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

"Cloudflare DDoS mitigates DDoS attacks."
"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."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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 is by far the most effective solution that I have come across."
"Cloudflare Access is a stable solution."
"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Microsoft Defender for Office 365 is a cloud-based email filtering service that helps protect our organization against unknown malware and viruses by providing robust zero-day protection and includes features to safeguard our organization from harmful links in real-time."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"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."
"Technical support is very good. They are knowledgeable and respond quickly."
"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 biggest ROI for us was when it stopped a ransomware attack, which could have cost us a ton of money and been detrimental to the company, so it basically paid for itself right there."
"The most valuable feature of Proofpoint Email Protection is the dashboards and their visibility, easy configuration, and artificial intelligence, and additionally, the reports are very important and helpful."
"The solution's technical support is good. I rate the technical support a ten out of ten."
"The initial implementation is pretty easy to handle."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"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."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"In terms of detection of spam, malware, and virus, the detection is 99.9% accurate."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"The GUI is sometimes slow to fetch the device report and could be improved."
"The product must provide better malware detection."
"The custom alerts have to improve a lot."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"I assess the stability and reliability of the solution as seven out of ten."
"There is room for improvement in terms of reporting."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Proofpoint Email Protection could improve the Mail Trace feature and make navigation easier."
"As a manager with multiple customers using Proofpoint Email Protection, having the ability to manage the admin console more efficiently would be beneficial."
"The flexibility of the solution can be improved."
"I rate the technical support at a 3 out of 10, with 10 being the best."
"I would like to see improvements in the transition from Proofpoint Protection Server to Proofpoint on Demand because Proofpoint Protection Server is not very user-friendly and requires logging into two portals for some features."
"Regarding improvements or enhancements in Proofpoint Email Protection, I find the platform somewhat chaotic. It has too many different sections that perform the same function, which is very confusing."
"Proofpoint Email Protection is an expensive solution."
"I think Proofpoint Email Protection could be slightly more intuitive."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"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."
"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 prices are slightly expensive."
"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."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"I know that the product is incredibly expensive."
"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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The pricing has become expensive."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"In general, 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 licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"The licensing is basically $8/user."

"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."

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!
