Customer audit prep moved from 12 weeks to a live dashboard.
Electronics ESD plant, Sriperumbudur · Chennai-Sriperumbudur
A 950-worker electronics EMS plant in Sriperumbudur serving a global OEM anchor customer faced quarterly customer audits with the bar rising every cycle. The customer's quality team had started asking for per-zone access pulls for the ESD-controlled cleanroom, contractor induction certificates per shift, and inbound logistics traceability per delivery. Post-Zentry Sitewide + Induct, the customer audit closes in 2 hours from a live dashboard.

What the plant was facing.
The plant's anchor customer is a global OEM with non-negotiable audit standards. Every quarter the customer's quality team conducted a plant audit. The bar rose every cycle. The previous audit closed with three findings: incomplete per-zone access logs for the ESD-controlled cleanroom, missing contractor induction certificates for two agency workers, and inbound logistics traceability gaps for three deliveries. The customer warned that the next audit would be the decision audit on the renewed supply contract.
The plant's pre-Zentry stack was the Hikvision biometric, a paper visitor register, a separate inbound vehicle log, and a paper induction sign-off. The customer audit prep cycle had grown to 12 weeks. The Plant Head had pulled the Quality and Security teams from line-side work to support the audit prep. The line ran short-handed for three months of every year just to satisfy customer audit cycles.
How Zentry was deployed.
Zentry Sitewide + Induct deployed on Cloud tier. The customer's India-resident data clause was satisfied by the multi-AZ India deployment. The existing Hikvision biometric and ANPR hardware stayed in place. Induct kiosks were installed at every cleanroom entry, configured with the plant's specific ESD induction and cleanroom protocol modules. Gate Access view replaced the legacy access control narrative.

ESD induction certificate validated at the cleanroom entry. Access blocked if certificate expired or missing. Customer auditor verifies any cleanroom entry back to the originating induction session.
Customer auditor and OEM quality engineer check-in via kiosk. DPDPA-compliant, NDA captured at entry.
CLRA Forms XIII to XXIII auto-generated. Per-agency, per-period.
Inbound logistics traceability for every delivery. Per-delivery audit trail for the customer's supply chain audit.
The metrics that moved.
What happened at the next audit.
The decision audit post-Zentry closed in 2 hours with zero findings. The customer's quality team specifically called out the ESD cleanroom access chain and the inbound logistics traceability as model practices. The supply contract was renewed for a 3-year term with expanded scope (additional product lines). The plant's revenue from this customer increased 40% year-over-year.
"Our anchor customer was about to walk. Three findings on the previous audit, the next one was the decision audit. We had 12 weeks. Zentry Sitewide plus Induct went live in 7 weeks. The customer audit closed in 2 hours with zero findings. The customer renewed the contract and expanded the scope. Without Zentry we would not have kept the customer."All case studies →

Common questions on this deployment.
Why was Sitewide + Induct chosen instead of full Sitewide+?
The plant did not need Learn (training was already handled by the customer's mandated LMS) or Worksheet (project P&L was already in the customer's portal). Sitewide gave the gate stack, Induct gave the ESD cleanroom induction chain. 5 modules covered the audit gap exactly. Sitewide+ would have been an over-buy at this stage.
How does the platform handle the global OEM customer's India-resident data clause?
Cloud tier on India-resident, multi-AZ infrastructure satisfies the clause. The customer's IT security team independently verified the data residency posture during deployment. The verification became part of the platform's customer-audit-ready evidence.
Is this a real customer or a composite?
Composite story drawn from real Zentry deployments at EMS plants in the Chennai-Sriperumbudur electronics cluster. Industry, geography and metrics are representative. Named references are available under NDA during qualification, including the OEM customer reference where permitted.
How does the platform handle ESD cleanroom-specific induction at entry?
Induct kiosk runs the ESD-specific induction module. The worker takes the on-screen exam on ESD protocols, ESD-grade clothing, ESD-safe handling. Pass, get certificate. At the cleanroom entry gate, the certificate is validated. Access blocked if expired or missing.
How long did the deployment take given the customer-audit urgency?
7 weeks from contract signature to go-live. The customer's audit decision date was the forcing function. Cloud tier was chosen for fastest deployment. The Implementation team ran a compressed schedule with parallel hardware integration and software configuration tracks.
Did the customer audit pass on the first attempt post-Zentry?
Yes. The customer's quality team's pre-audit walkthrough flagged zero issues. The actual audit closed in 2 hours with zero findings. The customer specifically praised the ESD cleanroom access chain and the inbound logistics traceability.
Has the plant added other Zentry modules since?
The plant is evaluating Worksheet now that the customer's portal is being deprecated. The plant wants its own project P&L visibility. The Worksheet upgrade is a configuration change, no re-deployment.
Can other electronics plants reference this deployment?
Yes. Named references under NDA are available during qualification. The reference plant has hosted multiple prospect calls with both the prospect's Plant Head and their anchor customer's quality team.
One event. Six audit narratives.
Every gate read, every kiosk submission, every certificate validation lands in a single tamper-evident, signed log. From that one event, six modules produce six distinct evidence trails, for six different audits, six different inspectors and six different heads inside the plant.
