ZTNA


Zero Trust Network Access (ZTNA) is a security framework that ensures users and devices are authenticated and authorized before gaining access to applications and data. Unlike traditional VPNs, which grant broad network access, ZTNA enforces least-privilege access, allowing only the minimum permissions needed for a specific task.

How ZTNA Works

  • Identity-Based Access – Verifies user identity and device security posture before granting access.
  • Least-Privilege Model – Users can only access specific resources they are explicitly authorized to use.
  • Continuous Verification – Access permissions are dynamically adjusted based on user behavior and risk levels.
  • Micro-Segmentation – Isolates network resources to minimize lateral movement in case of a breach.
  • Cloud-Native Security – Protects applications and data regardless of whether they are hosted on-premises or in the cloud.

Why Businesses Need ZTNA

With the rise of remote work and cloud applications, traditional perimeter-based security models are no longer effective. ZTNA provides:

  • Enhanced security by reducing the attack surface.
  • Improved compliance with data protection regulations.
  • Better user experience with seamless, adaptive access.
  • Stronger defense against Ransomware, Phishing, and insider threats.

Delaney Computer Services (DCS) integrates ZTNA solutions into its cybersecurity offerings, by helping businesses implement a secure, modern access control strategy with solutions like OpenVPN's Cloud Connexa.
