Enterprise Network Engineering & SD-WAN Management

We design and deploy secure network architectures. Structured fiber WAN connections, Fortinet firewalls, and SD-WAN cloud integrations.

Enterprise Business Challenges

Modern business issues we encounter and solve.

As corporate operations scale, network downtime directly halts productivity. Insecure wireless connections, unmanaged switching switches, and outdated firewall configurations create vulnerabilities that invite cyber attacks and malware scripts. For a business with multiple branch offices, a single network outage can sever database access and block point-of-sale systems.

We engineer secure enterprise networks built on zero-trust architectures. We specify and configure Cisco and Fortinet hardware, design physical structured fiber runs, partition VLAN channels, and deploy software-defined wide area networks (SD-WAN) to secure your operations.

01 / CHALLENGE

Unscheduled Network Outages

Lack of redundant link systems means a single fiber break severs all connection, causing costly business downtime.

02 / CHALLENGE

Firewall Security Vulnerabilities

Outdated firewall rules allow external scanning scripts to probe internal server databases, risking sensitive records.

03 / CHALLENGE

Poor Branch Connectivity

Traditional WAN connections struggle to sync data between remote offices and main servers, creating latency.

Martelo's Architectural Solution

How our engineering team resolves system friction.

We design resilient, secure enterprise network topographies and zero-trust firewall configurations.

Our network engineers audit your physical site and logical systems, mapping out structured fiber plans and switch configurations. We segment your network into distinct virtual channels (VLANs), separating public visitor Wi-Fi from secure corporate servers.

We deploy advanced Fortinet and Cisco next-generation firewalls. We configure deep packet inspection, secure virtual private networks (VPNs) for remote workers, and block unauthorized ports to prevent intrusion.

To secure multi-site companies, we configure SD-WAN architectures. This technology routes traffic dynamically across fiber, LTE, and microwave connections, ensuring connection redundancy and zero outages.

Client Case Study

Real outcomes for real enterprise clients.

PROJECT SUMMARY

Redundant SD-WAN for Multi-Branch Retailer

Business Challenge

Frequent fiber cuts in southern Johannesburg isolated retail branches, halting card transactions.

Our Solution

Implemented Fortinet SD-WAN failovers routing traffic automatically to backup LTE links on outage.

Quantitative Outcome

Outage downtime dropped to 0, card transaction uptime rose to 100%, secure VLAN traffic isolated.

Technology Stack: Fortinet firewalls, Cisco switches, LTE link redundancy

Frequently Asked Questions

Common inquiries regarding our Enterprise Network Engineering & SD-WAN Management services.

Q: What is the advantage of SD-WAN over legacy MPLS?

A: SD-WAN routes traffic dynamically using standard broadband and LTE, offering the same reliability as legacy MPLS networks at a fraction of the cost.

Q: How does network VLAN segmentation protect our data?

A: VLANs isolate network traffic. If a guest device on the visitor Wi-Fi is compromised, the malware cannot cross into the secure VLAN hosting your accounting databases.
