Room For Improvement

reviewer2770017 - PeerSpot reviewer
Email Security Analyst at a computer software company with 51-200 employees
Has improved threat analysis by providing clear email correspondence history and reporting tools
The best features IRONSCALES offers are the investigation tabs, headers, and correspondence history, which stand out the most for me. The investigation tabs are valuable for my work because reporting goes a long way in terms of playbooks and having a full investigation. The investigation tab knows exactly how to put the information in a way that makes it very easy for reports to get done fast. Security awareness training is a big part of IRONSCALES. The platform offers a broad spectrum in terms of what campaigns can be run for security awareness for users as well as reporting back on how users interact with their mails and understanding where the vulnerabilities lie. IRONSCALES has positively impacted my organization by making email security simple in terms of controlling mails, understanding where the threats are, and protecting the organization itself.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.
