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.

AI has helped classify threat types more accurately but product ownership can improve
Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support
We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. 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. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

Quotes from Members

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

Pros

"Enables me to work from two locations."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"The solution has different options that can be used to differentiate DDoS attacks."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"It will take the blow rather than our applications should an attack occur."
"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 protects us from being business email compromised, which is invaluable for maintaining our security."
"Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"I would recommend Abnormal Security."
"I have never encountered any stability issues with Abnormal."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"I highly recommend it as one of the best choices."
"It has an efficient email filtering feature."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"Secure Email Threat Defense's scalability is good."
"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."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"I would like to have the ability to customize the auto-remediation feature."
"One feature I'd love to see is outbound scanning."
"For Abnormal Security as a product, I would say probably somewhere around a seven, as there are some other areas where they can improve to achieve a higher rating."
"The biggest pain point for us is the lack of support for on-premise email systems."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"The solution is a bit expensive. It could be cheaper."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"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."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
"This solution could be improved by integration with Sandbox."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"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 solution's pricing lacks transparency."
"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."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The license is based on the user count, so the number of users that have an email address in the organization."
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The feedback from vendors and customer is that it is expensive."
"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 solution’s pricing is manageable."
