Yes, a Faraday cage (commonly demonstrated protecting people inside from Tesla coil sparks, so likely what you mean by "Tesla cage") blocks external electromagnetic fields via conductive enclosures. If the attacks involve pulsed RF/microwaves—as some Havana Syndrome investigations and whistleblower reports have suggested—properly designed shielding integrated into infrastructure (metal mesh, conductive layers, sealed rooms like SCIFs) would protect against them by preventing the energy from penetrating. It requires full, gap-free construction and works best for fixed high-value sites. Effectiveness varies with frequency, power, and angle. Non-EM causes wouldn't be blocked. Technically viable where needed.
