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 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."
"Clover is the best product globally."
"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 will take the blow rather than our applications should an attack occur."
"Cloudflare Access is part of the Zero Trust philosophy."
"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."
"Cloudflare, in my opinion, was easy to implement."
"Cisco Secure Email is a budget-friendly solution."
"It is a user-friendly product."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number..."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"It does a good job of ensuring users are not compromised via email."
"The most valuable features of this solution are the antivirus, antispam, and integration with cloud services. This is a multifunctional solution."
"Trend Micro Email Security [EOL] has too much of an edge when comparing apple to apple; it is far better than other products."
"The most valuable feature of Trend Micro Email Security is the security level it provides. The solution is efficient."
"I find the anti-phishing and anti-spam features most valuable because they reduce false positives and enhance security."
"Since installing Trend Micro Email Security, it has significantly improved the overall security of my organization."
"Trend Vision One is one of the best XDRs that has been introduced to the market, with almost 14 applications integrated into a single console, including mobile device management, network security, endpoint security, and cloud app security, all with a really good GUI."
"The most valuable feature of Trend Micro Email Security is effective phishing prevention."
 

Cons

"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 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."
"Feedback could be enhanced."
"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."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"We use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"My opinion on the licensing of this solution is that it is a mess that needs sorting out. I am not particularly bothered by pricing as I administer it and make recommendations for people to buy or not to buy."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find."
"It takes time to harmonize information from the email log events with higher level reporting tools."
"The user interface of the Email Security Gateway should be improved."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"For improvement, the report part needs much improvement. It is a bit complex for some users."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"Trend Micro Email Security has integrated AI features recently, but the more the learning of their AI engines will yield much better results."
"There is room for improvement in mobile device management. The company also needs to work on pricing because it is quite costly compared to other products."
"The only negative thing about Trend Micro Email Security is its price. It could be less expensive."
"I think Trend Micro Email Security [EOL] could be improved by providing more DLP features, which I believe would be beneficial."
"The solution's configuration policy should be easier."
"In terms of email security, I would not rate Trend Micro as an expert solution."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"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 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."
"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."
"It is a super big router that costs a few hundred thousand dollars."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"Pricing depends on your environment and which model you want to buy."
"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."
"There were no other costs in addition to the standard licensing fees."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"The product's price falls on the higher side when compared to the other products on the market."
"In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
"The tool must improve its pricing."
"The cost is about $6,000 for 300 users for one year."
"Trend Micro Email Security's pricing is reasonable."
"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 price of Trend Micro Email Security is annual. There are no additional fees."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"It's a VPN solution. Trend Micro is reasonably priced."
"The price of Trend Micro Email Security is more than Sophos' similar solution."
