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 protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Centralized protection has transformed email security and incident investigations by reducing false positives and improving behavioral threat detection
The challenges include the challenge of finalizing a product that has all the security features or capabilities that are usually required. For example, if there is an EDR platform that's just monitoring IDS signatures, it won't be as beneficial as one with behavioral monitoring and other critical aspects required according to the best practices of the industry. Additionally, if there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team. These challenges consist of managing multiple teams and products. Trend Micro Email Security comes in and solves these problems.Trend Micro Email Security is generally a bit more difficult to implement compared to the rest of the solutions such as network security modules or EDR modules, which are much easier. Trend Micro Email Security has some complexities in implementation, but there aren't any significant shortcomings that require Trend Micro to improve.

Quotes from Members

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

Pros

"Cloudflare is simple to use."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare Access is part of the Zero Trust philosophy."
"It is a stable solution."
"I'm very satisfied with the environment and the dashboard."
"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."
"Cisco Secure Email's most valuable is email certification."
"The most valuable features of the Cisco ESA have to do with the intelligence they provide us, as they respond quickly to any phishing attacks and threats on the system."
"It is a user-friendly product."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"At one point, there was a zero-day attack. The Cisco appliance detected it and stopped it, helping us out. We avoided the attack and potential damage."
"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"The email and the signature based protection is the most valuable feature."
"The integration capability of the solution is good."
"I have seen a huge decrease in phishing emails and spam being received by end users, with about 80% of observed spam and phishing emails being reduced."
"Trend Micro Email Security [EOL] has positively impacted my organization by helping to stop spam emails and identify malicious emails."
"Since installing Trend Micro Email Security, it has significantly improved the overall security of my organization."
"Based on my past experience, the accuracy and reliability of Trend Micro Email Security [EOL]'s output demonstrate very minimal false positive detections, with many detections being very accurate and the AI and machine learning working perfectly, complemented by traditional signature behaviors, leading to a high detection rate and accuracy when compared to other competitor products."
"Trend Micro is better than any of its competitors."
"The most valuable feature of Trend Micro Email Security is effective phishing prevention."
 

Cons

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"The onboarding process can be improved a little bit."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"Feedback could be enhanced."
"I would like to see features like AI since it is currently an area that the product lacks."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user."
"Licensing is quite complicated for a number of customers, including ourselves."
"That's why I wouldn't give it anywhere near a perfect score, because the artificial intelligence just isn't there yet."
"The reporting functionality needs to be improved."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The management interface of Trend Micro Email Security [EOL] looks a bit more legacy, and it can have a little bit more improvements in terms of modernizing the UI."
"The only negative thing about Trend Micro Email Security is its price. It could be less expensive."
"Trend Micro Email Security should introduce new features, improvements, and updates which are cost-effective and easy to deploy."
"There is a limitation when customers are using their email from a third-party solution that isn't from Trend Micro."
"There needs to be more documentation for the product."
"The areas of Trend Micro Email Security [EOL] that could be improved or enhanced are the reporting side."
"Trend Micro Email Security has integrated AI features recently, but the more the learning of their AI engines will yield much better results."
"I think when incidents occur with Trend Micro Email Security [EOL], the support should be a bit faster with response times."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."

"The solution is expensive."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."

"The price of Trend Micro Email Security is annual. There are no additional fees."
"The price of Trend Micro Email Security is more than Sophos' similar solution."
"The solution's pricing is very optimum, given its quality, features, and stability."
"It's a VPN solution. Trend Micro is reasonably priced."
"It is expensive. The cost is per box, and it depends on how big your environment is. Prices range from 11 to 12 dollars for licenses and can fluctuate up and down, but for environments with 4,000 to 5,000 users, it can be between 6 to 8 dollars."
"The cost is about $6,000 for 300 users for one year."
