Mainframe Assessment

Assess your strategic legacy systems
Even today, mainframes remain at the core of many of the most critical infrastructures, especially in the financial and government sectors. Their exposure in private, third-party, or hybrid networks requires a detailed analysis of access controls, exposed services, and integration points with modern IT systems.

A specialized technical approach to z/OS systems

We analyze the configuration of IBM z/OS subsystems, network services, and applications (e.g., TN3270/VTAM, TSO/ISPF/SDSF, OMVS/USS, RACF, CICS, FTP, DB2, JCL, HTTP/S, etc.). The assessment highlights insecure configurations, improper dataset sharing, excessive privileges, and uncontrolled privilege escalation paths.

We address common high-risk scenarios such as:

Unauthorized access via weak credentials or insecure TN3270 sessions

Malicious job submissions exploited to escalate privileges

Shared datasets with unrestricted read/write access

Combined misconfigurations enabling stealthy lateral movement

This service is ideal for teams managing IBM mainframes and seeking compliance with current security standards (e.g., RACF hardening, NIST SP 800-53, DORA).
