For incident response teams
Share IOCs and breach packets
without expanding the incident.
Share. Track. Witness.
Incident artifacts move fast and need defensible audit trails. CIPH4 is the channel between your IR team, regulators, and external vendors that doesn't leak the data while you're investigating the leak.
THE CHALLENGE
The problem
What teams in this role actually run into when secure transfer goes wrong.
01
Sloppy channels expand the incident
Coordinating with external vendors, regulators, and partner SOCs under a 72-hour notification window is the moment everything else gets sloppy. Slack DMs, email forwards, ad-hoc Zoom screen-shares — every one is a potential expansion.
02
Chain of custody is the second pressure
Every artifact you share needs to be reproducible later — for the breach report, for litigation, for the post-mortem. A screenshot of a Slack thread isn't a forensic artifact.
03
Your SIEM logs access, not artifacts
SIEMs and ticketing systems track what your team did; they don't carry the actual breach packet or the forensic file between you and an external partner. That transfer ends up in email or Slack — and a partner who mishandles the IOCs creates a secondary disclosure with your name on the original. CIPH4 plugs into the same incident — your SIEM and ticketing flow stay the single source of truth, CIPH4 carries the evidence and produces the chain-of-custody artifact your post-mortem needs.
THE SOLUTION
What CIPH4 gives you
The product surface that maps to those problems, one feature at a time.
01
Per-IP allow / block rulesEnterprise
Pin recipient access to your partner SOC's network ranges before you share the IOC packet. Per-org allowlists or personal blocks; enforcement-cache invalidation fires immediately on every rule change.
02
Webhooks into your IR runbookEnterprise
HMAC-signed webhook fires on the events that matter — viewed, burned, revoked, expired, delivery-anomaly. Wire into your SOAR or SIEM so the access trail lives next to your incident timeline.
03
Tamper-evident audit trail
Every action is timestamped and cryptographically linked to the prior event. Tampering breaks the chain on the next continuous-verify sweep.
04
Signed deletion receiptsEnterprise
Anchored to the audit chain. Every Enterprise drop closure produces a signed receipt — your chain-of-custody artifact at engagement close.
05
Modify after sendTeams
Revoke an active drop the moment the engagement pivots. Tighten view caps, force a passphrase, or burn outright. Useful when a vendor's involvement turns out broader than planned.
06
Behavioral threat detectionEnterprise
Geo anomalies, brute-force, link forwarding, rapid-access bursts, unusual access times, enumeration, and per-creator baseline anomalies. Surface attempted access against your IOC drops the same way you'd surface it against production assets.
THE FLOW
How a typical workflow looks
A typical sequence — from intent to evidence — in three steps.
01
Open
Incident commander stages the initial IOC packet as a multi-file drop. Sets per-IP allowlist to the partner SOC's egress range and passphrase delivered via separate channel.
02
Track
Webhook fires the moment the vendor opens the link. Your SOAR receives the event; your SIEM logs the access against the incident ID. The audit chain captures the same.
03
Witness
At engagement close, burn the drop. Pull the Ed25519 deletion receipt and attach it to the breach report. The chain-of-custody artifact survives every later review.
THE FRAMING
Where CIPH4 fits your program
How the same building blocks land against the frameworks your auditor cares about.
01
Frameworks we map
Breach-notification statutes (GDPR Article 33: 72 hours; US state laws: 30-90 days), industry rules (HIPAA breach notification, PCI-DSS §12.10), and contractual SLAs.
02
Controls we ship
Per-IP allowlists, tamper-evident webhooks into your IR runbook, hash-chained audit log, and behavioral threat detection.
03
Artifacts we generate
Signed deletion receipts and hash-chained audit log — the technical evidence those statutes ultimately rest on. Cryptographically defensible, verifiable on our public /verify page.
