ISN earns its reputation for the scale of its network, its RAVS third-party verification, and its cross-industry benchmarking and analytics. Where FacilityOS pulls ahead is the operational layer: contractor compliance that's enforced at site entry rather than verified in a central network, native integration with visitor management and emergency mustering, turnkey kiosk hardware, and a faster path to go-live. If the question is "is this contractor prequalified and verified across our network?", ISN answers it well. If the question is "can a non-compliant contractor get onto our floor right now?", only FacilityOS answers it by design.

The most useful question is who owns the problem. If contractor compliance is primarily a procurement-and-safety prequalification program — and you need third-party document verification, a large pre-vetted contractor pool, and cross-industry benchmarking — ISNetworld is a credible network. If contractor compliance is an operational and security problem owned by site managers, facility teams, and security leads — where verification has to happen at the gate, contractors must be accounted for in emergencies, and compliance spans ITAR, GMP, FSMA, and CTPAT as well as OSHA — FacilityOS is the more defensible long-term decision.

No — and that's an honest scope difference. RAVS human verification, a multi-client supplier network, and sourcing tools like ISN SmartSource are core to what ISN does, and if third-party verification and discovering new contractors across an industry network are your primary requirements, ISN is built for that. FacilityOS focuses on verifying contractors before entry, enforcing requirements at the door, and accounting for everyone on-site — use cases a prequalification network isn't built to cover.

No. FacilityOS is a client-funded platform — your contractors aren't charged a network fee to be compliant with you. ISNetworld operates a subscription network in which contractors and suppliers typically pay recurring fees, often scaled to workforce size, to qualify and maintain their standing with each hiring client — a cost that compounds for contractors working across multiple operators.

In most cases, yes — conceptually, and this is a common situation since many hiring clients mandate ISN. ISNetworld can remain your system of record for prequalifying and verifying contractors, while FacilityOS becomes the enforcement layer at your sites: VisitorOS verifies compliance at check-in, flags or denies anyone whose standing has lapsed, and feeds on-site presence into EmergencyOS for real-time mustering. Note that ISNetworld is not currently a published FacilityOS integration partner, so any direct data sync would need to be scoped with both vendors. Even without a native connection, FacilityOS enforces your requirements at the door regardless of where the underlying records live — and for teams not committed to ISN, ContractorOS delivers verification and enforcement natively.

With ISNetworld, prequalification and verification records live in the contractor network — there is no integrated, real-time accountability for who is physically on-site. With FacilityOS, contractor check-in data feeds directly into EmergencyOS, enabling digital roll calls, two-way communication, building sweeps, and automated drill reporting. For audited facilities, that integration is the difference between having records and having accountability.

Yes — and this is one of FacilityOS's structural advantages. Start with ContractorOS, then add VisitorOS for check-in, EmergencyOS for evacuation and drill readiness, LogisticsOS for mailroom and asset management, or SecurityOS for physical identity and access control — all within the same platform, without switching vendors or migrating data. ISNetworld expansion deepens your prequalification network; FacilityOS expansion deepens your control over the facility itself.
