🚨 Manufacturing Faces Escalating Cyber Risks

💡 Cyberattacks on manufacturing are increasing in frequency and severity, targeting production, supply chains, and IP.

⚠️ Downtime, regulatory penalties, and reputational damage make these breaches more than just financial losses.

🔍 Human factors remain the weakest link – social engineering and insider threats bypass traditional security measures.

🔥 Proactive, human-focused solutions are critical to detect vulnerabilities before attackers exploit them.

👥 AUMINT Trident simulates real-world social engineering attacks, providing actionable insights and ongoing training to strengthen your human firewall.
