## What Attic does

Most breaches do not start on the network. They start with an account: a forwarding rule in a mailbox, a stolen token after phishing, a consent screen someone clicks away too quickly. Microsoft Defender usually does see those signals, but rates them Low or Informational. With an IT team of zero to two people, that is where they stay.

That is where IVON comes in. IVON picks up those signals, performs the first triage, investigates what is happening and proposes an action. Attic carries it out after the customer signs off, or automatically for the action types the customer released in advance. What an organisation is left with is not an alert to figure out for itself, but a closed case with a trail it can read back.

- Self-service onboarding, live within 5 minutes
- Microsoft 365-native, no extra agents on endpoints
- Verdict with evidence within minutes, remediation after your sign-off or automatically if you switch that on
- Escalation by email, webhook or push notification. Attic does not call you.
- Continuous hardening with drift detection and one-click fixes
- Transparent pricing on the site, no minimum number of users, with a fixed entry price up to 5 users

Attic does not make an organisation compliant. It does cover the part that NIS2 and the Dutch Cyberbeveiligingswet expect operationally: actually handling incidents, so they can be reported in time.
