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 grade is per-buyer rather than a single stamp. A contractor can be in compliance with one buyer and out of compliance with another. The procurement meaning is the same either way: this contractor has been audited by a third party and is cleared to work the site. For buyers, that replaces a manual paperwork chase that used to run 200 times a year per plant. For contractors, it's often the precondition to bid. Buyers don't reroute a project around an ISN gap.
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. A $5M umbrella is a common ask on industrial sites; pipeline and refinery buyers often go higher. Most MSAs also require waiver of subrogation and the buyer named as additional insured.
- OSHA stats. TRIR (Total Recordable Incident Rate), DART rate (Days Away, Restricted, or Transferred), fatalities, and lost-time injuries by year. Buyers set thresholds against Bureau of Labor Statistics medians; below 1.0 TRIR is broadly competitive in low-voltage and security contracting per BLS data on NAICS 238210.
- MSAQ. The Management System Assessment Questionnaire, roughly 200 questions covering written safety programs, hazard communication, fall protection, hot work, electrical safety, confined space, lockout-tagout, PPE policy, and incident reporting. It usually triggers internal work to formalize policies that previously lived in someone's head.
- RAVS. Review and Verification Services. ISN's team reads each safety plan and grades it A through F against the buyer's requirements. This is where many contractors lose ground; a generic OSHA template won't grade well against a refinery operator's expectations.
- 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).
- Drug and background screening. Written policies plus evidence of execution, often a sample of recent records to show the program is operating, not just documented.
- MSAs and indemnity language. Buyer-specific Master Service Agreement plus indemnity, hold-harmless, and waiver of subrogation. Often the longest part of onboarding a new buyer.
The ISN certification process, step by step
Going from zero to ISN-accredited is a multi-month process for a new contractor:
- Subscribe and populate the profile (weeks 1-2). 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 MSAQ (weeks 2-6). Work through the 200-ish questions. Most contractors discover gaps here that require writing or formalizing internal policies.
- Submit safety plans for RAVS (weeks 4-10). ISN's review team grades each plan and sends back redline feedback. Revise and resubmit until grades are acceptable to your target buyers.
- Sign buyer-specific MSAs (weeks 8-12). Each buyer has its own MSA with its own indemnity, insurance, and training requirements. Multiple buyers means multiple rounds.
- Get cleared for site work. Once the profile is graded and the MSA is signed, you appear on the approved-vendor list and can quote work.
- 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 charges contractors an annual subscription that scales with company size and the number of connected buyers. Per ISN's published pricing, the base annual fee starts in the low four figures and rises with revenue band and add-on services like RAVS safety plan reviews. The platform fee is rarely the largest cost. Most contractors spend more on the work it takes to grade well: writing safety plans that survive RAVS review, training records, insurance limits that meet buyer requirements, and staff time to maintain documentation year-round. Plan for the people cost, not just the subscription.
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 audits a contractor's safety program against those OSHA-driven rules plus any buyer-specific requirements. An ISN-accredited contractor is signaling that an independent third party has reviewed its OSHA recordkeeping, written programs, training, and incident history. The two are complementary, and most industrial buyers check both.
ISN vs. Avetta, Veriforce, and ComplyWorks
ISN isn't the only contractor compliance platform. The major alternatives:
- Avetta. Broader industry coverage including retail, hospitality, and facilities. Often used where ISN's industrial focus is overkill.
- Veriforce. Strong in pipeline, midstream, and utility verticals. Operator-driven workforce verification is a focus.
- ComplyWorks. Common in Canadian energy and construction operations. Some US buyers run ComplyWorks alongside ISN.
Documentation requirements overlap heavily across all four platforms: insurance, OSHA stats, written safety plans, training records, drug and background policies. Well-run contractors maintain status on every platform their target buyers use. The marginal cost of joining another platform is far smaller than the cost of losing a buyer.
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 is a real proxy for whether they have a written safety plan, a real OSHA program, and real insurance limits, documented and graded by a third party. 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 moves the pre-qualification work onto a third party: one platform, one standard, one yes-or-no call. See why an ISN-certified security company matters.
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 wants the same paperwork. That's why ISN-accredited integrators get pulled onto industrial bids that non-accredited shops can't even quote. The approved-vendor list is gated on the ISN check, not the camera spec.

How Tec-Tel approaches ISN-grade buyers
Tec-Tel is a nationwide integrator with over 15 years of experience across manufacturing, hospitality, retail, and healthcare. Our standard install package produces what an ISN-driven procurement team expects: insurance certs naming the buyer additional insured, OSHA-aware install practices, written job hazard analyses per site, certificates of training for on-site techs, and a per-site bill of materials with vendor self-certifications attached. Tec-Tel is trusted by industry leaders including Bridgestone, ORBIS, TreeHouse Foods, and Menasha. The common pattern: a procurement lead with an ISN-managed approved-vendor list and an inherited stack from three integrators, looking for one accountable shop.
