Former Palo Alto Networks Senior Executive and KKR Advisor Joins Viakoo to Scale Go-To-Market and Enterprise Expansion in Autonomous OT/IoT Vulnerability Remediation
LAS VEGAS — Black Hat USA — August 3, 2026 — Viakoo, Inc., the leader in automated OT/IoT device cyber hygiene and vulnerability remediation, today announced cybersecurity industry veteran John Spiliotis has joined its Advisory Board. Spiliotis brings over three decades of enterprise security leadership, sales strategy, and scale-up experience to assist Viakoo in accelerating its growth across enterprise, industrial, and cyber-physical systems markets.
The announcement comes during Black Hat USA, where enterprise security teams are increasingly focused on closing the dangerous visibility and remediation gap across unmanaged, connected IP devices and operational technology.
Spiliotis has built a reputation as one of the enterprise cybersecurity sector’s foremost sales and go-to-market executives. He previously served as Senior Vice President of America’s Sales at Palo Alto Networks, where he played a pivotal role in driving global enterprise expansion and scaling revenue. Spiliotis currently serves as an operating advisor and board member across several high-growth cybersecurity companies—including ReliaQuest and NetSPI—and is Senior Sales Advisor for private equity firm KKR.
“John’s track record of scaling enterprise cybersecurity organizations and shaping global go-to-market strategies is second to none. As organizations face mounting regulatory pressures and sophisticated threats targeting connected physical infrastructure, automated remediation is no longer optional. John’s deep strategic insight and extensive network will be invaluable as we expand our market reach and deliver autonomous cyber hygiene at global scale.”
— Bud Broomhead, CEO of Viakoo
“Enterprise security teams have spent years investing heavily in IT identity and endpoint detection, but OT and IoT devices remain a massive, unpatched blind spot. Viakoo’s approach—automating firmware updates, password management, and certificate renewals across tens of thousands of devices—addresses an urgent and unsolved problem. I’m excited to join Viakoo and work closely with Bud and the leadership team to help drive the next phase of company growth.”
