The firm said some of the large resellers are yet to fully engage with Proofpoint, which it sees both as a challenge and an upside potential. Given that the company has less than 20 percent market share, the firm sees plenty of opportunity for it.

Along with the downgrade, the firm also lowered its price target for the shares to $77 from $92.
