An MSSP (Managed Security Service Provider) delivers outsourced security operations — monitoring, detection, vulnerability management, or incident support — under contract.
For Hong Kong SMEs, MSSPs often hold privileged access to cloud tenants and endpoints. Buyers should require named engineer accounts, MFA, logging, and a clear incident contact — especially for ransomware readiness. An MSSP relationship does not replace HKCERT for national coordination, nor does it automatically improve a public Trust Review score without evidence.
