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 effectively detects a wide range of threats and improves productivity

Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. 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. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.

Protects sensitive data across devices and helps address client compliance needs proactively

The reporting in Microsoft Purview Data Loss Prevention is a little easier than most Microsoft portals. I understand the licensing cost, especially if you're a Business Premium or in the SMB world, and a lot of clients run with a Business Premium. That comes with data loss prevention in a manual process, whereas E5 gives automation. Microsoft has said, 'Okay, here's your Microsoft 365 E5 compliance add-on that can go on the Business Premium.' So Business Premium users can get the data loss prevention features of E5, which is fantastic. That was the big point that they were missing, and I'm glad that they actually have an add-on now that makes it possible. So truly, I don't think there's a downside. Maybe more reporting, but that's it.

Quotes from Members

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

Pros

"Cloudflare is by far the most effective solution that I have come across."

"Enables me to work from two locations."

"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."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

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

"This solution is easy to understand and easy to configure."

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

More Cloudflare One pros

"For us, I prefer Check Point before Palo Alto and before other brands because Check Point is most effective in attack mitigation and attack detection."

"As a comprehensive solution, Check Point offers a very granular and best-in-class experience."

"Machine Learning and AI for email security have helped all the organization's members to guard their information against insecure exposure."

"Based on domain and URL reputation, it will allow traffic to flow."

"It helped us to bring security compliance and ensure system robustness throughout."

"As with most of the other Check Point products, the CloudGuard SaaS has the advanced visibility of the events and alerts."

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

"The most valuable feature of the solution is the phishing protection it offers."

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

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

"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."

"The auto-labeling feature is definitely the most valuable feature, as it goes in and labels the documents for you in different repositories, covering the Outlook and Exchange repositories along with SharePoint and OneDrive, which is really helpful in those areas."

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

"The product has improved compliance and confidence. We are aware of the data that is leaving our organization. It provides confidence in data management and information storage."

"Microsoft Purview Data Loss Prevention makes it way easier to prevent unauthorized sharing of sensitive information within the organization."

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

"Microsoft Purview Data Loss Prevention prevents users from sharing sensitive information outside the organization based on the configurations that we've implemented."

More Microsoft Purview Data Loss Prevention pros

Cons

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

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

"I would like them to include a VPN feature to provide a secure connection to the data center."

"The initial onboarding was causing us some confusion."

"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."

"Operating and tuning the product is difficult."

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

More Cloudflare One cons

"We have only encountered some false positives that required us to whitelist certain third-party domains, mostly due to their poor email configuration preventing DMARC or SPF alerts."

"The documentation is a little unintuitive, and I make an additional effort for the first deployment."

"We still get some false positives. There are times when legitimate stuff gets flagged and it could be that somebody is expecting a very important email but they don't end up getting it. On the flip side, when we alert Check Point about stuff like this, it is corrected, so they are improving. That's a plus."

"For tech people who want to dive deep into self-servicing capabilities, Check Point could improve in this area."

"At this time, the two-factor authentication does not work for Active Directory."

"Other vendor support teams go after fixing the issue the moment that they join the remote session. The problem that I have faced with Check Point support is that they share the case number with me, then it takes at least two days for them to join a remote session with us, even though we have asked for this timeframe to change. Even though we have already explained the problems that we are facing or the business pain points in our network on the call or email, we have to repeat the problem statements again in the console. It can take four or five days to resolve the issue from the moment they understand the problem. This includes the time to teach their R&D or internal team whatever the issue is. I have faced timeframes as long as seven to 10 days for fixing some issues."

"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."

"The business team should be further expanded, and more peer feedback should be made available publicly to have better and complete visibility of the application globally."

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

"There is no AIP for Linux systems. That's a setback. Another thing it's lacking is libraries to work with Python. It has libraries for C# and C++, for example, but not for Python and, these days, Python is very useful."

"I rate the overall solution 3 out of 10."

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

"Technical support is awful."

"The AI advancements can improve the false positives."

"I would assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect."

"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."

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

More Microsoft Purview Data Loss Prevention cons

Pricing and Cost Advice

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

"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's pricing lacks transparency."

"The prices are slightly expensive."

"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."

"Being able to keep the phishing campaigns out of my company has been ROI for me."

"The product is expensive compared to some competitors, especially for the SME segment."

"I rate the platform’s pricing a seven and a half."

"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."

"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."

"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."

"The pricing is competitive."

"Having information stolen by a hacker would be more expensive than purchasing a license."

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

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

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

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

"Though I am not a specialist, the tool is quite expensive."

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