Senior Director, Information Technology at a insurance company with 51-200 employees
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

"I have never encountered any stability issues with Abnormal."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"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 like Abnormal's threat protection with auto-remediation, but I also love its abuse mailbox feature, which automatically responds to the end user. That feature has a super-valuable security component and helps improve the user experience."
"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."
"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."
"This solution is easy to use."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"Cisco's technical support is very good."
"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."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"The solution is stable."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"On ease of use, it rates very high."
 

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."
"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."
"There could be more selectable options and more granular selections available."
"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 pricing for academic institutions and student mailboxes is challenging."
"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."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"We encounter issues while searching for missing emails."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is 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."
"This solution could be improved by integration with Sandbox."
 

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."
"The license is based on the user count, so the number of users that have an email address in the organization."
"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."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"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."
