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.

Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

Stronger email and mobile security has protected users from ransomware and simplified management
Price is obviously a challenging part, and I think it is the biggest problem we have suffered from over the last two or three years due to a 7 to 8% hike per year, twice a year, which is why we have some renewals on Sophos Email, Sophos XDR, EDR, and the firewall, but due to price hike, they are unable to renew it. The price is going to be very high. It would be better if Sophos can provide a more flexible pricing model for different types of businesses. Price could be lower. The main competitor for Sophos in the market is Palo Alto, which has reduced their price by more than 35 to 40%, making it a very challenging part to sell this product. Palo Alto provides the same functionality for email security, which adds to the challenge because the price is going very high.

Quotes from Members

Pros

"It will take the blow rather than our applications should an attack occur."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Cloudflare is by far the most effective solution that I have come across."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"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."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"With both of them working together, we have the perfect solution for mail."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The anti-spam functionality of Sophos Email is good."
"Endpoint and server protection are very effective."
"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."
"It filtered most of the spam and junk emails and quarantined them."
"You will find a lot of value in this solution and the small difference in price should not matter, it does protect well."
"Sophos Email is a stable solution."
"The tool is a good solution for protecting against email attacks and monitoring networks. It supports our compliance efforts and is easy to use and stable."
"The most valuable feature of Sophos Email is the sandbox. We're able to scan the file, isolate it, and look at it before it is delivered. It is highly effective."
 

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Feedback could be enhanced."
"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."
"The initial onboarding was causing us some confusion."
"For the topic of improvement, providing some training material is one of my suggestions."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"The solution is not 100 percent stable and that can use improvement."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"The solution is not 100 percent stable and that can use improvement."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"The security of the solution could improve."
"There have been some issues with compatibility and effectiveness, particularly when integrating it with our firewall. The main challenge has been email protection, especially due to compatibility issues and difficulties with log access and email relay configuration."
"The solution has not found a way to block certain kinds of phishing emails."
"Email installation could be more user-friendly so that it can be done without involving the partner"
"Sophos Email has few improvements to implement, including the handling of incoming emails in the systems. It needs to add additional feature that helps in enhancing the scanning processes of these emails. While adding these features, it should work towards improving the current features also."
"A lot of legit emails get quarantined."
"Sophos Email can improve security. We would like more security for our customers."
"The solution should be able to support the cloud environment."
 

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."
