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.

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

"The blocking feature is very good."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"Cloudflare Access is part of the Zero Trust philosophy."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The stability of Microsoft Defender for Office 365 is fantastic."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"Since we have started using the solution, there have been fewer compromises."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"With Defender for Office 365, we have been able to increase the security posture across our organization."
"Proofpoint Email Protection has positively impacted my organization by advancing our email security posture."
"Before deploying Proofpoint Email Protection, we were frequently attacked by phishing and DDoS, and after deploying it, attacks have been reduced by up to 80 percent and phishing has been completely eliminated, so it is working very efficiently."
"The most valuable feature of this solution is that it's a one-stop shop for email protection."
"Out of these three, no other email gateway can be compared with Proofpoint Email Protection."
"Proofpoint Email Protection offers an additional layer of protection compared to other brands like Microsoft, Mimecast, and Barracuda. While these major companies excel at detecting malicious attachments, the solution goes further by analyzing the context of emails, allowing for more nuanced decision-making."
"It has been comprehensive and easy to use for both users and administrators."
"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"The stability is good; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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 response time for support must be reduced."
"Operating and tuning the product is difficult."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"I assess the stability and reliability of the solution as seven out of ten."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"This is quite an expensive solution and understanding the pricing model and features is quite complicated and it can, in fact, be a nightmare when dealing with Microsoft."
"You should be able to deploy Defender for every subscription without the need to add servers."
"We'd like to have the ability to create more customized reports."
"Proofpoint Email Protection has a new approach to email security with its API feature. Currently, it only works with Office 365. In the future, it would be beneficial if it also works with Gmail, as Check Point is currently the only brand that has API email security for Gmail. It would be beneficial if Proofpoint Email Protection could add this integration, they would be more competitive with other vendors."
"Proofpoint is a little bit expensive."
"Some of the old portal features of Proofpoint Email Protection are missing in the new portal, so some of the settings could be modernized."
"The solution can be expensive."
"As far as visibility goes, it is definitely attainable, but additional appliances must be purchased for Proofpoint. I would rate visibility at approximately 50 to 60 percent."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"The false positives are an issue."

"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."

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!
