Our client is undergoing a comprehensive infrastructure modernisation initiative to implement a cutting-edge security framework aligned with Zero Trust principles. By leveraging our expertise, the client is strategically aligning with the NIST Zero Trust maturity model, selecting top-tier products for seamless integration to fulfil the specific capability needs of each maturity model pillar. This strategic approach is poised to establish a state-of-the-art data centre and infrastructure fortified by robust zero-trust security protocols.

To address the needs of the users and device pillars, we strategically utilised key Microsoft technologies, including Microsoft Entra (Azure AD) for robust identity management and Microsoft InTune for efficient device management. Our approach also involved leveraging tools such as Gitlab, Microsoft Purview, and TrendMicro to enhance data and application management while ensuring top-notch security measures. Considering the client's substantial on-premises network infrastructure with a mix of cloud services, we integrated VMware NSX-T to implement effective east-west micro-segmentation. This decision enhances network security and optimizes overall network performance. Moreover, we meticulously configured a suite of cutting-edge tools to fulfil the Automation Orchestration pillar requirements, including Microsoft Sentinel, Ansible, Elastic, Gigamon, and Microsoft Defender. This comprehensive setup ensures seamless automation and orchestration and enhanced visibility and analytics across the network infrastructure.

Our enterprise client sought robust firewall services with remote access capabilities to secure connectivity for their geographically dispersed workforce. Challenges arose in setting up a secure gateway for northbound and southbound traffic and delivering dependable VPN endpoints for remote access.

We effectively addressed the client's needs by deploying high-availability Palo Alto appliances at their data centre. These appliances had advanced features, including Global Protect VPN, URL filtering, and threat protection capabilities. Strategically positioned, these appliances served as comprehensive VPN endpoints and secure gateways for managing incoming and outgoing traffic. This deployment significantly bolstered the client's network security, ensuring a robust and reliable infrastructure for their distributed workforce.

A prominent organisation in the water treatment industry encountered issues with its Cisco Unified Communications (UC) solution, which caters to more than 100 end users. The current IP address setup posed efficiency, scalability, and network reliability challenges, necessitating a comprehensive overhaul. The project aimed to revamp essential UC components' outdated IP address configuration while minimising operational disruptions. The intricate environment comprised a UCS server, multiple Cisco UC virtual machines, an extensive phone network, and several Cisco Voice Gateways.

The solution involved addressing the challenges with the existing UC infrastructure, including Cisco Unified Communications Manager (CUCM), Cisco Unity Connection (CUC), and Cisco Emergency Responder (CER), which utilised cumbersome static IP addresses. These static addresses posed management and update difficulties, compounded by their placement in the same subnet as the data network, heightening security vulnerabilities and reducing network availability. The project demanded meticulous planning and coordination to seamlessly execute the IP address reconfiguration without causing service interruptions or downtime for UC users and critical applications. The reconfiguration encompassed updating the IP addresses of numerous UC devices, servers, gateways, and endpoints distributed across various sites and regions, ensuring a smooth transition to a more secure and efficient network setup.
