ROI

Sentiment score

Microsoft Purview DLP offers cost savings, security enhancements, and reduced onboarding time, though ROI varies among users.
Sentiment score
8.0
Trellix DLP offers enhanced security, significant cost savings, 20% ROI, and increased popularity due to its McAfee transition.
The benefits our customers see from using Trellix DLP include cost reduction, given its competitive pricing in India.
 

Customer Service

Sentiment score
5.1
Microsoft Purview DLP support is inconsistent, with quick responses and clear resources but also delays and monopolistic concerns.
Sentiment score
6.5
Trellix DLP support is generally satisfactory but affected by rebranding issues, regional variations, and delays, especially during night hours.
Once we got to the Microsoft engineers, the experience was great.
We received prompt technical support and remote sessions when necessary.
Trellix's technical support deserves a perfect rating, and I would rate it ten out of ten compared to other solutions.
The support from both the vendor and Trellix is excellent.
 

Scalability Issues

Sentiment score
7.6
Microsoft Purview Data Loss Prevention offers scalable, flexible cloud solutions, but needs improvements in user-friendliness and device-level scalability.
Sentiment score
7.7
Trellix DLP is scalable and adaptable, favored in cloud and on-premises setups for growing infrastructure needs.
The policy working and detection technology need enhancements.
Trellix DLP is very scalable, especially with the cloud version as everything is managed in the cloud.
It's a bit of a fallback, and I know they are working on improving scalability.
I would rate the scalability of Trellix DLP between eight to nine out of ten.
 

Stability Issues

Sentiment score
7.8
Microsoft Purview Data Loss Prevention is highly stable, reliable, and responsive, though minor real-time issues and internal connection challenges exist.
Sentiment score
8.0
Trellix DLP is stable on Windows but faces inconsistencies on Mac OS; cloud provisioning minimizes concerns.
Sometimes the solution is not stable when the internal connection is not reliable, so this aspect needs improvement.
With the move to cloud provisioning, that is not a big problem anymore due to scalability on Trellix's side.
The agents are the main issue as they can behave inconsistently across different versions of operating systems.
Product stability is not a major concern; I would rate it 99% stable.
 

Room For Improvement

Microsoft Purview DLP needs better integration, improved UI, enhanced AI features, cost-effective licensing, and better language support.
Trellix DLP requires better support, enhanced UI, compatibility, cloud integration, machine learning, and efficient policy application.
Implementing a degree of severity ranking is essential.
Endpoint Data Loss Prevention needs to be improved as it is not up to expectations.
Having someone within a region who understands the countries and how they approach data and information security is sometimes where the problem lies.
Improved compatibility with Mac OS is needed due to ineffective policy applications.
The product also faces challenges with high CPU and memory utilization, impacting endpoint performance.
 

Setup Cost

Microsoft Purview DLP in E5 licenses offers competitive pricing and flexible payment, valued for security features and added services.
Trellix DLP pricing is user-dependent, device-based, and considered reasonable, but can be high due to currency conversion.
It used to be in the middle, tending towards the high end, especially in South Africa, where we need to convert from dollars to rands, making things very expensive quickly.
The solution is currently affordable and not considered expensive.
 

Valuable Features

Microsoft Purview DLP enhances data security with auto-labeling, multi-cloud support, cross-platform protection, and strong compliance features.
Trellix DLP offers advanced data protection with templates, centralized management, comprehensive security features, and compliance tools, enhancing system management.
Microsoft Purview Data Loss Prevention usually performs well, except for endpoint Data Loss Prevention, which may need improvements.
The feature I find most valuable that I'm currently using is the quickness of the emails that the Microsoft Purview Data Loss Prevention solution sends to us, where we get notifications that say a user has potentially breached our data guideline rules, and we get those alerts continuously, allowing us to enforce them manually.
Trellix products are manageable through a centralized control center, meeting requirements from frameworks like PCI DSS.
Additionally, it supports integration with third-party solutions and agents, providing a versatile and user-friendly management experience.
These features are very useful for protecting company confidential data from being copied to another remote location or other sites.

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.
