"Great tool for common data sources"
4/5

"Excellent aggregation of Slack GRID"
5/5
What do you like best about Onna?

We have a massive amount of workspaces and Onna makes it easy to quickly and efficiently search for people/messages/files across every single one of them. The ease and the efficiency of searching makes Onna great for our uses. Review collected by and hosted on G2.com.

What do you dislike about Onna?

Sometimes when exporting search results, especially more considerable amounts of results, the export will hang, giving very little clue as to why. It also often takes several hours to get notified that the export failed. It would also be super helpful if there was a way to text-query with the advanced search feature instead of the query-builder. Review collected by and hosted on G2.com.

"Onna makes legal holds easy."
4/5
What do you like best about Onna?

Onna makes it easy to put legal holds in place in regards to our Slack instance. The customer success team is knowledgable and is always looking for ways for us to get the most value out of our plan. There are more tools besides Slack that are available to bring into Onna as well. Review collected by and hosted on G2.com.

What do you dislike about Onna?

Some aspects of the admin dashboard are not easy to navigate, and it took more time than it should have to set up the permissions/connections with Slack. Sometimes trying to get to the window we needed to perform an action wasn't clear. Review collected by and hosted on G2.com.

"Discovery use review."
3.5/5
What do you like best about Onna?

The customer service and the people. I like being able to provide feedback on new services. However, there should be a steep discount for the time given on rolling these out, but instead, our support time response was rolled back, and the price went up. Review collected by and hosted on G2.com.

What do you dislike about Onna?

The integrations should have a higher security standard. Once the connections are in place - the data pulled should be more inclusive, especially when it comes to JIRA tickets. Salesforce data pull should also be able to draw more than just the essential data. Workspaces, preservations and in-place preservations - these options are confusing, and the differences should be laid out more clearly. Review collected by and hosted on G2.com.

"Some good, some not so good."
3.5/5
What do you like best about Onna?

The platform is very user-friendly and easy to use. If you are looking to run searches on emails, this is a very helpful tool. The customer service folks are also very helpful and nice. Review collected by and hosted on G2.com.

What do you dislike about Onna?

The time for Google products to sync into Onna is painfully long. It is hard to explain to outside counsel that we need multiple weeks to sync data before we can even start to run searches, export to a traditional ediscovery vendor, etc. Review collected by and hosted on G2.com.

Responses times from Onna support is sometimes a little laggy, and the training section could use a little more content...but it's been getting better. Review collected by and hosted on G2.com.

"Great, support and partnership team have been engaging and answered our needs"
4/5
What do you like best about Onna?

the number of data sources that is support and the fact that custom metadata is also preserved as part of that collection exercise. Coupled with the ability to target collections and filter prior to syncing. The proactive sync is also something unique against the other tools we have. Review collected by and hosted on G2.com.

What do you dislike about Onna?

the search and overall layout of the results. It is something hard to get a clear picture of data when you want to focus on one custodian or a channel. Maybe a file tree or filterable table view that shows more Review collected by and hosted on G2.com.
