According to the FBI Internet Crime Report, the agency received more than 4,800 cyber-threat complaints from organizations across critical infrastructure sectors in 2024 alone. As energy management, industrial, and transportation systems become more connected, cybersecurity must evolve alongside them to protect the critical systems we all rely on. To address these challenges, our team: ✔️ Embeds cybersecurity throughout the system lifecycle ✔️ Connects engineering, field execution and long-term maintenance ✔️ Secures industrial control and SCADA environments By aligning cybersecurity, OT, physical security, and communications early, the team helps customers reduce risk and maintain mission readiness. #CybersecurityAwarenessMonth #BuildingIntelligence
