No alert goes unanswered
Attic MDR watches the Microsoft 365 environment of organisations that have no SOC of their own. Suspicious sign-ins, mailbox rules and OAuth grants are picked up and investigated, even when Defender rates them low. Every signal closes with a verdict and the evidence behind it. Remediation runs after your sign-off. Connecting takes five minutes.
Most Defender alerts
arrive at low priority
Three examples from Microsoft's own documentation. All three visible in your environment, all three easy to miss in a list nobody watches full time.
A forwarding rule in a mailbox.
Alert policy "Creation of forwarding/redirect rule", severity Informational. If the rule is created from Outlook on the desktop, the policy does not fire at all.
A stolen session token after phishing.
Risk detection "Anomalous Token", severity Low to Medium. Microsoft notes itself that this detection is "historically tuned to incur more noise than other detections".
Someone searches every mailbox in the organisation.
Alert policy "eDiscovery search started or exported", severity Informational.
So they are there. The question is who opens them.
From signal to verdict to remediation
Attic MDR is the service. IVON is the agentic layer that does the work.
- 1
Everything comes in.
Signals from Defender, Entra ID and the Microsoft 365 audit log arrive as they are, whatever severity is on them. Nothing is filtered out up front for scoring low.
- 2
IVON investigates.
The agent picks up the signal, works out what happened and closes it with a verdict and the evidence underneath. Within minutes, at night and at weekends too. A human handles the exceptions, not the stream.
- 3
Remediation after your sign-off.
IVON proposes the fix and carries it out once you approve. We do not call: notifications and escalations go by email, webhook or a push message in the Attic app.
What a customer actually notices
The customer wrote this in Dutch.
"We hadden bijvoorbeeld een alert over een medewerker die tien bestanden in één keer downloadde, met severity high. IVON had dat onderzoek in vijf minuten afgerond en kon precies aantonen dat het gewoon haar eigen trainingsmateriaal en sjablonen waren, gedownload vanaf haar eigen compliant device thuis. Geen collega die daar eerst zelf in moest duiken." What it costs
Attic MDR starts at 30 euro per month, for up to 5 users. Above that you pay 6 euro per user per month, and the more users you have, the lower that rate gets. Cancel monthly, 10 per cent off on an annual subscription. The price is on the site, so you do not have to ask for it.
