NancyHartman - PeerSpot reviewer
Business Process Manager/ Educational Technologist at a educational organization with 1,001-5,000 employees
Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.
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.
