Centralschweizerische Kraftwerke | Utilities | 2100 | $300M | Switzerland | Cisco Systems | Cisco Adaptive Security Appliance (ASA) | Next Generation Firewall | 2018 | Netcloud Switzerland |
In 2018, Centralschweizerische Kraftwerke deployed Cisco Adaptive Security Appliance ASA as part of a Next Generation Firewall implementation to secure OT and IT convergence for a new substation and the wider grid infrastructure. The deployment combined Cisco ASA-5500-X with FirePOWER services together with Cisco Secure Firewall ISA 3000 and Secure Firewall Management Center to provide layered network defense for operational technology environments.
The implementation emphasized deep visibility and finer-grained segmentation for OT networks, leveraging FirePOWER threat inspection and intrusion prevention capabilities and centralized policy orchestration via Secure Firewall Management Center. Functional capabilities implemented included advanced threat detection, policy-based segmentation for industrial networks, and centralized containment workflows orchestrated from the management center.
Delivered with Netcloud Switzerland, the architecture covered substation network edges and extended into grid infrastructure network segments, aligning IT and OT network controls. Secure Network Analytics was introduced as part of the broader security telemetry and detection stack, with a staged rollout through 2022 to augment centralized threat detection and containment.
Operational governance concentrated on coordinated security operations between IT and OT teams, with Secure Firewall Management Center providing the single pane for rule lifecycle and incident response coordination. The project produced explicit outcomes of improved network visibility, finer-grained OT segmentation, and centralized threat detection and containment as core operational capabilities.

ExxonMobil | Oil, Gas and Chemicals | 57900 | $323.9B | United States | Cisco Systems | Cisco Adaptive Security Appliance (ASA) | Next Generation Firewall | 2020 | n/a |
In 2020, ExxonMobil deployed Cisco Adaptive Security Appliance (ASA) as a Next Generation Firewall to strengthen network security at its Spring, Texas operational site and within its central Network Security team. The Cisco Adaptive Security Appliance (ASA) implementation concentrated on core Next Generation Firewall functions, including stateful inspection, application-aware access control, VPN termination, and intrusion prevention capabilities, with policy enforcement configured for perimeter protection and internal segmentation. The Network Security Technical Lead established rule sets, led configuration reviews, provided training and development for the Network Security team, and served as an escalation point for complex Cisco ASA installations. Operational ownership rested with network security and cyber threat intelligence functions, reflecting close collaboration between security operations and network engineering. Cisco Adaptive Security Appliance (ASA) devices were implemented alongside Juniper SRX devices in mixed-network environments, requiring interoperability practices and coordinated change control. Governance emphasized documented standard operating procedures, escalation workflows, and training-driven rollout managed by the Network Security and Cyber Threat Intelligence teams, aligning the ExxonMobil Cisco Adaptive Security Appliance (ASA) Next Generation Firewall deployment with operational models for policy orchestration and monitoring.

Freddie Mac | Banking and Financial Services | 8004 | $21.2B | United States | Cisco Systems | Cisco Adaptive Security Appliance (ASA) | Next Generation Firewall | 2022 | n/a |
In 2022, Freddie Mac deployed Cisco Adaptive Security Appliance (ASA) as a Next Generation Firewall to secure hybrid cloud and core mobility network perimeters across multiple sites and zones. The implementation targeted enterprise network security controls within cloud and on premise environments, integrating the Cisco Adaptive Security Appliance (ASA) into a broader security architecture for network and cloud teams.
Configuration work centered on Cisco Adaptive Security Appliance (ASA) firewall policies, access control lists and rule analysis, with ongoing rule modification and optimization as primary operational activities. Administrators configured logging and monitoring streams on the Cisco Adaptive Security Appliance (ASA), and maintained detailed documentation, topology diagrams and inventory to support change control and auditability.
The deployment was integrated explicitly with AWS and Azure services to support hybrid connectivity and monitoring. Integrations included AWS VPCs and Azure Virtual WAN for interconnectivity, AWS Network Firewall and Azure Firewall Manager for parallel cloud native controls, Amazon CloudWatch and Azure Monitor for centralized telemetry, and AWS IAM and Azure RBAC to govern access to firewall management functions. Authentication and device access were consolidated via Cisco Identity Services Engine, with migration of Wireless and TACACS to Cisco ISE using AWS Directory Service and Azure Active Directory for identity sources.
Operational coverage spanned core ASR 9K redundant pairs and Nexus series switching fabric, with VLAN lifecycle management and routing protocols implemented on routers including OSPF, BGP, HSRP, IPv6 and bundle Ethernet where required. The Cisco Adaptive Security Appliance (ASA) was operated alongside other perimeter and inline controls including Palo Alto platforms managed through Panorama, AWS security groups and Azure network security groups, forming a multi layer network security posture across cloud and campus environments.
Governance and process changes emphasized firewall rule governance, periodic rule reviews, standardized change procedures and regular reporting to network operations and security teams. Configuration stewardship included automated monitoring feeds to CloudWatch and Azure Monitor and role based access controls aligned to AWS IAM and Azure RBAC to enforce separation of duties for firewall administration.

NHS Wales | Government | 94325 | $2.5B | United Kingdom | Cisco Systems | Cisco Adaptive Security Appliance (ASA) | Next Generation Firewall | 2019 | n/a |
In 2019, NHS Wales, via Aneurin Bevan University Health Board, implemented Cisco Adaptive Security Appliance (ASA) alongside Cisco Software-Defined Access to segment and protect hospital networks, medical devices and the health VRF across its sites in Wales. The Cisco Adaptive Security Appliance (ASA) served as the Next Generation Firewall enforcement element within the SDA architecture, providing perimeter and microsegmentation policy enforcement across VRF instances.
The implementation encompassed firewalling, access control lists, VRF isolation and automated segmentation policies orchestrated by the SD-Access control plane, with ASA delivering stateful inspection and containment capabilities typical of a Next Generation Firewall. Configuration work focused on separating clinical device traffic from general hospital networks and enforcing policy for medical device VLANs and the health VRF.
Operational scope covered multiple hospital sites in Wales and targeted hospital networks, medical device estates and the health VRF, with network operations and clinical engineering teams responsible for policy definition and change control. Rollout sequencing aligned SD-Access fabric provisioning with ASA policy deployment to enable staged segmentation and faster enforcement of isolation controls.
Cisco's published customer story, case study published 2020, reports that the SD-Access and ASA deployment improved network automation and segmentation, reduced lateral threat risk and enabled faster threat containment. The narrative emphasizes use of Cisco Systems technologies to centralize segmentation policy and accelerate containment workflows for clinical and network operations.
