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.

AI has helped classify threat types more accurately but product ownership can improve
Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

Advanced email defenses have reduced phishing incidents and improved threat visibility
Trellix Email Security detects and blocks threats effectively. The best features Trellix Email Security offers are advanced attachment sandboxing and URL reputation analysis. It helps in detecting zero-days and signature-less threats. It blocks malicious websites even after delivery. The advanced attachment sandbox and URL reputation analysis specifically helps my organization by detecting zero-day or signature-less threats. It blocks malicious URLs even after delivery. It reduces ransomware risk originating from email. This significantly lowers successful phishing attempts. The impact of Trellix Email Security includes a reduction in malicious emails reaching users, a decrease in phishing-related incidents, reduced SOC workload related to email investigation, and better visibility into targeted campaigns.

Quotes from Members

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

Pros

"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It is a stable solution."
"Enables me to work from two locations."
"Cloudflare is simple to use."
"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."
"This solution is easy to understand and easy to configure."
"Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish."
"I would recommend Abnormal Security."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"The impact of Trellix Email Security includes a reduction in malicious emails reaching users, a decrease in phishing-related incidents, reduced SOC workload related to email investigation, and better visibility into targeted campaigns."
"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."
"For email spam and malware threat prevention, Trellix Email Security just works and I really appreciate the product."
"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."
"Trellix Email Security has improved risk mitigation, increased efficiency, and reduced cost in my organization."
"Compared to other email solutions such as Cisco, price-wise, we get this solution within 50 to 60% of the average."
"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 impact of Trellix Email Security includes a reduction in malicious emails reaching users, a decrease in phishing-related incidents, reduced SOC workload related to email investigation, and better visibility into targeted campaigns."
 

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"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."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Our customers no longer use Cloudflare because its service is subpar."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cloudflare DDoS has poor technical support."
"The onboarding process can be improved a little bit."
"There could be more selectable options and more granular selections available."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"The pricing for academic institutions and student mailboxes is challenging."
"One feature I'd love to see is outbound scanning."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"I would like to have the ability to customize the auto-remediation feature."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"For potential areas of improvement, Trellix can enable proper single sign-on as opposed to a local username and password."
"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."
"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 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."
"In my opinion, Trellix Email Security could be improved by making the administrative interface more intuitive, incorporating more dynamic user-based risk scoring, and offering more customizable executive dashboards."
"In my opinion, Trellix Email Security could be improved by making the administrative interface more intuitive, incorporating more dynamic user-based risk scoring, and offering more customizable executive dashboards."
"I think Trellix Email Security can be improved by addressing some false positives."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"The prices are slightly expensive."
"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."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
