D-KaP Sync — the EpochCore product that gives you a live, always-on stream of sealed compliance events mirrored continuously into a write-once archive — means that when the auditor asks "show me what happened at 03:14 on the 12th," the answer is one query away. It is part of EpochCore's sealed-evidence product line.
Point-in-time compliance evidence is fragile. Auditors increasingly want continuous monitoring — proof that every relevant state change in your environment was recorded the moment it occurred, not the day before the audit. Most companies fall back on log scraping and cron jobs, which leaves gaps. When a regulator asks "show me the exact moment your access policy changed last quarter," scrolling through CloudTrail at 2 a.m. is not a defensible answer.
D-KaP Sync is an always-on stream. Each event in your environment — login, config change, deploy, access grant, transaction — comes through a live WebSocket feed, gets signed in real time, and is written to a write-once archive (meaning once a record is in, no one, including us, can edit or delete it). The signature is anchored to the EpochCore root certificate, so when an auditor or regulator pulls an event months later they can verify it has not been tampered with since the moment it was recorded.
You subscribe once. Every event is sealed continuously. The audit log builds itself.
GET /sync/ws, signed JSON line per event, reconnect-safe with replay.Connect your service (Node, Python, Go, anything that speaks WebSocket) to GET /sync/ws with your API key. Most teams add this in their existing event pipeline as a side-channel.
Every state change you push to the stream is sealed and archived as it arrives. There is nothing to schedule, no cron job to babysit, no log file to rotate. If the connection drops, Sync will replay missed events on reconnect.
When the auditor wants to see "everything that happened in the access-control system between March 1 and March 31," you give them a verification URL with the time window. They confirm each event's seal and the time-ordering is intact. Question closed.
Example: A healthtech SaaS company has a SOC 2 Type II finding flagged: "no continuous evidence of access-control change events." They pipe their identity-provider webhook into D-KaP Sync. Three months later, the auditor returns and asks for every IAM policy edit in Q1. The compliance lead pulls a single date range; every event is sealed, ordered, and verifiable on first review. Finding cleared.
The alternative is a self-built pipeline: storage, ordering, signing, retention, and a verifier the auditor will accept. That is months of engineering time for what is fundamentally undifferentiated work. Sync is the lowest-friction way to clear a "continuous monitoring" control without building a logging product from scratch.
Add an invisible watermark to the auditor-export bundle (the rolled-up PDF + JSON your auditor receives when they query a time window). The watermark stays attached through screenshots, re-uploads, and ordinary compression. We measured it against 136 attack vectors and it survived 90 of them with zero false positives, while remaining invisible (image quality 0.985 of 1.0). MEASURED
Useful if your exported audit timelines circulate across vendor diligence portals, regulator submissions, or insurance claims and you need a way to prove which copy is the canonical one. Not "uncopyable" — a determined attacker can still strip a header — but tamper-evident in every way that matters to a compliance review.
