Fortinet's momentum in the cybersecurity market involves strong, growing relationships with managed security services providers (MSSPs), according to CEO Ken Xie and CFO Keith Jensen.Among the proof points: Service providers and MSSPs remained one of Fortinet's top customer segments during Q1 of 2019, accounting for 10 of Fortinet's top 25 deals in the quarter, Jensen revealed during the cybersecurity company's May 2019 earnings call.Although cybersecurity technology remains extremely important, customers are also seeking a strong service component -- and a lot of that service component flows through Fortinet's partners, Xie added.The company is also seeking to work with "VARs that are looking to provide MSSP-type services," Jenson added. "We're investing I think successfully in our channel and MSSP relationships." The growth is helping to fund additional growth in the enterprise segment, he indicated at that time.
