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.

Enginner at Millennium Information Technologies
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

"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."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"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."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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."
"I have never encountered any stability issues with Abnormal."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"It has an efficient email filtering feature."
"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."
"On ease of use, it rates very high."
"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."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Cisco's technical support is very good."
"The product offers protection, email security, anti-spam, and antivirus."
 

Cons

"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."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"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."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"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."
"I would like to have the ability to customize the auto-remediation feature."
"The biggest pain point for us is the lack of support for on-premise email systems."
"One feature I'd love to see is outbound scanning."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"We encounter issues while searching for missing emails."
"The search area has room for improvement."
"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."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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 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 tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
 

Pricing and Cost Advice

"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"The license is based on the user count, so the number of users that have an email address in the organization."
"The solution’s pricing is manageable."
"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."
"It is expensive compared to other vendors."
