Zero Trust Network Architecture (ZTNA) Implementation

Your Perimeter Is Already Gone, Let’s Redefine Trust

Advanced Network Infrastructure and Design Services

What Makes Intelligent Visibility Different?

Aligned to Standards, Built for Operations

We take the theory of Zero Trust and turn it into operational reality. Our projects are built on frameworks like NIST 800-207 and refined with hands-on engineering—from endpoint identity to cloud segmentation and enforcement.

  • Zero Trust is not a product. It’s a security architecture that spans identity, access, application visibility, and micro-segmentation.
  • We integrate with your existing infrastructure. That includes on-prem directory services, cloud IdPs, network firewalls, EDR, and monitoring platforms.
  • No lock-in or black box tooling. Our approach leverages APIs and open architecture, so you maintain control.

A Phased and Practical ZTNA Deployment Model

Phase 1: Discover & Design

The foundation of Zero Trust is visibility. We inventory users, devices, applications, and data flows to define your “protect surface”- the assets that actually matter.

  • Asset and identity discovery: Using tools and interviews, we catalog users, service accounts, SaaS apps, data flows, and endpoints.
  • Protect surface definition: We help you determine which applications and data sets require granular controls.
  • Risk and policy gap analysis: We assess your current controls against Zero Trust principles to find exposure points.

Phase 2: Pilot & Build

We start with a defined use case to validate policies, tools, and operational workflows before scaling.

  • Policy engine deployment: We integrate with your IdP (e.g., Azure AD, Okta) to enforce adaptive policies based on role, device, and context.
  • Micro-segmentation design: We use tools like Arista CloudVision, Cisco ACI, or host-based firewalls to isolate traffic.
  • Legacy and unmanaged device strategy: We create policies for BYOD, vendor, or non-agent-compatible systems without compromising posture.

Phase 3: Operationalize & Optimize

With the model validated, we scale access policies, improve automation, and refine rules based on live telemetry.

  • Full-scale policy rollout: Expand beyond the pilot to include broader users, applications, and data sets.
  • Continuous verification: Our Aegis team monitors for drift, anomalies, and policy misconfigurations in real time.
  • Ongoing policy refinement: Access policies evolve with user behavior, business goals, and new threats.

Key Capabilities Delivered by Intelligent Visibility

Capability Description
Micro-Segmentation We create secure zones around applications and workloads to isolate east-west traffic. Policies are enforced via platform-native controls or APIs- no rip-and-replace needed.

Continuous Verification

 Every session is evaluated in real-time based on user, device, location, behavior, and more. Access is revoked immediately if risk conditions change.
Legacy System Protection
 We design Zero Trust overlays for applications or users where agent deployment isn’t feasible, using reverse proxies or isolated VDI environments.
Third-Party Access Enablement Role-based access for vendors and contractors to specific apps or environments, without giving them lateral access to internal systems.
Cloud and Hybrid Integration Unified control across AWS, Azure, VMware, and on-prem- ensuring your cloud adoption doesn’t increase your attack surface.
Operational Readiness We integrate with existing logging, monitoring, and ITSM tools. All activity is auditable and policy-driven.
Performance Considerations Our architecture minimizes latency and avoids cloud bottlenecks. We maintain user IP visibility and avoid routing everything through a proxy choke point.

Use Cases We Commonly Solve

  • Hybrid Workforce Enablement: Enable secure, high-performance access for remote users without VPN bottlenecks or management overhead.
  • Third-Party Contractor Access: Grant partners application-specific access while keeping the core network completely hidden.
  • Merger & Acquisition Integration: Provide new teams or acquired companies with secure access to shared systems without full network integration.
  • Compliance Hardening: Achieve tighter control over regulated data (e.g., HIPAA, PCI) through auditable access policies and segmentation.

Our Operational Model

We don’t just advise or hand off documentation. We deliver:

Defined-scope implementation projects

grounded in engineering.

Co-managed services

that integrate into your environment and toolchains.

Hands-on support from architecture to run-state

through Aegis services.

Flexible tools

that scale with your infrastructure- not locked to a single OEM.

Measurable Outcomes That Matter

We track progress with meaningful KPIs:

Security & Risk Metrics

  • Reduction in exposed applications on public IP space
  • Mean time to detect and respond (MTTD/MTTR) for lateral movement
  • Decrease in credential abuse and unauthorized access

Operational Efficiency

  • Reduced support overhead from VPN and identity access issues
  • Shortened onboarding timelines for new users or apps
  • Lower alert fatigue via policy-driven enforcement and automation

Business Enablement

  • Improved access control across hybrid and multi-cloud
  • Faster go-to-market for digital services requiring secure access

Documented compliance alignment for audits and risk review

Why Start with iVi?

You need more than a checklist or slide deck. Intelligent Visibility delivers Zero Trust as a secure, operational, and optimized service- with the engineering capability to back it up and the strategic perspective to ensure alignment with business goals.

Let’s start with one access challenge. We’ll help you solve it the right way, then scale from there.

Frequently Asked Questions

How does Zero Trust improve performance for remote workers?

ZTNA enables direct, secure access to applications without routing all traffic through a central VPN gateway. This reduces latency, improves user experience, and eliminates single points of failure. It also allows access decisions to be made at the edge, closer to the user.

What if I have legacy systems or unmanaged devices?

We build strategies for protecting those, too. If an agent can’t be installed, we may use reverse proxies, browser-isolation, or access through hardened VDI environments. The key is to define acceptable risk-  and control it with contextual access policies.

Can Zero Trust help with compliance?

Yes. Zero Trust provides detailed logging, role-based access controls, and audit-ready policy enforcement. Whether you’re facing HIPAA, PCI-DSS, or CJIS requirements, we align your environment to those standards with measurable controls and traceability.

What makes iVi different from a typical security reseller?

We’re not resellers-first-  we’re engineers-first. We don’t just sell platforms; we design, build, and run integrated Zero Trust solutions that align with your business outcomes. Our co-managed model ensures long-term visibility, flexibility, and support after the initial rollout.

How long does a typical ZTNA implementation take?

We move fast, but responsibly. Most clients see meaningful impact within 60–90 days, starting with a targeted use case (like remote access to one critical app or securing third-party access). Full rollout timelines vary based on scope, but our phased approach avoids unnecessary risk or user disruption.

Can I see a demo or talk through a specific use case?

Absolutely. We tailor every discussion to your environment- whether it’s enabling secure remote access, onboarding a new business unit, or protecting sensitive cloud workloads. Schedule a working session with one of our architects to see how we’d approach it.
