Gurvinder S. Kahlon is the Vice President & General Manager of Stratasys Direct. With a wealth of experience in Digital Manufacturing, Semiconductor Technologies, Software Development, and Factory Automation spanning over 20 years, Gurvinder brings a unique blend of strategic insight and hands-on expertise to the table. He holds an MBA from the Carlson School of Management at the University of Minnesota and a Bachelor of Mechanical Engineering degree from the University of Mumbai.

In February 2024, German battery manufacturer VARTA was hit by a cyberattack that crippled operations across five production plants. The incident forced shutdowns and delayed critical deliveries, sending shockwaves through the European supply chain. It wasn’t just a tech problem—it was a manufacturing crisis. Welcome to the reality of smart factory cyber risk.

In another high-profile case, Brunswick Corporation faced a cyberattack in June 2023 that not only disrupted operations for nine days but also exposed sensitive employee and customer data, including Social Security numbers and financial records. These breaches highlight the dual risk in manufacturing: operational shutdown and compromised trust.

And the financial stakes are staggering. In May 2024, UnitedHealth CEO Andrew Witty confirmed the company paid a $22 million ransom following a devastating cyberattack on its Change Healthcare unit. The breach disrupted pharmacies and billing systems nationwide, showing how a single attack can trigger widespread fallout—and costly decisions.

🤖Why Cybersecurity Is Crucial in Modern Manufacturing

Since COVID-19, manufacturers have rapidly accelerated their digital transformation efforts to stay competitive. From adopting cloud-based ERP systems and connected machinery to enabling remote diagnostics and predictive maintenance, factories are becoming highly interconnected digital ecosystems.

This transformation, while essential for global competitiveness, has dramatically expanded the attack surface. Legacy systems are now interfacing with cloud infrastructure, OT (operational technology) networks are connecting to IT systems, and data is flowing across suppliers and partners around the world. Every endpoint, sensor, or digital workflow becomes a potential vulnerability if not secured.

In this new paradigm, cybersecurity is not just about protecting data—it's about ensuring business continuity, protecting intellectual property, and maintaining customer trust. With 3D printing now producing flight-critical parts and medical devices, the stakes are higher than ever.

🔒 Stratasys Direct: A Case Study in Industrial Cybersecurity

With over 25 years of U.S.-based manufacturing experience, Stratasys Direct has served critical sectors like aerospace, defense, and medical. This deep-rooted experience has shaped a culture where security, compliance, and quality are not afterthoughts but part of the core operating DNA. The company’s track record of delivering highly regulated, mission-critical parts has driven continual optimization of its cybersecurity infrastructure and workflows.
Stratasys Direct has become a blueprint for how to do it right. Their approach:

Defense-Grade Compliance

  • CMMC 2.0 Level 2 certified
  • NIST SP 800-171, ITAR, DFARS 252.204-7012 compliance
  • Protects both Controlled Unclassified Information (CUI) and Federal Contract Information (FCI)

Secure Workflows & Platforms

  • CAD files are sliced locally; no cloud-based slicing
  • Files are deleted post-print to protect IP
  • Print management via GrabCAD with role-based access, multi-factor authentication (MFA), and full audit logs

Hardware & Physical Security

  • Encrypted firmware and tamper-proof boot protocols
  • Badge-only facility access + federal background checks
  • Isolated U.S.-based production zones for ITAR-sensitive work

✅ 6 Actionable Strategies for Cyber-Resilient 3D Manufacturing

  1. Adopt a Compliance Framework Implement standards like CMMC or NIST SP 800-171 to build a secure foundation.
  2. Use Secure Slicing and File Handling Avoid cloud-slicing where possible. Always encrypt and delete files after use.
  3. Invest in Hardware with Built-in Protections Choose printers with secure boot, signed firmware, and internal auditing.
  4. Enforce Physical Access Controls Treat your production floor like a data center. Limit access, badge in/out, and vet visitors.
  5. Vet Your Supply Chain Ensure suppliers and partners follow equivalent cybersecurity practices.
  6. Partner with Proven Providers Work with vendors like Stratasys Direct who can meet defense, aerospace, and medical security requirements.

âš¡ Evaluate Your Cybersecurity Maturity

Cyberattacks aren't just a threat—they're a certainty. The question is whether your organization is ready.

  • Are your CAD files secure at every step?
  • Can you demonstrate compliance to regulators or customers?
  • Are your suppliers part of your cybersecurity plan?
