Helps with GDPR compliance through data discovery and management
We knew that we have a lot of scanned docs inside our repositories, but there was a big issue where we needed to know which content was really an image. Because of the OCR made at runtime during the scan, now we know exactly the data we have. When you have zipped documents the scan will unzip them and find the data inside.

Easy to categorize documents and offers transparent view of documents
I found Relativity very useful because it's easy to categorize documents. If you get more complex litigation, like around 500,000 or 1,000,000 documents, it's easier to categorize them in Relativity. So, it's a more powerful tool for reviewing documents. I haven't faced any problems using Relativity yet. I found it very useful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"In terms of ROI a company will, in a short time, recover from the initial investment, because the product, other than allowing a company to be GDPR compliant, will give a lot of information on how the storage is used and this will guide the IT to better usage of this resource."
"IBM StoredIQ Suite helps to address problems like data discovery, records management, compliance activities, storage optimization, and data migration initiatives."
"Caplets are a very good technical feature."
"The most valuable feature from my perspective are the Kepler; it's a component that is more technical and directly related to the development companies that will be using it, allowing you to create custom APIs and gather most of the information that is not available in the standard API that they offer."
"The solution has great searching capabilities, and it's very reliable."
"kCura Relativity is easy to use, and it is reliable."
"The searching capability of the product is definitely very valuable to our organization."
"Unquestionably, kCura Relativity is a scalable solution."
"It is easy for a beginner to learn to use Relativity."
"The ease of navigation from dock to dock, and that kind of usability, is quite helpful."
 

Cons

"The product was born and designed to be used inside the IT department, but it would be improved by allowing end-users to search for info related to specific needs."
"I would definitely not recommended it unless you have someone who has had experience with it and knows how to work the program."
"They require more built-in support for some third-party applications."
"There are a lot of bugs on the development side."
"You are charged per user. It can get pretty expensive if you have a lot of users in your organization."
"I think RelativityOne, because it is so powerful, can be very difficult to use and there's a lot that can go wrong if you don't know how to use it."
"I think there is a lot of room for improvement because we have encountered a lot of bugs especially on the development side."
"The price per user could be improved. We'd like for it to be more affordable."
"I haven't seen anything on AI merging with Relativity."
