ISI serves 900+ defense contractors with CMMC and NIST compliance, facility clearances, and managed IT/security services. The hiring mix—security roles dominating, support expanding, and a new HR director on board—reflects operational pressure: pain-point data shows renewal management, high-volume caseloads, and support surge as active friction points, suggesting the company is scaling service delivery faster than its internal processes can handle.
