Modern factories are adopting advanced technologies such as robotics (physical AI), Industrial IoT (IIoT) sensors, digital twins, and virtual PLCs to reimagine production processes, reduce downtime, and improve productivity. As IT, OT, and IoT environments converge, manufacturers increasingly require security architectures that can protect highly distributed, hybrid, and legacy environments—while avoiding the complexity of fragmented tools.
Secure Access Service Edge (SASE) has emerged as a powerful solution that brings together networking and security functions into a cloud‑delivered platform. Beyond improving user experience and cost efficiency, SASE strengthens security posture at a time when manufacturing faces an expanding attack surface, growing exposure to supply-chain risk, and increasing dependence on cloud‑based systems. Indeed, manufacturing has been the most targeted sector for the last four years, as per IBM’s X-Force 2025 Threat Intelligence Index. Increasing frequency apart, the median cost of a manufacturing ransomware attack is now estimated at $600,000.
Here are 5 Ways SASE is Reducing Cyberthreats in Manufacturing and OT Environments
1. Make Zero Trust as default: Zero Trust has become foundational for securing converged IT–OT ecosystems. It operates on three pillars: explicit identity verification, least-privilege access, and an “assume breach” mindset. SASE enhances this by integrating with existing identity systems and continuously validating users, devices, machines, and applications. Access is granted strictly to the intended system rather than the broader network, reducing lateral exposure and ensuring only verified, compliant entities interact across environments.
2. Prevents lateral movement by micro-segmentation: Many factories still operate flat networks, allowing a compromise in IT to spread quickly into OT environments. SASE‑enabled secure SD‑WAN, combined with next‑generation firewall capabilities, enables true micro‑segmentation across production zones. This ensures that even if malware enters one asset or line of production, its movement is contained. By designing with an “assume breach” principle, manufacturers can significantly reduce the operational impact of ransomware or targeted intrusions.
3. Application (incl. OT) aware traffic control: Historically, OT networks lacked deep visibility, making it difficult to detect protocol misuse or unauthorized commands. SASE platforms now extend application awareness to OT protocols, providing real-time traffic monitoring, anomaly detection, and command-level inspection across ICS and SCADA systems. This unified visibility—via a single-pane-of-glass—helps security and operational teams respond quickly to threats while ensuring production continuity.
4. Strengthening Supply Chain and Ecosystem Access: Manufacturers depend heavily on a global supply chain involving vendors, contractors, partners, and software providers. Conventional VPN access is increasingly risky because it often grants broad network reach. SASE applies Zero Trust Network Access (ZTNA) principles to ecosystem users by validating identity, assessing device posture, and providing strictly application-specific access. Modern browser-based access models further reduce exposure by isolating users from internal networks. This significantly mitigates the risk of supply chain–origin intrusions, which have become a common attack vector.
5. Protecting Data Across Cloud and SaaS Applications: As cloud and SaaS platforms—including mission-critical ERP systems—become more prevalent, data now flows far beyond physical premises. SASE combines ZTNA, data loss prevention (DLP), and secure SaaS controls to enforce identity-led data protection wherever users operate. This ensures that sensitive manufacturing data is accessed only by authorized users on trusted devices, enabling consistent, organization-wide visibility and compliance as cloud adoption grows.
The Broader Role of SASE Beyond Security
More than ever before, manufacturing environments require SASE to deliver secure, high-performance connectivity across global locations. Manufacturers adopting SASE-driven architectures have been able to replace legacy networks, improving global connectivity, remote access, and cloud integration. SASE‑driven architecture delivers better performance through:
- Modernise global connectivity: By replacing fragmented, hardware-heavy networks with a cloud-first fabric, manufacturers can achieve resilient, predictable performance and real‑time visibility across factories, logistics hubs, and offices worldwide.
- Support hybrid and remote operations: As workforces move fluidly between plant floors, offices, and remote locations, SASE provides secure, identity‑driven access to critical applications and OT systems — without relying on outdated VPN models.
- Accelerate cloud adoption for production workloads: As ERP, MES, digital twins, and other production applications migrate to the cloud, SASE ensures consistent policy enforcement and optimised performance, regardless of where workloads reside.
Beyond the security and performance benefits, SASE also simplifies IT operations by facilitating 20% faster time to market, 10-15% improved network availability and 25% better service quality, in turn leading to lower costs and enhanced operational efficiencies. As networking and security systems are consolidated, it simplifies IT and lowers expenses and operational overheads by facilitating centralised control via uniform policies.
