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

"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."
"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."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Clover is the best product globally."
"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."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare is simple to use."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."
"It does a great job of preventing spam, malware, and ransomware."
"Administration of the email domains and custom filters are easily done via the web interface."
"It blocks bulk marketing messages, graymail, spam, and provides advanced malware protection."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"Since installing Trend Micro Email Security, it has significantly improved the overall security of my organization."
"The initial setup is not overly complex."
"Trend Micro Email Security [EOL] has positively impacted my organization by reducing email attacks and providing an understanding of how email attacks work."
"Trend Micro Email Security [EOL] provides visibility into email-based threats through reporting and alerting, which helps us identify attack trends and respond proactively."
"I find the anti-phishing and anti-spam features most valuable because they reduce false positives and enhance security."
"Trend Micro Email Security [EOL] has positively impacted my organization by helping to stop spam emails and identify malicious emails."
"We were able to reduce the time by 30% in terms of detection and response around 40%."
"The email and the signature based protection is the most valuable feature."
 

Cons

"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 software has automated alerts, but the automated alerts are not available in the mobile app."
"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 onboarding process can be improved a little bit."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our subscription plan for the solution has a limitation of bot signatures."
"Operating and tuning the product is difficult."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"One of the things that Cisco could improve on with IronPort is the support. Cisco doesn't really have enough engineers who have full, hands-on knowledge of IronPort. Knowledge of it is not something you can find easily compared to other security appliances."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"Scalability has certain shortcomings and needs to be improved because there are service providers who provide better scalability.v"
"They can do it better with web links, with the URLs."
"We cannot manage multiple devices from a single UI."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"In terms of email security, I would not rate Trend Micro as an expert solution."
"The solution does not check scam emails which is a critical need for our customers."
"The send box needs improvement to match other products."
"The solution's configuration policy should be easier."
"Trend Micro Email Security could improve by advancing its artificial intelligence in email security. There are rules that have to be configured. There should be less configuring."
"The product must provide better customization features."
"While Trend Micro Email Security [EOL] is generally effective, there are occasional delays in adapting to very new or highly targeted phishing campaigns."
"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 prices are slightly expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"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 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 product's price falls on the higher side when compared to the other products on the market."
"It is a reasonably priced solution."
"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."
"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."
"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."
"It is a relatively expensive option compared to other alternatives."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"It's a VPN solution. Trend Micro is reasonably priced."
"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 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."
"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."
"The solution is inexpensive so we recommend it to small to mid-sized businesses."
"The tool must improve its pricing."
"Trend Micro Email Security's pricing is reasonable."
"The cost is about $6,000 for 300 users for one year."
