Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
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. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Bilal Saleem - PeerSpot reviewer
Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness
The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Quotes from Members

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

Pros

"Clover is the best product globally."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare is simple to use."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 mitigates DDoS attacks."
"The blocking feature is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"It can effectively monitor outbound and inbound devices."
"I find Trend Micro to be a good solution for security purposes."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"Trend Micro is a very good product."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"I like that it is very user-friendly and easy to install."
 

Cons

"The response time for support must be reduced."
"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 free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cloudflare DDoS has poor technical support."
"Lacks a VPN feature to provide a secure connection to the data center."
"The initial onboarding was causing us some confusion."
"Feedback could be enhanced."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
"Trend Micro's technical support has room for improvement."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
 

Pricing and Cost Advice

"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"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."
"We pay for an annual subscription for this email security solution."
"The solution's pricing is high, and I would rate it an eight out of ten."
"It's an expensive solution, and you may not see a return on investment in a short period of time. However, you will see a return over a long period of time."
"The price of Trend Micro Deep Discovery Email Inspector is less expensive than Microsoft solutions."
