Increases data discoverability and boosts self-service analytics through enriched metadata and intuitive search
The best features that Alation Data Catalog offers are its search capabilities and the fact that it works with many different data platforms; it is essentially platform agnostic. The other piece that I really think is important is how easy it is to use as well as to manage. What makes the search capabilities of Alation Data Catalog stand out for me is the fact that every item within the catalog is indexed and searchable, as well as the filtering features that allow you to narrow down to just the types of assets that you need. Wildcard searches are also very helpful. It is a very intuitive tool, as long as you are using the filters. Alation Data Catalog has positively impacted my organization by allowing users to answer questions that they had without trying to track down an expert. This has saved them quite a bit of time and frustration. It has allowed them to solve problems they probably would not have been able to solve had they not had the catalog. We have been measuring the curation of content within the catalog that has gone up over time, and we have also seen the number of users in the catalog increase, as well as the amount of activity within the catalog increase. We were seeing about an average of about 20% increase month over month for the last few months.

There should be more customization options, as many things are restricted. This customization should suit individual needs, allowing for more UI customization, especially during consent collection. Also, improvements in data discovery and classification are needed, with the use of AI-oriented data discovery and more robust PDF file scanning capabilities. The scalability could be improved, particularly in detailed customization beyond the standard offering. Stability issues, like unexpected backend actions or data loss during updates, need to be addressed.

Pros

"Alation Data Catalog has positively impacted my organization by allowing users to answer questions that they had without trying to track down an expert, which has saved them quite a bit of time and frustration, and allowed them to solve problems they probably would not have been able to solve had they not had the catalog."
"Alation Data Catalog has positively impacted my organization by allowing users to answer questions that they had without trying to track down an expert, saving them quite a bit of time and frustration and allowing them to solve problems they probably would not have been able to solve had they not had the catalog."
"We had nothing before, so we can't compare anything we used before with what we've got now, but what we've got now is infinitely better."
"Given the relatively low level of maturity, Alation's most relevant feature at the moment is a user interface that's easy to navigate, which helps us find and understand the data. So while Alation has a lot more functionality, our pain point right now is being able to easily find, understand, and trust the information to use it."
"We do see a return on investment, though I cannot share exact numbers."
"We can customize templates based on our use cases."
"Alation Data Catalog positively impacts my organization by improving data efficiency, data quality, and collaboration, allowing analysts to spend more time on analysis instead of searching and preparing, so they can just start their analysis."
"We had some of our data science engineers, who had built out some cloud-based data and data products for users. They were spending a lot of their time, up to 30 to 35% of their time, answering questions about the data and helping people understand how to use it. Once they were able to document that information within Alation, they were only focusing on around 5% of the high-value questions that really couldn't be solved through the catalog itself. It freed them up to be more productive, it made their end-users more productive, and it made the adoption rate of their data products rise more quickly because people were able to get to using them."
"The data flow analysis is especially valuable from a security perspective. It helps set a perimeter concerning security aspects."
"It helps me in managing and using personal data while complying with the regulatory framework."
"OneTrust DataGovernance has excellent on-premise data mapping and visualization capabilities."
"The tool gives us the ability to trace the path of an incident."
"This allows anyone in the enterprise to easily find information about specific products or data elements."
"The product is easy to use, with excellent integration capabilities that, although they could be improved, are still better than other options."
"OneTrust allows seamless management of multiple geolocations at one time and offers workflow automation based on location-specific parameters."
"The platform enhances the collaboration between data governance teams and other business units."
 

Cons

"I know that this has been on their roadmap and they're working on it, but as a whole, there's an untapped reservoir of capabilities within their article features that could be used and built upon."
"It would be good if the tool could show the output from the records while querying."
"Sometimes the search function in Alation Data Catalog isn't as effective as it could be."
"Data observability within Alation would be incredibly helpful for addressing these challenges"
"I notice a couple of pain points with Alation Data Catalog: they can improve on the lineage perspective and improve their data sources integration."
"We have had issues setting up the connectors and getting Alation's support team to resolve issues."
"Alation Data Catalog can be improved by treating areas that could incorporate best practices or improvements, such as identifying data domains, which refer to logical data groups customers, vendors, and other entities."
"I know that this has been on their roadmap and they're working on it, but as a whole, there's an untapped reservoir of capabilities within their article features that could be used and built upon."
"Deployment is a big issue."
"The integration with third-party products could be better."
"The process management capability could be improved. It would be beneficial to have an authorization mechanism for users to process certain actions."
"The subject rights and concerns functionality needs to be improved."
"To succeed in this market, OneTrust needs to invest more and check the requirements from Saudi Arabian regulations."
"In OneTrust DataGovernance, there is room for improvement in creating customized email notifications in plain language and enhancing text editor features for form creation."
"Stability issues, like unexpected backend actions or data loss during updates, need to be addressed."
"The platform could benefit from more competitive AI features, more user-friendly dashboards, and better automatic recognition or advanced templates."
 

Pricing and Cost Advice

"The platform is moderately expensive compared to the other competitors in the market."
"I don't have all the details on the pricing side, but the solution was more expensive than originally expected."
"A three-year agreement is better than a one-year rolling 12-month agreement from a price point of view. I'd recommend looking at a three-year deal because you can't stand up a catalog and produce value in 12 months."
"The solution is a little expensive."
"The product is worth every penny."
"The solution is a low-cost option."
"There is a licensing fee that we pay regularly."
"The product cost was reasonable due to a discount for NGOs."
