IronSeal

Out-of-band · Break-glass · Incident response

When your network is compromised, you can't coordinate the response on it.

IronSeal is the out-of-band communications channel your incident response team trusts when email, Slack, and Teams can't be.

The problem

The moment you suspect a breach, every message you send over corporate channels could be read by the attacker. Your response plan becomes their early warning.

A threat actor with a foothold may already hold mailbox access, valid Slack/Teams session tokens, and presence on your endpoints. Coordinate containment on those channels and you hand the intruder your playbook — time to destroy evidence, accelerate exfiltration, or deploy ransomware ahead of your response.

These channels share fate with the environment under investigation: same identity provider, same vendors, same network. You cannot investigate a house using the intruder's intercom. The response has to move to a channel that lives entirely outside — one the attacker cannot reach and cannot already have compromised.

Why IronSeal for IR

Built like a break-glass channel — existing capabilities, mapped to the incident.

INFRASTRUCTURE

Zero infrastructure dependency

No agent, connector, or integration inside the corporate network. Nothing on your side for the attacker to compromise to reach it. Responders open it from any clean device.

CONFIDENTIALITY

Zero-knowledge — nothing to steal

Messages are ECDH P-256 + AES-256-GCM encrypted on-device. The server stores ciphertext only — no plaintext field exists. A breach of our own infrastructure yields unreadable blobs.

ATTACK SURFACE

Text-only, no malware vector

During an active incident you cannot trust any file. IronSeal transmits encrypted text only — the entire attachment attack category is removed from the response channel itself.

ACCESS CONTROL

Biometric-gated access

Reading a message requires a fresh WebAuthn biometric. On a shared, borrowed, or seized device, an unlocked screen does not expose the response thread.

CHAIN OF CUSTODY

Tamper-evident audit log

SHA-256 hash-chained events record who and when — never content. A defensible, verifiable record of the coordination for post-incident review and legal proceedings.

DEVICE SEIZURE

Self-destruct on failed access

Repeated failed authentication trips a dead-man's switch: messages purge and both parties are notified. A lost device mid-incident does not quietly wait to be read.

What IronSeal is not

The honest boundaries — because a tool that oversells is worse than useless at 02:00.

Security professionals read critically, and they should. Here is exactly where IronSeal stops. If any of this rules it out for you, better to know now than mid-incident.

  • ×A SIEM, EDR, or threat-detection tool. It is a communications channel — one component of an IR toolkit, alongside the platforms that detect and respond.
  • ×A defense against a fully compromised endpoint. If a responder's own device carries a kernel-level implant or screen-capture malware, it sees what they see. Use IronSeal from a device you trust.
  • ×Metadata-hiding, today. The server sees no content, but it does see which accounts communicate and when. Assume timing and communication-graph metadata are observable.
  • ×A replacement for your IR platform. It is the out-of-band comms layer, specifically — not the whole program.
Framework alignment

Maps to the phase where secure coordination is the need — silent on the phases it has no business claiming.

NIST SP 800-61

Supports the Containment, Eradication & Recovery phase by enabling the IR team to coordinate over a channel the attacker cannot observe. Provisioned during Preparation; deliberately absent from Detection & Analysis, which your SIEM/EDR own.

Chain of custody

The hash-chained, tamper-evident audit log provides a verifiable, content-free record of when coordination happened and who participated — supporting the Post-Incident Activity review, regulatory notifications, and any subsequent legal process.

You cannot provision a break-glass channel during the breach. Pre-provision your responders, document the activation criteria, and rehearse the switch.
