Data discovery has transformed compliance workflows and automation now speeds up requests and remediation
The best feature that BigID offers is data discovery and classification, which is the most powerful engine. It allows connecting to many different data sources, ranging from cloud to on-premises to structured to unstructured data. If there is no connector available, you can build your own classifiers as well. Regarding the custom classifier option, you can build custom classifiers using regular expressions, and I have done that if you know how to create regular expressions. Custom connectors are something you create to connect to a database where the connector is not available. BigID has positively impacted my organization as it's a very powerful tool, especially with the increasing regulatory compliances for different countries such as GDPR, CCPA, and India's recent DPDPA act. Having these tools in place greatly helps organizations avoid any penal charges for not being compliant with the regulatory compliances. For example, regarding compliance or reduced risks for my clients, the DSAR process I was talking about allows organizations to respond quickly to user data deletion requests under GDPR law, which traditionally has a 30-day or 60-day timeline. In larger organizations, when the number of requests is high, it becomes tedious. However, using DSAR automation with BigID, it's almost instantaneous; instead of 30 days, you can respond in just one day to what users have requested.

Workflow automation has streamlined privacy assessments but data discovery still needs improvement
OneTrust Privacy can improve in the area of data discovery and classification. While it is capable in terms of assessments and similar tasks, there is room for improvement when it comes to connecting to different data sources. I suggest that there is an area for improvement in terms of customer support. Having a direct communication channel for partners without needing ticketing would be helpful.

Quotes from Members

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

Pros

"One of the most valuable things in a data-focused world is a tool, a technology that's data-centric, not trying to master data management or whatever else. It's a source of truth for what data an organization holds, giving it the ability to catalog, categorize, and understand its data."
"Although I was serving the client rather than my own organization, BigID has made scans faster and more efficient, and the DSR results are much more accurate."
"BigID's scanning feature is its most valuable component."
"BigID has one of the best technical support teams."
"My experience with BigID has been very positive and memorable, as BigID is simple, straightforward, and reliable when it comes to data discovery and data scanning exercises."
"It provides a unified view across different databases and supports a wide range of data source types, including cloud and on-premises systems."
"BigID is more advanced than Microsoft Purview when it comes to machine learning and AI development tools."
"The best feature that BigID offers is data discovery and classification, which is the most powerful engine, allowing connection to many different data sources ranging from cloud to on-premises and from structured to unstructured data, with the ability to build your own classifiers if no connector is available."
"OneTrust Privacy has positively impacted my organization by enabling us to implement different clients' data privacy programs successfully, and it is a very helpful tool for that purpose."
 

Cons

"Some users find catalog navigation challenging due to the lack of a search-by-column feature, which makes it difficult to locate specific data quickly."
"I want them to focus on data mapping, assessment, automation workflow, and privacy incident management. The privacy tools have not been widely used, and they have not invested much in privacy code privacy tools."
"BigID's user interface was problematic as it was not very user-friendly, though I believe it improved over time."
"In terms of what could be improved, when you're looking in a BigID file, you cannot really get the whole file. You have to export it to download it to another platform that allows you to completely view it, or run a program. That was one of the things that was really a disappointing point for me. Not to be able to view everything. There's a lot more data, but you can't get it all at once."
"One area where BigID can be improved is the UI, which has a lot of bugs."
"There are some shortcomings when it comes to Calvirus authentication, which is not yet supported by BigID."
"In terms of what could be improved, when you're looking in a BigID file, you cannot really get the whole file. You have to export it to download it to another platform that allows you to completely view it, or run a program."
"I want them to focus on data mapping, assessment, automation workflow, and privacy incident management."
"OneTrust Privacy can improve in the area of data discovery and classification. While it is capable in terms of assessments and similar tasks, there is room for improvement when it comes to connecting to different data sources."
 

Pricing and Cost Advice

"The product is expensive, but so are all competitor tools"
"The pricing depends. If you have thousands of data sources to connect and manage, and you struggled with an MDM package in the past, you'll find BigID valuable and even cheap. But if you're a small business, it's probably not the right tool for you."
"The solution is expensive."
"I think that BigID's pricing is very reasonable."
"The solution is not licensed per user but rather based on capacity. For instance, organizations with large amounts of data, such as 50 GB or more, are the ones that typically qualify for BigID."
