Origin
Built by people who defend networks every day.
ECHO NERO is a spin-out venture of JK Computer Solutions, a managed IT and cybersecurity provider established in 1993. It was conceived inside a security practice that protects businesses, healthcare providers, defense contractors and public agencies, and it is being developed with the backing of JK's parent company, Essex Main Stuart LLC.
Security is layered. Glass was the missing layer.
Our clients already rely on us for endpoint detection and response, email security, identity protection, backup and monitoring. Every one of those layers protects data on a network. None of them stops a conversation from being read off a window. ECHO NERO extends the same defense-in-depth thinking from the network to the physical room.
Operational security discipline
We apply the same rigor we use for client security programs: threat modeling, layered controls, documentation and validation.
Regulated-sector experience
Our practice supports HIPAA-regulated healthcare and CMMC-bound defense contractors, where confidentiality is a compliance requirement, not a preference.
Real-world deployment
We deploy, monitor and support security tooling in live environments across Illinois, Tennessee, Massachusetts and France.
Forensics and counterterrorism foundation
Our founder's training in cyber forensics and counterterrorism shapes how we think about adversaries: how they gather intelligence, what they target and how to deny them what they came for.
