SFTP (Secure File Transfer Protocol) has become a foundational tool for many companies managing daily EDI (Electronic Data Interchange) traffic. It is valued for its simplicity, security, and ease of automation. However, SFTP alone often reaches its limits as EDI complexity, scale, and compliance needs increase. This is where centralizing EDI with a platform like Nexus VAN delivers additional value, giving you the reliability, transparency, and scalability essential for modern supply chains.
SFTP is a secure protocol that enables point-to-point file exchange using SSH for encrypted transfers. EDI teams favor it because of:
Many businesses use SFTP for exchanging standard documents like purchase orders, invoices, and shipment notifications. For organizations with modest volume and relatively few partners, SFTP-based EDI provides reliability without expensive investment.
If your document traffic moves in batches, and partners can tolerate minor delays, SFTP is an efficient means to keep EDI moving. Scenarios include:
In these cases, SFTP delivers what you need with little operational overhead.
Most manufacturers and distributors operate mixed EDI landscapes with partners on AS2, SFTP, and APIs. SFTP frequently becomes the default for small and medium partners that do not require advanced features or tight service level agreements (SLAs).
SFTP is also effective for moving files between internal business units, subsidiaries, or applications under your control—particularly where compliance or real-time tracking is not mandatory.
SFTP secures the data in transit but does not natively provide receipt confirmations or verifiable audit trails. There is no cryptographic proof that a trading partner received and processed a file. This can lead to uncertainty during disputes, audits, or operational incidents.
SFTP file drops offer no direct feedback loop. Without supplementary monitoring, teams may be blind to missed, duplicated, or unprocessed documents. Investigation and troubleshooting become time-consuming, especially at scale.
Each trading partner connection requires manual handling—separate credentials, custom folder permissions, and ongoing SSH key management. Time and resource demands escalate as your network grows.
SFTP does not bridge all protocol gaps. As you onboard partners using AS2, APIs, or older protocols, ensuring seamless and consistent delivery across your network becomes increasingly difficult with SFTP alone.
Value Added Networks (VANs) act as managed hubs for EDI, offering connectivity, translation, visibility, and support across diverse trading partner requirements and technical standards. Moving to a platform like Nexus VAN often makes sense when:
In fact, case studies such as Spanx and TIGI have demonstrated reduced costs, eliminated hidden fees, and improved visibility after switching to Nexus VAN.
List all current trading partners with these columns:
Identify partners with low volume, low risk, and no unique compliance needs. These may remain on SFTP, managed either directly or through a central platform.
Flag those with strict auditing, high transaction value, or mandated use of advanced protocols. These connections are usually best managed through a VAN with built-in auditing and compliance tools.
Evaluate your monthly per-message fees, setup charges, mailbox or migration fees, and labor required for supporting SFTP infrastructure. Compare those expenditures to the predictable kilo-character pricing used by Nexus VAN.

Few organizations can (or should) standardize on a single protocol. SFTP remains essential for straightforward, batch, or internal transfers. However, as complexity, risk, and scale rise, the case for centralizing with a VAN becomes clear. Nexus VAN’s approach allows you to keep using SFTP where it is ideal while adding visibility, accurate billing, and enterprise-grade support on top.
Most teams find that over time, simplifying EDI operations leads to lower costs, fewer support headaches, and better outcomes for finance, IT, and the business as a whole.
The need for reliable tracking, compliance, multi-protocol support, and cost transparency usually drives the switch. As EDI partner networks grow, the limits of SFTP in auditing, message management, and scaling become apparent. A VAN like Nexus VAN consolidates these requirements in a unified platform.
No. Nexus VAN enables a hybrid approach. You can maintain direct SFTP connections for low-risk, batch, or internal partners, while centralizing higher-value or complex connections through the VAN. This balances control with simplicity and oversight.
Nexus VAN uses transparent, tiered pricing based on actual kilo-characters transmitted. There are no per-message, mailbox, setup, migration, or compliance fees. You are billed precisely for the data you send and receive, rather than inflated transaction counts.
Migrations are structured to minimize risk. A dedicated migration dashboard gives full visibility, all migration services are included, and a 90-day free trial lets you validate performance before making a financial commitment. Both low-risk and high-complexity flows can be transitioned gradually for stability.
Yes. The platform connects with every major VAN worldwide and supports all significant protocols, including SFTP, AS2, APIs, and multiple document standards like X12, EDIFACT, HL7, and more. This ensures connectivity regardless of your partner’s system.
SFTP remains a solid choice in many EDI workflows, particularly in simple or low-risk settings. However, as your organization’s requirements evolve, Nexus VAN provides the operational confidence, billing transparency, and future-proofed infrastructure you need to keep EDI simple, predictable, and scalable. Backed by industry experts and real customer success stories, the platform is designed to help you move forward—without risking business continuity or overspending on your EDI.
