You see the alarming headlines every day. Ransomware attacks surge across industrial sectors. Operational technology (OT) environments remain exposed. Manufacturing now accounts for 22% of all analyzed cyberattacks globally. This makes it the most targeted sector according to BitSight in 20251.
Ransomware incidents across the industry rose 61% year-on-year based on KELA data2. When these attacks land, they freeze supply chains and cost real money. Jaguar Land Rover’s 2025 cyber incident forced weeks of global production shutdowns3. That event caused a massive industrial stoppage.
Most headlines miss the core issue. The threat landscape simply exists. The real vulnerability stems from the security architecture sitting underneath it. By rethinking your approach to manufacturing cybersecurity, you can protect your production lines and safeguard your bottom line.
The real vulnerability is structural
Most global manufacturers built their security posture piece by piece instead of designing it as a single governed system. You might have a firewall estate in one region and a remote access tool in another. Your teams define policies centrally but enforce them inconsistently. This creates a security program that operates as a collection of loosely connected parts.
This fragmentation has measurable consequences. Manufacturing accounts for 71% of ransomware incidents across all industrial sectors according to Dragos in Q2 20254. An Illumio report from October 2025 shows 77% of organizations monitor east-west traffic, yet 40% of that traffic lacks sufficient context for confident investigation5. Attackers move laterally without detection nearly half the time. The monitoring exists, but the architecture cannot produce a coherent picture. You face an architecture gap rather than a technology gap.
Regulation compounds the issue
The tightening regulatory environment makes fragmented security architectures dangerous. Frameworks like NIS2 in Europe and CMMC in North America carry strict compliance requirements which bring mandatory reporting obligations and enforcement mechanisms.
If you operate across multiple countries, the compliance burden multiplies. You must apply different regulatory regimes to an estate that cannot report on itself consistently. The teams managing this compliance also keep the network running day to day so they are overextended.
Why point products fail
When facing a new threat, many leaders buy a new security product. They purchase a better firewall or a SASE manufacturing overlay for cloud traffic. These point products solve specific problems but ignore the structural gap.
The main challenge is consistently enforcing the same policies across every site. You must detect threats moving laterally between IT and OT environments and produce audit-ready NIS2 compliance manufacturing evidence without assembling it manually from six different consoles. Focus must shift from product selection to architecture.
Achieving cyber resilience manufacturing at scale
An effective approach means you embed security into the network. SASE, managed detection and response, DDoS mitigation, ZTNA and managed firewall services must operate as a single architecture. You manage this centrally through the GTT Envision platform. GTT Envision is a platform rather than a simple portal. It delivers security governance without adding operational complexity. It adapts to the realities of each site, from a modernized cloud-connected facility to a legacy OT environment with limited change windows, while maintaining centralized policy and compliance oversight.
GTT operates a Tier 1 global backbone with over 400 points of presence across six continents. This means we deliver security services on-net rather than routing them through third-party infrastructure. GTT takes accountability for the full lifecycle. We handle deployment, standardization, monitoring and response across your entire estate. GTT acts as a true partner and a comprehensive service provider.
Rethinking your security architecture
The threat statistics will not improve on their own. Reacting to each new headline with another point product wastes resources and cause team burnout. You need to look honestly at your architecture and ask if it fits the environment it protects.
For most global manufacturers, the answer is no. Assess your current setup and identify where fragmented tools leave gaps in your OT security manufacturing strategy. Read our detailed solution brief, Built-In Cyber Resilience to learn how industry leaders build true cyber resilience manufacturing.
