"Streamlined and reliable information management"

4/5

What do you like best about Onna?

Onna’s unified search across diverse data sources is efficient and intuitive. It integrates well with tools like Slack, Google Workspace and Microsoft 365, which saves considerable time during investigations and compliance reviews. The interface is clean and easy to navigate, even for non-technical users. Review collected by and hosted on G2.com.

What do you dislike about Onna?

The initial setup and configuration can be a bit technical without guided support. Some integrations, while helpful, require manual intervention to sync or refresh, which slows down workflows in fast-paced environments. Reporting options could also be more customisable. Review collected by and hosted on G2.com.

What problems is Onna solving and how is that benefiting you?

Onna solves the problem of fragmented data across multiple platforms by centralising information from tools like Slack, Microsoft 365, and Google Workspace into a single, searchable environment.

"An excellent tool, better service"

5/5

What do you like best about Onna?

My customer success experience at Onna has been unlike any other I've had in my professional life or, frankly, outside of work. The team at Onna is above top-of-market for their professionalism, courtesy, deep commitment to understanding my business needs and how they interact with Reveal current or upcoming product features, transparency, collaboration, stability, and friendliness. Our monthly check-in is the only call I consistently look forward to seeing on my calendar.

Onna as a product has been excellent for us. It's a really useful insurance policy for us that gives me peace of mind. I am always looking for ways to stabilize costs and make my budget contingency-proof. The Onna team is laser focused on that goal. Rather than trying to simply sell me every new feature, they have partnered with me, become an extension of my team, and only bring me product offerings that are relevant and tailored to my strategic goals. They are true partners, and I value them immensely. Review collected by and hosted on G2.com.

What do you dislike about Onna?

None that I can think of. The product has become increasingly sophisticated, customizable, and user friendly. Besides which, they have always been incredibly receptive to user feedback. So far, there's nothing I absolutely need from Onna that it can't do. Review collected by and hosted on G2.com.

What problems is Onna solving and how is that benefiting you?

Onna is a cost stabilization solution. We never anticipate - and, like most peer companies, try to avoid - litigation that proceeds into the discovery phase. At the same time, my budget contains very little margin for contingencies. I simply don't have the flexibility to absorb the massive costs that discovery could entail. This problem is especially pronounced in our Slack universe. Onna is an upfront, fixed cost that enables me to minimize contingency-based variance in my legal spend. For me, having stable legal costs is more important than keeping them low but subject to massive change. Onna enables me to do that, and their team is laser-focused on helping find more ways to achieve that goal for me. Review collected by and hosted on G2.com.

Review collected by and hosted on G2.com.

What do you dislike about Onna?

While Onna excels in many areas, there are a couple of aspects that could be enhanced for an even more robust experience. Firstly, the platform could benefit from improved central management and distribution of authentication tokens among custodians. Implementing a more sophisticated custodian authentication management system would streamline access control and permissions management, particularly in complex scenarios involving multiple custodians or large data sets.

Additionally, enhancing API flexibility is another area where Onna could see improvement. Greater flexibility in working with APIs, including the provision of additional pipelines and customization options, would significantly elevate the user experience. Allowing users to create their own DIY connector modules, akin to BrowserFlow, would be a particularly valuable addition. Such a feature would enable users to tailor the platform more precisely to their specific data sources and requirements, offering enhanced adaptability and efficiency in data integration and management.

Together, these enhancements in custodian authentication management and API flexibility would significantly augment Onna's capabilities, making it an even more powerful tool for data integration and management in various professional contexts. Review collected by and hosted on G2.com.

What problems is Onna solving and how is that benefiting you?

This comprehensive data aggregation is particularly beneficial in ensuring no critical information is overlooked during eDiscovery processes. Additionally, Onna's centralized approach to data management has greatly assisted in maintaining clearer oversight of our digital data landscape, which is vital for effective digital forensic analysis and reporting.
