Cramer has spoken to both companies' management teams on his "Mad Money" TV show and he enjoys the discussions because the industry is continually changing so much.
Proofpoint is an email protector, while FireEye is more of a post-hacking investigator, although it's working on adding different services as well. However, it appears that Goldman Sachs analysts now view the latter more favorably than the former.
While Goldman may believe that FireEye is a buy, Cramer is not necessarily on board. Sure, it could be a takeover target or even rally to the $15 to $16 range without issue.
But betting on a cybersecurity company is a bet against Cisco (CSCO) , and seeing what Cisco has done to Palo Alto Networks (PANW) makes that bet a concern. CEO Chuck Robbins has made cybersecurity a very big priority at Cisco and that could be bad news for its competitors, Cramer concluded.
