The Foundation of Digital Operations
Network infrastructure is the circulatory system of every organisation. When it fails, everything fails. When it is compromised, everything is exposed. Yet network security is frequently treated as an afterthought — firewall rules piled on top of legacy architectures with little strategic coherence.
Daniel Ossio designs resilient, high-performance network architectures that balance security with operational efficiency. With 25+ years spanning enterprise networking, ISP-scale infrastructure, and mission-critical environments, Daniel brings deep protocol-level expertise to every engagement.
Network Security Services
Network Architecture
Designing segmented, resilient network topologies. VLAN strategies, micro-segmentation, SD-WAN deployment, and secure inter-site connectivity for distributed organisations.
Firewall & NGFW
Next-generation firewall deployment and policy optimisation. Application-aware filtering, TLS inspection, threat prevention, and rule cleanup for overgrown rulesets.
Performance Optimisation
Latency analysis, traffic shaping, QoS implementation, and WAN optimisation. Identifying and resolving bottlenecks in mission-critical application delivery.
Resilience & Failover
BGP failover design, cluster architectures, load balancing, and automated failover. Building infrastructure that survives component failures without service interruption.
Deep Protocol Expertise
Effective network security requires understanding protocols at the packet level — not just configuring vendor dashboards. Daniel's expertise spans:
- Routing & Switching: BGP, OSPF, EIGRP, MPLS, and SD-WAN — designing resilient, performant routing topologies
- Traffic Analysis: Deep packet inspection, NetFlow/sFlow analysis, and anomaly detection for threat identification
- Monitoring & Observability: SNMP, streaming telemetry, network performance monitoring, and real-time alerting
- Wireless Security: Enterprise Wi-Fi architecture, WPA3, rogue AP detection, and wireless IDS/IPS
- DNS & PKI: Secure DNS architecture, certificate management, and encryption infrastructure
IDS/IPS & Network Detection
Deploying and tuning intrusion detection and prevention systems that provide meaningful visibility without overwhelming alert volumes. Network Detection and Response (NDR) solutions that identify lateral movement, C2 communications, and data exfiltration in real time.
