When Microsoft Exchange servers were hacked a few days ago, people on hacker news were talking about how most companies are not capable of securing their own on-premise systems and they should have used Office 365. There really isn't a perfect solution. There are trade-offs.
- ocdtrekkie 6y agoIt's a lot easier to secure on-premise Exchange than Office 365. For one, having OWA exposed to the Internet is entirely optional for Exchange on-prem... but impossible for avoid for a cloud service. Most possible ways to secure access to Exchange on-prem are built into your firewall, and you can configure at leisure... most possible ways to secure access to Office 365 are billable add-ons to your subscription. Any side channels to that... you just have to trust Microsoft... I agree there are trade-offs, but especially for large enterprises with security teams, on-prem is definitely more secure.
