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.

Real-time threat response has boosted detection accuracy and reduces manual investigation work
I have had challenges in the past with Trellix Collaboration Security for implementation because of issues related to compatibility. Since we worked in a global company with different operating systems, it was necessary to create different plans and different actions to implement the product.One thing I really do not prefer in Trellix Collaboration Security is not related to the console. I am a McAfee fan since the McAfee tool, and I find the console of Trellix Collaboration Security to be very user-friendly and easy to use. However, I do not know if it is related to the architecture of the product. Of course, we have modern threats based on behaviors and zero days. We have today CrowdStrike and SentinelOne, where we have better results based on threats and behavior, where it is possible to create a simulation environment based on the file detected and based on it, confirm if it really is malicious or not. In general, I believe Trellix Collaboration Security improved the console based on the last console of McAfee, but I think it is possible to improve more. It really is a good product, but in my view, it needs to improve detection based on behaviors. Regarding automations, I have implemented Trellix Collaboration Security here at Johnson & Johnson, and I implemented it in the same situation at Santander Bank and BNP Paribas Bank, where I created automations to export data for different metrics, including malicious detections, compliance, baselines, scans, last scans based on the seven days, and checking of patterns. I export everything to CSV files. Based on that, I create Power BI dashboards, and in these Power BI dashboards, I have a more executive view for different metrics to provide to myself, my manager, or director to create an executive view based on it. Another important point we use here at Johnson & Johnson and other companies is a data hub or a SIEM solution, such as Elastic or ArcSight, where we select some logs to be sent and use it to build reports and metrics.

Quotes from Members

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

Pros

"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 Access is part of the Zero Trust philosophy."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare is by far the most effective solution that I have come across."
"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."
"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."
"The solution has different options that can be used to differentiate DDoS attacks."
"Clover is the best product globally."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"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."
"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."
"The most valuable feature is the straightforward setup."
"Trellix Collaboration Security is valued for being a stable and comprehensive solution that fulfills customer needs."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"Trellix Collaboration Security has positively impacted our organization by making our collaboration environment very safe, allowing our team to share files and links without worrying about threats."
"FireEye ETP has blocked several campaigns that lead to the post compromise deployment of ransomware, Obfuscated Outlook Phishing impersonation, Attachment based Phishing."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"The accessibility is one of the features that I love; we can control it from the cloud and we can access it from anywhere."
"I'd recommend the product due to the fact that it can stop most of the phishing and malicious items from getting through our email."
"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft. Additionally, the solution is easy to use."
 

Cons

"Operating and tuning the product is difficult."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The initial onboarding was causing us some confusion."
"Feedback could be enhanced."
"The onboarding process can be improved a little bit."
"They don't have a person to provide support for customers using the solution under their free plan."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"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, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"If they want to be the primary or best solution, they need to have better email management features."
"The spam detection feature could be better."
"It really is a good product, but in my view, it needs to improve detection based on behaviors."
"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."
"I would rate them as a 1.5. The new hub created in India is not good."
"The solution must provide features to scan QR codes for threats."
"In general, our company should make the tool more robust to protect our systems."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"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."
"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 is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."

"The solution is not that expensive."
"The solution is not expensive."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"The licensing is on a yearly basis."
"The solution requires a license to be purchased for every user."
"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
