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.

Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

Quotes from Members

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

Pros

"It will take the blow rather than our applications should an attack occur."
"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."
"It is a stable solution."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare Access is a stable solution."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare is simple to use."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"Checkpoint Harmony Email and Collaboration has significantly improved our email security by effectively blocking phishing, malware and ransomware threats."
"After the implementation of the solution, email phishing is stopped and gives complete visibility."
"It helped us to bring security compliance and ensure system robustness throughout."
"Getting reports and finding threats in the console is easy."
"The automated rule cleanups and automated policy installs have improved my customers' organizations."
"This product enhances faster and more secure sharing of information among colleagues from different departments."
"Machine Learning and AI for email security have helped all the organization's members to guard their information against insecure exposure."
"I recommend Check Point Harmony Email and Collaboration to all types of companies, from small businesses to enterprises."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."
"If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection."
"The solution is stable."
"It has an efficient email filtering feature."
"It's very easy to deploy and configure."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The initial onboarding was causing us some confusion."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"They don't have a person to provide support for customers using the solution under their free plan."
"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 free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"Cloudflare DDoS has poor technical support."
"We understand that false positives are always there, but sometimes the notifications are more than expected."
"After updates, the internet connection fails, and I have to restart my desktop to resume initial functionalities."
"There is always room for improvement and growth."
"The solution fails to support hybrid deployments."
"For tech people who want to dive deep into self-servicing capabilities, Check Point could improve in this area."
"A signature-based filter could improve the solution's AI model for spam email."
"They could continue to offer more stringent security policy measures for threat point management."
"I would like the agents to perform better; sometimes, they are too heavy for endpoints, and they affect performance."
"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"The physical appliance has been discontinued, although the platform still exists."
"The pricing could always be better."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The pricing could always be better."
"This solution could be improved by integration with Sandbox."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
 

Pricing and Cost Advice

"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."
"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."
"The prices are slightly expensive."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"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 rate the product's pricing a five on a scale of one to ten, where one is cheap, and ten is expensive."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"The pricing is expensive."
"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."
"The product is expensive compared to some competitors, especially for the SME segment."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
