Best Managed Security Services Providers (MSSPs)

Researched and written by Lauren Worth

Managed security service providers (MSSPs) make up a branch of IT outsourcing that performs a variety of IT security-related tasks and reduces internal staffing needs within client organizations. Managed security services (MSSs) can include any number of cybersecurity services, based on an individual provider’s capabilities and the specific requests of each client. MSSPs often help monitor IT compliance and general network security around the clock, deploying necessary updates and responding to incidents when necessary. Businesses can alleviate the pressure placed on in-house IT departments with partial or comprehensive MSS from a qualified provider.

Businesses can work with cybersecurity consultants to determine the extent of security needs and whether key functions would benefit from an MSSP. Businesses should deploy some amount of IT security software internally to supplement any managed services in order to maximize protection across all company data and devices.
