What is ISN?
ISN stands for ISNetworld, a contractor compliance management platform run by ISN Software Corporation, headquartered in Dallas, Texas. It launched in 2001 serving oil and gas operators and has since expanded into utilities, manufacturing, mining, chemicals, and food and beverage. ISN isn't a government agency or a certification body in the OSHA, BICSI, or NICET sense. It's a private platform that owners of high-risk facilities subscribe to so they can manage contractor paperwork at scale. The buyer defines its thresholds (insurance limits, OSHA TRIR caps, training, drug testing, MSA terms) and vets every contractor against them; the contractor pays an annual fee, submits documentation, gets a graded profile, and becomes visible to every ISN-subscribing buyer. For the short definition, see our glossary entry on ISN.
"ISN certification" is the working shorthand. ISN's own term is "accredited" or "in compliance," and the result is buyer-specific rather than a single universal stamp. A contractor can meet one buyer's requirements and not another's because requirements vary by account, location, and work scope. ISN gives the buyer a structured record to review, but the hiring client retains responsibility for the final qualification decision.
ISN certification requirements
Thresholds vary by buyer, but the core documentation set is consistent across nearly every ISN-driven program:
- Insurance. Certificates of insurance for general liability, auto, workers compensation, umbrella, and any specialty coverage the buyer requires. ISN may compare policy limits, insured parties, deductibles, dates, carrier information, and requested endorsements with the hiring client's requirements.
- OSHA stats. TRIR (Total Recordable Incident Rate), DART rate (Days Away, Restricted, or Transferred), fatalities, and lost-time injuries by year. ISN may compare reported data with OSHA recordkeeping documents and the requirements configured for the hiring-client account.
- Company questionnaires. Company information and records requested through the contractor account. The exact questions depend on the hiring client and work scope.
- RAVS. Review and Verification Services. ISN's team compares submitted written programs and supporting documents with regulatory and hiring-client requirements and may provide review feedback.
- Training records. Evidence of OSHA 10, OSHA 30, first aid, CPR, and any site-specific training the buyer requires (TWIC for ports, NFPA 70E for high-voltage zones, orientation videos).
- Other buyer requirements. These can include drug and background screening policies, workforce records, permits, and other site-specific documentation.
- MSAs and indemnity language. Buyer-specific Master Service Agreement and any insurance, indemnity, training, or site-access terms selected by the buyer.
The ISN certification process, step by step
The sequence varies by buyer, but contractors generally work through these stages:
- Subscribe and populate the profile. Pay the annual fee, create the company profile, connect to the required buyers, and upload existing insurance certs, OSHA logs, and training records.
- Complete the requested company information. Work through the questionnaires and records selected for the account and connected hiring clients.
- Submit selected documents for RAVS review. ISN may compare insurance, health and safety records, written programs, training records, and supporting documents with the applicable requirements. Address review feedback where needed.
- Complete buyer-specific requirements. Each buyer has its own MSA with its own indemnity, insurance, and training requirements.
- Obtain the hiring client's decision. The buyer determines whether the contractor meets its requirements for the applicable work and location.
- Maintain annually. Insurance renewals, updated OSHA stats, re-attestation to MSAQ items, RAVS deltas. Mature contractors treat this as a continuous program.
How much does ISN certification cost?
ISN states that contractors pay an annual subscription fee and a one-time account setup fee per country. Contractor pricing is based on the company's three-year average workforce and the countries in which it operates. ISN describes the subscription as all-inclusive, regardless of the number of connected hiring clients or tools used. Fees can change, so use ISNetworld's current contractor pricing page for the actual amount. Contractors should also plan for the internal work required to collect, review, correct, and maintain the records their hiring clients request.
ISN compliance vs. OSHA compliance
OSHA, the Occupational Safety and Health Administration, is the federal agency that writes workplace safety regulations (29 CFR 1910 for general industry, 29 CFR 1926 for construction) and enforces them through inspection, citation, and penalty. It does not issue contractor certifications. ISN is a private platform that can compare contractor-submitted records with regulatory and hiring-client requirements. The review does not replace the contractor's compliance obligations or the hiring client's final qualification decision.
ISN vs. Avetta, Veriforce, and ComplyWorks
ISN isn't the only contractor compliance platform. The correct platform is the one each hiring client requires:
- Avetta. A contractor prequalification and supply chain risk-management platform used by its own hiring-client network.
- Veriforce. A contractor and workforce qualification platform used by its own hiring-client network.
- ComplyWorks. Another contractor-management platform that may be required by specific buyers or regions.
Documentation requirements overlap heavily across all four platforms: insurance, OSHA stats, written safety plans, training records, drug and background policies. Confirm the required platform and account connection with procurement before starting a submission.
What ISN means for buyers and integrators
If you're a procurement or EHS lead at a manufacturer, utility, refinery, or chemical plant, ISN certification of your security integrator gives you a structured record of submitted safety, insurance, training, and regulatory information. ISN states that its reviews are informational and do not replace the hiring client's due diligence. A camera install on an active manufacturing floor isn't the same risk profile as a corporate office. Forklifts, lockout-tagout zones, confined spaces, and overhead hazards are real. If a tech gets hurt, you face OSHA reporting, workers' comp claims, and possible production downtime. ISN structures part of the prequalification record while the buyer retains the approval decision. See what ISN certification means for industrial security buyers.
On the integrator side, most security buyers don't think of camera installs as high-risk work; industrial buyers do. A camera tech on a refinery climbs the same ladders as a welding contractor, and the plant manager may require the same qualification records. Some buyers require an active ISNetworld connection before a contractor can work or bid; others use a different review process. For the detailed integrator guide, see ISN certification for security integrators.
How Tec-Tel approaches ISN-managed sites
Tec-Tel scopes industrial security work around the records each customer and site requires. That can include insurance documentation, crew and training records, site safety planning, and a per-site bill of materials. The common pattern is a procurement lead with an ISN-managed approved-vendor list and an inherited stack from three integrators, looking for one accountable shop.
