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.

Advanced email protection has blocked targeted attacks and reduces manual threat handling
I feel Proofpoint Email Protection is overpriced. I cannot say that the security level being provided does not justify the cost, but when comparing the similar level of security with other applications or security systems, it is overpriced. If Proofpoint could provide offers or discounts for customers who are already using the product or for new customers implementing it, along with some free services or add-ons, that would be helpful in terms of financial expense. Proofpoint Email Protection has recently introduced AI functionality in terms of data security capabilities and protecting AI assistance from targeted attacks. This is important since everything is now related to AI. The solution is doing threat detection and real-time threat detection and response pretty well. There are a few things I would like to see improved. Sometimes Proofpoint Email Protection takes time to analyze the workflow and the nature of the email. In this age of AI, the solution should analyze an email on the first receipt and determine whether it should pass or be marked as spam without checking previous data. Another improvement would be to have a more user-friendly dashboard. Additionally, if Proofpoint could add the same features in BCP as part of email protection in BCP, it would be helpful since I currently have to take a different add-on for BCP, and integrating it would save costs. I cannot say that threats have increased or decreased with Proofpoint Email Protection because it depends on the mail flow. The solution captures and filters out all threats, and the email threats vary every day depending on how many users are receiving how many emails per day. Today there might be 1,000 emails, tomorrow 5,000, and the day after 500. Proofpoint Email Protection does its job by scanning all emails and threats are reduced to some extent. Since I am aware that virus definitions are updated every day, I cannot blame Proofpoint Email Protection if they take time to determine the nature of an email being received. There are sometimes emails that are false positives, and Proofpoint Email Protection is a bit strict in analyzing false positives, sometimes stopping emails that are actually required. It analyzes the previous nature of an email and if a template looks like an informational template or related to spam, it blocks it because it looks similar to one blocked earlier. However, the template might actually be required. If I receive the same template today that is also blocked by Proofpoint Email Protection, that particular template might be useful and should not be blocked. In such cases, I have to raise it as a false positive stating that this is something in use or my users use and should be released. When AI starts doing its work, it analyzes the email from a sender with a particular template and releases it, but if the same email and template come from another sender, it blocks it according to the policies.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

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

Pros

"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"The blocking feature is very good."
"Enables me to work from two locations."
"I'm very satisfied with the environment and the dashboard."
"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."
"The solution has different options that can be used to differentiate DDoS attacks."
"The solution offers very good flexibility. You can blacklist or whitelist with ease."
"The Tap and Trap features. They are the best features."
"Proofpoint Email Protection has positively impacted my organization by ensuring we are not at risk of a breach through email."
"We have noticed a huge improvement in productivity of the users by clearing up their inbox of malicious emails and spam, and it has also prevented and secured our environment on a daily basis, making the security team's job much easier."
"From a business perspective, the solution was very helpful as it speeded our business flow and increased email delivery."
"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."
"Using Proofpoint Email Protection has successfully reduced the volume of emails that we need to review."
"Our clients have definitely seen an ROI; their level of breach and reporting of malicious emails from their user base actually went down by over 50% by using this product."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"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."
"Cloudflare DDoS has poor technical support."
"Lacks a VPN feature to provide a secure connection to the data center."
"Operating and tuning the product is difficult."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The setup requires expertise. It needs someone with experience on managing it, and I would rate the implementation as needing someone experienced."
"There have been a few cases where an obvious phishing email has not been blocked, but perhaps Proofpoint Email Protection was still learning and needed some extra time to figure out that the email was malicious."
"The areas of Proofpoint Email Protection that could be improved or enhanced involve the email rewrite functionality. It can be aggressive sometimes, rewriting a lot of very benign content."
"The initial setup is complex."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"Proofpoint Email Protection does miss a lot of phishing attacks, and threat actors are using AI to create these phishing attacks."
"The solution can be expensive."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that 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 prices are slightly expensive."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Proofpoint is fairly expensive."
"I rate the price of Proofpoint Email Protection a four out of five."
"The licensing is basically $8/user."
"The solution uses a licensing model that is reasonable compared to other products."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"It is multiple times more expensive, which made it very much less attractive."
