CV
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.

Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.
Felipe Antoniazzi - PeerSpot reviewer
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

"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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"It is a stable solution."
"Clover is the best product globally."
"Cloudflare is simple to use."
"Cloudflare is by far the most effective solution that I have come across."
"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The product protects my email."
"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."
"The initial setup is simple."
"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft, and the solution is easy to use."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"FireEye Email Security is easy to use."
"Before installing, consider potential challenges with system performance, especially when integrating multiple tools, which could slow down performance."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"Operating and tuning the product is difficult."
"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"Feedback could be enhanced."
"They don't have a person to provide support for customers using the solution under their free plan."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"It is not up to the mark in comparison with Wiz or Palo Alto."
"There is a different console for different things; I just want one consolidated console."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"Its price should be improved. Its cost is a major concern for us."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Trellix Collaboration Security can be improved by making the reporting and analysis tools more detailed."
"The reporting aspect of the solution needs improvement."
"If they want to be the primary or best solution, they need to have better email management features."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"We're not really that satisfied with technical support. They are too slow to respond."
"There is a need for improved integration with totally different products, such as a rapid server."
"In general, our company should make the tool more robust to protect our systems."
"I would like to see this solution become more flexible."
