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.

Email security has blocked sophisticated phishing and now protects inboxes with AI detection

The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.

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.

Pros

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."

"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."

"I'm very satisfied with the environment and the dashboard."

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

"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."

"Cloudflare is simple to use."

More Cloudflare One pros

"The anti-phishing feature is the solution's best feature."

"The ease of management and intuitive administration are excellent."

"Overall, this is a solution that we are absolutely satisfied with and I definitely recommend it."

"To provide the security coverage to the new email service, we chose the Check Point CloudGuard SaaS solution, which now serves as the main protection mechanism for about 500 users and up to 10,000 emails per day, and there are no problems with the scalability for future growth."

"The deployment itself is quite seamless; you can use their temporary licenses for the deployment, just for testing."

"The dashboard provides information to investigate more about malicious activity and blocked emails."

"The main benefit is that hackers can't steal information."

"Checkpoint Harmony Email and Collaboration has significantly improved our email security by effectively blocking phishing, malware and ransomware threats."

More Check Point Email Security (formerly Harmony Email & Collaboration) pros

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

"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 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."

"One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site."

"We have not seen any sensitive files leave via email, which represents a significant improvement."

"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 solution's most valuable feature is the mature O365 DLP, which works with SharePoint and Teams."

More Microsoft Purview Data Loss Prevention pros

Cons

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

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

"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."

"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."

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

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"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."

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

More Cloudflare One cons

"Sometimes they do not provide immediate assistance, and it can take time for them to respond."

"A signature-based filter could improve the solution's AI model for spam email."

"I would love it if they would do some work on the Postgres definition on the back-end."

"Check Point's technical support is very much of a low level, especially with respect to other vendors and OEMs."

"There are sometimes leakages of viruses when the system is experiencing network failures."

"They must provide security to more email service providers."

"Check Point Infinity Portal sometimes feels a bit slow, and there are performance issues that should be easy to fix."

"I would rate the customer support a four, maximum, because I have had to reach out to them, and it wasn't great. I ended up with a technician that didn't actually know how to resolve the issue and was just doing basic level one troubleshooting, so it was very time-consuming to work with them."

More Check Point Email Security (formerly Harmony Email & Collaboration) cons

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

"I would say the improvement of Microsoft Purview Data Loss Prevention could be in the propagation of policies, as if you create a policy, it may take up to 48 hours to propagate to devices, and this might take a little bit longer than ideal."

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

"Microsoft Purview Data Loss Prevention's licensing is expensive."

"Because it's an academic institution, we got really excited about the level of granularity we could implement, but that granularity overwhelmed our users."

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

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

More Microsoft Purview Data Loss Prevention cons

"The solution is not that expensive."

"The solution's pricing lacks transparency."

"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."
