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.

Gateway policies have greatly reduced phishing emails and support rapid investigation workflows

There are no particular reviews on improvement from my side regarding Mimecast Insider Risk Management and Data Protection.I think the UI of Mimecast Insider Risk Management and Data Protection can be more optimized, as it feels slow and laggy at points. If that can be optimized and improved, that would be better.

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 part of the Zero Trust philosophy."

"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."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."

"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 blocking feature is very good."

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."

More Cloudflare One pros

"Microsoft Purview Data Loss Prevention's responses are faster. Its installation is also reliable. The security score helps with the security part."

"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."

"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 auto-labeling feature is definitely the most valuable feature. It goes in and labels the documents for you in different repositories. It covers the Outlook and Exchange repositories along with SharePoint and OneDrive. It is really helpful in those areas."

"The most valuable features are identifying sensitive data and issuing alerts."

"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."

"My favorite feature about Microsoft Purview Data Loss Prevention is actually quite simple: there's a handful of things that you do, you create a new batch, it'll give you a unique ID, you copy that unique ID, it's a URL, and then you can put that into a script that we wrote so we just paste that in our script and then it uses that URL to upload all of those mailboxes, and then we can use that to import."

"The tool's most valuable feature is in the area of OCR."

More Microsoft Purview Data Loss Prevention pros

"It has saved many users from the loss of hundreds of hours of work."

"Backup and recovery have been great, but I love having the ability to keep the hybrid type build which they offer."

"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."

"The reason for us moving over to CrashPlan was cost and retention, as we saved the company $6000 a year using CrashPlan and no more "surprise, you are out of space" messages."

"CrashPlan has proven to be a backup AND restore solution when other solutions were only "good" at backing up."

"I'm still new to it; I think right now I am 90% happy with it."

"Customer Service: I won't even bother rating them because they are in a class of their own."

"If you treasure your digital content – this is the solution for you."

More Mimecast Insider Risk Management and Data Protection pros

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

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

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"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."

"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 customers no longer use Cloudflare because its service is subpar."

"Feedback could be enhanced."

More Cloudflare One cons

"The tool's user interface and document fingerprinting have been very poor for my customers because uploading files manually can be problematic."

"A major improvement is required in the solution's incident handling and alerting."

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

"At this time, I have not seen a return on investment with Microsoft Purview Data Loss Prevention."

"More training for end users on how it works would be beneficial."

"There is a need for improvements, particularly in ensuring that file-based recognition is more reliable and comprehensive."

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

"We faced a performance issue with the tool when we didn't get alerts for file uploads."

More Microsoft Purview Data Loss Prevention cons

"Not available for iPads yet."

"Due to recent changes that effectively abandoned an entire segment of their user base, I no longer trust nor can recommend Code42 products."

"Download speeds could be faster when restoring from the cloud."

"My only real criticism with Code42, is that in the last year they have not focused sufficiently on the development of CrashPlan."

"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."

"Java, please get rid of Java."

"The login screen for customers could be improved, I find that the white and grey could be hard to read for some customers depending on the brightness of their screens."

"Java needs to go away."

More Mimecast Insider Risk Management and Data Protection cons

Pricing and Cost Advice

"The solution is not that expensive."

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

"The solution's pricing lacks transparency."

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

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

"The prices are slightly expensive."

"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 is reasonable."

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

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

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

"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."

"If one is very cheap and ten is very expensive, I rate the price as one out of ten."

More Microsoft Purview Data Loss Prevention pricing and cost advice

"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."

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

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

"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."

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