Problem Statement

Enterprises today operate in an era of constant connectivity and evolving cyber threats. Hybrid working, cloud adoption, and VoIP have extended the network perimeter, creating new vulnerabilities across WAN, LAN, and unified communications environments. Attackers now exploit encrypted traffic, misconfigured access controls, and legacy systems to gain unauthorised access.

Many organisations still rely on outdated firewalls and fragmented tools that lack the speed and automation to counter modern threats. To remain secure, businesses need a unified, intelligent, and adaptive security architecture that protects every connection without compromising performance or compliance.

Next-Generation Firewall and Unified Threat Management

NetworkX Technologies delivers integrated, multi-layered protection through the deployment of next-generation firewalls and unified threat management platforms from leading vendors including Fortinet, Cisco, Palo Alto Networks, and Check Point. These advanced systems combine deep packet inspection with intrusion prevention, application control, and SSL/TLS decryption to defend against both known and emerging threats.

Our architectures are built around intelligent traffic analysis, identity-based policy enforcement, and real-time threat prevention, ensuring that both perimeter and internal communications remain secure. By integrating these technologies within a unified management framework such as FortiManager, Panorama, or Cisco SecureX, organisations gain complete visibility and consistent policy control across WAN, LAN, and cloud environments.

Encryption and Secure Communications

Data confidentiality and integrity remain fundamental to any modern security strategy. NetworkX Technologies implements enterprise-grade encryption frameworks designed to secure traffic in motion and maintain privacy across all forms of communication. Using protocols such as IPsec, TLS 1.3, and MACsec, we ensure data exchanged between users, sites, and cloud platforms is fully protected.

Our solutions also extend to secure voice and collaboration environments. By applying Secure Real-Time Transport Protocol (SRTP) and ZRTP standards, alongside SIP-aware firewalls and secure session border controllers, we protect unified communications and voice-over-IP from interception, spoofing, and denial-of-service attacks. These capabilities maintain the integrity of conversations, conferencing systems, and call management platforms across global networks.

WAN, LAN, and Voice Network Security

NetworkX Technologies designs its security frameworks around the principle of continuous verification and context-aware protection. On the wide area network, we implement secure SD-WAN technologies such as Fortinet Secure SD-WAN, Cisco Catalyst SD-WAN, and Versa Titan to provide encrypted, policy-driven connectivity between branches, data centres, and cloud workloads.

Within local area networks, we enforce strict access control using Cisco Identity Services Engine and FortiNAC to ensure that only authorised users and compliant devices can connect. Through network segmentation using Illumio or VMware NSX, we contain potential threats and prevent lateral movement across internal environments. For voice and unified communications, we incorporate secure SBC solutions from Ribbon, AudioCodes, and Cisco CUBE to defend against toll fraud, session hijacking, and call manipulation, ensuring confidentiality and availability of all communication channels.

Firewall Modernisation and Network Segmentation

Legacy firewalls, designed for static perimeter networks, struggle to support the agility and scalability demanded by today’s hybrid environments. NetworkX Technologies modernises firewall infrastructures by deploying clustered, high-availability next-generation firewalls with advanced routing and centralised policy management. We introduce dynamic segmentation and encrypted inter-zone communication that maintain security boundaries without limiting performance.

Our transformation programmes include full lifecycle assessments, rule-set optimisation, and policy rationalisation, followed by seamless migration to modern platforms such as Check Point Maestro, Fortinet FortiGate, or Palo Alto Prisma Access. This structured approach delivers resilient, compliant, and easily managed security architectures aligned with enterprise growth.

Threat Detection and Automated Response

Modern network attacks evolve in milliseconds, demanding a defence system that reacts just as quickly. Our threat intelligence ecosystem integrates Fortinet Security Fabric, Microsoft Defender for Network, and Rapid7 InsightIDR to deliver real-time analytics and automated containment. Using artificial intelligence and machine learning, we continuously analyse encrypted traffic patterns and user behaviour to identify anomalies before they escalate into incidents.

Through our Security Operations Centre, we orchestrate automated responses that can isolate compromised devices, block malicious sessions, and remediate vulnerabilities without human delay. This proactive, intelligence-led approach ensures faster recovery, reduced risk exposure, and consistent protection across WAN, LAN, and voice infrastructures.
