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.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

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.

Quotes from Members

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

Pros

"It is a stable solution."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Enables me to work from two locations."
"Clover is the best product globally."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare Access is part of the Zero Trust philosophy."
"Darktrace provides better visibility into network risks, allowing you to take preemptive action against risky user behavior."
"One thing I appreciate is Antigena Email, which is for email protection."
"A simple, powerful AI solution that just does all the work for you when you turn it on."
"It provides a comprehensive, detailed view of network activity and whatever is happening inside it."
"It is very stable and easy to use."
"The technical support from Darktrace is very good, including support from their resellers."
"The AI-based pattern is the most valuable feature."
"The scalability of Darktrace is very high."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The product's scalability is good."
"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 feature is its performance."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."
 

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Operating and tuning the product is difficult."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The onboarding process can be improved a little bit."
"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Lacks a VPN feature to provide a secure connection to the data center."
"Getting logs from different sources can be a challenge."
"Its threat analyzer could be better. It should also have agents. They should improve this product by installing agents for the machine to get more visibility. Currently, they are monitoring only the network. They should also monitor the agents from inside. It should also have a better pricing plan because it is an expensive product."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"Darktrace is a closed technology, meaning we know very little about how it works, including the architecture, which is significant. As a result, when we implement the system and find we're getting many false positives, we have minimal insight into why it's happening and what we can do to fix it. We don't know how the solution is configured, the criteria for threats to be determined, or the product's inner workings. We understand that they have to ensure privacy and their copyright, but we want to see some documentation or public research into the security Darktrace provides."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"The pricing needs improvement."
"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."
"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."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."
"The phishing and spam filters could use some improvement."
 

Pricing and Cost Advice

"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 solution is not that expensive."
"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."

"The pricing is normal. Considering its popularity, it's not overpriced."
"The license is expensive because the cost is based on the number of users."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The pricing has become expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
