bought with so much sales spending that accounting profit takes years to appear — which is why cash matters more than the bottom line here.
This ranking sorts by fundamental quality, not by whether a stock is cheap or expensive: an excellent company can be expensive. To find the fair price, enter its quote in the analyzer. The scores recompute on their own with each new SEC filing.
