Core capabilities

Focused on the infrastructure decisions that matter most.

Vector Six focuses on enterprise network and infrastructure transformation where architecture quality and execution discipline directly affect resiliency, operational simplicity, and long-term scalability.

WAN and edge

Enterprise WAN & Edge Transformation

Modernize WAN architecture for cloud access, distributed sites, and security policy control across branch and edge environments.

  • SD-WAN and SASE architecture
  • Branch modernization and resiliency planning
  • Connectivity and carrier strategy
  • Pilot design, migration sequencing, and cutover support
Data center

Data Center Fabric Architecture

Design modern data center fabrics using scalable Layer 3 patterns, EVPN / VXLAN overlays, Cisco ACI, and NDFC-aligned operational models.

  • Spine-leaf architecture and segmentation
  • Multi-site design and failure-domain planning
  • Operational simplification for large fabric environments
Cloud and security

Hybrid Cloud & Security Architecture

Network architecture for hybrid and multi-cloud connectivity, cloud transit design, Zero Trust segmentation, and identity-aware access patterns.

  • Cloud on-ramp and interconnect architecture
  • Segmentation strategy across on-prem and cloud
  • Security architecture aligned to application flows
Delivery model

Architecture first. Execution when it counts.

Most engagements begin with design clarity. Once the target architecture is defined, Vector Six can stay involved to guide internal teams, support implementation partners, or lead technical delivery where needed.

01

Architecture Assessment

Review the current environment, identify structural weaknesses, validate design assumptions, and establish where operational complexity is creating risk.

02

Target Architecture & Roadmap

Define the future-state architecture, create phased modernization plans, and align technical priorities to business constraints, staffing realities, and implementation sequence.

03

Transformation Execution

Lead or support migration, build, validation, and cutover activities so the architecture is implemented the way it was intended, not diluted during delivery.

Engagement options

How organizations typically work with Vector Six.

Vector Six engagements often start with architecture leadership and continue through implementation. Some clients need an embedded architecture partner. Others need focused leadership for a defined transformation initiative.

Ongoing advisory

Fractional Network Architect

Ongoing architecture leadership embedded with internal infrastructure teams.

  • Architecture guidance for network and infrastructure initiatives
  • Design reviews before major production changes
  • Technical decision support for engineering teams
  • Connectivity and carrier strategy where required
  • Architecture guardrails for in-flight projects
Project delivery

Project-Based Transformation

Architecture-led delivery for complex infrastructure initiatives where design quality and execution both matter.

  • Target architecture design and migration planning
  • Implementation planning and technical governance
  • Engineering guidance during deployment and cutovers
  • Coordination with vendors and connectivity providers
  • Validation, troubleshooting, and operational handoff
Best fit:

Organizations preparing for major infrastructure changes who need clear architecture guidance and experienced support during implementation.

Best fit:

Organizations under pressure to reduce infrastructure costs, simplify environments, or modernize platforms but without a clear architectural path forward.

Representative work

Examples of the kind of infrastructure change Vector Six supports.

The exact scope varies by environment, but the common pattern is the same: high-consequence architecture decisions, multi-stakeholder coordination, and implementation risk that needs strong technical control from design through delivery.

Financial services

40-site SD-WAN modernization

Architecture leadership for MPLS replacement, DIA adoption, segmentation strategy, secure internet access, and SaaS path optimization across a distributed branch environment.

  • Migration sequencing across dozens of sites
  • Overlay design and branch resiliency planning
  • Reduced dependency on legacy transport models
  • MRC savings totaling ~950k/year
Healthcare

Large-scale SD-WAN architecture

Designed a resilient hub-and-spoke architecture spanning multiple data centers, regional hubs, and a broad site footprint where uptime and predictable routing behavior were critical.

  • Regional hub design for growth and failover
  • Segmentation and policy consistency across sites
  • Built for distributed clinical operations
Cloud networking

Global Azure network rebuild

Re-architected cloud networking across multiple regions with hub-and-spoke design, segmentation, and inter-region routing aligned to enterprise application and access requirements.

  • Regional architecture with clear routing and security domains
  • Multi-region connectivity and policy control
  • Integrated branch access into the cloud design with SD-WAN
Data center and cloud

Cloud on-ramp modernization

Replaced legacy cloud connectivity patterns with modern interconnect architecture designed for higher throughput, lower latency, and more predictable cloud access.

  • Redundant on-ramp design
  • Improved path efficiency to cloud platforms
  • Simplified long-term cloud connectivity model
  • MRC savings of $45k/mo.
Why clients bring Vector Six in

Because infrastructure transformation usually fails at the architecture layer first.

Most organizations do not need more generic IT support. They need better design decisions, stronger technical governance, and experienced leadership during periods of major infrastructure change.

Complexity Simplify environments that have grown through years of one-off decisions.
Risk Reduce the chance of expensive design mistakes before implementation starts.
Scale Build infrastructure that can support future growth without repeated redesign.
Execution Keep the architecture intact through migration, build, validation, and cutover.
About Vector Six

Architecture experience applied to real infrastructure work.

Vector Six is an SBA-certified Veteran-Owned Small Business led by Craig Rivenburg, Founder and Chief Architect. The firm was built to give organizations access to architecture expertise in network, data center, cloud, and security domains without defaulting to generic consulting models.

Approach

Design quality comes first.

Vector Six leads with architecture because poor design decisions compound over time. The work focuses on creating practical target-state environments that internal teams can actually operate and extend.

Positioning

Built for complex enterprise environments.

The firm is best suited for organizations modernizing WAN, campus, data center, cloud, or security architecture where the technical stakes are high and design shortcuts become expensive later.
