Common complaints - recurring incumbent review gaps = the wedge to build
Requires significant time, professional guidance, and handholding to set up and configure properly; non-intuitive concepts.
Overwhelming interface; scattered user management across multiple menus; needs graphical inputs for admin usability.
Block categories combined rather than individual; limited email text customization; inflexible outgoing queue management.
Frequent false positives for phishing detection and listserv emails; overly aggressive blocking of legitimate encrypted attachments.
Limited Office 365 integration; lacks API-based integration; LDAP interface for on-prem systems needs improvement.
High cost relative to competitors; essential features like health checks treated as costly add-ons.
Outdated or missing online documentation; inconsistent phishing detection allowing clearly malicious emails through.
