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

"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."
"The blocking feature is very good."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"I would rate Mimecast Email Security a nine out of ten."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"We like the content filtering and secure messaging features."
"The initial setup is very straightforward."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"The solution is stable and reliable. There are no bugs or glitches, and it doesn't crash or freeze."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"Using Proofpoint Email Protection definitely helps with reducing the SOC Analyst workloads."
"Proofpoint Email Protection's initial installation is straightforward. It took us less than a day to complete the implementation."
"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"The Tap and Trap features. They are the best features."
"It's detection of true positives are great, as it's cloud based it's very scalable and stable."
"Out of these three, no other email gateway can be compared with Proofpoint Email Protection."
 

Cons

"The response time for support must be reduced."
"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 initial onboarding was causing us some confusion."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The onboarding process can be improved a little bit."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"Operating and tuning the product is difficult."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"They could provide a unified licensing model, including all the security features."
"The differentiation between bulk spam mail and campaign-related mail could be improved."
"Its pricing can be improved. It is a bit expensive."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The solution is expensive in comparison to similar solutions."
"The price could be better, it should be reduced."
"As a user, the user interface of the management console could be upgraded, for example."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"I want Security Awareness Training in there as a package deal. A lot of companies are starting to value email security a little bit more and take it a little bit more seriously, and the great product that we link together with a lot of these sales is a training product called Security Awareness Training. It is an upsell that we do with Proofpoint, and it is definitely something that I recommend everybody with email security to look into. It would be great if Security Awareness Training is included with the email security."
"The solution's server console and cluster dashboard have been the same for four years so need to be upgraded."
"One major threat is QR code phishing, along with TOAD (Telephone-Oriented Attack Delivery). TOAD attacks don't include links, URLs, or attachments in emails. Instead, attackers try to trick you into calling them, often by offering something enticing like a 50% discount on football matches."
"I would like to see improvements in the transition from Proofpoint Protection Server to Proofpoint on Demand because Proofpoint Protection Server is not very user-friendly and requires logging into two portals for some features."
"The support team was a bit slow."
"The false positives are an issue."
"My experience with pricing, setup cost, and licensing for Proofpoint Email Protection is that it is somewhat on the higher end and more premium, but it is a good product."
"The solution should add post-sales training."
