On August 25, Horizon3 announced the appointment of Chad Keefer as vice president of federal sales.
In this role, Keefer will lead Horizon3’s go-to-market strategy across the federal civilian, defense and intelligence community markets, building out the sales organization, processes and partner relationships needed to scale adoption of the company’s NodeZero autonomous pentesting platform across government.
A 24-year veteran of federal go-to-market leadership, Keefer joins Horizon3 after most recently serving as head of U.S. federal at Infoblox. He previously held vice president roles at Appian, leading both the company’s Federal Civilian and Enterprise Financial Markets go-to-market strategies, and spent a decade at Forescout Technologies, rising from sales director to vice president of the Federal Civilian Business Unit and ultimately leading multi-segment sales across Public Sector, Financial Services, Healthcare, Energy and Strategic Enterprise accounts. Earlier in his career, he led federal security sales teams at IBM (BigFix) and ArcSight, spanning both Department of Defense and civilian agency programs.
Over the past 15 years, Keefer has built and led federal go-to-market teams through reorganizations, technology transformations and ground-up builds. Before his technology career, Keefer served as a Platoon Leader in the United States Marine Corps, where he led small-unit teams in high-stakes environments — experience he credits with shaping his approach to discipline, mission focus and team-building.
“Chad has spent nearly a quarter century building and scaling federal go-to-market organizations, and he brings the operator’s instinct to match our technology to the government’s mission,” said Matt Hartley, chief revenue officer at Horizon3. “As agencies move to operationalize continuous monitoring and cyber readiness mandates, Chad will help us prove those investments actually hold up against a real attacker. He’s exactly the leader we need to scale Horizon3’s federal business and build the team to support it.”
“Government agencies have invested significantly in cyber readiness,” said Keefer. “Our job is to prove those investments work against a real attacker. Can they get through the controls? Can they move through the environment? Can they reach something that matters? And when we fix the problem, can we prove the attack path is actually gone? I want to establish continuous security validation as an operational standard across civilian, defense and national security environments, and make Horizon3 a trusted part of how those organizations protect their missions. Ultimately, success means changing the standard from ‘we believe our controls are working’ to ‘we can prove they’re working.’”
Keefer’s appointment builds on Horizon3’s continued momentum in the federal market, where the company counts the NSA, CISA and other federal agencies among its more than 7,000 customers worldwide.
