Both are real risks. But supply chain attacks exist whether you self-host or not... you're still running the vendor's code either way. The question is whether you also want that code to stay up to date and properly managed, or drift silently.

I agree that keeping things up to date is a good practice, and it would be nice if enterprise CISOs would get on board with that. One challenge we've seen is that other aspects of the business don't want things to be updated automatically, in the same way a fully-managed SaaS would be. This is especially true if the product sits in a revenue generation stream. We deal with "customer XYZ is going to update to version 23 next Tuesday at 6pm eastern" all the time.

This is true even with fully-managed SaaS though. There are always users who don't want the new UI, the changed workflow, the moved button. But the update mechanism isn't really the problem IMO, feature flags and gradual rollouts solve this much better than version pinning

[nickmonad]

Sure. I'm just saying in the context where fully-managed SaaS was already decided not to be an option, and a customer is deploying vendor code in their environments, the update mechanism can in fact be a problem. It's not just poor CISO management.
