Cloud Ops Lead at a tech vendor with 10,001+ employees
Cloud audits have become smoother and data risks are reduced through automated discovery
I cannot think of any improvements, really. Sentra does what it's meant to do, finding shadow data. If the data classification feature was improved ever so slightly, maybe a little bit quicker to use, that would be good, but that's the type of thing where it's never going to be perfect anyway, so there are no real improvements that I can see with Sentra, no big ones anyway. The only area where I see potential for improvement is making it quicker to use the data classification section. Other than that, I haven't seen any areas where I'd want it to be improved.

What is your primary use case for Sentra?
My main use case for Sentra is agentless data discovery. Sentra offers the ability to identify across the entire cloud estate data which is in the wrong environments, sensitive data which is unencr...
What advice do you have for others considering Sentra?
I would say that audits could be anywhere from 10 to 20% smoother from using a tool such as this, because if data is classified properly and you're able to prove that very clearly, and also data is...
