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

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"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."
"It will take the blow rather than our applications should an attack occur."
"It is a stable solution."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Access is part of the Zero Trust philosophy."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"The product is not resource-intensive."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
"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 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"There are several features that I consider valuable."
"We have seen a return on investment because if we would have received a phishing email, Microsoft Defender for Office 365 would help out to detect the threat instead of crashing down the whole company."
"Proofpoint Email Protection helped create a safe environment by blocking and preventing Active Directory harvesting attacks, imposter attacks, backscattering, spam, and malicious attacks."
"My advice to others is the solution seems to be good and stable with a very easy-to-use user interface."
"The most valuable feature is the option to edit the inbound security."
"From the reports that we hear back from clients regarding Proofpoint Email Protection, they are noticing less spam and fewer phishing attempts in their email."
"Proofpoint Email Protection ensures users have clean mailboxes and are not bothered by unwanted email."
"The solution is very user-friendly."
"Proofpoint Email Protection is very effective because they are very proactive, always ahead of the attackers, and were already detecting new kinds of attacks before customers thought about them."
"Overall, using Proofpoint Email Protection has positively impacted our security posture, and we are using multiple products in Proofpoint, including DLP and email protection, and the real-time experience has us very satisfied."
 

Cons

"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 free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Operating and tuning the product is difficult."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The initial onboarding was causing us some confusion."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Feedback could be enhanced."
"Our customers no longer use Cloudflare because its service is subpar."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"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 is a different console for different things; I just want one consolidated console."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"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."
"We are waiting for better software to block viruses."
"There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types."
"The only limitation we have with Proofpoint Email Protection is when we implement it with Google Workspace."
"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."
"However, for low-size or mid-level organizations, it can be challenging in terms of cost, management, and resource utilization, which could be a problem for low-level enterprises."
"The false positives are an issue."
"I would want better spear phishing protection in the essentials package."
"The reporting section could be enhanced. I like some reports but if they could allow us to create custom reports with more flexibility it would enhance the reports more."
"Proofpoint has a lot of false alarms."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
 

Pricing and Cost Advice

"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."
"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 solution is not that expensive."
"The solution's pricing lacks transparency."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"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 license is expensive because the cost is based on the number of users."
"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."
"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 pricing has become expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The price is reasonable."
"We sell annual licenses for this solution."
"The licensing is basically $8/user."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"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."
"I rate the price of Proofpoint Email Protection a four out of five."
"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."
"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."

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!
