Start with the question you have
Start with the question you have: common client questions and the PNH service that answers each one Ten client questions mapped to the service that answers them. YOUR QUESTION PNH SERVICE Which threats matter at our site, and how much? 01 Threat, vulnerability and risk Can a vehicle reach the building, and how fast? 02 Hostile vehicle mitigation Will the structure and windows resist a blast? 03 Blast-resistant engineering What if fragments, debris or a drone strike it? 04 Blast, fragment and impact How do we shield critical equipment from drones? 05 Passive anti-UAV protection How much explosive can we store, and where? 06 Explosives safety and siting Can an equipment failure stay inside one room? 07 Containment and enclosures Does our facility meet antiterrorism criteria? 08 Antiterrorism and force protection How do we protect a site that cannot go down? 09 Data centers and critical facilities A barrier or structure failed. Why? 10 Forensic and expert witness Our tender has a blast or impact specification. Pre-bid and tender support Most sites raise more than one question. One engineer leads every service, so the answers fit together.
