Sigil is a proof tool showcased by sealedby.com for freight logistics scenarios, positioning itself around “sealed proof of delivery.” Based on the crawled text, it serves carriers and brokers, with its core value being more trustworthy delivery evidence for each load: sealed bills of lading, GPS-chained proof of delivery, and tamper-evident audit records. The website also emphasizes that any load can be verified on sealedby.com.
In terms of feature modules, the public information clearly mentions three items: Sealed bill of lading, GPS-chained proof of delivery, and tamper-evident audit records. It looks more like a vertical SaaS product built around bills of lading, delivery confirmation, and audit trails, rather than a general-purpose transportation management system. The term “GPS-chained” suggests that delivery proof may be linked to location information to strengthen the chain of evidence; “tamper-evident” highlights that attempts to alter records can be detected. However, the available text does not explain the actual workflow, or whether there are mobile apps, driver-side tools, dispatcher tools, or an admin dashboard.
The crawled content does not disclose plans, pricing, a free tier, or trial information, so its value-for-money model cannot be assessed. On third-party integrations, there is also no mention of support for TMS, ERP, accounting systems, e-signature tools, maps, or fleet management platforms. There is no public information about team collaboration and permissions, APIs, or developer support. For data security and compliance, the only confirmed point is its emphasis on tamper-evident audit records; no compliance details such as SOC 2, ISO 27001, GDPR, or data retention policies were found.
Its main advantage is a very clear positioning: it directly addresses freight-industry pain points such as whether a delivery really happened, whether the supporting documents can be trusted, and whether the process can be audited afterward. If the actual product can reliably generate verifiable records, it could be valuable for carriers and brokers in dispute resolution, customer reconciliation, and defending against claims. The downside is that publicly available information is too limited, with missing details on pricing, deployment, integrations, permissions, security, and support. Enterprise buyers would need to conduct further due diligence before procurement.
The accessibility of sealedby.com from mainland China cannot be determined from the text, so it is marked as unknown. Network connectivity, payment methods, contracting entity, and local compliance are also not disclosed. If Chinese freight companies need similar capabilities, they should also evaluate local TMS, e-signature, electronic waybill/POD, location tracking, and audit-trail solutions, with particular attention to compatibility with domestic maps, electronic signatures, and data compliance requirements.
