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

"Cloudflare Access is a stable solution."

"The blocking feature is very good."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"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."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"The solution has different options that can be used to differentiate DDoS attacks."

"Clover is the best product globally."

More Cloudflare One pros

"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."

"If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing."

"The solution is very stable and extremely reliable."

"Microsoft Purview Data Loss Prevention has impacted the organization very positively by strengthening data security through automatically detecting and protecting sensitive information across emails, endpoints, SharePoint, and OneDrive."

"The product can block the uploads to cloud services."

"We have reduced sensitive data leakage incidents by 50 to 60 percent, which has lowered compliance and breach-related risks significantly."

"The policy customization feature is very useful, and we have successfully used the auto policy configuration."

"It has helped our clients to reduce the time to action on insider threats because it can be integrated."

More Microsoft Purview Data Loss Prevention pros

"My experience using Mimecast Insider Risk Management and Data Protection has been great."

"It's probably the best backup tool available, but that's just my opinion."

"Customer service is amazing with Code42, as everyone is very willing to help, very professional, and they take pride in their product and see this as a value."

"t has a very user friendly status bar with common errors and has logs built in to the console so we can review the issues or status of CrashPlan."

"The most valuable features for us are the training and support they provide, as well as ease of backup from the product."

"CrashPlan is an excellent backup product."

"Code42 CrashPlan is by far the best data backup solution on the market."

"The product just always has a continuous backup going, which is quite useful for us."

More Mimecast Insider Risk Management and Data Protection pros

Cons

"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."

"Our subscription plan for the solution has a limitation of bot signatures."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

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

"They don't have a person to provide support for customers using the solution under their free plan."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"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."

"For the topic of improvement, providing some training material is one of my suggestions."

More Cloudflare One cons

"The scalability, in terms of the portal, could be more user-friendly. Sometimes I have faced difficulties in identifying the options."

"I would assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect."

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

"The AI advancements can improve the false positives."

"Technical support seriously needs work. They are not helpful at all."

"It could cover more solutions and technologies."

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

"A site can have different containers where you store data. We have always wanted to apply compliance, labels, and policies at the container level, rather than to an outer shell or at the site level. That is something we have been looking forward to and I believe Microsoft is already planning something like that."

More Microsoft Purview Data Loss Prevention cons

"I think one we can improve is the compression."

"It is not cheap."

"The licenses are not so cheap, but are also scalable to your number of customers."

"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."

"Java needs to go away."

"Java, please get rid of Java."

"Sometimes we do encounter vague answers for some of the queries we have, but apart from that, the customer support response has always been very good."

"The application, written in Java, required far more system resources on a Client than other solutions."

More Mimecast Insider Risk Management and Data Protection cons

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

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

"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."

"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."

"You get the solution in a bundle if you get the E5 suite."

"It's a little bit pricey compared to competitors, but it's not too high."

"I am satisfied with the tool's pricing."

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

"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 cost works out to about $15 per user per month."

"Though I am not a specialist, the tool is quite expensive."

More Microsoft Purview Data Loss Prevention pricing and cost advice

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

"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."

"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."
