Robert Keblusek, CTO of the Downers Grove, Ill.-based solution provider Sentinel Technologies - No. 117 on CRN’s 2017 Solution Provider 500 list – a top Cisco cybersecurity partner that has seen a more than 200 percent year-over-year growth in security sales, driven by its security-as-a-service platform, SecuritySelect.

"We’ve really taken a holistic and advanced approach to how we sell security. Security isn’t a one-time purchase anymore. It’s an ongoing effort regardless of whether the customer is doing it themselves, or we’re doing it in conjunction with them, or if they want to fully hand everything to us."
