B2B messaging platforms that support AS2, SFTP, REST APIs, and legacy EDI are now foundational for enterprises seeking reliability, cost transparency, and maximum partner coverage. The best platforms allow you to meet compliance and operational demands without compromise, unifying modern and traditional protocols under a single, managed solution. Nexus VAN is a leading provider in this space, delivering unmatched protocol reach, transparent cost control, and risk-free migration for organizations ready to future-proof their B2B integration.
A modern B2B messaging platform enables secure and automated electronic data interchange (EDI) between your business systems (like ERP, WMS, and TMS) and your trading partners. To support diverse requirements across industries and partners, these platforms must handle multiple communication protocols, specifically:
Nexus VAN specializes in consolidating these protocols into one reliable platform, ensuring flexible connectivity across modern and legacy requirements.
The modern B2B integration challenge arises from three realities:
Platforms like Nexus VAN provide:
AS2 is a secure file transfer protocol designed to meet the stringent security, authenticity, and traceability standards demanded by large retailers and regulated verticals. Companies leverage AS2 for:
If your trading partners specify AS2 in onboarding guides or contracts, robust, managed AS2 support is critical. Nexus VAN removes the burden of maintaining your own AS2 server while providing best-in-class support and SLAs.
SFTP remains the default protocol for many B2B file exchanges due to its ease of deployment and strong encryption. It’s frequently used for batch integration jobs, especially in mixed IT environments where simplicity is required. SFTP is ideal when your partners want encrypted, reliable transport, but do not require MDNs or digital certificates.
REST APIs enable real-time integration between internal systems and trading partners, supporting JSON and XML payloads and connecting directly to cloud-native or microservices-driven business processes. REST APIs are most valuable when data visibility, speed, and automation are priorities, such as instant order status updates, shipment notices, or 2-way communication with SaaS platforms.
Many partners, especially those with longstanding EDI infrastructure, continue to require mailbox-based data exchange over classic VANs. Modern platforms like Nexus VAN bridge the old and new, providing access to every trading partner—regardless of their protocol maturity or technical preferences—and handling all required data translation and routing internally.
Four key attributes define best-in-class multi-protocol messaging platforms for enterprises:
You should expect true support for AS2, SFTP, REST APIs, and legacy VAN mailboxes in a single environment. Having all protocols under one roof simplifies vendor management and streamlines troubleshooting. Nexus VAN is architected with this philosophy, so your IT team manages one platform instead of juggling multiple vendors or middleware tools.
Protocol support alone is not enough; robust platforms must also automate the transformation of EDI documents into whatever format your internal or partner systems require, such as X12, EDIFACT, XML, Excel, or flat files. Nexus VAN’s translation engine allows direct integration with ERP, WMS, and other business software while providing fulfillment tools to streamline shipping workflows and documentation.
Operational risk and downtime cost real money. Nexus VAN guarantees 99.998 percent uptime and SOC 2 compliance, providing confidence in both data security and service availability. Expert support teams offer rapid response (within one business day), which is especially important during onboarding, migration, or high-stakes periods.
Traditional VANs often rely on opaque pricing models, layering on mailbox fees, user charges, partner add-ons, and non-transparent surcharges. Nexus VAN offers a straightforward, value-focused tiered pricing model billed by kilo-character—charging you only for the exact data transmitted, with no rounding, transaction multipliers, or extra fees. This approach delivers savings that commonly reach 40–80 percent compared to typical legacy VAN arrangements.

Many organizations have migrated from legacy VANs and siloed B2B messaging providers to Nexus VAN, achieving cost savings and improved operational efficiency. For example:

A B2B messaging platform securely automates the exchange of business documents such as orders, invoices, and shipment notices between your systems and those of your trading partners. The best platforms support multiple protocols (AS2, SFTP, REST APIs, and VAN interconnects) to maximize compatibility and reliability.
Nexus VAN supports AS2, SFTP, REST APIs, and legacy EDI VAN mailboxes, providing direct connectivity to every major VAN worldwide. Unified data translation ensures all partners and systems can connect regardless of protocol preference or EDI format.
Most Nexus VAN customers achieve 40–80 percent cost savings compared to their legacy VAN contracts. This is due to true usage-based (kilo-character) billing with no setup, onboarding, mailbox, partner, or document fees.
