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

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, in my opinion, was easy to implement."
"Cloudflare DDoS mitigates DDoS attacks."
"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 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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"I'm very satisfied with the environment and the dashboard."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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 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."
"We have seen a return on investment because if we would have received a phishing email, Microsoft Defender for Office 365 would help out to detect the threat instead of crashing down the whole company."
"Scalability-wise, I do not think there are any issues so far."
"Microsoft Defender for Office 365 is a cloud-based email filtering service that helps protect our organization against unknown malware and viruses by providing robust zero-day protection and includes features to safeguard our organization from harmful links in real-time."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"The basic features are okay and I'm satisfied with the Defender."
"It has significantly decreased my time to detection and response."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"It is one of the greatest solutions to have or to complement any other security solution such as Proofpoint or IronPort."
"I like FireEye's filtering, spam digests, and its advanced threat review of email flow. It also has a broad range of riskware rules you can deploy."
"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."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"The solution's most valuable feature is its simplicity. It's very user-friendly."
"After implementing Trellix Collaboration Security, we have not encountered any incidents related to ransomware."
"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 Email Security is easy to use."
 

Cons

"The response time for support must be reduced."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Operating and tuning the product is difficult."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that?"
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The custom alerts have to improve a lot."
"Microsoft Defender for Office 365 should be more proactive."
"I assess the stability and reliability of the solution as seven out of ten."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"I deduct two points because while we are using it for insiders, we still rely on another solution for gateway level security, which makes us use two different solutions for the same purpose."
"We're not really that satisfied with technical support. They are too slow to respond."
"Trellix Collaboration Security can be improved by making the reporting and analysis tools more detailed."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"The solution must provide features to scan QR codes for threats."
"The cloud product is not open to the customers. If the system itself could be more open to the customer, I'd be able to configure it more specifically."
"I chose a nine out of ten because some improvements are required, especially concerning East-West traffic or zero-day vulnerabilities."
"I would rate them as a 1.5. The new hub created in India is not good."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 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."
"The solution's pricing lacks transparency."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is very expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It's a user-base subscription."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The licensing is on a yearly basis."
"The solution requires a license to be purchased for every user."
"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."
