TheStreet Ratings team rates VASCO DATA SEC INTL INC as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:

"We rate VASCO DATA SEC INTL INC (VDSI) a BUY. This is driven by multiple strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures, solid stock price performance, reasonable valuation levels and compelling growth in net income. We feel these strengths outweigh the fact that the company shows weak operating cash flow."
