How Lesaffre Boosted Operational Efficiency with Secure Remote Connectivity

How does a global manufacturer ensure secure, reliable remote access to hundreds of machines installed by different suppliers? Lesaffre found the answer with Ewon Cosy+ and Talk2m Pro. Explore how they streamlined maintenance, boosted uptime, and unified remote access worldwide.

The Challenge

Lesaffre’s production environment relies on machines installed and maintained by numerous external suppliers. This created several key challenges:
• Lack of standardized remote access across different machines and vendors
• Need for secure connections aligned with strict IT and OT cybersecurity requirements
• Limited visibility and control over who accesses industrial equipment
• Growing need for fast, reliable remote maintenance to avoid production downtime

Without a unified approach, remote interventions were complex, time-consuming, and potentially risky from a cybersecurity perspective.

The Solution

To address these challenges, Lesaffre deployed Ewon Cosy+ combined with Talk2m Pro, creating a secure and centralized remote access infrastructure across its sites.


Key elements of the solution included:

Easy-to-deploy remote access gateways
Ewon Cosy+ devices were quickly installed on machines, connecting OT networks to IT systems through secure outbound VPN connections — fully aligned with firewall policies. 

Centralized access management with Talk2m Pro
All remote connections are managed through a single platform, allowing Lesaffre full control and visibility over access to every machine. 

Strict access control and cybersecurity compliance
External suppliers can only access machines upon request, with permissions granted for a limited time—ensuring full control and traceability. 

Standardization across suppliers
Lesaffre made the integration of Ewon solutions a requirement for all partners, ensuring a consistent and secure approach across all equipment. 

Scalable integration of new and legacy machines
New machines are automatically integrated into the system, while legacy equipment is progressively connected to the Talk2m environment.

The Result

In less than a year, Ewon Cosy+ has already delivered clear and measurable benefits across operations, security, and scalability:

 Operational Efficiency

• Faster troubleshooting thanks to reliable remote access
• Reduced downtime and maintenance costs
• Standardized access across all suppliers

 Security & Control

• Full control over who connects, when, and for how long
• Outgoing‑only VPN fully aligned with OT security policies
• Centralized management through Talk2m Pro

 Scalability

• All new machines are now automatically integrated
• Legacy equipment is being progressively added
• Long‑term goal: unify all machines under one Talk2m Pro account

“Our subcontractors can easily connect to our machines, but we retain absolute control over who accesses our machines. We really exploit the full functionality of Talk2m pro."
