Sine vs TrustLayer

Sine provides visitor, contractor, staff, and compliance management for facilities. Sine Core supports customized check-in flows, electronic entry documents, and branded kiosks. Contractor tools cover onboarding, inductions, permits, certifications, and compliance records, while the activity dashboard shows expected arrivals, people on site, and searchable check-in history. The Sine Pro mobile app adds nearby-site check-in with geofencing, QR codes, visitor notifications, and mobile badge printing. Listed integrations include Microsoft Teams, Slack, Outlook, Entra ID, Eventbrite, Gallagher, Honeywell EBI, Cm3, and webhooks. Plans are based on estimated check-in volume, include unlimited hosts, and apply a fair usage policy if use exceeds the plan level. Small through Large plans start with a 30-day free trial; Sine contacts customers with billing information after it ends. The paid service has no free plan, though the Sine Pro mobile app is listed at free. Sine says it uses AWS infrastructure, encrypts data in transit, conducts regular audits and penetration tests, and complies with GDPR requirements.

TrustLayer is a web and API platform for automating vendor compliance documents and insurance verification. It requests, collects and follows up on certificates of insurance, W9s, licenses, driver licenses, contracts and custom documents, while sending reminders about expirations. Compliance Assistant and Compliance Analytics provide visibility into risk. Pulse supplies policy-level proof of insurance, and TrustLayer Plus offers outsourced risk management. Vendors can work without signing in; brokers and project managers receive dedicated access paths. Procore and QuickBooks integrations synchronize compliance information for construction and accounting workflows. The Platform API connects applications to compliance profiles, parties, projects and documents through JSON. API v2 is recommended, while v1 is deprecated and scheduled for sunset on March 31, 2027. The free Starter plan covers up to 50 vendors; additional vendors cost $10 per vendor per month. TrustLayer states it completed a SOC 2 Type II audit.
