CHANDLER, Ariz., August 20, 2026 — PrismHR, a Vensure Employer Solutions company and the leading HR technology software innovator for service providers across the U.S., today announced the appointment of Michael Lockhart as Chief Information Security Officer (CISO), overseeing the strategy and operations designed to protect the technology, infrastructure, and data that power PrismHR’s platform.
In his role, Lockhart will focus on a security operating model built around four key pillars: minimum viable security, security maturity, cyber-risk management, and external governance, helping ensure PrismHR’s security strategy evolves with changing threats, technologies and regulatory requirements.
“The trust our clients place in PrismHR is one of our most important responsibilities,” said Mike DeLessio, President of PrismHR. “Michael brings a rare combination of technical expertise, strategic leadership and business perspective that will help us continue strengthening our security program while supporting innovation across our platform. His experience building security capabilities at scale will be invaluable as we continue to evolve and meet the needs of our clients.”
Lockhart brings nearly 30 years of technology and cybersecurity experience to the role. His professional journey spans DevOps, software engineering, security operations, penetration testing and at-scale architecture, giving him a unique perspective on securing complex platforms while supporting business growth and customer success. Prior to joining PrismHR, Lockhart held several leadership positions at Salesforce, including serving as Director of Governance for MuleSoft’s application programming interface (API) platform. He most recently served as Chief Information Security Officer for EagleView, the global leader in SaaS-delivered aerial imagery.
Throughout his career, he has guided organizations through mergers and acquisitions, advanced complex compliance initiatives, including SOC 2 and ISO 27001 certifications, and built enterprise security programs that enable growth, innovation and operational resilience. His broad cybersecurity experience provides valuable perspective for protecting the modern HR technology platforms that support PEOs, ASOs, payroll service providers and the businesses they serve.
“Trust matters,” said Lockhart. “Our responsibility is to help ensure customer data remains safe so our clients can focus on growth with confidence. Security is not simply about protecting systems. It’s about creating an environment where organizations can innovate, adapt, and succeed knowing the platform they rely on is secure, resilient, and continuously evolving to meet new challenges.”
