Ironport and openDNS are not doing better. Sourcefire is mediocre and I don't know about the rest. I hope you read this,the reason why Cisco chooses to aquire rather than compete is the same reason those companies would do better without Cisco. I am glad for the founders who get aquired but at least the John Chambers era aquisitions did not fare well.
