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

"The solution has different options that can be used to differentiate DDoS attacks."
"I'm very satisfied with the environment and the dashboard."
"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."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Access is a stable solution."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"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 risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"The initial setup was easy."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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."
"Using Proofpoint Email Protection has improved my SOC analyst workloads significantly by reducing false positives and the number of incidents in the queue."
"It is a very scalable solution."
"The solution scales quite well."
"I have witnessed a positive impact of Proofpoint Email Protection on my organization, having worked for one of the world's largest organizations that uses Proofpoint consistently for email security."
"Out of these three, no other email gateway can be compared with Proofpoint Email Protection."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"Proofpoint is much more advanced and capable of safeguarding the infrastructure and protecting the customer landscape, specifically from an email and attachment point of view, in day-to-day operations compared to these solutions."
 

Cons

"For the topic of improvement, providing some training material is one of my suggestions."
"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare DDoS has poor technical support."
"Operating and tuning the product is difficult."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"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."
"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."
"There is a different console for different things; I just want one consolidated console."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high."
"My experience with pricing, setup cost, and licensing for Proofpoint Email Protection is that it is somewhat on the higher end and more premium, but it is a good product."
"One major threat is QR code phishing, along with TOAD (Telephone-Oriented Attack Delivery). TOAD attacks don't include links, URLs, or attachments in emails. Instead, attackers try to trick you into calling them, often by offering something enticing like a 50% discount on football matches."
"The disadvantage of Proofpoint Email Protection in comparison to other competitors is its cost."
"Proofpoint Email Protection could improve by reducing the price."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"We'd like to have the ability to create more customized reports."
"Some of the old portal features of Proofpoint Email Protection are missing in the new portal, so some of the settings could be modernized."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The product is very expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"It's a user-base subscription."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"The solution is expensive."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"We sell annual licenses for this solution."
"The end customer is buying our solution, which can be for monthly or annual usage depending on our payment and business model."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."

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!
