As business-critical applications are a mix of cloud and on-premises resources, and users need secure access to resources from anywhere, the traditional firewall approach is no longer effective. From a single network perimeter, multiple micro-perimeters have emerged. For many companies, the application of the perimeter and traditional firewall implementations has evolved into a mix of physical, virtual, and cloud-native appliances. As a result, companies struggle to operationalize support for modern application environments. The challenges lie in ensuring consistent transparency, policy enforcement, and unified visibility of threats without opening vulnerabilities that expose the business to risks. Cisco has developed a vision for network security with NetWORK that enables a more agile, automated, and integrated approach to harmonizing policies and their enforcement in modern dynamic applications and increasingly heterogeneous networks. Secure Firewall provides the most comprehensive integrations between core network functions and network security, resulting in the safest architecture ever. The outcome is a complete security portfolio that protects your applications and users everywhere. Real-time, unified workload, and network security for integrated control in dynamic application environments. A platform approach to network security that leverages and shares information from key sources to enable faster detection, response, and remediation. SecureX permissions are included in every Cisco Secure Firewall, enabling a tightly integrated security approach that allows for threat correlation across the entire Cisco Secure portfolio and accelerates incident response.
