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 protection has blocked targeted attacks and reduces manual threat handling
I feel Proofpoint Email Protection is overpriced. I cannot say that the security level being provided does not justify the cost, but when comparing the similar level of security with other applications or security systems, it is overpriced. If Proofpoint could provide offers or discounts for customers who are already using the product or for new customers implementing it, along with some free services or add-ons, that would be helpful in terms of financial expense. Proofpoint Email Protection has recently introduced AI functionality in terms of data security capabilities and protecting AI assistance from targeted attacks. This is important since everything is now related to AI. The solution is doing threat detection and real-time threat detection and response pretty well. There are a few things I would like to see improved. Sometimes Proofpoint Email Protection takes time to analyze the workflow and the nature of the email. In this age of AI, the solution should analyze an email on the first receipt and determine whether it should pass or be marked as spam without checking previous data. Another improvement would be to have a more user-friendly dashboard. Additionally, if Proofpoint could add the same features in BCP as part of email protection in BCP, it would be helpful since I currently have to take a different add-on for BCP, and integrating it would save costs. I cannot say that threats have increased or decreased with Proofpoint Email Protection because it depends on the mail flow. The solution captures and filters out all threats, and the email threats vary every day depending on how many users are receiving how many emails per day. Today there might be 1,000 emails, tomorrow 5,000, and the day after 500. Proofpoint Email Protection does its job by scanning all emails and threats are reduced to some extent. Since I am aware that virus definitions are updated every day, I cannot blame Proofpoint Email Protection if they take time to determine the nature of an email being received. There are sometimes emails that are false positives, and Proofpoint Email Protection is a bit strict in analyzing false positives, sometimes stopping emails that are actually required. It analyzes the previous nature of an email and if a template looks like an informational template or related to spam, it blocks it because it looks similar to one blocked earlier. However, the template might actually be required. If I receive the same template today that is also blocked by Proofpoint Email Protection, that particular template might be useful and should not be blocked. In such cases, I have to raise it as a false positive stating that this is something in use or my users use and should be released. When AI starts doing its work, it analyzes the email from a sender with a particular template and releases it, but if the same email and template come from another sender, it blocks it according to the policies.

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft Defender for Office 365 should be more proactive."
"Sometimes it detects false positives."
"The stability and UI are the two areas of the solution with certain shortcomings that need improvement."
"Pricing for the platform could still be cheaper."
"I feel Proofpoint Email Protection is overpriced. I cannot say that the security level being provided does not justify the cost, but when comparing the similar level of security with other applications or security systems, it is overpriced."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"The email DLP portion could be a bit easier."
"The solution could be improved with the addition of PLP and email encryption features."
"Unfortunately, the whole product is going downhill right now, ever since they were sold to Thoma Bravo. We're constantly having problems with stability and the product in general."

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!
