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

"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."
"It is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Enables me to work from two locations."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"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."
"Cloudflare Access is a stable solution."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"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."
"We chose Cisco Iron Port as it delivers strong email security protection and our company needed it to protect the company's email systems from spam, email viruses, .exe files, unwanted email from unwanted sender etc."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"Comparing Microsoft Defender and Cisco's Email Secure service, partners have noted that while Microsoft Defender offers email security, the tool's additional layer of protection provides further defense against threats like spam and phishing emails."
"This is a great product with wonderful support."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"Even though it's not perfect, it has the IMS engine, Intelligent Multi-Scan engine, and it does a good job, right out-of-the-box, of blocking the vast majority of things that should be blocked."
"Trend Micro constantly releases new versions and patches based on evolving needs."
"It is a good return on investments because I am a distributor selling this product to customers through a partner."
"Trend Micro Email Security is a great point and a great advantage for us."
"Trend Micro Email Security is a robust solution with quick performance. It works autonomously without the need for an administrator."
"The tool provides a strong defense against attacks. It is also easy to use. Trend Micro Email Security's integration capabilities are great."
"It is mostly stable."
"The technical support is good."
"Trend Micro Email Security [EOL] has positively impacted my organization as the digital user experience is good."
 

Cons

"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."
"Feedback could be enhanced."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The response time for support must be reduced."
"The initial onboarding was causing us some confusion."
"Our customers no longer use Cloudflare because its service is subpar."
"Cloudflare DDoS has poor technical support."
"I am not satisfied with the solution's reporting and logging."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"Added cost and delay to the network traffic, but performance did remain stable."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"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."
"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."
"While Trend Micro Email Security [EOL] is generally effective, there are occasional delays in adapting to very new or highly targeted phishing campaigns."
"The tool's dashboard is old."
"I wish Trend Micro Email Security [EOL] could improve by ensuring that if an attachment sent from an email is suspicious, it should be opened in another remote environment built by Trend Micro."
"One improvement for Trend Micro Email Security would be addressing services that sometimes stop during updates from the internet."
"The product must provide better customization features."
"I think customer support for Trend Micro Email Security [EOL] should be improved at some level."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"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 solution is not that expensive."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"The license was not per user, the license model was per feature. You could choose anti-virus, anti-spam, etc. It was feature-based and charged yearly."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"Cisco Secure Email is expensive, but we get what we pay for."
"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"It is a reasonably priced solution."
"The solution is inexpensive so we recommend it to small to mid-sized businesses."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"It's a VPN solution. Trend Micro is reasonably priced."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"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 solution's pricing is very optimum, given its quality, features, and stability."
"The tool must improve its pricing."
"Price-wise, it is a cheap solution. I rate the solution's pricing a one on a scale of one to ten, where ten is expensive. Annual payments are made for the licensing."
