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

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

Pros

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"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."

"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, in my opinion, was easy to implement."

"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."

"This solution is easy to understand and easy to configure."

"Cloudflare is simple to use."

More Cloudflare One pros

"The integration rate is very high in Kaspersky, which is why most of our customers like it."

"The most valuable features are the anti-phishing and anti-spam capabilities."

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."

"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 most valuable feature is the straightforward setup."

"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."

"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."

"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."

"The solution's identity proxy feature is very good and reliable."

"The most significant aspect is the response filtering concerning attachments and links."

"Sophos already has Sandbox, and if any issues are identified, Sophos blocks that particular mail and site instantly, which is why customers are very happy and safe from other attacks."

"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."

"Endpoint and server protection are very effective."

"I found the user interface friendly."

"Sophos Email provides both inbound and outbound filtering."

More Sophos Email pros

Cons

"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."

"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."

"Cloudflare DDoS has poor technical support."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"Lacks a VPN feature to provide a secure connection to the data center."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"The initial onboarding was causing us some confusion."

More Cloudflare One cons

"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."

"The solution is not 100 percent stable and that can use improvement."

"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."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"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."

"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"Enhancing rule creation and customization features would provide users with greater control over their email security settings."

"The tool has some performance issues and bugs, making it an area where improvements are required."

"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."

"Lacks visibility into spam emails."

"Sophos Email could improve DLP features."

"The security of the solution could improve."

"The main drawback is regarding the technical support."

"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."
