Simplify's Take

What believers are saying

  • March 2025 Azure specialization expands migration demand across existing Microsoft accounts.
  • Illumio named Sentinel 2025 MSP of the Year, signaling stronger security-sales momentum.
  • HPT expands geographic reach and technical depth without exposing undisclosed purchase price.

What critics are saying

  • Acquiring HPT in 2025 stretches integration while customers expect seamless delivery.
  • Microsoft, Zscaler, and Illumio own the stack; Sentinel risks becoming a margin-thin integrator.
  • Private ownership and limited disclosures hide churn, pricing pressure, and contract losses.

What makes Sentinel Technologies unique

  • Sentinel has kept the same leadership since 1982, strengthening client trust and execution.
  • Fortis and CloudSelect bundle managed security, cloud, and lifecycle services under one provider.
  • March 2025 Azure specialization and Illumio MSP award validate its technical credibility.
