Approved design inputs
The security architect supplies access diagrams, segmentation rules, device requirements and the policy version to implement. Record who may approve a change and how an exception is escalated.
Approved architecture to field execution
Zero Trust Network Design and Deployment
SRS Networks turns an approved zero trust network design into a defined site infrastructure deployment. The security architect owns access policy and exceptions; SRS coordinates the assigned installation, configuration checks and evidence needed for a documented handoff.
For a branch rollout, agree which devices enforce policy, which application paths must work and who approves an exception. Those decisions become the installation standard and pilot test plan.

SRS Networks is a nationwide infrastructure deployment contractor headquartered in South San Francisco, California, delivering enterprise site projects across the 48 contiguous states, Alaska, and Hawaii since 1996. In-house project leads coordinate field execution, West Coast and East Coast staging facilities, and site records in the Project Command Center.
Keep design authority connected to the field work
Zero trust involves identity, devices, applications and operating policy as well as network infrastructure. Scope the portion your field program must deliver, then name the teams responsible for the remaining dependencies before scheduling site work.
Site readiness and inventory
Check the installed switching and firewall estate, available ports, power, pathways and management access. The designer decides which equipment meets the required features and which must change.
Deployment and cutover
Stage the approved equipment, coordinate the work window and execute assigned configuration changes. Capture the installation record and retain a usable rollback path for the agreed stop conditions.
Validation and ownership
Test the approved allowed and denied paths with the application owners. Deliver results and exceptions to the security owner, then transfer operations to the named team.

Sample design-to-deployment responsibility matrix
This sample shows how to remove ambiguous handoffs. The signed project scope assigns the actual people, deliverables and acceptance criteria.
| Workstream | Record to agree | Responsible owner |
|---|---|---|
| Access and identity policy | Approved policy version and test identities | Customer security architect / identity team |
| Physical site readiness | Power, rack, pathway and equipment readiness record | Site owner with SRS field lead |
| Assigned installation | Equipment inventory, port map and configuration references | SRS deployment lead |
| Pilot acceptance | Allowed/denied path results and exception decisions | Customer security and application owners |
| Continuing operation | Logging destination, support contacts and response scope | Named operations team |
NIST SP 800-207 explains zero trust architecture and deployment concepts. It treats trust decisions as resource- and policy-based; installing new network equipment alone does not establish that operating model. Architecture, identity and security operations work must have explicit owners. NIST SP 800-207: Zero Trust Architecture.

Questions to settle before deployment
What is zero trust network design?
Zero trust network design defines how access to resources is evaluated using identity, device and policy context, rather than granting trust solely because a connection is on an internal network. NIST SP 800-207 describes the architecture and deployment concepts. A field installation implements assigned parts of that design; it does not, by itself, establish a complete zero trust program.
Where does SRS fit in a zero trust rollout?
SRS scopes the site infrastructure and deployment work needed to execute the approved architecture. That can include cabling, switching, firewall installation, assigned segmentation changes and connectivity validation. Your security architect owns the overall access model and approves policy, exceptions and acceptance.
Does zero trust require replacing every switch and firewall?
Replacement depends on the required enforcement features, capacity, support status and the approved architecture. Inventory the existing equipment and configuration before deciding what can stay. Record compatibility gaps and the responsible designer's decision instead of assuming a wholesale replacement or universal reuse.
What belongs in the design-to-deployment handoff?
Provide the approved network and access diagrams, device inventory, segmentation and routing requirements, identity dependencies, change windows and rollback plan. Name the design authority and the operations team that will receive the system. Each site also needs its own readiness and exception record.
How should segmentation be accepted during a pilot?
Test representative allowed and denied paths against the approved policy, including the applications that must keep working. Record the source, destination, configuration version, result and unresolved exceptions for each agreed test. The security owner reviews the evidence and authorizes expansion to later sites.
Who owns identity, device posture and ongoing monitoring?
The work order names the identity, endpoint and security operations owners and any configuration work assigned to SRS. These functions need operating processes beyond the physical installation. Continuing monitoring or policy administration is a separately defined responsibility, not an automatic result of the field rollout.
Does the project certify compliance or prevent every breach?
No. Installation and test records document the work performed and the conditions tested; they are not a compliance certification or a guarantee against compromise. The appointed assessor and security owner decide which evidence satisfies their program and which gaps remain.
Can SRS support an integrator's multi-site zero trust program?
Yes. SRS can execute the defined field scope behind an integrator's approved design across the 48 contiguous states, Alaska, and Hawaii. Send the site list, equipment standard, acceptance requirements and schedule to partners@srsnetworks.com so design responsibility, field work and support handoff can be priced clearly.
Scope the field work behind your approved design
Send your site list, approved architecture, equipment standard and intended schedule. SRS will map the installation work, prerequisites, pilot evidence and handoff requirements with your design team.
