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.

Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

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.

Quotes from Members

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

Pros

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 simple to use."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS mitigates DDoS attacks."
"It is a stable solution."
"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."
"Cloudflare is by far the most effective solution that I have come across."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"Even though it's not perfect, it has the IMS engine, Intelligent Multi-Scan engine, and it does a good job, right out-of-the-box, of blocking the vast majority of things that should be blocked."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"There are a lot of filters for scam emails and things like that work out of the box. You can also use the antivirus features. I like its features."
"The solution is valuable if you are looking for a security email gateway that provides you with the most services possible."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"Proofpoint is number one in terms of market share worldwide, and we recommend it to clients because of its rich features in email protection, cloud protection, and backup targeted attack protection."
"Proofpoint Email Protection is a very robust solution."
"Using Proofpoint Email Protection has significantly improved SOC analyst workloads for my customers by enhancing response times and adding value through built-in threat investigation tools."
"Proofpoint Email Protection is the best solution from the perspective of email security."
"Proofpoint Email Protection offers an additional layer of protection compared to other brands like Microsoft, Mimecast, and Barracuda. While these major companies excel at detecting malicious attachments, the solution goes further by analyzing the context of emails, allowing for more nuanced decision-making."
"The most valuable features of Proofpoint Email Protection are the performance from being on the cloud."
"My advice to others is the solution seems to be good and stable with a very easy-to-use user interface."
"Proofpoint Email Protection's detection for true positives are great, false negatives or type two errors are very low, type one errors are acceptable and this capability is the one that allows the least amount of spam to enter."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"The user interface needs massive improvement. While the device works fine and it's not complicated to write policies, renaming menu items and showing policy flow in conjunction with the application could help."
"The product's GUI for the dashboard needs improvement."
"Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way."
"I am not satisfied with the solution's reporting and logging."
"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change."
"I would rate the stability a six out of ten. We had multiple issues with the stability."
"Scalability has certain shortcomings and needs to be improved because there are service providers who provide better scalability.v"
"As a manager with multiple customers using Proofpoint Email Protection, having the ability to manage the admin console more efficiently would be beneficial."
"I believe if the GUI were more user-friendly for people using it for the first time, or if there were more training available for end users to share with them, that would be good."
"The initial setup is complex."
"The solution could lower its price."
"Their technical support is mediocre. It could be better."
"The setup requires expertise. It needs someone with experience on managing it, and I would rate the implementation as needing someone experienced."
"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."
"Integration for reporting needs to be improved, it's a little complex."
 

Pricing and Cost Advice

"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 prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Cisco Secure Email is expensive, but we get what we pay for."
"In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"There were no other costs in addition to the standard licensing fees."
"Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
"The pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."
"The solution is expensive."
"Pricing depends on your environment and which model you want to buy."
"The price is reasonable."
"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."
"The solution uses a licensing model that is reasonable compared to other products."
"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."
"It is expensive."
"In general, the pricing is competitive."
"It is multiple times more expensive, which made it very much less attractive."
"We sell annual licenses for this solution."
