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

"This solution is easy to understand and easy to configure."
"The solution has different options that can be used to differentiate DDoS attacks."
"Clover is the best product globally."
"It will take the blow rather than our applications should an attack occur."
"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 Access is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare is simple to use."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"The stability of Microsoft Defender for Office 365 is fantastic."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"As a cloud-based product, it can scale well."
"Proofpoint Email Protection positively impacts my organization because it is a simpler solution in terms of user interaction compared to my previous email gateway, and its detection capabilities are considerably more advanced."
"Proofpoint Email Protection has positively impacted my organization by reducing the number of cyber email attacks we are receiving compared to the past."
"I have witnessed a positive impact of Proofpoint Email Protection on my organization, having worked for one of the world's largest organizations that uses Proofpoint consistently for email security."
"Proofpoint Email Protection has provided top shelf email protection services and has prevented breaches and loss of data."
"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."
"The setup was easy."
"The solution blocks malicious emails containing viruses and malware and reduces them out of spam."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"Operating and tuning the product is difficult."
"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."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The response time for support must be reduced."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Configuration requires going to a lot of places rather than just accessing one tab."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"I think Microsoft Defender for Office 365 can be improved by creating more educational pieces about not just looking for malware."
"The XDR dashboard has room for improvement."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"While it remains a difficult tool for spammers to crack, its limited automation lowers my rating to 7.5 out of 10."
"Pricing for the platform could still be cheaper."
"We find the cost to be prohibitive."
"Proofpoint is a little bit expensive."
"Sometimes it doesn't detect actual spam emails, and sometimes it catches normal emails."
"The incident reporting on offer needs to be improved. It's lacking right now. It should be on the platform somewhere."
"The solution could be improved with the addition of PLP and email encryption features."
"The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 solution's pricing lacks transparency."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"I know that the product is incredibly expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is very expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The license is expensive because the cost is based on the number of users."
"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."
"We sell annual licenses for this solution."
"In general, the pricing is competitive."
"It is expensive."
"The price is reasonable."
"The solution is expensive."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"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."

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!
