Automation has given us consistent analytics and improved quality of insights into user activity
One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.

Distributors highly benefit from advanced data monitoring and seamless integration features
The Machine Learning capability could be improved, particularly in data discovery. When given sensitive data expressions, the system retrieves files that are not always related. The system should adhere strictly to the given expression rather than just focusing on keywords within the expression. In endpoint features, while the detection rate is good, there could be improvements in remediation and rollback solutions during attacks. Other solutions now include such options since providing 100% security is impossible. The flexibility varies across environments. Enterprise customers find the product performs well without affecting their data, with scans running as scheduled. However, SMB customers experience some performance issues during scanning. Since EDR is integrated, users must access the EDR console to check endpoint detections. It would be beneficial if this functionality were incorporated within the EPO console, as the current threat graphs link doesn't display endpoint threat graphs.

Quotes from Members

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

Pros

"It has helped our clients to reduce the time to action on insider threats because it can be integrated."
"The product can block the uploads to cloud services."
"It's secure and can be integrated with an existing Forcepoint DLP setup."
"Insider risk management and data retention are beneficial."
"One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site."
"There's a good amount of documentation in case you run into any problems."
"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."
"I rate Microsoft Purview Data Loss Prevention's stability a ten out of ten."
"The tool has prebuilt templates for data classification. It is easier for customers to get started."
"Trellix DLP offers many features, using EDR, EPP, disk encryption, and other features."
"The support from both the vendor and Trellix is excellent."
"I rate the product an eight out of ten."
"It prevents enterprises from installing external software and devices and can block specific network pathways."
"Scalability is feasible since it's on-premises. It's easy to scale there."
"The most effective aspect of Trellix DLP is that it does what it's supposed to do. It is fairly simple to use compared to Proofpoint."
"The most effective aspect of Trellix DLP is that it does what it's supposed to do."
 

Cons

"There is no AIP for Linux systems. That's a setback. Another thing it's lacking is libraries to work with Python. It has libraries for C# and C++, for example, but not for Python and, these days, Python is very useful."
"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."
"Technical support is awful."
"Improving Microsoft Purview Data Loss Prevention would involve recognizing that the whole AI path we are all on is going to help, given the massive amount of data we handle; even if there are true positives, implementing a degree of severity ranking is essential."
"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."
"We faced a performance issue with the tool when we didn't get alerts for file uploads."
"I rate the overall solution 3 out of 10."
"There is a lot of ambiguity when you are setting up labels, such as sensitive information labels. It is a little daunting at first if you don't have prior knowledge, and there is a little bit of a learning curve for setting up the labels. Some of the setup wizards could be more helpful from an AI perspective. They can streamline the setup through more AI technologies so that you don't have to jump through so many hoops and different menus and dropdowns. It would be useful to have a setup wizard that is more hands-off and engaging for setting up the information type labels. If you tell them this is what we're trying to protect, it should basically start to lead you down that path of best practices. Such a feature would be great."
"When cases are raised, partners perform initial L1 or L2 troubleshooting. However, ticket resolution times are often too long, with new engineers sometimes requesting the same logs repeatedly."
"The whole UI of the server console installed on the standalone computers is hefty."
"Trellix needs to improve customer support."
"I would rate the solution seven out of ten based on my last experience within the last six months. It's a bit of a fallback, and I know they are working on improving scalability."
"The main issue I have currently is with technical support."
"Coverage for Mac OS is lacking as features like clipboard and print protection don't function as expected. The agents often affect endpoint performance negatively and do not behave consistently across all machines."
"It's not very user-friendly for a beginner, so it would be easier if the platform or console were manageable or user-friendly. The dashboard could be simplified."
"Having someone within a region who understands the countries and how they approach data and information security is sometimes where the problem lies."
 

Pricing and Cost Advice

"The cost works out to about $15 per user per month."
"Though I am not a specialist, the tool is quite expensive."
"The product has the best price-to-performance ratio."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"The pricing is reasonable."
"It's a little bit pricey compared to competitors, but it's not too high."
"I am satisfied with the tool's pricing."
"It is a part of our Microsoft licensing. We pay for a yearly renewal. Its price is reasonable for the size of the organization we are. It is fairly competitive, and you get what you pay for. We have an E5 license, and a part of understanding the E5 license is to see what all you get with it. If you really look at it from that standpoint, you get a lot of value. You have Defender and all its security features in there as well. Their licensing is fairly flexible. They have different programs. We've seen ones where you could pay for up to three to five years in advance. There is also a monthly pay-as-you-go type of deal, but we're doing a yearly renewal and fixing the budget."
"The pricing depends on the number of users in a company."
