My 2 cents : I would suggest that you look at NBAD(network based anomaly detection) devices like Arbor networks in combination with something like Fireeye. Combined, they can help in identifying and blocking bots & malware. Placement of these devices properly, can help you control your network.

If you are talking about a classic company network and dividing workstations into separate networks to prevent cross contamination, you have to consider the pivot points for most malware - email, file shares, etc, which can still allow malware to propagate between networks even if no traffic is allowed directly between them. Some kinds of malware, notably worms who propagate directly from one system to another via some kind of remotely exploitable vulnerability, would be contained by network segmentation, however those sorts of events are becoming increasingly rare (however when they do happen, they tend to be big events).
