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.

Quotes from Members

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

Pros

"Cloudflare, in my opinion, was easy to implement."
"The blocking feature is very good."
"Cloudflare is simple to use."
"I'm very satisfied with the environment and the dashboard."
"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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Its total protection has been the greatest aspect since it completely protects all the mail from the cloud."
"It has just been phenomenal."
"The solution helps to block spam emails."
"It fully protects colleagues from visiting insecure sites and browsing in unhealthy environments."
"It is very intuitive. It is a point and click type of deal."
"One of the best features is the analysis and emulation carried out with each file attached to the emails, which makes each of the deliveries we make via email more secure."
"I appreciate the ease of deployment and the intuitive dashboard. Even someone with basic IT knowledge can easily understand the dashboard and identify potential threats."
"Check Point is a leader in the market."
"The solution's IDM (Indexed Document Matching), EDM (Exact Data Matching), and DCM (Described Content Matching) features have been most effective in identifying and mitigating potential data leaks."
"The feature I appreciate most about Microsoft Purview Data Loss Prevention is the native synchronization between the tool and all the Office applications that the customer already has."
"When you are going to use Microsoft Purview Data Loss Prevention, most of the setup is already done by default as per your needs."
"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."
"It has helped our clients to reduce the time to action on insider threats because it can be integrated."
"The solution is very stable and extremely reliable."
"Microsoft Purview has helped improve my company's ability to discover sensitive data, as most companies would say that they improved in the whole posture on this field."
"Microsoft Purview Data Loss Prevention has significantly improved our data security posture by reducing the risk of accidental data leaks and helping to meet compliance requirements."
 

Cons

"The response time for support must be reduced."
"For the topic of improvement, providing some training material is one of my suggestions."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"The initial onboarding was causing us some confusion."
"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."
"It would be good to have the option to export the respective record data from dashboards or logs to .csv or other files."
"Since the portal to the management and administration entry sometimes has performance problems and takes a long time to respond to what has arrived, the handling of the tool is difficult."
"I need to go to Check Point's admin portal if I want to see the license list and the details of the users of the tool, making it an area of concern where some ease of process should be provided from an improvement perspective."
"Sometimes they do not provide immediate assistance, and it can take time for them to respond."
"The implementation could definitely be better. We had great support from Check Point, but there were some "got-you" moments where we got surprises as we were setting it up."
"Integration is currently limited to Microsoft Office 365 and Google G Suite."
"They should consider a module that allows the customizing of reports so we can generate executive information for the client (to explain in simple language the general security situation in the SaaS environment)."
"The sanitization on the file needs improvement."
"We faced a performance issue with the tool when we didn't get alerts for file uploads."
"There is a lot of ambiguity when you are setting up labels, such as sensitive information labels."
"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."
"Technical support is awful."
"The platform can be challenging to navigate and has the potential for improvement."
"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."
"The main disadvantages of Microsoft Purview Data Loss Prevention in comparison to the Netscope product are notable considerations."
"Microsoft Purview Data Loss Prevention's licensing is expensive."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"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 is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 solution is not that expensive."
"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 price is very good, based on what they deliver."
"Usually, we pay for the licensing part on a yearly basis and not on a monthly basis. If Check Point's team is providing a good amount of discount, then it is very easy for us to select it since its competitors are also giving the best prices or best discounts."
"The pricing is competitive."
"The difference between [Check Point and its competitors] boiled down to money. Price-wise, Check Point was very good, it was very competitive."
"Reasonable cost, quick and easy implementation, and transparent."
"One of the nice features is that the licensing model is elastic, so if you go over your license count, you can add users during your billing cycle and true-up later."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"The product is expensive."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"It's a little bit pricey compared to competitors, but it's not too high."
"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."
"I am satisfied with the tool's pricing."
"The cost works out to about $15 per user per month."
"Though I am not a specialist, the tool is quite expensive."
"The product has the best price-to-performance ratio."
"The solution’s pricing is reasonable."
