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.

Q&A Highlights

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.

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.

Quotes from Members

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

Pros

"It will take the blow rather than our applications should an attack occur."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"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 capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"The blocking feature is very good."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"It is a stable solution."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

More Cloudflare One pros

"The deployment capability is a great feature."

"It’s easy to handle integrations, and we don't need a lot of people in our IT team."

"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."

"With Defender for Office 365, we have been able to increase the security posture across our organization."

"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."

"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 definitely is a must for email protection and O365 app DLP, and combined with Microsoft Defender for Endpoint, Microsoft Defender for Identity, and MCAS, it provides a holistic solution for threat protection, email protection, O365 apps protection, and DLP for both internal and external risks."

"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."

More Microsoft Defender for Office 365 pros

"Overall, we've been happy with the product and the results we've gotten."

"The most valuable feature is the option to edit the inbound security."

"The most valuable features of Proofpoint Email Protection are the performance from being on the cloud."

"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."

"Since I started using Proofpoint Email Protection, I have blocked numerous phishing emails, and while I cannot remember the exact numbers, it is more than 200 or 300."

"The most valuable features are the business email compromise protection and targeted attack prevention."

"Proofpoint Email Protection is quite scalable; I have not experienced any issues with the onboarding and offboarding of users and devices."

"Its main defense is to stop malicious emails from coming through. There is a sandbox environment where you can open malicious or suspicious emails to make sure that they're not malicious, instead of taking the risk of having your employees do it. This is definitely something that everybody needs nowadays, especially with the rise in cyber attacks."

More Proofpoint Email Protection pros

Cons

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

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

"The onboarding process can be improved a little bit."

"Feedback could be enhanced."

"Our customers no longer use Cloudflare because its service is subpar."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"For the topic of improvement, providing some training material is one of my suggestions."

"Operating and tuning the product is difficult."

More Cloudflare One cons

"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."

"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. If they could include that file part in the report, without my having to go to the device itself, that would help."

"Its price should be improved. Its cost is a major concern for us."

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

"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."

"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."

"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."

"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."

More Microsoft Defender for Office 365 cons

"We have some use cases that haven't been dealt with yet, so that could be improved."

"While Proofpoint is better, I find Abnormal to be much more effective because it uses an advanced AI engine to detect email spams and phishing."

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

"Proofpoint is a little bit expensive."

"The false positives are an issue."

"I believe they still need to improve by consolidating some portals, as currently, you have to log in separately to a few of them."

"Pricing for the platform could still be cheaper."

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

More Proofpoint Email Protection cons

Pricing and Cost Advice

"The solution is not that expensive."

"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."

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

"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's pricing lacks transparency."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"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."

"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."

"The license is expensive because the cost is based on the number of users."

"I know that the product is incredibly expensive."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."

More Microsoft Defender for Office 365 pricing and cost advice

"It is expensive."

"The tool's pricing depends on the customer's preference, offering options for an annual license or a monthly subscription. The cost varies based on factors such as the number of users and specific requirements. Overall, the pricing is competitive."

"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."

"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."

"The solution uses a licensing model that is reasonable compared to other products."

"The licensing is basically $8/user."

"It is multiple times more expensive, which made it very much less attractive."

"Proofpoint Email Protection has comparable pricing."

If you're looking for Managed Email Security, it can be hard to decide between Microsoft Defender for Office 365 and Proofpoint Email Protection.
