Zero-Trust Architecture

Zero-Trust replaces the network perimeter with per-request verification: every user, device, and workload is authenticated, authorized, and continuously evaluated before it touches a resource. RHC Solutions designs and implements Zero-Trust across identity, devices, network, applications, and data — phishing-resistant MFA, micro-segmentation, ZTNA, and least-privilege access — aligned to NIST SP 800-207 and the CISA Zero Trust Maturity Model.

Most breaches succeed by moving laterally after a single foothold. Zero-Trust removes the implicit trust that makes that possible: no user or device is trusted by default, access is granted per session and scoped to the minimum required, and it is revoked the moment device posture or risk signals change.

What we deliver

Identity-First Access

Phishing-resistant MFA, SSO, and conditional access on Microsoft Entra ID or Okta. Risk-based policies evaluate user, device, and location on every request.

Micro-Segmentation & ZTNA

Replace flat VPN access with Zero-Trust Network Access — per-application, identity-aware tunnels and east-west segmentation that contain lateral movement.

Device & Workload Trust

EDR, device posture, and Intune/MDM compliance signals gate access; workloads get least-privilege identities and brokered, short-lived secrets.

Data Protection & Continuous Verification

Classification, encryption, and DLP applied to the data itself, with logging and analytics that re-verify trust continuously and feed your SIEM.

The five Zero-Trust pillars — and what we implement

Where Zero-Trust pays off

  • Remote and hybrid workforces that have outgrown VPN
  • Mergers and acquisitions needing fast, safe access integration
  • Regulated data (SOC 2, ISO 27001, HIPAA, PCI DSS) requiring least-privilege evidence
  • Containing ransomware and insider lateral movement

How we engage

We start with a Zero-Trust maturity assessment against the CISA model, then map your identities, devices, applications, and data flows. From there we sequence a phased rollout — quick wins first (phishing-resistant MFA, conditional access, and ZTNA for the riskiest access), then micro-segmentation and data controls — so risk drops at every step without disrupting the business.

> FAQ

Zero-Trust Architecture — FAQ

What is Zero-Trust Architecture?
Zero-Trust is a security model that removes implicit trust from the network. Rather than trusting anything inside a perimeter, it authenticates and authorizes every user, device, and workload on each request, grants least-privilege access, and continuously verifies. It is defined in NIST SP 800-207.
Is Zero-Trust a product we buy?
No. Zero-Trust is an architecture and a set of policies implemented across your existing identity, endpoint, network, and data tools. RHC designs the model and implements it with platforms you likely already own — such as Microsoft Entra ID, Intune, and EDR — plus ZTNA where flat VPN access needs replacing.
How long does a Zero-Trust rollout take?
The first risk-reducing wins — phishing-resistant MFA, conditional access, and ZTNA for high-risk access — typically land in weeks. Full maturity across all five pillars is a phased program over months, sequenced so each phase delivers measurable risk reduction.
How does Zero-Trust relate to compliance?
Least-privilege access, strong authentication, segmentation, and continuous logging are direct evidence for SOC 2, ISO 27001, HIPAA, and PCI DSS. A Zero-Trust program produces much of the access-control and monitoring evidence auditors ask for.
