Manager, Information Technology Technical Services at a wholesaler/distributor with 5,001-10,000 employees
Automated threat detection that protects against corruption with minimal intervention
Abnormal Security is valuable because it features an automated scoring tool that doesn't require much intervention from our team. It enhances threat detection capabilities by making the process automated and is easy to scale to our entire environment. Additionally, it protects us from being business email compromised, which is invaluable for maintaining our security.
AsadAli - PeerSpot reviewer
Soc Team Lead at Super Secure
Centralized protection has transformed email security and incident investigations by reducing false positives and improving behavioral threat detection
The challenges include the challenge of finalizing a product that has all the security features or capabilities that are usually required. For example, if there is an EDR platform that's just monitoring IDS signatures, it won't be as beneficial as one with behavioral monitoring and other critical aspects required according to the best practices of the industry. Additionally, if there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team. These challenges consist of managing multiple teams and products. Trend Micro Email Security comes in and solves these problems.Trend Micro Email Security is generally a bit more difficult to implement compared to the rest of the solutions such as network security modules or EDR modules, which are much easier. Trend Micro Email Security has some complexities in implementation, but there aren't any significant shortcomings that require Trend Micro to improve.

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."
"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."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"I would recommend Abnormal Security."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"It is mostly stable."
"Trend Micro Email Security’s most valuable feature is spam filtering."
"The most valuable feature of Trend Micro Email Security is effective phishing prevention."
"The technical support is good."
"Trend Micro Email Security [EOL] prevents that from happening with its advanced detection mechanisms."
"The Email Security solution from Trend Micro is quite a strong solution."
"Trend Micro Email Security is a great point and a great advantage for us."
"Trend Micro Email Security is a robust solution with quick performance. It works autonomously without the need for an administrator."
 

Cons

"I would like to have the ability to customize the auto-remediation feature."
"One feature I'd love to see is outbound scanning."
"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."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"In terms of email security, I would not rate Trend Micro as an expert solution."
"I wish Trend Micro Email Security [EOL] could improve by ensuring that if an attachment sent from an email is suspicious, it should be opened in another remote environment built by Trend Micro."
"While Trend Micro Email Security [EOL] is generally effective, there are occasional delays in adapting to very new or highly targeted phishing campaigns."
"The initial setup was straightforward. This is a virtual appliance, it takes a short time to deploy the solution. However, it is not difficult if you understand the technology. You must have good knowledge of the email security area to set up the product correctly. There are many features in this solution and a high risk of having mistakes with the configuration."
"In terms of improvement, reducing false positives would improve the system."
"It was crucial because if remediation can be done in one or two clicks, in Trend, we have to do at least eight clicks to achieve the same result."
"Trend Micro Email Security could improve by advancing its artificial intelligence in email security. There are rules that have to be configured. There should be less configuring."
"There is a lot of room for improvement towards the phishing kind of email filtering, with the different hijacking attacks, and with the kind of password attacks which these phisher attackers do."
 

Pricing and Cost Advice

"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"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 cost is about $6,000 for 300 users for one year."
"The solution is inexpensive so we recommend it to small to mid-sized businesses."
"It is expensive. The cost is per box, and it depends on how big your environment is. Prices range from 11 to 12 dollars for licenses and can fluctuate up and down, but for environments with 4,000 to 5,000 users, it can be between 6 to 8 dollars."
"The price of Trend Micro Email Security is annual. There are no additional fees."
"The tool must improve its pricing."
"Price-wise, it is a cheap solution. I rate the solution's pricing a one on a scale of one to ten, where ten is expensive. Annual payments are made for the licensing."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"The solution's pricing is very optimum, given its quality, features, and stability."
