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.

Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Advanced email defenses have protected healthcare staff and simplified incident response
There are many things that could be improved, but once you are very well-known about this application, you could perform that improvement plan. There are many scenarios where I have worked with Proofpoint Email Protection where a requirement was not fulfilled due to the limitation of the product. For example, we have Report Phish automation. With Proofpoint Email Protection, we can configure Report Phish and forward the email to any email addresses or shared mailboxes that we provide in the configuration. That email is forwarded as is with whatever the user reports as a phishing email. However, some organizations do not want the reported phishing email to go as is into their ticketing tool because it might contain malicious attachments and malicious links that are not required to go into their internal organization. Proofpoint Email Protection has that limitation. They cannot forward or restrict, but could forward only limited information such as some header information, sender subject details, or only limited information. As it is, the email can be forwarded, not as limited information. Proofpoint TRAP solution also has limitations. It cannot create alert notifications for some specific requirements because Proofpoint works the way it is designed, and if you want it to work based on our requirement, that should not be possible. There is a scope of limitations here. There are many improvements that should be made. First, they should work on their false positive minimization. Proofpoint generally takes all emails, investigates them, and classifies them. There are many situations where legit emails are blocked because that domain is found to be under a malicious category somehow, but actually it is not. False positive minimization could be improved, and they could enhance their other applications or solutions. There are many things that they could improve from each application and each portal.

Quotes from Members

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

Pros

"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."
"The solution has different options that can be used to differentiate DDoS attacks."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare DDoS mitigates DDoS attacks."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"Enables me to work from two locations."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The ability to respond to threats if very important."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"Microsoft Defender for Office 365 is a stable solution."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"Provides better control over emails, especially those sent via Office 365 on the cloud."
"Overall, it is a good product, providing everything in a single dashboard where we can find all the information related to the risks involved within a suspicious email."
"The most valuable feature of Proofpoint Email Protection is the blocking capabilities, it blocks a lot of potential threats."
"Proofpoint is the main tool for blocking spam because it denies the connection altogether."
"It has been comprehensive and easy to use for both users and administrators."
"The solution blocks malicious emails containing viruses and malware and reduces them out of spam."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"When I manage a SOC and Proofpoint Email Protection is integrated with it, it gives me a consolidated alert, so when phishing alerts come in it is slightly easier to manage, even my L1 incident response team from the SOC can easily understand the alerts, perform basic checks on VirusTotal, and create complete SOAR automation from that information."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Our customers no longer use Cloudflare because its service is subpar."
"Operating and tuning the product is difficult."
"The response time for support must be reduced."
"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."
"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."
"In one of the reports, I can get the exact place where a vulnerable file resides, but for that, I need to explicitly go into the device and check."
"The custom alerts have to improve a lot."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"It is not up to the mark in comparison with Wiz or Palo Alto."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"The price could be improved."
"Regarding improvements or enhancements in Proofpoint Email Protection, I find the platform somewhat chaotic. It has too many different sections that perform the same function, which is very confusing."
"The setup requires expertise. It needs someone with experience on managing it, and I would rate the implementation as needing someone experienced."
"The initial setup is complex."
"Proofpoint Email Protection could improve on the training. Every organization is different and to fine-tune it to block everything properly there needs to be better training."
"For Proofpoint Email Protection, when it comes to support, there are times when they do not meet the SLAs for support, mostly on Fridays."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"However, for low-size or mid-level organizations, it can be challenging in terms of cost, management, and resource utilization, which could be a problem for low-level enterprises."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The license is expensive because the cost is based on the number of users."
"The pricing is normal. Considering its popularity, it's not overpriced."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"It's a user-base subscription."
"The product is expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The solution is expensive."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"Proofpoint Email Protection has comparable pricing."
"Pricing has recently been increased and the cost is a downside"
"The solution uses a licensing model that is reasonable compared to other products."
"It is on a yearly basis. Their floor for SMB doesn't matter. The user count is 100 users and below at $2,500 a year. Its cost is higher than other solutions. It is probably about 20% to 30% higher than what you would get with Microsoft. There are no additional costs. All costs are factored in. It can be improved pricing-wise so that it is affordable for the SMB market."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"We sell annual licenses for this solution."

In my opinion, there is little comparison. Proofpoint is an industry leader in email protection and has a very tightly integrated ecosystem for email defense, incident response, and awareness training. They have dedicated teams monitoring the threat landscape and continually tweak their algorithms to match current threats. Proofpoint goes far beyond email protection with tools to help your team investigate email-related threats, monitor user interactions and risks, act on users who continually handle email improperly with training, simulated phishes for user awareness, and even tools to reach full DMARC and DKIM protection (which can be extremely time and labor intensive). Defender has very little footprint, but also offers far less features. Proofpoint can be a more costly solution, but when compared feature for feature it far outweighs Defender. We do use both at my organization and I rarely interact with Defender as part of email investigations. Both will offer great protection, but beyond that Proofpoint is very feature rich and gives my team more tools to combat email threats when something is not caught by the gateway rules. Quite often emails do not contain threats prior to delivery and are weaponized afterward to get past the email defenses. Proofpoint has TAP and TRAP to isolate and remove those threats once they do become weaponized; along with the intelligence to know it has occurred. Proofpoint also has stellar reporting features so you have a very good understanding of your email environment at a glance.

If you're looking for Managed Email Security, it can be hard to decide between Microsoft Defender for Office 365 and Proofpoint Email Protection. It's like choosing between two delicious flavors of ice cream — both are good, but what flavor do you prefer? Microsoft Defender for Office 365 is managed by Microsoft’s Security & Compliance Center and provides managed email security for Office 365 customers. It offers comprehensive protection against malicious emails, phishing attacks, and other advanced threats. On the other hand, Proofpoint Email Protection is managed by a third-party provider and provides managed email security for businesses of all sizes. While it doesn't have as many features as Defender, Proofpoint still offers robust protection against malicious emails, phishing attacks, and other advanced threats. In the end, it comes down to personal preference. Do you prefer managed email security managed by Microsoft or a third party? It all depends on your individual needs. Whichever solution you choose, make sure that managed email security meets all of your requirements!
