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.

Integrated controls have reduced insider risk and now protect sensitive data across our workforce
One standout feature about Microsoft Purview Data Loss Prevention is the tight integration with Insider Risk Management and Defender XDR, as it gives much better context during investigations instead of treating DLP as an isolated alerting tool. We also use endpoint DLP heavily to control USB, copy, print, clipboard, and browser upload activity, which has been very effective for remote workforce security. The best features Microsoft Purview Data Loss Prevention offers include real-time policy enforcement, endpoint DLP, and deep integration with Microsoft 365 plus Defender XDR. We also heavily rely on sensitive information type detection, adaptive policy tips, and insider risk integration to investigate suspicious user behavior with proper context. Another standout feature is the ability to control USB copy, browser uploads, print clipboards, and cloud sharing actions directly from endpoint policies. The integration with Microsoft Defender 365 and Defender XDR helps our team in day-to-day operations because DLP alerts are automatically correlated with endpoint identity, email, and user activity telemetry, which helps the SOC investigate incidents much faster from a single workflow. The sensitive information type detection makes a difference compared to other tools we have used because it is more effective than many legacy DLP tools. It understands context, exact data patterns, document labeling, and Microsoft 365 native content, reducing false positives while improving detection accuracy. Another strong feature of Microsoft Purview Data Loss Prevention is auto-labeling and policy inheritance with Microsoft's Information Protection, which helps maintain protection even after files are shared or moved across workloads. We also value the user coaching or policy tip capability because it educates users in real time instead of only blocking actions, which reduces repeated DLP violations significantly.

Insider threats have been detected faster and internal data exposure is now controlled
Regarding how Mimecast Insider Risk Management and Data Protection can be improved, sometimes the tool is slightly laggy, wherein it would take some time for us to fetch the related logs from the Mimecast portal, and that of course can be improved. There could also be a graph or a kind of a graph where, if the organization has a smaller number of employees, it is fine, but if it has a large number of employees and different departments, then in that case, Mimecast could give us an AI suggestion upon how to improvise the current security posture, how we stand and where we can go up to in terms of implementing or tweaking the policies. As the organization's size gets bigger, it would also be better if Mimecast could provide some solutions upon how to segregate the users into groups and what groups can have which policies. Those kinds of features can be added. Regarding Mimecast Insider Risk Management and Data Protection's AI capabilities, I think its governance and security could improve as I am not entirely sure how it works. It would be helpful if Mimecast could, as the AI capabilities are in place, maintain a strict governance policy upon the data that is being processed, especially for user personally identifiable information. As insider risk management sometimes also gets into the personal details of the user, organizations might be hesitant; even we are also hesitant to use the AI capabilities. If Mimecast could provide more information about how they store the data and whether the agents are local agents or cloud-hosted agents, that would be of great help for the organizations to consider its AI capabilities while adhering to the compliance needs of a particular organization.

Quotes from Members

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

Pros

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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."
"Clover is the best product globally."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"The blocking feature is very good."
"It will take the blow rather than our applications should an attack occur."
"It is a stable solution."
"The solution has different options that can be used to differentiate DDoS attacks."
"Microsoft Purview Data Loss Prevention has absolutely helped improve my organization's ability to manage data because we use M365 for the majority of our knowledge worker storage, and that's where people's data lives."
"The solution's most valuable feature is the mature O365 DLP, which works with SharePoint and Teams."
"There's a good amount of documentation in case you run into any problems."
"Earlier, our customers had no control at all over compliance, and confidential documents that were going out were not at all looked into, and Microsoft Purview Data Loss Prevention has been a huge benefit to our clients in this regard."
"The solution is very stable and extremely reliable."
"Microsoft Purview's classification and policy controls impact users' productivity within my organization very positively, as it does not get in the way of their working."
"The impact of Microsoft Purview Data Loss Prevention's classification and policy controls on our productivity within our organization is significant, as it's helped our security team."
"For Purview's natively integrated compliance across Azure, Dynamics 365, and Office 365, I would give it a 10 out of 10. It provides all the insights and information."
"Backup and recovery have been great, but I love having the ability to keep the hybrid type build which they offer."
"Since I started working with CrashPlan we have less tickets open, since we offer monitor issues we received daily alerts and most of the issues are fixed even before the customer realizes they have an issue."
"This is by far the best cloud-based backup solution."
"One of the most stable software packages I have worked with in my 20 years in IT."
"I'm still new to it; I think right now I am 90% happy with it."
"It has quite a bit of flexibility in configuring backup sets."
"For the investment made, we have saved the company tens of thousands of dollars from ransomware and human error."
"The main plus for us is 95% of restores globally are all self-service."
 

Cons

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Feedback could be enhanced."
"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."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"Cloudflare DDoS has poor technical support."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The AI advancements can improve the false positives."
"Some main features are limited in comparison to other solutions."
"Because it's an academic institution, we got really excited about the level of granularity we could implement, but that granularity overwhelmed our users."
"Microsoft Purview Data Loss Prevention could be improved with simpler policy configuration, a more robust reporting dashboard, and better support for third-party applications outside the Microsoft ecosystem."
"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. It is seamless when it comes to Microsoft documents but is not so with third-party source codes. Microsoft needs to work on it a little bit more."
"The stability and reliability of Microsoft Purview Data Loss Prevention is great. Besides the weird timeframe where it takes a couple hours for a rule to sync and 24 hours to appear for someone, I don't really have an issue."
"All the security operations are better defined in Forcepoint, while in Microsoft Purview Data Loss Prevention, you will have to use a specific workflow and then an application to release blocked emails."
"Endpoint Data Loss Prevention needs to be improved as it is not up to expectations."
"I would love to have an app on my phone to give me status updates on the backup system and push me notifications if something goes offline or has an issue so I wouldn't have to go look at the dashboard as much."
"It's not available for iPads yet."
"If anything, make integrating cloud storage a little bit easier - I'd love to be able to choose the cloud I'm going to push to, but it's hard to find instructions for doing that."
"You can't always filter out data that you'd like to."
"It is a little confusing for users when they are replacing a laptop - a couple have wiped out their backup by choosing "adopt" before they do a restore."
"Our client has chosen Proofpoint over Mimecast Insider Risk Management and Data Protection because they are highly recommended to the Proofpoint solution rather than Mimecast Insider Risk Management and Data Protection."
"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."
"Not available for iPads yet."
 

Pricing and Cost Advice

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The solution's pricing lacks transparency."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"The solution’s pricing is reasonable."
"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."
"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"The product has the best price-to-performance ratio."
"The cost works out to about $15 per user per month."
"Though I am not a specialist, the tool is quite expensive."
"The pricing is reasonable."
"It is 100% worth the cost to get and keep the support, especially when setting it up."
"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."
"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."
"The pricing is reasonable. It's my understanding that the cost is about $7 for unlimited storage in the cloud per server."
