Built-In Cyber Resilience

The landscape
Manufacturing has become the primary target for cyber disruption
The convergence of IT and operational technology has transformed what is possible on the factory floor. Cloud-connected Manufacturing Execution Solution (MES) platforms that coordinate production across continents. Industrial Internet of Things (IIoT) sensors that feed real-time data into predictive maintenance platforms. Remote engineering access that keeps specialist skills available across distributed sites. Digital supply chains where partners, logistics providers and systems share data continuously.
The same connectivity that makes these capabilities possible has fundamentally changed the risk environment. Manufacturing is now the most targeted sector for cyberattacks globally, accounting for 22% of all analyzed attacks in 20251. The volume of ransomware incidents rose 61% year-on-year, with operational downtime and supply-chain paralysis as the primary consequences2. Jaguar Land Rover’s 2025 cyber incident forced weeks of global production shutdowns — not a data breach, but an industrial stoppage.
The constraint is the security architecture itself.
Global manufacturers are simultaneously managing fragmented firewall estates across dozens of markets, enforcing policies that were defined centrally but implemented inconsistently, operating monitoring tools procured independently for different parts of the estate while trying to achieve a coherent view of threat posture across an environment that was never designed to be governed as one.
Manufacturing accounts for 71% of ransomware incidents across industrial sectors3. 77% of organizations claim to monitor east-west traffic, but 40% of that traffic lacks sufficient context for confident investigation, leaving nearly half of lateral movement incidents undetected.4 NIS2 in Europe, CMMC in North America and sector-specific frameworks across Asia-Pacific mean the regulatory consequences of a breach now compound the operational ones, and the compliance burden falls on teams already stretched by day-today operations.

The problem is the security architecture the tech runs on
Consistent threat detection, centralized policy enforcement and clear accountability are not features most manufacturing security environments were designed to deliver. That is precisely where resilience fails.
Fragmented security policies
Multiple regional providers and inconsistently applied controls create gaps that are difficult to identify and remediate at scale.
Limited OT visibility
Security teams lack a unified view across IT, OT and cloud environments, leaving threats to move laterally before detection
Slow incident response
Manual detection and remediation processes prolong the window between breach and containment, amplifying production impact.
Where GTT comes in
Built specifically for the complexity of global manufacturing networks
The approach
Why built-in cyber resilience Is an architecture argument, NOT a product selection
Manufacturers evaluating security typically begin with point solutions like firewalls, endpoint tools, remote access platforms, often procured separately and assembled across multiple vendors. This results in a functionally fragmented security posture with multiple management consoles, inconsistent policies and no unified view of risk.
The GTT Envision platform delivers an integrated security architecture that sits across all of it, providing unified threat visibility, policy control and compliance reporting from a single interface. This is the operational difference between a security program that requires constant internal coordination and one that maintains consistent protection, governance and response capability as a managed service.
| With Disconnected Point Products | With GTT Built-In Cyber Resilience |
|---|---|
| Multiple security vendors, each managing their own segment of the environment | A single partner with end-to-end security accountability — one SOC, one escalation path, one operations team |
| Security policies set regionally and enforced inconsistently across sites | Centralized policy control via GTT EnvisionCORE, enforced consistently across all GTT-managed network and security infrastructure |
| Threat visibility assembled from multiple dashboards with no single source of truth | Unified real-time threat analytics via GTT EnvisionDX — one accurate, current view across the global estate |
| OT and IT managed by separate teams with different tools and response processes. | Security monitoring across GTT-managed infrastructure with MDR log ingestion from third party IT and OT systems, coordinated through GTT's global SOC |
| Compliance evidence gathered manually from fragmented systems before audits | Continuous audit trails and compliance reporting available on demand through the GTT Envision Platform |
The solution
One integrated security architecture. One managed service.
GTT’s built-in cyber resilience is built on a single integrated architecture, delivering the threat protection, policy consistency and compliance visibility that distributed manufacturing operations require.
Unlike providers that aggregate point security products, GTT delivers security as a managed service embedded into GTT EnvisionCORE, covering IT, OT and cloud environments from a common architecture managed through the GTT Envision Platform. In environments where OT security expertise is scarce and legacy systems create persistent exposure, GTT’s global SOC provides the 24/7 coverage and OT-aware response capability that internal teams cannot maintain independently.
Core capabilities supporting manufacturing cyber resilience
The platform advantage
Unified security visibility and control across every site
The GTT Envision Platform delivers security governance without adding operational complexity. It adapts to the realities of each site, from a fully modernized cloud-connected facility to a legacy OT environment with limited change windows, while maintaining centralized policy and compliance oversight.
Real-time telemetry at every plant edge. Security events and performance deviations are visible as they occur, giving GTT’s SOC the data needed to detect and respond to threats rapidly.
Centralized policy orchestration and standardized change control. A security policy update made at headquarters propagates to every site simultaneously, eliminating the inconsistency that emerges when regional teams implement independently.
Executive-ready threat analytics, SLA trendlines, compliance evidence and audit-ready reporting across all locations. Security, operations and leadership teams share the same current view of risk posture, without manual reporting cycles.
The proof

Why GTT
Built for the security demands of global manufacturing
| Tier-1 Global Backbone | GTT Envision Platform | 7 Global SOC |
|---|---|---|
| GTT's top-ranked global IP backbone covers 400+ points of presence across six continents. Security services delivered over this infrastructure provide consistent, low-latency protection across every site, including markets where sourcing reliable, secure connectivity independently is operationally complex. Manufacturers do not need to manage separate carrier relationships or security monitoring arrangements in each country. GTT does. | The GTT Envision Platform is the operational difference between managing global security and simply owning tools. GTT EnvisionCORE enforces consistent policies across every site. GTT EnvisionEDGE detects anomalies at the plant edge before they affect production. GTT EnvisionDX provides real time threat analytics and audit ready compliance reporting for security teams, operations and leadership. Together, a manufacturer with facilities across multiple continents has one accurate, current view of its security posture. | GTT's global Security Operations Centers provide 24/7 monitoring, threat investigation and rapid response across IT, OT and cloud environments. SOC teams bring OT-aware expertise that most internal security functions cannot resource independently, covering ICS/SCADA protocols, industrial anomaly detection and production-aware incident containment. Internal IT and security teams retain strategic direction. GTT retains accountability for detection, response and performance. |
Most security providers can protect one environment reliably. The challenge that determines whether a manufacturing security transformation succeeds or fails is different: can a provider deliver consistent, managed security across hundreds of sites, across multiple continents, covering both IT and OT environments, with different legacy infrastructures, different regulatory requirements (NIS2 and GDPR in Europe, CMMC in North America, data-sovereignty requirements across Asia-Pacific) and different levels of on-site security capability, without the operational burden falling on the customer’s internal team?
This is the problem GTT is specifically built to solve. Three capabilities aligned to GTT’s core commitment to connect, secure and simplify combine to make that possible:

Next steps
Starting the conversation
Security is the foundation production continuity depends on. To strengthen your manufacturing cyber resilience:
Map the current security posture against operational risk: Identify which production systems, OT environments and cloud connected applications carry the highest exposure, and where current controls leave gaps.
Audit security vendor and tool complexity: Count the number of active security providers, monitoring tools and management consoles across the global estate. This is the coordination overhead a unified managed service removes.
Assess detection and response capability:: Evaluate how long it currently takes to detect and contain a security event across the network. This is one of the clearest measures of whether the current architecture can protect production at scale.
Engage GTT: Contact GTT to map Built-In Cyber Resilience to your manufacturing environment and establish the consistent, globally governed security foundation your operations require.

What is built-in cyber resilience?
A managed security architecture embedded into the network itself, not bolted on top. It delivers consistent threat protection, policy enforcement and compliance visibility across every site, IT environment and OT environment globally.
Why is manufacturing the top target for cyberattacks?
Because production downtime is expensive and attackers know it. 22% of all cyberattacks in 2025 targeted manufacturers. 71% of industrial ransomware hit manufacturing. Operational disruption, not data theft, is increasingly the goal.
