What: Shares of Check Point Software (Nasdaq: CHKP) have plunged today by as much as 12% after the company reported earnings.

So what: Both revenue and earnings in the first quarter came in slightly ahead of the Street's expectations, with $313.1 million in sales and a profit of $0.74 per share. The real kicker was in guidance for the coming quarter, which left investors wanting more.
