    Open-Xchange releases OX Abuse Shield v2.0

    Open-Xchange is pleased to announce the release of the new major version of OX Abuse Shield v2.0.

    Open-Xchange decided to re-name the product from Dovecot Anti-Abuse Shield to OX Abuse Shield. This name change corresponds to the ability to use OX Abuse Shield in different environments.

    OX Abuse Shield provides abuse-prevention for Web Applications (including Webmail), POP, and IMAP. It is integrated with both OX App Suite and Dovecot Pro to prevent login and authentication abuse as well as protecting against brute-force attacks.

    The goal of OX Abuse Shield is to detect brute forcing of passwords across many servers, services and instances, as well as enforce policy for authentication and authorization. In order to support the real world, brute force detection policy can be tailored to deal with "bulk, but legitimate" users of your service, as well as botnet-wide slow-scans of passwords.

    The new OX Abuse Shield v2.0 provides the following main improvements and new features:
    • Long-Term Storage of Login Data in Elasticsearch
      Storing all login reports in Elasticsearch; this new functionality is used for sophisticated anomaly detection features such as detecting suspicious logins.
    • Suspicious Login Detection
      Sending email alerts to end-users or webhooks to abuse and operations teams when logins are detected as suspicious due to anomalies from previous logins.
    • - Compromised Account Reports
      Periodic reports, based on long-term data stored in Elasticsearch, sent via webhooks to abuse and operations teams about potentially compromised users and IP addresses abusing the system.
