Who is Sun Management?
Sun Management is a leading security solutions provider in the Mid-Atlantic supporting Enterprise, Commercial, SLED, and Federal Customers. The Principals, Jim and John Vanderzon, brothers, are both ex-engineers who enjoy the challenge of solving the most complex IT business initiatives. With ever-evolving technology trends, Sun Management helps Customers accelerate adoption of these trends through engineering, training, and education with strategic Partners and solutions. Leading edge technology and solutions require in-depth engineering support to be successful.
Sun Management recognizes the rapid evolution of internet security and the necessity of ongoing training as part of successful projects. Sun Management invests in its engineering expertise, having a minimum of two engineers certified to support each strategic Partner in our product portfolio. Sun Management offers a comprehensive IT roadmap to our customers differentiating them from their Peers, fulfilling IT business objectives, and elevated business outcomes.

Palo Alto Networks

This same commitment to focus and excellence is reflected in Sun’s MSSP offering. While many MSSPs attempt to support a broad range of security platforms, Sun takes a different approach. Our MSSP practice is built around a select set of industry-leading SIEM, SOAR, and firewall technologies, allowing our team to develop deep expertise and deliver consistently high-quality outcomes. Rather than trying to be everything to everyone, we focus on being exceptional in the areas where we provide the greatest value.
