Cohesive enterprise security that increases IT efficiency and reduces firewall management costs. The integration provides an abstraction of the corporate infrastructure, allowing firewall rule sets to be quickly and easily validated for compliance against customizable OOTB templates such as STIG, MITRE ATT&CK Framework, or other industry best practices. Cyber hygiene tasks such as elimination of device misconfigurations, identification of violating traffic between zones, optimization of firewall rule sets, and change management processes for rule provisioning, deprovisioning and recertification can be easily automated. Network modeling and automation connects context from the hybrid infrastructure with threat intelligence to ensure that connectivity needs are balanced against exposure risks. An innovative technique for scanless vulnerability discovery ensures that firewalls risk posture remains continuously updated between active scan events.
