Secure OT Without Perfect Visibility

How Frenos' Optica Bridges the OT Visibility Gap

The OT Security Visibility Challenge

Organizations managing critical infrastructure face a persistent challenge:
"How do we secure systems we can't fully see?"

This question becomes especially critical in Operational Technology (OT) environments where traditional IT scanning tools can disrupt essential processes, and deploying passive monitoring sensors across hundreds or thousands of locations simply isn't always feasible or scalable quickly.

Incomplete asset inventories aren't just a technical problem; they're a fundamental business risk that prevents organizations from:

• Quantifying their true security posture
• Making informed decisions about security priorities
• Allocating resources based on actual risk
• Demonstrating regulatory compliance with confidence
• Justifying security investments with concrete data

The Optica Solution: Beyond Traditional OT Visibility

Optica isn't another asset inventory tool or appliance. It's the OT security industry's first "tech-enabled rapid visibility service" designed specifically to eliminate the visibility gap that undermines effective security planning.

Here's what makes Optica different: By creating high-fidelity virtual representations of critical infrastructure, Optica enables what was previously impossible—comprehensive OT security analysis even without complete asset visibility.

Why this works: Anyone who's worked in OT knows these environments are built to specifications. Whether following OEM standards or internal blueprints, most sites share common devices, configurations, and architectures to ensure reliability and safety. Optica leverages this reality through templatized virtual representations, allowing security teams to quickly move past the visibility problem and focus on what matters; assessing security, prioritizing mitigations, and building proactive defenses.

Optica + Frenos Platform: Continuous OT Security Posture Management

When paired with the Frenos Platform, Optica transforms how organizations approach OT security across their entire infrastructure. This combination delivers capabilities previously unattainable in critical infrastructure environments.

The Foundation: Scalable OT Asset Intelligence Without Disruption

Optica provides what has long eluded OT security teams: scalable, comprehensive asset visibility. Using sophisticated modeling techniques on your existing OT datasets, Optica creates detailed representations of your network environment including:

• Hardware specifications and configurations
• Sample software inventories with version details
• Protocol implementations and communications pathways

Unlike traditional OT discovery tools that require extensive scanning or time-consuming sensor deployments, Optica builds this intelligence through a template-based approach that leverages existing knowledge while filling critical gaps.

The Transformation: From Static Data to Dynamic Security Insights

The Frenos Platform transforms Optica's asset models into a digital twin simulation environment. This is where static data becomes actionable intelligence through:

• Realistic attack path modeling across your entire infrastructure
• Adversarial simulation using advanced threat intelligence
• Architectural vulnerability assessment without touching production systems

The platform enables security teams to move beyond theoretical risk discussions to evidence-based analysis of how actual attacks could unfold across your specific environment—all without any packets, installs, or production impact.

The Outcome: OT Security Decision Intelligence

The true power of the Optica + Frenos ecosystem emerges in the actionable intelligence it provides:

• Complete OT Visibility Even Without Asset Inventory: Combine current visibility datasets with Optica's virtual assets based on your actual templates and configurations.
• Continuous Risk Assessment: Track whether your industrial environment's risk posture is improving or degrading over time.
• Prioritized Risk Reduction: Identify critical security improvements based on actual attack simulations, not generic findings lacking environmental context.
• Proactive Security Posture: Stop waiting for intrusions to trigger responses. Start focusing on mitigations that deter the most likely adversary tactics.
• Regulatory Compliance: Demonstrate due diligence with comprehensive documentation of risk assessments and mitigation planning which acts as evidence to meet regulatory requirements.

Breaking Through Traditional Security Limitations

The Optica + Frenos ecosystem transcends the limitations that have historically hampered critical infrastructure security:

• The Visibility Barrier: No more waiting for perfect asset inventory before conducting meaningful security analysis. Any future details from Asset Inventory tools can easily be added when available
• The Risk Quantification Challenge: Replace subjective assessments with simulation-based evidence of actual attack feasibility
• The Operational vs. Security Divide: Test security improvements without impacting operational systems
• The Compliance Documentation Burden: Generate comprehensive assessment documentation automatically through simulation

For the first time, security leaders can make informed decisions about protecting critical infrastructure without perfect visibility, without operational disruption, and without relying on generic advice that ignores their specific environment.

Immediate Value for Critical Infrastructure Operators

Organizations that benefit most from Optica include those with:

• Restricted scanning environments where traditional tools pose operational risks
• Hundreds or thousands of distributed locations
• Complex OT/IT convergence requirements
• Regulatory mandates for comprehensive security assessments
• Security teams struggling to scale visibility across industrial control systems

The Path Forward: Strategic Implementation

Organizations can follow a practical implementation path that delivers quick wins while building toward comprehensive security:

• Phase 1: Rapid modeling of critical segments to establish baseline visibility
• Phase 2: Data integration with Frenos for continuous OT security assessments
• Phase 3: Enterprise-wide deployment supporting proactive OT security

Conclusion: Building Security on a Foundation of Visibility

In today's OT threat landscape, "we don't have visibility everywhere" is no longer an acceptable answer. Frenos' Optica eliminates this obstacle by providing the comprehensive asset understanding required to confidently assess security posture across your OT environments.

For organizations that need to make critical OT security decisions today without waiting for perfect visibility tomorrow. Optica provides the strategic foundation for confident action.
