Composable security operations

One quiet platform.
Complete coverage.

Detection, response, and compliance in a single place — built to remove noise, not add to it.

Encrypted by default

Customer data sealed with per-tenant keys, hardware-backed and rotated automatically.

Detection that
reads the landscape

Overnight, Cairn keeps watch

Most intrusions begin after hours, when nobody is looking at a dashboard. Cairn doesn't need anyone looking. It correlates signals across your whole estate, decides what's real, and acts within minutes — leaving a complete, human-readable trail for the morning.

  • Correlated, not collected. One verdict per incident, not four hundred raw alerts.
  • Reversible actions first. Isolate and revoke before anything destructive — always undoable.
  • Wake-up worthy only. Pages go out for the 0.3% of events that truly need a human.

Evidence, always ready

Audits become an afternoon, not a quarter

Every control Cairn enforces is logged as evidence the moment it happens. When the auditor arrives, your SOC 2 and ISO 27001 binders are already written — mapped, timestamped, and exportable in one click.

  • Continuous control monitoring across 140+ mapped requirements.
  • Drift alerts the day a control slips, not the week before renewal.
  • Auditor portal with scoped, read-only access — no more zip files over email.

Waves washing over a quiet shore

"We went from three pager rotations to one. The first quarter on Cairn, my team handled nine incidents instead of two hundred — and every one of them was real."

Our SOC 2 renewal took four days of prep instead of six weeks. The auditor asked what changed.

It contained a credential-stuffing run at 3 a.m. and I read about it over breakfast. That's the product.
