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.

Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

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

"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare, in my opinion, was easy to implement."
"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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"It blocks bulk marketing messages, graymail, spam, and provides advanced malware protection."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"The security features are valuable."
"Apart from the improvement needed to the filters, it was all good."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"The tech engineers are very knowledgeable."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"The most valuable features of Darktrace are the tracing of unusual external emails and monitoring the local network."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"I am impressed with the product's ability to give insights into network traffic."
"The most valuable feature of Darktrace is its ability to detect and counter threats before they occur."
"The solution is powerful and very useful, it has the ability to avert many attacks."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"Provides great network protection."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The initial onboarding was causing us some confusion."
"Our customers no longer use Cloudflare because its service is subpar."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"For the topic of improvement, providing some training material is one of my suggestions."
"Scalability has certain shortcomings and needs to be improved because there are service providers who provide better scalability.v"
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"We would like to see more options for the customization of content filters."
"The solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working."
"The user interface needs massive improvement. While the device works fine and it's not complicated to write policies, renaming menu items and showing policy flow in conjunction with the application could help."
"The user interface could be updated."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"Darkforce could be improved in the range of the interface; how to interact with the actions it's taking or not taking."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"It takes time to go through the interface and pick up things. If it were a more straightforward interface, then it would free up time."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"Darktrace should have more automation and integrations with other security monitoring tools."
"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
 

Pricing and Cost Advice

"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."
"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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The solution is expensive."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"It is a relatively expensive option compared to other alternatives."
"It is a reasonably priced solution."
"Cisco Secure Email is expensive, but we get what we pay for."
"The product's price falls on the higher side when compared to the other products on the market."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"It is inexpensive considering what it can do and the competition."
"The pricing is subscription-based and it is high."
