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.

Comprehensive detection has protected email traffic and now simplifies endpoint security work
Sophos Email security is the primary product I use. It scans all your inbound and outbound email for malware. It also has a capability for looking for phishing and spear phishing content and blocking it. Email has an extended capability that includes what's called a secure web gateway. All user traffic gets managed through that, making it a combination product. The version of the product you run determines which features are available. Reporting is competent. There is scope for more improvements, which they will do as they do every year regularly. They keep updating the product. Reporting gives you the relevant details of what is happening, so it's mature on that front. The main benefit is security for your email. The beauty of the Sophos system is that the XDR functionality runs across the system. Sophos, Trend Micro, and Microsoft are the only three that have a very strong system with this concept. XDR stands for extended detection and response, and it's a technology where the system automatically exchanges security signals between the endpoint, the email, and other similar products of the same brand. If you have Sophos Endpoint and Sophos Email, you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic. You have a very rounded security aspect.

Gateway filtering has protected our organization and provides complete email threat prevention
In my opinion, the best features Trellix Email Security offers include its use for malware analysis as well as the enterprise-wide email quarantine system. My experience with the malware analysis and quarantine features is that they are easy to manage and they have been very effective because we have been able to quarantine any suspicious emails or prevent any attempt before it affects our systems. It is also very user-friendly and has a simple interface. Policies and rules are easy to create and they work with very little downtime or operational impact. Email delivery issues are easy to investigate and troubleshoot. 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. The price is relatively the same as other competitors.

Pros

"Cloudflare Access is a stable solution."

Cons

"The onboarding process can be improved a little bit."
"Operating and tuning the product is difficult."
"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."
"Our customers no longer use Cloudflare because its service is subpar."
"They don't have a person to provide support for customers using the solution under their free plan."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The response time for support must be reduced."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
"Sophos Email can improve security. We would like more security for our customers."
"Sophos Email needs to increase the number of promos."
"While Sophos Email is generally sufficient, one challenge we face is the 24-hour email storage limitation."
"The product could include all the essential features and capabilities, similar to the on-premise, server-based version."
"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."
"The tool's integration becomes an issue when the internet connection is weak."
"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."
"Regarding technical support from Trellix, I would rate it a four because there is a lot of work that has to be done in terms of the support that is provided."
"For potential areas of improvement, Trellix can enable proper single sign-on as opposed to a local username and password."
"My main problem with support is that the response time is too long, which is the major issue."
"The biggest area for improvement in Trellix Email Security is the pricing. The solution is quite expensive."
"When we talk about security, Trellix Email Security console is very complex."
"To improve Trellix Email Security, I think the dashboard details could be enhanced."
"The customer support has been inconsistent with Trellix lately because there is a whole loopback hierarchy that you have to reach the customer service first, and then the engineer will respond, and then the customer service will feed you back again."
