    Checkpoint bildiğim kadarıyla israil merkezli bir firma-bunu bilmekte
    yarar var :).Bende bsd tabanlı bir FW öneririm (hurdaya çıkmış bir
    makinada bile kurulup kullanılabilir).Gerçi ideali farkı ürünlerden
    oluşan 2 katmanlı bir yapı kurmaktır ama bu derece mission critical
    verileriniz ve bunları idame ettirecek iş gücü kaynağı var mı ve buna
    değer mi düşünmek lazım.i-bekçi yeni bir ürün,özellikle kamu
    kurumlarında-emniyette vs-kullanıldığını duymuştum.Neyse IDS olarak
    da snort en yaygını diye biliyorum.
