  • Business Objective

    In a complex world and faced with an ever-changing threat landscape, organisations everywhere are looking to improve security management on the mainframe. Organisations worldwide want to better understand mainframe threats and vulnerabilities to:

    • Protect the organisation, systems and confidential data more effectively
    • Identify security threats as soon as they occur
    • Reduce the risk of security breaches occurring in the first place

    However, most mainframe security monitors simply collect security data and send it to a SIEM. Collecting data is the easy part: the real value lies in transforming that data into useable insight.

    In response, RSM Partners’ security consultants have developed zDetect software using knowledge and experience gained working for leading organisations on mainframe security management.

    RSM Solution

    zDetect is a powerful z/OS mainframe security monitoring tool that detects actual and potential security issues in real time. Unlike other security monitors, it doesn’t just collect security related information to send to an SIEM: zDetect monitors, records and uses sophisticated internal security algorithms to apply intelligent analysis to detect suspicious events.

    Events captured by zDetect can be sent to a SIEM or visualised through its easy to use yet comprehensive dashboard interface, running on a standard web browser.
