NinjaOne®, unifying IT to simplify work, today announced the appointment of Mitchell Plonski as Senior Vice President of Global Public Sector. Plonski joins NinjaOne’s executive leadership team and will drive the company’s public sector strategy and growth globally. In this role, Plonski will partner closely with government and public sector customers worldwide, helping them simplify IT operations so their teams can focus on additional strategic work.

Plonski brings 23 years of experience scaling public sector organisations across federal and enterprise markets. Most recently, he served as President of Halcyon, where he led all federal and international public sector go-to-market teams while accelerating commercial enterprise and strategic growth. Prior to Halcyon, he was co-founder and Chief Revenue Officer at Shift5, where he oversaw federal, commercial, and international revenue and cultivated key executive and legislative relationships to scale the company’s products across the U.S. Government and international partners.

Earlier in his career, Plonski served as a Senior Duty Officer in the White House Situation Room with the National Security Council and held operations and executive management roles at the Office of the Director of National Intelligence. He also served on the U.S. State Department’s International Special Events Group Executive Board, where he chaired the Intelligence Subcommittee responsible for coordinating the U.S. Government’s overall intelligence and security posture for international special events. He began his career in the U.S. Army as a non-commissioned officer.

“Mitchell’s deep experience serving public sector organisations makes him the ideal leader to accelerate NinjaOne’s next chapter of public sector growth,” said Sal Sferlazza, CEO and co-founder of NinjaOne. “Mitchell’s leadership, combined with our continued investment in FedRAMP Moderate and High, sends a clear signal that NinjaOne is committed to being a long-term partner for public sector organisations as they modernise and secure their IT environments.”

“I have worked alongside public sector IT teams long enough to know how hard their job is. Too many tools, not enough visibility, and no margin for downtime with high expectations and thin budgets. NinjaOne can solve each of these issues, and that’s ultimately what makes me so excited for this opportunity,” said Plonski. “More than 1,500 state, local, and education organisations trust NinjaOne to unify IT, and the NinjaOne value proposition is uniquely aligned to federal agencies’ missions and visions. I’m excited to do everything I can to help our customers succeed.”

Plonski’s appointment follows a period of significant momentum for NinjaOne’s public sector business. The company achieved FedRAMP Authorisation at the Moderate Impact Level in September 2025 and received GovRAMP Authorisation at the Moderate Impact Level in August 2025, which simplifies the procurement process for public sector organisations, making it easier for them to unify IT operations. These milestones, combined with NinjaOne securing a $12.3 billion valuation and more than $400 million in Series C extensions, underscore the company’s investment in serving government and public sector customers at scale.
