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.

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.

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

"I'm very satisfied with the environment and the dashboard."

"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."

"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 blocking feature is very good."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"Cloudflare is by far the most effective solution that I have come across."

"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."

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

More Cloudflare One pros

"Since we have started using the solution, there have been fewer compromises."

"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."

"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."

"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."

"The two main features that prove most beneficial for us are URL scanning and attachment scanning."

"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."

"Microsoft Defender for Office 365's most valuable feature is its performance."

"Microsoft so far has been good; we haven't faced any kind of disruption or anything else, it's a good product and good platform, I must say, and overall it's a good product and good service and we haven't dealt with bugs or glitches."

More Microsoft Defender for Office 365 pros

"A lot of automation is present, and the quarantining of malicious emails and these processes are good and really help us in the investigation as well as the remediation part."

"It's a mature product. It does a good job in detection."

"When those bad emails are kept out of the gate, and the user can just focus on the email that matters most to them, I think that is how much Proofpoint Email Protection is impacting the entire organization."

"The anti-spam features are excellent on the email firewalls."

"Proofpoint Email Protection has improved operational efficiency, simplifying our internal processes and consolidating what used to be four or five different portals into a single, seamless login experience."

"Proofpoint Email Protection's initial installation is straightforward. It took us less than a day to complete the implementation."

"Proofpoint Email Protection has positively impacted my overall security posture, making it easier for users to encrypt files right in the portal and send them to customers, and it is simple for customers to access those files without difficulty."

"It is a very scalable solution."

More Proofpoint Email Protection pros

Cons

"The initial onboarding was causing us some confusion."

"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."

"The response time for support must be reduced."

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

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

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

"Feedback could be enhanced."

More Cloudflare One cons

"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."

"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."

"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats."

"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."

"The XDR dashboard has room for improvement."

"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."

"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."

More Microsoft Defender for Office 365 cons

"The false positives are an issue."

"The product's deployment is complex and requires technical knowledge."

"Phishing detection could improve further to match some of the capabilities offered by competitors."

"I have not noticed much change in operational efficiency after implementing Proofpoint Email Protection, but the process execution is light."

"While ingesting the logs into our SIEM tool, most organizations don't have the capability to buy the email gateway as it is quite an expensive one."

"Pricing for the platform could still be cheaper."

"Integration for reporting needs to be improved, it's a little complex."

"The only downside with Proofpoint Email Protection is the cost."

More Proofpoint Email Protection cons

"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."

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

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.

Whichever solution you choose, make sure that managed email security meets all of your requirements!
