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 robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

Quotes from Members

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

Pros

"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare Access is a stable solution."
"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."
"It is a stable solution."
"The blocking feature is very good."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."
"Secure Email Threat Defense's scalability is good."
"This solution is easy to use."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"It's very easy to deploy and configure."
"Cisco's technical support is very good."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"I like the Antigena feature in Darktrace, as it offers immediate response and is helpful."
"t was pretty as far as the granularity of what you were getting out of it."
"Darktrace has improved our knowledge of abnormal phenomenen which could have potentially be hazardous for the organization."
"Darktrace provides better visibility into network risks, allowing you to take preemptive action against risky user behavior."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"It is very easy to work with Darktrace once you know how it works and the type of permissions that you need to get related to the security over a network. The interface is awesome. I'm sure that you have seen Ironman, and you know Jarvis, the computer of Tony Stark. The interface of Darktrace is very similar, and you can see in 3D, like a hologram, the whole network, traffic, and all the traces inside the network. The interface is awesome, and it provides a lot of information. At least for us, it is very easy to handle this interface, get the reports, and do the interpretation of those reports. Darktrace also provides mobile monitoring. With an app on your mobile phone, you can view the information live, which is very useful for area directors and field engineers. Darktrace can be also correlated with any type of big data solution, such as Splunk."
"The solution is outstanding from a monitoring perspective."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
 

Cons

"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."
"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."
"Cloudflare DDoS has poor technical support."
"Operating and tuning the product is difficult."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Our subscription plan for the solution has a limitation of bot signatures."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
"The pricing could always be better."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The physical appliance has been discontinued, although the platform still exists."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The product is considered expensive compared to others."
"We want to continue using Darktrace but it's very expensive."
"The solution could be easier to use."
"Although we haven't detected any network threats since implementing Darktrace, we are unsure of its efficacy. It would be beneficial if the solution could offer additional details to the user regarding any potential or prevented threats. Additionally, there could be better search tools and integration."
"The product doesn't have an endpoint agent that can react to triggers set on the device,"
"Darktrace does not have any capabilities to configure. So I would like to see supervised machines and capabilities in the next version."
"I believe their network monitoring device licensing module could use some improvement."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 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 solution’s pricing is manageable."
"It is expensive compared to other vendors."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The feedback from vendors and customer is that it is expensive."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"The pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."
"The pricing is quite high, estimated at around $350,000 per year."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"The solution is about $6,000 per quarter."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"It is a very expensive product."
