1. Corsica Technologies

Corsica Technologies is a leading MSP with 1,000+ customers scattered across the United States and the world at large. The company takes a “true partnership” approach to managed services, with an emphasis on alignment with customer priorities, responsiveness of the Corsica team, and an engagement model that puts customers first—including 100% predictable monthly pricing.

As a top managed service provider, Corsica Technologies wins numerous awards and publishes case studies from clients in many industries.

The company also maintains capabilities not typically found in other MSPs, such as EDI support, AI managed services, and data integration. This allows customers to work with one vendor rather than acting as a referee between multiple service providers.

Corsica Technologies regularly earns positive customer reviews on G2 and Cloudtango.

Corsica Technologies is best for:

  • Companies of any size
  • Companies that need comprehensive, bundled services
  • Companies that need predictable monthly pricing and unlimited service consumption
  • Companies that need EDI and data integration in addition to IT and cybersecurity
  • Companies that need a Cybersecurity Service Guarantee that covers the cost of incident remediation services (with limitations)

Service portfolio

Corsica Technologies covers all standard service categories in the MSP industry, such as IT support, managed network services, managed cybersecurity, managed cloud services, and more. The company also offers services that most MSPs don’t offer, such as AI managed services, data integration, and EDI support.

Here’s the high-level list of all our service categories.

  • Managed cybersecurity services
  • Managed IT services
  • Compliance services
  • AI managed services
  • Technology consulting
  • Data integration
  • EDI
  • Digital transformation

100% predictable pricing model

Most MSPs bill per user, per device, per billable hour, or some combination of the above.

This can create fluctuating costs for customers, particularly if the contract specifies many types of activities that aren’t in scope.

Corsica Technologies is different. Our team works with you to determine your needs and settle on a fixed monthly price. That price will never change over the duration of the contract—even as your service needs fluctuate from month to month. 

Our predictable billing model aligns incentives for proactive support and continuous improvement, enabling accurate budget forecasting and simplifying vendor management.

Key differentiators

Here’s what sets Corsica Technologies apart from other MSPs.

  • 100% predictable monthly pricing
  • Data integration capabilities
  • EDI support
  • Cybersecurity Service Guarantee that covers the cost of incident remediation services, with limitations
Jake Hoag - Operations manager, More Farm Stores
“What attracted me to Corsica the most was the predictable billing. Whether it was break/fix issues or projects, I knew we wouldn’t have capital expenditures. We could actually get things done that we had band-aided.”

—Jake Hoag, Operations Manager
