Proofpoint Email Protection and Microsoft Defender for Office 365 are key players in the email security market. Proofpoint Email Protection may have the upper hand due to its robust anti-phishing capabilities and comprehensive protection.

Features: Proofpoint Email Protection is noted for its ability to block spam and phishing attacks, offers sandboxing, and has URL defense features. It also serves as a security gateway providing targeted attack protection. Microsoft Defender for Office 365 integrates seamlessly within the Microsoft ecosystem, offering real-time threat detection, strong anti-phishing capabilities, and security features across the Microsoft product suite.

Room for Improvement: Proofpoint Email Protection could improve its search capabilities, integration with complex environments, and enhance its administrative interface. Microsoft Defender for Office 365 can enhance scalability, technical support, and streamline its licensing models.

Ease of Deployment and Customer Service: Proofpoint Email Protection is deployed largely as a public cloud solution and is known for its responsive technical support, although users face challenges in accessing technical portals.

Which solution do you prefer: Microsoft Defender for Office 365 or Proofpoint Email Protection?

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.

Cobe Van Coller

Network Architect at IP Dimension

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.

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."

"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."

"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."

"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."

"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."

"There's room for improvement regarding the time frame for retrieving emails."

More Microsoft Defender for Office 365 cons

"I think Proofpoint Email Protection could be slightly more intuitive."

"Proofpoint Email Protection could improve the Mail Trace feature and make navigation easier."

"Every client always finds it expensive, but I don't know how much they're paying for it."

"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."

"The accessibility of Proofpoint Email Protection, particularly access to product trials, could be improved. It's hard to get a trial for Proofpoint Email Protection, and many customers prefer not just to do the POC or demo but try the product out."

"I have noticed some lagging and issues with the Proofpoint Protection Server, which is not the cloud solution or the Admin Portal solution. It seems to lag quite a lot when we try to work with folders, quarantine folders, or configure anything in there."

"Given my other experience with other vendors, I think they are a bit on the high end and a bit on the pricey end for the email security functionality that we were using."

"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. Sometimes it can block some of the information it shouldn't."

More Proofpoint Email Protection cons
