Uncompromising Resilience.
An elite collective of Cisco CCIE engineers forged in the Global Technical Assistance Center (TAC). We architect, audit, and stabilize the infrastructure of global enterprises.
The Team
ZBF Systems was not founded as a traditional IT consultancy. We originated as a closed collective of Senior Architects who recognized a critical flaw in modern enterprise scaling: networks were being built for convenience, not for resilience.
Every engineer within our ranks bears over a decade of intensive, battlefield experience within Cisco's Global Technical Assistance Center (TAC). We have engineered, audited, and secured the most complex, mission-critical topologies on the planet.
Today, we operate globally, strictly by referral. We do not patch vulnerabilities; we design environments where they cannot exist. From dark fiber routing to cryptographic boundaries, we engineer bespoke digital fortresses for organizations whose data and uptime dictate the global market.

SYS.01 Infrastructure Design
Bespoke, enterprise-grade architectures. We engineer highly available routing topologies, secure perimeters, and seamless collaboration suites built for absolute scale and fault tolerance.
Methodology
End-to-end execution of complex migrations and greenfield deployments. Conducted strictly by CCIE-level talent, ensuring minimal operational friction and adherence to strict Cisco Validated Designs.
SYS.02 Deep Infrastructure Audits
Exhaustive assessments of existing network fabrics. We identify spanning-tree vulnerabilities, asymmetric routing flaws, and critical security gaps before they result in catastrophic downtime.
Methodology
Non-intrusive topology mapping, advanced configuration compliance checks, and strict packet-flow analysis to uncover hidden routing loops and cryptographic bottlenecks.
SYS.03 Break/Fix Escalation
Rapid fault isolation driven by ex-TAC veterans. When critical infrastructure experiences severe degradation, our engineers bypass standard troubleshooting tiers to stabilize your network instantly.
Incident Execution
> Immediate layer 1-7 forensic analysis. Direct engagement with carrier backbone engineers and on-the-fly protocol re-engineering to restore transit globally.
Architectural Focus
Enterprise Routing & Switching
The foundation of global enterprise relies on packet transit that never fails. We architect and deploy highly resilient Campus and Data Center networks, leveraging advanced BGP engineering, MPLS transit, and multi-vendor interoperability.
Deployment Profile :: Interoperability
> Unified fragmented multi-vendor routing during acquisition. Redistributed routes between legacy Juniper cores and new Cisco backbone; zero packets dropped.
Incident Log :: Routing Failure
> INCIDENT 404-R: Mitigated broadcast storm and BGP route-leak isolating European DC. Rogue switch isolated; transit restored in 12 minutes.
Zero-Trust Security Perimeters
Security is no longer a border; it is woven into every endpoint. We conduct exhaustive audits and engineer environments where implicit trust is eliminated, enforcing granular segmentation across the entire enterprise fabric.
Deployment Profile :: Migration
> Migrated from legacy Palo Alto to fully unified Cisco Firepower. Integrated Cisco ISE for identity-based control across 200+ branches.
Incident Log :: TrustSec Breach
> INCIDENT 892-S: Resolved weekend TrustSec misconfiguration dropping payment gateway traffic. Policy clash identified; transaction flow restored instantly.
Global Collaboration Suites
Enterprise productivity requires frictionless, high-fidelity communication. We deploy, harden, and migrate massive Cisco Unified Communications (CUCM) ecosystems integrating secure voice and video suites.
Deployment Profile :: Migration
> Architected seamless migration of 15,000-user global enterprise from Microsoft environments (Teams/Skype) to resilient Cisco Unified Communications and Webex suite.
Incident Log :: Media Degradation
> INCIDENT 112-C: Resolved latency and call drops for exec endpoints. Re-engineered QoS boundaries across transatlantic media flow.
