Lincoln Electric

Lincoln Electric has been building welding solutions since 1895, and its attack surface reflects that century-plus of industrial sprawl. The company operates 71 manufacturing locations across 21 countries, runs robotic automation systems on shop floors worldwide, and ships proprietary welding alloys globally - each node a potential entry point. The cybersecurity challenge here is rooted in OT/IT convergence: protecting industrial control systems, robotic cells, and connected manufacturing infrastructure alongside traditional enterprise networks. The threat model spans from ransomware targeting production continuity to IP exfiltration around metallurgical R&D and process data. Lincoln Electric's technical domains - welding, metallurgy, manufacturing, robotic automation, and joining technology - generate valuable intellectual property, making it a target for industrial espionage. Security teams working here deal with the reality of securing legacy OT environments that weren't designed for networked access, while also defending modern cloud-connected automation platforms and global supply chain integrations. With over 12,000 employees across a profit-sharing culture dating back to 1934, the organization runs deep on institutional knowledge. Security roles intersect with manufacturing operations, corporate IT, and the company's Welding School - which has trained over 150,000 people since 1917 - meaning security awareness and culture-building aren't theoretical exercises. The company's emphasis on hands-on expertise and continuous improvement signals a technical environment where security practitioners are expected to understand the physical processes they're protecting.
