Dovetail is awesome, particularly if you have large volumes of research you need to run analysis on. They've been working at it for a while and finely tuned their repository product.
We're focused heavily on the other end - the research ops part you mention and while we have a way to go I'd like to think we've nailed the use cases you mention. We have some analysis tools, and we're investing here but it's a big problem category.
PII and data security are front and center in our product values, with SSO on our roadmap; really looking for that first customer who needs it to have this prioritized.
