8 automated checks. 60 seconds. One answer.
Your trading partner says
their cert is fine.
Prove who's right.
AS2 Certify runs a full diagnostic on any AS2 endpoint — TLS, certificates, encryption, signing, MDN, payload — and tells you exactly what's broken and how to fix it. No partner coordination required.
30 seconds to your first result. No credit card. No partner needed.
This is what you get in 60 seconds
A real diagnostic report. Not a ping test. Not a vague "connection successful."
TCP/TLS Connection
Certificate Validation
Encryption Verification
Signing Verification

If you've onboarded an AS2 trading partner,
you already know the pain
40 hours lost per failed onboarding
New trading partner. Export your cert. Email it. Wait 3 days. They configure it. Test. Fail. "Try DER format instead." Another 3 days. That cycle repeats 4-5 times before anyone admits the signing algorithm doesn't match.
Average time to resolve: 2-5 business days
MDN failures with zero useful context
The log says "MDN verification failed." Is it the signature algorithm? The certificate chain? A content-type mismatch? An intermediate cert your CA forgot to mention? Nobody on either side can tell you. So you both guess.
Most common support ticket in EDI operations
Compliance deadlines that don't move
DSCSA serialization is live. Walmart's EDI requirements are non-negotiable. Your AS2 connection is "almost working" but the deadline is Friday. Your trading partner's IT team is out until Monday.
DSCSA non-compliance: up to $10M in penalties
Don't wait for your trading partner
The average AS2 partner onboarding takes 40+ hours. 60% of that time is waiting for the other side. AS2 Certify simulates your trading partner so you can validate your setup on YOUR schedule. Test outbound, inbound, or full round-trip without any coordination.
Find the problem in minutes. Fix it before the meeting.
Point AS2 Certify at any endpoint. Get a complete diagnostic before your next call.
Test without your trading partner
Our sandbox simulates your trading partner, sending and receiving AS2 messages exactly like a real partner would. No coordination. No waiting. Validate your setup on your schedule.
8-step automated diagnostic
TCP/TLS, certificate chain, encryption, signing, AS2 message exchange, MDN receipt, payload integrity, and latency. All tested automatically in under 60 seconds.
Reports that explain the fix
Every check shows pass, fail, or warning with the exact reason. "Your certificate uses SHA-1 signing but your partner requires SHA-256" instead of just "MDN failed."
Catch certificate problems first
Expired certs, wrong key sizes, missing intermediates, format mismatches, and chain validation issues, all caught before you spend a week debugging at the connection level.
AI assistant with your knowledge built in
Upload your AS2/EDI documentation and get answers specific to your setup. Not a generic chatbot, but an assistant that draws from your industry knowledge base.
Knowledge base for your team
Upload partner setup guides, compliance docs, and configuration references. The AI assistant uses them to give accurate, context-aware answers about your specific connections.
Three steps. No partner coordination needed.
Test your endpoint independently. Know what's wrong before you email anyone.
Configure your endpoint
Enter your AS2 ID and endpoint URL. Upload your certificate in any format (PEM, DER, PKCS#12, JKS). We validate key size, expiration, and chain integrity automatically.
Launch the partner simulator
Our sandbox acts as your trading partner, sending and receiving AS2 messages exactly like a real partner would. Test outbound, inbound, or full round-trip.
Get your diagnostic report
In under 60 seconds you get an A-F grade, pass/fail on every check, specific fix guidance, and an exportable report. Know exactly what’s working before your real partner comes online.
Works with your AS2 platform
AS2 Certify tests against any RFC 4130-compliant endpoint, regardless of which platform your trading partner runs.
$99/mo vs. 40 hours of engineer time
A single failed AS2 onboarding costs your team 2-5 engineer-days at $150/hr.
That's $2,400-$6,000. AS2 Certify pays for itself the first time you use it.
