In warehouse operations, secure EDI transmission isn’t optional. It’s the backbone of order flow, shipping accuracy, and compliance.
Every purchase order, ASN, and inventory update depends on reliable data transfer. Choose the wrong protocol, and you risk failed transfers, missed SLAs, and compliance penalties.
Here’s what actually matters when evaluating AS2, SFTP, and HTTPS for warehouse EDI.
Warehouse EDI traffic is constant:
If transmissions fail or lack proper confirmation, the downstream effects are immediate — shipment delays, invoice disputes, and chargebacks.
Your protocol determines:
This is operational infrastructure, not a checkbox decision.
For warehouse environments, four elements matter:
Now let’s compare how each protocol handles those requirements.
AS2 is the most widely mandated protocol in retail and regulated supply chains.
It provides:
For warehouse operations working with large retailers or compliance-heavy industries, AS2 is often required.
Setup requires certificate management and configuration effort. But once deployed, AS2 is highly scalable and reliable. If compliance risk is high, AS2 is typically the safest long-term choice.
SFTP is widely used for secure file transfer in warehouse environments. It offers:
However, SFTP does not natively provide non-repudiation or automatic receipt confirmation like AS2. That means:
For many warehouse operations, SFTP is operationally sufficient — especially when supported by a VAN that adds monitoring and validation.
HTTPS provides encrypted transport over the web. It is secure — but it is not an EDI protocol by itself.
It works well for:
But on its own, HTTPS does not provide:
In many modern architectures, AS2 runs over HTTPS transport, or HTTPS supports API-based EDI integrations. For warehouse EDI, HTTPS is typically part of the stack — not the entire solution.
Here’s the practical guidance.
Most warehouse operations end up using a combination. What matters is that your VAN supports all three cleanly — without forcing partner-by-partner complexity.
Warehouse leaders who have managed EDI long enough know the hidden pitfalls:
Modern VAN providers remove those barriers.
With BOLD VAN:
Security is critical — but so is predictability.
Warehouse EDI transmission should be reliable, compliant, and predictable.
AS2, SFTP, and HTTPS each serve a purpose. The key is choosing a provider that supports all three — and helps you apply them strategically.
If you’re reviewing your EDI transmission model, schedule a demo and see how secure, multi-protocol support can reduce operational risk and eliminate unnecessary fees.
Your warehouse shouldn’t have to think about EDI security. It should just work.
Will partners need to change protocols if we switch VANs?
Not necessarily. A modern VAN can translate and manage connections behind the scenes.
How fast can migration happen?
Many migrations complete within days using parallel testing to avoid disruption.
Will we lose archive access?
No. A strong provider maintains searchable archives for long-term compliance.
Is 24/7 support actually available?
With the right partner, yes — direct expert support, not ticket queues.
