Network Architect at IP Dimension

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.

Cybersecurity Engineer Lead at Johnson & Johnson

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

"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."

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"I'm very satisfied with the environment and the dashboard."

"Cloudflare Access is part of the Zero Trust philosophy."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"It is a stable solution."

"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."

More Cloudflare One pros

"The most valuable feature is the straightforward setup."

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."

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

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

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

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

"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."

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"The product helps reduce the number of malicious emails reaching the user's inbox."

"The product protects my email."

"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."

"Trellix Collaboration Security is valued for being a stable and comprehensive solution that fulfills customer needs."

"We can control this solution from the cloud and are able to access it from wherever we are."

"Trellix Collaboration Security has positively impacted my organization by improving security, making teamwork more effective, and ensuring collaboration has become smoother."

"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."

"I rely on Trellix Collaboration Security because the sensors are highly reliable and high-performance sensors that can handle traffic efficiently."

Cons

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

"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."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"Cloudflare DDoS has poor technical support."

"They don't have a person to provide support for customers using the solution under their free plan."

"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."

"The response time for support must be reduced."

"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."

More Cloudflare One cons

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

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

"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."

"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."

"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."

"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 needs better support."

"The reporting aspect of the solution needs improvement."

"I would like to see this solution become more flexible."

"Sometimes especially zero-day spam emails can be passed to the user's inbox."

"The custom tailoring is limited."

"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."

"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."

More Trellix Collaboration Security cons

Pricing and Cost Advice

"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 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."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The prices are slightly expensive."

"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 solution is not that 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 solution is not expensive."

"The cost is very high."

"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."

"The licensing is on a yearly basis."

"The solution requires a license to be purchased for every user."

Email is the number one vector used by cybercriminals to penetrate and attack enterprise IT systems.

Trellix Collaboration Security is a comprehensive solution designed to protect sensitive data and ensure secure collaboration within organizations. With the increasing reliance on digital platforms for communication and collaboration, it is crucial to have robust security measures in place. Trellix Collaboration Security offers a range of features to safeguard data and prevent unauthorized access.

One of the key features of Trellix Collaboration Security is its advanced encryption capabilities. All data transmitted and stored within the platform is encrypted using industry-standard encryption algorithms, ensuring that it remains secure and protected from potential threats. This encryption extends to all communication channels, including emails, file transfers, and instant messaging, providing end-to-end security.

To further enhance security, Trellix Collaboration Security incorporates multi-factor authentication. This means that users are required to provide multiple forms of identification, such as passwords, biometrics, or security tokens, to access the platform. This significantly reduces the risk of unauthorized access, as even if one factor is compromised, the others provide an additional layer of protection.

In addition to encryption and multi-factor authentication, Trellix Collaboration Security offers robust access controls. Administrators can define and enforce granular access permissions, ensuring that only authorized individuals can view, edit, or share specific documents or folders. This helps prevent data leakage and ensures that sensitive information is only accessible to those who need it.

Trellix Collaboration Security also includes comprehensive auditing and monitoring capabilities. Administrators can track user activities, monitor file transfers, and generate detailed reports to identify any suspicious or unauthorized behavior. This proactive approach allows organizations to quickly detect and respond to potential security breaches, minimizing the impact on data integrity and confidentiality.
