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 protection has stopped phishing and secured cloud collaboration across all devices

Deployment is very easy since it is API based and does not require any harsh configuration. The DMARC management and DMARC forensic is the best feature. Their security engine provides everything such as DLP and encryption. Check Point Harmony Email & Collaboration provides almost 100% security for phishing emails. Their DMARC management is very standard compared with any other brand or any other email security provider. The best thing is that on a single tenant I can manage multiple services such as Harmony Endpoint, Check Point Harmony Email & Collaboration, Harmony Browser, mobile security, EDR, XDR, which is endpoint security, and SaaS. All of these services have a single dashboard. When giving security to email, in Check Point Harmony Email & Collaboration, I do not need to change any MX record or any DNS entry changes. I simply add one text record for DMARC and no changes are needed in the MX record of that particular domain. This is very easy because Check Point Harmony Email & Collaboration is in the tenant of Microsoft Office 365 and Google Workspace only. Check Point works on zero trust network technology. They are not only giving a feature of artificial intelligence but also machine learning summary. Machine learning summary is also given when they catch any kind of incidents such as phishing attacks, malware attacks, and ransomware attacks. They always provide real-time alerts for that. Real-time URL analysis is provided for phishing links and all these things. It gives 100% output for that and shows the source from where the malicious URL comes from. Additionally, they always provide threat emulation. This means the simulation of what danger happens when I click that particular URL is also provided in their report. It gives 100% protection to all BYOD devices. For example, one single Microsoft 365 account can be configured on different five devices. Many companies give email access to their employees on their mobile as well. In that case, if any malicious file is on the mobile and the employee would like to save it on OneDrive, due to this security, the user and administrator will get a real-time alert that this file is malicious and cannot be uploaded to OneDrive. This not only saves money but also saves time and prevents the organization from such cyber attacks.

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 DDoS mitigates DDoS attacks."

"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."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"Enables me to work from two locations."

"The blocking feature is very good."

"Cloudflare Access is part of the Zero Trust philosophy."

"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."

More Cloudflare One pros

"The most valuable feature is spam detection and phishing site prevention, which Microsoft couldn't catch, yet Check Point does."

"It seems quite scalable. We don't anticipate any scaling issues. We have it deployed in the cloud."

"After we organized it with the consulting company and set the first rules, after one week the system seemed to have learned the company's pattern, and we managed to achieve a reduction of almost eighty to ninety percent on spam and false emails, which was very good at the time."

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

"It fully protects colleagues from visiting insecure sites and browsing in unhealthy environments."

"Check Point has made my threat prevention better; it has helped me avoid having to redo machines and has helped protect our data by not letting unauthorized items through."

"The fact that we can share documents without emailing them and still be confident they will go through the corresponding scrutiny is great."

"This DLP is very useful, as it gives our users additional protection."

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

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

"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."

"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 Data Loss Prevention protects the organization from user data getting out that should not be out and works very well when assessing the ability to prevent unauthorized sharing of sensitive information."

"I rate Microsoft Purview Data Loss Prevention's stability a ten out of ten."

"I like the sensitivity labels and data security posture management for AI."

"We can use Microsoft Purview Data Loss Prevention to manage devices and site policies."

"It's secure and can be integrated with an existing Forcepoint DLP setup."

More Microsoft Purview Data Loss Prevention pros

Cons

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

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

"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."

"The initial onboarding was causing us some confusion."

"The onboarding process can be improved a little bit."

"Operating and tuning the product is difficult."

"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."

More Cloudflare One cons

"Its guides are not great."

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

"The next release should focus more on email categorization and provide options for unlocking blocked safe emails."

"Check Point should integrate with features available in Barracuda - like more advanced threat management."

"While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics."

"Cloud Guard would be a complete solution if Check Point added a comprehensive data loss solution that included capabilities such as bulk data transfer detection."

"It's not fully integrated with Google Workspace, and the statistics don't update in real-time."

"During the East Coast server outage with Amazon service this week, mail was delivered and then pulled back because Harmony wasn't working properly and needed to scan it."

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

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

"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."

"The support is poor."

"The main disadvantages of Microsoft Purview Data Loss Prevention in comparison to the Netscope product are notable considerations."

"It could cover more solutions and technologies."

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

"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."

"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

Pricing and Cost Advice

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

"The prices are slightly expensive."

"The solution's pricing lacks transparency."

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

"The solution is not that expensive."

"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 pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"Reasonable cost, quick and easy implementation, and transparent."

"The pricing is competitive."

"This is a very good product if you are on the cloud, but the price is a little more expensive."

"The price is very good, based on what they deliver."

"The pricing is expensive."

"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."

"There are absolutely no additional costs to the standard licensing fees. One of the wonderful pieces is that CloudGuard SaaS is all-inclusive in its licensing. There's no a-la-carte functionality. You're getting 100 percent of the product for the licensing that you're paying."

"I'm in this business as a system integrator, so I need to suggest Check Point to some customers who are comparing products. I sell Check Point, Fortinet, and Palo Alto solutions. In terms of licensing, this solution is quite competitive but very costly. For someone looking at security as a primary concern, they should only invest in Check Point. For a customer who is looking at security combined with pricing, Check Point might not be the core solution for them. In today's market, customers are looking for effective security with efficient pricing, and Check Point is not suitable for these types of customers."

More Check Point Email Security (formerly Harmony Email & Collaboration) pricing and cost advice

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

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

"The pricing is reasonable."

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

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

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

"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."

"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."
