The OT Security Crisis:
You Can't Defend What You Can't See

Industrial networks face an unprecedented security crisis. With 78% of industrial network devices having known vulnerabilities (including 46% running deprecated firmware that can't be patched and 32% operating with unpatched vulnerabilities) and 83% of OT leaders reporting security breaches in the past three years, the threat landscape has never been more dangerous. Yet only 30% of organizations report 100% visibility of their OT systems, while 62% have visibility of three quarters of their systems, leaving most with critical blind spots across their infrastructure. The situation is accelerating: 73% of organizations experienced OT intrusions in 2024 alone, up from 49% the previous year. The financial impact is staggering, with 45% of organizations reporting losses exceeding $500,000 and 49% experiencing more than 12 hours of operational downtime.

The scale of this challenge is reflected in market projections: the global OT security market is expected to grow from $27 billion in 2025 to $122 billion by 2034. With 24% of organizations forced to shut down operations due to cyberattacks and 75% of OT attacks beginning as IT breaches, organizations can no longer afford visibility gaps or fragmented security approaches.

The Impossible Choice

Most organizations face these painful trade-offs:

Security OR Accessibility

Lock down systems and lose operational efficiency, or maintain access and expose vulnerabilities

Multiple Vendors OR Gaps

Manage complex integrations between disparate security tools, or accept coverage gaps

On-Site OR Remote

Send technicians for every issue at high cost, or risk unsecured remote access

Compliance OR Operations

Meet security requirements and slow operations, or maintain speed and risk violations

The Tosi Platform: Purpose-Built for OT

Tosi's Cyber Physical Systems platform eliminates this impossible choice with a purpose-built OT cybersecurity ecosystem that seamlessly connects, protects, and controls your entire operational network from any location—without compromising security or operational efficiency.
