It would be beneficial if these interactions could be more plug-and-play and less code-intensive, making them more efficient and easier to set up.

Setup Cost

Ataccama ONE Platform pricing is reasonable, with additional fees for features, impacting organizations with specific data security needs.

Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.

What made the costing a problem with Ataccama ONE Platform is related to licensing, as it is every one year.

Dm-Dm

data engineer at a tech vendor with 10,001+ employees

The only concern I had was that some features like address validation cost a little extra with the basic plan.

Akhil Danturti

Valuable Features

Ataccama ONE Platform excels in user-friendly data management, offering automation, scalability, and AI features for enhanced governance.

Microsoft Purview eDiscovery ensures efficient data retrieval with multi-platform integration, automation, compliance visibility, and adherence to global data privacy laws.

We were able to interface bidirectionally with Collibra for data governance, catching data quality issues before propagating through the system.

JohnZacharkan

Senior Architect at SourcEdge

It is very good in scalability.

reviewer2788908

Data Engineer lV at a consultancy with 11-50 employees

Ataccama ONE Platform has positively impacted our organization because before its implementation, completing tasks such as more than 100 or thousands of rules took more than a week. Now, we complete those tasks in less than two or three days due to the automation and one-time task capability.

reviewer2790621

Featured Reviews

Akhil Danturti

Data Governance Analyst at Entain India

Streamlines reusable data quality rules and has highlighted the need for richer logic and documentation

I worked in Ataccama ONE Platform from version 5 and now we have version 15, which has improved a lot. However, there is still considerable scope for improvement because Ataccama ONE Platform was not that great around 2020 when I started working with it. There can still be more features including writing any logic, improving more keywords for logic building, and enhancing address validation, based on my understanding. User experience is actually good; I do not have any complaints or feedback on that. However, the documentation part can be improved because documentation is key for any organization or tool. If anything is needed for understanding, you have to rely on documentation. Ataccama's documentation has potential for improvement.

Frank Radeck

Director, IT Infrastructure & Cloud Technology at a legal firm with 501-1,000 employees

Tasks that took an entire day before we implemented the solution now take just 30 minutes.

The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.
