Messageware OWA Guard is an on-premises security application that enhances authentication for Microsoft Exchange Server, specifically for Outlook Web App (OWA) and ActiveSync environments. It functions as an in-application security product to protect against logon and password attacks, such as brute-force and phishing, by securing exposed Client Access Servers (CAS). The software provides authentication security features not natively available within Exchange Server.
The system tracks and records all logon activity, enabling administrators to analyze threats and implement customized security policies. Its defensive mechanisms include dynamic CAPTCHA challenges, tarpitting, and geo-location blocking. OWA Guard also provides analytical reporting, automated system alerts for suspicious behavior, and an end-user interface to view recent account activity and perform password resets.
