Job description

Cimcor is an industry leader in developing innovative security, integrity and compliance software solutions. The firm is on the front lines of global corporate, government and military initiatives to protect critical IT infrastructure and has consistently brought IT integrity innovations to market. Cimcor's flagship software product, CimTrak, helps organizations monitor and protect a wide range of physical, network and virtual IT assets in real-time. The CimTrak Integrity Suite protects your critical files, registry, configuration settings, users, policies, network devices and more from changes, whether malicious or accidental, that can take down your IT infrastructure, threaten critical/sensitive data, or cause non-compliance with regulations such as PCI, HIPAA, CMMC and many more. CimTrak eliminates the overwhelming change noise to pinpoint unwanted, unauthorized and unexpected activity in real-time to create and establish a trusted and resilient infrastructure. CimTrak enables change reconciliation by providing a side-by-side comparison highlighting real-time changes or change over time.

Furthermore, CimTrak has the functionality that can prevent changes entirely for those files and directories that should never change.
