Overall, we manage to get a 'bullet-proof' patch in about 4-5 weeks (from coding->QA->Build/Packaging->shipment), which I consider not so bad. But the other day, we got an urgent request from our support team to come up with a decent fix in 48 hours. I think they're a tiny bit unrealistic. So I wanted to get feedback from my peers: are we doing that bad? It takes months for other software vendors to issue zero-day exploit fixes, are our customers being unreasonable?"
