What brings organizations here

Most enterprise network problems are not equipment failures. Equipment gets blamed because it is visible. The actual issue is a design that was never there, segmentation added as an afterthought, or infrastructure that grew without anyone asking what it would need to support five years out. By the time the symptoms are obvious, the root cause is structural and the fix requires more than a replacement cycle.

Hans Study, CISSP, works with organizations across Ontario and North America on the architecture problems sitting underneath the visible symptoms. Networks patched and extended over a decade without a coherent design. Segmentation that exists on paper but is not enforced. Remediation projects that need to happen in a live environment where taking the network offline is not an option.

TSG Labs sells no equipment and holds no reseller agreements. Platform recommendations reflect what the environment requires. Nothing else.

When to reach out

Architecture reviews make the most sense before a refresh cycle, before a significant infrastructure investment, or when recurring problems keep coming back after equipment replacements. Greenfield design is most valuable at the early design stage, before the architect and mechanical contractor have already constrained the options. Not every engagement is a formal project. Some IT teams need a second opinion on a specific design decision, or a direct answer on whether a vendor proposal makes sense for their environment.

Segmentation and Security Architecture

Segmentation that exists on paper but is not enforced is not segmentation. Zone architecture, inter-zone access control, and firewall policy design tied to compliance requirements including CMMC, ISO 27001, and NERC CIP where applicable.

Remediation and Network Restructuring

Most networks that need fixing cannot be taken offline to fix them. Phased remediation plans that sequence changes to minimize disruption, identify viable existing infrastructure, and reach a defensible architecture without a full replacement capital spend.

Technical Advisory for IT Teams

Some IT teams need an experienced external voice on a specific decision before committing to it. A second opinion on a vendor proposal. A direct answer on whether a proposed architecture makes sense for the environment. Short advisory engagements, no retainer, no minimum project size.

What platforms does TSG Labs work across?

Cisco, Aruba, Alcatel-Lucent Enterprise, Juniper, Fortinet, and Palo Alto Networks. Platform recommendations are based on fit for the environment. TSG Labs holds no reseller agreements and earns no margin on equipment. The recommendation reflects the requirements. Nothing else.

Does TSG Labs design networks for new facilities?

Yes. Greenfield engagements cover full architecture design including physical topology, segmentation, routing, wireless, and security architecture, coordinated with the physical security systems and compliance frameworks the network will need to support. Getting architecture guidance before construction starts is where the value is highest and the cost of changes is lowest.

Who provides independent network architecture consulting in Ontario?

TSG Labs, based in Ontario, provides vendor-agnostic network architecture consulting across Canada and the US. Hans Study, CISSP, works across government, defence, critical infrastructure, transportation, and enterprise environments. No equipment sales, no vendor relationships.
