Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Protects sensitive data across devices and helps address client compliance needs proactively

The reporting in Microsoft Purview Data Loss Prevention is a little easier than most Microsoft portals. I understand the licensing cost, especially if you're a Business Premium or in the SMB world, and a lot of clients run with a Business Premium. That comes with data loss prevention in a manual process, whereas E5 gives automation. Microsoft has said, 'Okay, here's your Microsoft 365 E5 compliance add-on that can go on the Business Premium.' So Business Premium users can get the data loss prevention features of E5, which is fantastic. That was the big point that they were missing, and I'm glad that they actually have an add-on now that makes it possible. So truly, I don't think there's a downside. Maybe more reporting, but that's it.

Provides comprehensive visibility and protection, helps in identifying the gaps in security, and comes with excellent onboarding support

In a couple of instances, we had a little bit of trouble in getting it distributed throughout the organization. We ultimately managed to do it, but they talk about it being a pretty simple process, and it became a little laborious. It would just turn away. The agents were not being distributed. It was just churning and churning and churning. When we were looking for specific categories of data, it was getting bogged down, but that was not even so much Code42, although some of it was their issue. It really has to do with the overall infrastructure and what the organization is prepared to do. If the infrastructure or the networking is a little hinky or you don't have a really finely tuned network infrastructure environment and your patches aren't up to date on your servers and your endpoints, it could get a little sticky. Other than that, it was okay. We really didn't have much problem beyond that. It took a couple of days to sort that out, but it was no big deal.

More Mimecast Insider Risk Management and Data Protection pros

Cons

"Operating and tuning the product is difficult."

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"Lacks a VPN feature to provide a secure connection to the data center."

"The initial onboarding was causing us some confusion."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

More Cloudflare One cons

"The only concern is that it forces clients to use an expensive license."

"I would like Microsoft Purview Data Loss Prevention to be on the source code or SQL databases. It is difficult to do classification and labeling when you have a third-party source code or a third-party Oracle database."

"The major challenge we had was overreach. When our initial design inception blocked more data than we expected, we had a lot of help desk related issues that we did not see in testing."

"I rate the overall solution 3 out of 10."

"Perhaps with the advent of AI, it can be enhanced, especially with organizations that handle and process huge amounts of data."

"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."

"The solution should provide better integration with other systems."

More Microsoft Purview Data Loss Prevention cons

"Reporting could be stronger. With the API you can do a lot of reporting, but it is not built in very robustly."

"The GUI doesn't always show the most current settings upon opening a screen."

"From time to time, you will see issues with the software not connecting to the on-premise server, or the client crashes on a users machine."

"I would like to see more flexibility on privileges, perhaps create another kind of admin for regions. Also, I would like the ability to access logs without having to be on the actual device or a super-admin."

"I'd like to see some better options with account management in the software and a simpler way to track where you are using licenses."

"There doesn't seem to be any feature that is lacking."

"It's not available for iPads yet."

"This is my only major issue with Code42 at this point."

More Mimecast Insider Risk Management and Data Protection cons

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The product has the best price-to-performance ratio."

More Microsoft Purview Data Loss Prevention pricing and cost advice

"It was expensive. It was more expensive than Eureka, and it was more expensive than Barracuda Backup, but what we got was a full team. They didn't come in and nickel and dime us. They provided the assistance we needed. They didn't say that they need to charge us for something or it is going to take another statement of work. It was all bundled into it... We pay for the software maintenance. It is probably 18% or 20% of the license fee for rev releases."

"The pricing is reasonable. It's my understanding that the cost is about $7 for unlimited storage in the cloud per server."

"They were the best solution and surprisingly enough, the cheapest."

"It used to be a good solution for SOHO in particular as it had unlimited storage for a reasonable price. However, their pricing model has changed and they are now primarily targeting enterprise users."

"It is 100% worth the cost to get and keep the support, especially when setting it up."
