Take Back CONTROL of User Access to Your Critical Systems

The Cost of Waiting

Why You Need to Take Back Control of User Access Now!

The Risk is Growing – Why Waiting is No Longer an Option

Cyber threats targeting critical infrastructure are increasing at an alarming rate. Attackers and nation-states are exploiting weaknesses in remote access, outdated VPNs, and fragmented identity management, leading to costly and disruptive breaches. The data speaks for itself:

  • 71% of major OT cyber-attacks leveraged remote services as an entry point.1
  • U.S. utilities saw a 70% increase in cyberattacks in 2024 compared to 2023.2
  • Dragos reports an 87% surge in ransomware attacks on industrial environments, with a growing focus on disrupting OT operations.

Every day you delay taking action, attackers become more sophisticated, and your organization remains vulnerable. Critical infrastructure operators must acknowledge that cyber adversaries are actively targeting remote access systems, identity controls, and unmonitored user sessions to infiltrate networks and disrupt operations.

Beyond the security risks, regulatory compliance is tightening, and failure to comply with mandates like NERC CIP, IEC 62443, and TSA Security Directives can lead to steep fines and even operational shutdowns. The message from regulators is clear: secure user access is no longer optional—it’s an operational imperative.

By taking action now, organizations can close these security gaps, eliminate unnecessary risks, and ensure compliance before it’s too late. Waiting increases the likelihood of a breach, a costly compliance violation, or an operational disruption that could have been prevented.

The True Cost of Delaying Action

Delaying the implementation of robust user access controls exposes organizations to significant financial, operational, and reputational risks.

Financial Costs:

  • Escalating Breach Expenses: The global average cost of a data breach reached $4.88 million in 2024, marking a 10% increase over the previous year. Cyberattacks cost energy and utility companies $4.72M per incident.4
  • Regulatory Fines and Legal Actions: Non-compliance with cybersecurity mandates such as NERC CIP, IEC 62443, and TSA Security Directives can lead to substantial fines and legal repercussions.

Operational Costs:

  • Downtime and Disruptions: Inadequate user access controls can result in system downtime, operational disruptions, and decreased productivity.
  • Delayed Responses: Inefficient access controls can slow down incident response times and hinder timely maintenance, exacerbating operational challenges.

Reputation Damage:

  • Loss of Trust: Customers, partners, and regulators may lose confidence in organizations that fail to protect their critical systems or fail to demonstrate regulatory compliance, leading to diminished business opportunities and market share.

Proactively securing user access is essential to avoid these escalating costs and maintain operational integrity.

The Fastest Way to Secure User Access and Achieve Compliance

Secure Access is the #1 Cyber Priority in Critical Infrastructure

And Xona Can Help You Take Back Control of Your User Access for Critical Infrastructure in Under 1 Hour!

Introduction – Why Controlling User Access to Critical Systems is So Crucial

In today’s rapidly evolving threat landscape, user access control is the single most important, foundational cybersecurity priority for critical infrastructure owners and operators. Attackers continue to exploit weaknesses including legacy remote access mechanisms, and the consequences are severe. A few indicative statistics of this priority include:

Remote services were the primary attack vector in 71% of major cyber-attacks on OT environments.1

Ninety one percent (91%) of security professionals express concerns about VPNs compromising IT security.2

These statistics highlight a harsh reality—outdated access solutions like VPNs and jump servers are no longer sufficient to protect critical infrastructure. Attackers exploit gaps in identity verification, authentication, session controls, and open network access, leading to ransomware, system breaches, and operational downtime.

Organizations that lack centralized control over user access expose themselves to increased cyber risk, regulatory penalties, and inefficiencies that threaten operations. The solution? A modern, purpose-built critical infrastructure approach to secure access.

This blog explores what it truly means to take control of user access, outlines the key steps, and explains why Xona is the obvious choice in secure access for critical infrastructure.

What Does It Mean to Control User Access?

Taking control of user access means moving beyond legacy, fragmented access solutions and implementing a centralized, identity-based approach designed specifically for critical infrastructure environments. Without full control, organizations remain vulnerable to unauthorized access, operational inefficiencies, and regulatory penalties.

Before and After: The Risks of Poor Access Control
