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.

Pricing and Cost Advice

"The solution's pricing lacks transparency."

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

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

"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 is not that expensive."

"The prices are slightly expensive."

"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."

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

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

"The solution’s pricing is reasonable."

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

"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."

"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."

"The pricing is reasonable."

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

"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."
