Why Are VPNs and Jump Servers Being Replaced in OT & ICS?

A better way to securely remote access for ot and ics
VPNs and jump servers were not designed for modern industrial cybersecurity or compliance.

The Old Way: VPNs and Jump Servers

  • Broad network access creates unnecessary exposure
  • Shared or privileged accounts limit accountability
  • Minimal session visibility and incomplete audit evidence

The Modern Way: Xona Zero Trust Access

  • Identity-based access to specific assets
  • No direct user-to-network connectivity
  • Full visibility with real-time monitoring and recording

What Challenges are OT Teams Facing with Legacy Remote Access

The Status Quo Slows Operations and increases risk

Legacy remote access tools create operational drag and compliance overhead.
  • Slow vendor onboarding and manual access workflows
  • Limited proof of actions during audits and investigations
  • Performance issues when accessing ICS systems
  • Hard to manage access rules across internal and external users

Frequently Asked Questions for Secure Remote Access

Why is secure remote access becoming a top priority in OT and critical infrastructure?

Remote operations are increasing across industrial environments and organizations must enable remote maintenance and vendor access without exposing critical systems. Identity-based Zero Trust access is now essential for protecting ICS assets, ensuring uptime, and reducing cyber risk.

Why are VPNs and jump servers no longer sufficient for OT remote access?

These tools were designed for IT networks. They provide broad network access, rely on shared accounts, and offer limited visibility into user actions. Modern OT cybersecurity frameworks require identity-bound access, asset-level segmentation, and complete session evidence.

What does Zero Trust remote access mean for OT and ICS environments?

Zero Trust in OT eliminates implicit trust between users and critical assets. Access is granted only to the specific systems required for a task with full monitoring and recording which reduces cyber risk and aligns with modern OT security standards.

What market trends are accelerating adoption of modern secure remote access?

Drivers include increased digitization, third-party reliance, rising ICS cyber threats, updated TSA and NERC CIP requirements, EU NIS2 directives, and the need to reduce operational overhead created by legacy access tools.

What differentiates leading secure remote access platforms?

Leaders provide identity-based least privilege access, eliminate network exposure, deliver full session visibility, support ICS performance needs, integrate with SOC workflows, and simplify compliance with audit-ready evidence.

How is secure remote access evolving over the next three to five years?

OT environments will adopt Zero Trust architectures, require identity-level evidence for audits, automate vendor access workflows, integrate remote access with SOC platforms, and phase out VPN based architectures in favor of secure browser based access.

Why is visibility into remote sessions now essential for OT cybersecurity and compliance?

Regulators, insurers, and security teams require proof of who accessed which assets and what actions were taken. Full session logging and recording provide accountability, support investigations, and create audit-ready evidence.
