3COM thinks it can buy growth (expensive growth)
TPTI which makes Intrusion Prevention systems is one of the young enterants in the hot security market. SYMC, ISSX, CSCO, MFE all play in this arena. Security and enterprise markets provide few synergies to COMS. Security decisions are made by IT not by network administrators and selling to two different set of decision makers is a very tough task. Cost synergies or vendor rationalization are not great arguments to present to these decision makers.
Security products are sold through speciality security resellers where COMS has no traction currently. TPTI products sells for much higher price points then COMS products which are directed toward price conscious lower-end of the enterprise switching market. COMS has little success in building a strong channel into the enterprise market as witnessed by COMS recent miss. You can ask JNPR how tough it is to enter the enterprise security channel even with great products as JNPR has missed security revenues for last three quarters.
