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.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.

Quotes from Members

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

Pros

"Cloudflare Access is part of the Zero Trust philosophy."
"It is a stable solution."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"I'm very satisfied with the environment and the dashboard."
"The blocking feature is very good."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"We like the content filtering and secure messaging features."
"It's good, it keeps the spam out, and it does a really good job at not allowing threats through."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The solution offers good technical support."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"It's good, it keeps the spam out."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"The Tap and Trap features. They are the best features."
"I recommend Proofpoint Email Protection because it provides everything in one place, such as security control."
"Proofpoint Email Protection has provided top shelf email protection services and has prevented breaches and loss of data."
"The anti-spam features are excellent on the email firewalls."
"Proofpoint Email Protection is very effective because they are very proactive, always ahead of the attackers, and were already detecting new kinds of attacks before customers thought about them."
"Proofpoint Email Protection's advantage is that, when it's working properly, it tends to catch more threats as compared to other products."
"Proofpoint Email Protection has positively impacted my organization because it has done its job; the company we support does not have any sort of vulnerability attacks by having it in place."
"The solution blocks malicious emails containing viruses and malware and reduces them out of spam."
 

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"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."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The initial onboarding was causing us some confusion."
"The onboarding process can be improved a little bit."
"The price could be better, it should be reduced."
"They could provide a unified licensing model, including all the security features."
"The detection rates are an area for improvement."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"The product's interface could be improved to be more user-friendly."
"Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere."
"The attachment scanning feature doesn't work properly."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"Proofpoint Email Protection is an expensive solution."
"Proofpoint Email Protection's interface is confusing and could be improved."
"Their technical support is mediocre. It could be better."
"However, for the cons, it requires continuous policy tuning to manage false positives. A Proofpoint Email Protection engineer requires continuous policy tuning to manage false positives, which is a disadvantage."
"I would want better spear phishing protection in the essentials package."
"The incident reporting on offer needs to be improved. It's lacking right now. It should be on the platform somewhere."
"I believe if the GUI were more user-friendly for people using it for the first time, or if there were more training available for end users to share with them, that would be good."
