    FireMon delivers Network Security Policy Control for the Modern Enterprise.

    Most enterprises run firewalls from multiple vendors alongside cloud security groups and microsegmentation platforms, and no single console can say whether it all works together. We believe policy is the control plane for network security: it defines what the environment should do, and the infrastructure carries it out. FireMon gives security teams one place to see, govern, and prove that their policy is doing what they intend, across on-prem, cloud, and hybrid environments.

    The Network Security Engineer is responsible for Network Security software development, including collaborating on developing requirements, writing technical specifications, designing, coding, and working with a team on testing and deployment. This is a key, hands-on software development position that will work closely with other team members to develop new features and functions.
