Crimson7 Specialty Services is a consulting offering focused on security assessments for hardware, firmware, industrial control systems, and physical security environments where digital and physical threats converge. The service includes hardware security assessment covering debug interfaces, bus sniffing, chip-level analysis, side-channel assessment, and hardware implant detection. It also covers firmware and IoT security work, including firmware extraction and analysis, protocol reverse engineering, and vulnerability research for embedded and connected devices. For industrial environments, Crimson7 performs security assessments of SCADA systems, PLCs, HMIs, and industrial protocols, designed to avoid disrupting production. Physical security services include physical penetration testing, access control assessment, social engineering, badge cloning, lock bypass testing, surveillance system evaluation, and covert entry exercises. The practice operates a dedicated hardware lab equipped with oscilloscopes, logic analyzers, JTAG tools, and software-defined radios for wireless protocol testing (Wi-Fi, Bluetooth, Zigbee, LoRaWAN, cellular). Findings from specialty assessments are integrated with the company's offensive and defensive engineering services, informing detection rules and red team scenarios. Assessments are aligned with standards including IEC 62443, NERC CIP, NIST Cybersecurity Framework, ISO 27001, and FDA cybersecurity guidance. The service also covers cloud infrastructure security assessments for AWS, Azure, and GCP, including configuration review and identity management assessment. Industries served include energy, manufacturing, healthcare, transportation, and financial services.</description> <parameter name="summary">Consulting service for hardware, firmware, ICS/OT, and physical security assessments
