CoreTech is a UK-based security firm with deep expertise in vulnerability research, reverse engineering, and offensive capabilities across embedded and networked systems. The tech stack—C, C++, ARM, x86, Ghidra, IDA Pro, Wireshark, UART, JTAG—signals focus on low-level systems analysis and hardware security rather than application-layer defenses. Active projects around new offensive services and long-term capability development, coupled with hiring that skews heavily toward senior and lead roles, suggest a mission-critical organization scaling specialized technical depth over headcount.
