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.
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 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."
"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."
"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 have never encountered any stability issues with Abnormal."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"I would recommend Abnormal Security."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I find the anti-phishing and anti-spam features most valuable because they reduce false positives and enhance security."
"The performance is great, function checks for reputation, vaccine, and email systems are better than what is offered by other products, and the interface is really good."
"Trend Micro Email Security [EOL] has positively impacted my organization as the digital user experience is good."
"Trend Vision One has helped to reduce my time to detect and respond to threats; it was our gateway for almost 12 years."
"The technical support is good."
"The initial setup is not overly complex."
"Based on my past experience, the accuracy and reliability of Trend Micro Email Security [EOL]'s output demonstrate very minimal false positive detections, with many detections being very accurate and the AI and machine learning working perfectly, complemented by traditional signature behaviors, leading to a high detection rate and accuracy when compared to other competitor products."
"Since implementing it, we've seen a significant improvement in security. We no longer receive spam emails, and we're protected from various cyberattacks, including ransomware and social engineering."
 

Cons

"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"The pricing for academic institutions and student mailboxes is challenging."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"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."
"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."
"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."
"Trend Micro Email Security can improve on scam detection. It could use AI in this area."
"While Trend Micro Email Security [EOL] is generally effective, there are occasional delays in adapting to very new or highly targeted phishing campaigns."
"I have considered how Trend Micro Email Security [EOL] can be improved. The integration within Trend Micro environment is great, but if I want to integrate Trend Micro Email Security [EOL] with a third-party endpoint security solution, it is more challenging; if I am using Trend Micro production endpoint protection along with other Trend Micro-related solutions such as Trend Micro XDR, it works much better, but integrating with a third-party endpoint protection tool such as Microsoft Defender is different."
"Trend Micro Email Security [EOL] can be improved, especially with the API, as more security enhancements and features such as a dashboard are needed to keep up with today's market of cloud-based solutions."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"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."
"It is a bit expensive than the market price."
 

Pricing and Cost Advice

"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."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"Trend Micro Email Security's pricing is reasonable."
"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 is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"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 tool must improve its pricing."
"It's a VPN solution. Trend Micro is reasonably priced."
"The cost is about $6,000 for 300 users for one year."
