CriticalSolutions, LLC Tech Stack

Cyber defense and threat intelligence for federal agencies

IT Services and IT Consulting Pasadena, MD 11–50 employees Founded 2011 Self-Owned

CriticalSolutions is a 11–50 person federal cybersecurity firm built around hands-on defense work: vulnerability assessments, penetration testing, threat intelligence, and incident response across Cisco, Juniper, and Brocade infrastructure. The hiring mix (4 security roles, 1 engineering) and active projects (malware analysis, compliance monitoring, multivendor routing) signal a team scaling detection and response capabilities rather than platform development. A stated need for senior engineering talent suggests they're hitting a bottleneck in operationalizing their security stack.
