Product briefing
ComputingSphere DNP3
A focused tool for passive DNP3 traffic inspection — bring a capture in, and get a decoded, cataloged, report-ready session out.
End to end
One session, five stages, zero spreadsheets
A capture goes in one side of ComputingSphere DNP3 and a signed-off report comes out the other. Here's what happens to it in between.
Bring your traffic
Upload a PCAP or point at a live link. Every session is tracked with packet count, time window, and status.
Read every frame
Raw bytes and decoded DNP3 side by side, down to the Data Link, Transport, and Application layers.
See the pattern
Function-code and IIN breakdowns, side-by-side capture comparisons, and link efficiency at a glance.
Name what you found
Every Master, Outstation, and analog point lands in a live device inventory — no spreadsheets to keep in sync.
Hand it off
One click exports a client-ready PDF — connection overview, statistics, and every IIN flag observed.
See it in action
DNP3, decoded
A walkthrough of ComputingSphere DNP3 — importing traffic, browsing devices, comparing captures, and generating reports.
No account needed
Paste a DNP3 frame, see it decoded
This is the same parser the platform runs on every capture. Paste up to 10 hex-encoded DNP3 frames below, one per line, and see exactly what it sees.
