Never trust, always verify — enforced
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
| Pillar (CISA ZTMM) | What it means | What RHC implements |
|---|---|---|
| Identity | Authenticate and authorize every user, per request | Phishing-resistant MFA, SSO, conditional access (Entra ID / Okta) |
| Devices | Only healthy, known devices reach resources | EDR, device posture, Intune / MDM compliance gates |
| Networks | Segment and encrypt; no implicit east-west trust | Micro-segmentation and ZTNA replacing flat VPN |
| Applications & workloads | Least-privilege access to every app and service | Per-app authorization, workload identity, brokered secrets |
| Data | Protect the data itself, everywhere it travels | Classification, encryption, DLP, and access logging |
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.
