Network Defence
Networks, Defended.
Threats, Blocked.
Network security requires comprehensive defence-in-depth strategies that protect against advanced threats whilst maintaining network performance and operational efficiency through systematic firewall deployment, network segmentation, and intrusion detection across complex network infrastructures.
At Cordant, we implement systematic network defence through next-generation firewall deployment, intelligent network segmentation, and comprehensive intrusion detection that transforms network infrastructure into secure, monitored, and strategically protected business foundations.
We eliminate network security gaps whilst implementing layered defence strategies that prevent unauthorised access, detect malicious activity, and maintain network availability through proven network security methodologies.
Our network defence services encompass next-generation firewall deployment and architecture design, network segmentation and micro-segmentation for granular access control, and intrusion detection and prevention systems with comprehensive threat monitoring.
Next-Generation Firewall Deployment & Architecture
Implement comprehensive next-generation firewall infrastructure that provides advanced threat protection whilst enabling application visibility, user identification, and content inspection across network perimeters and internal segments.
Our NGFW deployment includes:
- Palo Alto Networks firewall deployment with threat prevention, URL filtering, and application control capabilities
- Cisco Firepower deployment with advanced malware protection and network analytics for threat intelligence
- High-availability configuration with active-passive and active-active clustering for business continuity
- Policy design and rule optimisation with application-based policies and security zone implementation
- Centralised management and reporting with panorama integration and comprehensive security analytics
Network Segmentation & Micro-Segmentation
Establish comprehensive network segmentation that isolates critical assets whilst implementing zero-trust network architectures and granular access controls for enhanced security and compliance across enterprise networks.
Our segmentation services cover:
- Network architecture design with VLAN segmentation and security zone implementation for traffic isolation
- Micro-segmentation deployment with software-defined perimeters and application-level access controls
- East-west traffic inspection with internal firewall deployment and lateral movement prevention capabilities
- Zero-trust network architecture implementation with identity-based access controls and continuous verification
- Network access control (NAC) deployment with device authentication and policy enforcement automation
- Segmentation monitoring and analytics with traffic flow analysis and security policy effectiveness measurement
- Micro-segmentation using Cisco ACI, VMware NSX, and Illumio platform deployment
- OT/IT network isolation and secure communication bridge design for critical infrastructure
Intrusion Detection & Prevention Systems
Deploy comprehensive intrusion detection and prevention systems that monitor network traffic whilst identifying threats, preventing attacks, and providing forensic capabilities for incident investigation and response.
Our IDS/IPS implementation includes:
- Network-based IDS/IPS deployment with signature-based and behavioural analysis for comprehensive threat detection
- Host-based intrusion detection with endpoint monitoring and system integrity validation capabilities
- Threat signature management with automated updates and custom rule development for environment-specific threats
- Network traffic analysis with deep packet inspection and protocol anomaly detection capabilities
- Security incident correlation with SIEM integration and automated alert management for rapid response
- Forensic analysis capabilities with packet capture and network traffic reconstruction for incident investigation
