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.

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.

Ease of deployment and cost-effectiveness boost operational efficiency
I have recommendations for increasing dashboard customization. Currently, we are using custom dashboards, but they are not effectively customizable. If they provide better customization options, it would be easier to understand everything in a single dashboard instead of navigating through dropdown menus to see reports. Additionally, log retention is currently 30 days, but some customers request to extend it to 60 days. Having 60 days of log retention would be helpful for maintaining logs.

Quotes from Members

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

Pros

"Cloudflare is simple to use."
"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Access is a stable solution."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare is simple to use."
"The blocking feature is very good."
"The tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."
"I would recommend Sophos Email to both end-users and other entities that want to protect their emails."
"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 in the cloud and integrated with its firewall."
"The anti-malware, risk scanning has been pretty spot on."
"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 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."
"The platform is scalable when installed on server-based systems."
"Trellix Email Security is one of the good parts because all our organizations are very aware of email security and they are maybe using some exchange server, which is related to that email security purpose."
"Compared to other email solutions such as Cisco, price-wise, we get this solution within 50 to 60% of the average."
"For email spam and malware threat prevention, Trellix Email Security just works and I really appreciate the product."
"Trellix Email Security has improved risk mitigation, increased efficiency, and reduced cost in my organization."
"Overall, my daily experience with Trellix Email Security shows that it is a great solution to protect against malicious or phishing emails with accuracy and ease of use."
"Trellix Email Security has positively impacted my organization as it is user-friendly and does a good job detecting malicious attachments in email, providing complete email protection against all users and working well to stop advanced threats."
 

Cons

"Cloudflare DDoS has poor technical support."
"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."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The initial onboarding was causing us some confusion."
"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."
"Feedback could be enhanced."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The solution should be able to support the cloud environment."
"Email installation could be more user-friendly so that it can be done without involving the partner"
"It was sometimes hard to find the settings in the solution's interface."
"The solution should be able to support the cloud environment."
"Sophos Email could better detect fake emails, especially when the domain names are similar. It needs to improve spotting spoofed domains, like when one letter differs in a domain name. It also needs to incorporate AI detection. Barracuda detects suspicious emails better. However, malware scanning is better in Sophos Email."
"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 installation of Sophos Email could be easier. It's a bit difficult because setting up the email virtually requires some bit of technical knowledge."
"The tool has some performance issues and bugs, making it an area where improvements are required."
"I think Trellix Email Security can be improved as the console for routing is sometimes slow and I have experienced some false positives, particularly with riskware detection, which has a lot of false positives."
"For potential areas of improvement, Trellix can enable proper single sign-on as opposed to a local username and password."
"However, it was somewhat difficult to block URL-based threats and the security settings were complex, making it difficult for us to use features beyond basic security."
"I think Trellix Email Security can be improved by addressing some false positives."
"Threat intelligence is adequate because they are using Microsoft GTI threat intelligence, but we need to increase protection against phishing and spam mails."
"I think Trellix Email Security needs to improve different sides of email security, especially the filtering process."
 

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 solution is not that expensive."

"We use exchange licenses, for which we get immediate support from Sophos."
