What does a managed security service provider in Chicago do?
A managed security service provider in Chicago monitors, manages and responds to cybersecurity threats on behalf of client organizations under an ongoing contract. Chicago has a strong concentration of MSSPs delivering SOC-as-a-service, EDR/XDR, SIEM management, penetration testing and compliance support, driven by the city’s dense finance, healthcare and legal sectors with strict regulatory needs.
