Uncompromising
Resilience.
An elite collective of Cisco CCIE engineers. We architect, audit, and stabilize the infrastructure of global enterprises. Built for massive scale. Engineered for absolute fault tolerance.
Schedule Architecture AuditThe Company
ZBF Systems was not established as a traditional, high-volume IT consultancy, nor do we operate under the standard Value-Added Reseller (VAR) model that prioritizes rapid hardware deployment over architectural integrity. We originated as a highly exclusive, closed collective of Senior Network Architects who recognized a catastrophic flaw in modern enterprise scaling.
"Massive corporate, financial, and government networks are constantly being engineered for immediate convenience, fundamentally sacrificing long-term resilience and impenetrable security."
Every single engineer operating within the elite ranks of ZBF Systems bears well over a decade of intensive, battlefield-tested experience, predominantly forged within the highly demanding, high-stakes environments of Cisco’s Global Technical Assistance Center (TAC), top-tier Service Providers, and classified government enclaves.
- Unmatched Pedigree: Forged in the fires of global P1 outages.
- Zero Implicit Trust: Security woven into the hardware ASIC level.
- Referral Only: Ensuring elite talent is never diluted across mass-market deployments.

SVC.01 Infrastructure Design
The cornerstone of any resilient digital enterprise is its initial architectural blueprint. At ZBF Systems, our Infrastructure Design service is a rigorous, deeply analytical process that entirely rejects cookie-cutter topologies in favor of bespoke, highly deterministic engineering. We initiate every design phase with an exhaustive top-down approach.
- Data Center: Spine-Leaf fabrics utilizing EVPN-VXLAN with Anycast gateways.
- Campus: Eradicating STP vulnerabilities by driving Layer 3 routing directly to the access edge.
- High Availability: Utilizing NSF, SSO, and BFD timers for sub-50ms convergence.
Methodology Executed
End-to-end execution of migrations and greenfield deployments. Conducted strictly by CCIE-level talent.
SVC.02 Deep Infrastructure Audits
Our Auditing process goes far beyond the superficial scope of standard vulnerability scanning. ZBF Systems executes an aggressive, forensic-level analysis of your entire network fabric, diving directly into the command-line interfaces, control-plane metrics, and hardware forwarding tables of every device in your topology.
"We actively hunt for the invisible, systemic architectural flaws that automated tools simply cannot detect."
Audit Parameters
Non-intrusive topology mapping, advanced BGP compliance checks, and hardware-level TCAM analysis.

SVC.03 Break/Fix Escalation
When mission-critical transit ceases and core infrastructure faces severe degradation, standard IT support tiers are entirely insufficient. Every millisecond of downtime equates to massive financial loss and operational paralysis. ZBF Systems provides elite Break/Fix Escalation services, deploying veteran CCIE engineers.
- Surgical Fault Isolation: Bypassing standard scripts to analyze BGP state machines in real-time.
- Carrier Engagement: Speaking directly with backbone engineers to force rapid ISP resolution.
Incident Execution
> Layer 1-7 forensic analysis. Direct engagement with carrier backbone engineers and on-the-fly protocol re-engineering.
Technologies
Enterprise Routing & Switching
Enterprise routing forms the absolute foundational bedrock of all global connectivity. ZBF Systems possesses unparalleled mastery over the complex routing protocols that drive the modern internet. We are experts in Border Gateway Protocol (BGP), meticulously manipulating attributes to engineer highly deterministic, predictable traffic flows.
- Advanced IGP: Highly tuned OSPFv3 and IS-IS hierarchies.
- Global Transit: MPLS backbones delivering isolated L3VPNs across continents.
- Resilient Switching: Cisco Nexus and Catalyst 9000 utilizing vPC and StackWise Virtual.
Incident Log
> INCIDENT 404-R: Mitigated massive broadcast storm and BGP route-leak. Transit restored in under 12 minutes.
Zero-Trust Security Perimeters
In the modern threat landscape, the concept of a hardened external perimeter protecting a "trusted" internal network is a dangerous relic. Malicious actors frequently bypass edge firewalls, exploiting implicit trust to move laterally. ZBF Systems engineers environments based strictly on Zero Trust Network Access (ZTNA).
"We decouple security policies from rigid IP addressing to seamlessly enforce access control globally."
- Identity Control: Cisco ISE enforcing strict 802.1X and dynamic VLAN assignment.
- Micro-segmentation: Utilizing Cisco TrustSec and Security Group Tags (SGTs).
- Line-Rate Encryption: MACsec (802.1AE) protecting physical fiber payloads.
Global Collaboration Suites
Enterprise productivity relies heavily on frictionless, high-fidelity real-time communication. Real-time voice and video traffic utilizing UDP relies on a continuous stream of packets; even minor latency can cause completely severed executive communications.
We engineer complex dial plans, global E.164 routing strategies, and seamlessly integrate legacy PBX environments using Cisco Unified Border Element (CUBE). We meticulously audit the entire network path ensuring DSCP Expedited Forwarding (EF) markings are strictly honored.
Deployment Profile
> Architected seamless migration of 15,000-user enterprise from Microsoft environments to resilient Cisco Unified Communications.
Solutions
High-Frequency Trading (HFT) Networks
In the aggressive arena of algorithmic quantitative finance, the standard metrics of network performance are irrelevant. We are engineering environments where success is dictated by cutting mere nanoseconds of latency from the wire.
- ASIC Acceleration: Cisco Nexus 3550 series bypassing traditional MAC learning.
- Absolute Sync: Precision Time Protocol (PTP IEEE 1588v2) architecture.
- Market Data Delivery: Optimized multicast routing via PIM Sparse Mode.
Global Data Center Interconnects
Connecting massive data centers across continents requires immense bandwidth, absolute encryption, and the highly complex ability to stretch Layer 2 domains across standard Layer 3 IP transit networks without introducing catastrophic loops.
"We design world-class DCI fabrics utilizing cutting-edge EVPN coupled with Virtual Extensible LAN (VXLAN) encapsulation."
This architecture allows virtual machines to vMotion between continents while retaining exact IP addresses, drastically reducing Disaster Recovery (DR) execution times over dark fiber DWDM systems.
Secure Government Enclaves
Architecting infrastructure for defense agencies and federal intelligence sectors requires absolute adherence to rigorous cryptographic standards. ZBF Systems is highly experienced in engineering fully air-gapped environments complying with NSA CSfC and FIPS 140-2/3 requirements.
- Nested Cryptography: IPsec VPN tunnels inside of line-rate Layer 2 MACsec.
- OOB Management: Strict TACACS+ authorized, physically isolated control planes.
- VRF-Lite Segmentation: Isolating distinct classification levels on shared core hardware.
Projects
Acquisition Consolidation
Following the multi-billion-dollar merger of three regional logistics giants, a Fortune 500 entity found itself paralyzed by a fractured IT infrastructure. The network was a nightmare of overlapping RFC1918 addresses and conflicting routing protocols spanning Cisco, Juniper, and Arista hardware.
Execution Result
Engineered complex VRF leaking and BGP redistribution. Migrated thousands of branches without a single minute of business downtime.
Ransomware Rebuild
In the wake of a catastrophic ransomware proliferation that brought down a national healthcare provider, ZBF Systems was emergency-airlifted to take direct control. The malicious actors had encrypted critical patient databases and hospital telemetry servers.
"We executed a total purge of the existing routing control plane, forcibly severing compromised peerings and rebuilding trust boundaries from scratch."
We safely restored critical medical applications and telemetry systems back online within 48 hours of deployment.
Next-Gen Campus SDA
A tier-1 global research university was struggling with a legacy network spanning 50 buildings and 40,000+ endpoints. The IT staff was overwhelmed by manually provisioning switch ports and managing sprawling VLANs causing broadcast storms.
- Fabric Deployment: Layer 3 IS-IS underlay with Software-Defined Access (SDA) overlay.
- Zero-Touch: Cisco DNA Center reducing switch provisioning time by 90%.
- IoT Security: Cisco ISE dynamically enforcing SGT policies to isolate rogue devices.
