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.

Zero trust access has transformed remote connectivity and now simplifies secure app usage

Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.

"What I find most valuable in Zscaler Private Access is that it's a VPN, and its connectivity as a VPN is its most valuable feature."

"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."

"The most valuable features of Zscaler SASE include web filtering, application control, and the private access configuration."

"This is a product that I recommend for anybody who wants a scalable, cloud-based solution."

"The initial setup is easy."

"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."

"Subsequently, after this, there is a huge reduction, as the vulnerabilities, especially the security bugs that were coming prior to Zscaler Zero Trust Exchange Platform, were about 20,000 to 22,000 and have come down more than 40 percent, which is definitely an advantage over the previous product."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."

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

"Operating and tuning the product is difficult."

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

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

"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."

"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."

"I chose nine because I'm not quite sure anything is a ten; I don't really know how to answer that, but the ten leaves room for improvement."

"The reporting could be improved."

"We have used technical support, but their response time is very slow. It needs to be improved."

"Sometimes junior staff members would ask scripted questions without having enough knowledge to address the core issue immediately."

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

"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."

"It's an expensive solution."

"There is some issue while accessing the portal. It takes too long."

"There could be more DLP-related features. Additionally, there needs to be flexibility for integrating ISP features."

"The product is not reliable."

"It would be better if the Zscaler Private Access team made it easier for people to find subscriptions on the portal, mainly information on what my customers subscribed to or the type of licenses purchased."

"Occasionally, there are certain delays in report generation."

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

More Zscaler Zero Trust Exchange Platform cons

Pricing and Cost Advice

"The solution's pricing lacks transparency."

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

"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."

"The prices are slightly expensive."

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

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

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

"Check Point is more expensive. That's the honest truth. So far, it's a good value for the money."

"The pricing is expensive."
