Attic Security
Continuous Microsoft 365 hardening
Attic Security is our platform for continuous monitoring and hardening of Microsoft 365 environments. Automatic detection of misconfigurations and suspicious behaviour.
What is Attic Security?
Attic Security is our own platform for continuous monitoring and hardening of Microsoft 365 environments. Where a one-time review is a snapshot, Attic provides ongoing insight into the security status of your tenant. Configuration changes, deviations from best practices, suspicious behaviour - Attic detects it automatically and alerts you.
We built Attic out of frustration. After pentests and reviews we saw organisations reverting to insecure configurations. An administrator changes a conditional access policy, Microsoft pushes a new feature, someone creates an exception - and security erodes. Attic prevents that.
What does Attic Security monitor?
- Configuration drift - detection when security settings change: conditional access, sharing settings, mailflow rules.
- Suspicious activity - unusual logins, mail forwarding to external, bulk downloads, admin role changes.
- Compliance status - continuous comparison with CIS Benchmarks and Microsoft best practices. Dashboard with compliance score.
- Shadow IT - OAuth consent for third-party apps, unauthorised connectors, unknown service principals.
- Alerting - real-time alerts for critical changes or suspicious behaviour. Email or webhook.
Why Attic Security?
Security is not a one-time action. It is an ongoing process:
- Configuration drift is inevitable: administrators make changes, Microsoft pushes updates, features are enabled - your security changes continuously.
- Fast detection: the faster you detect an insecure change, the faster you can act.
- Continuous compliance: regulators increasingly ask for continuous monitoring, not just periodic assessments.
- Deeper than Secure Score: Attic focuses on what actually poses risk, not Microsoft's own checklist.
Our approach
Attic Security is built by pentesters, for the organisations they test:
- Onboarding - connection to your M365 tenant via read-only API. No agents, no installation.
- Baseline - initial scan to map your configuration and create a baseline.
- Continuous monitoring - 24/7 monitoring of configuration changes, suspicious activities and compliance deviations.
- Alerting & reporting - real-time alerts for critical deviations. Monthly reporting with trends and recommendations.
- Expert support - questions about findings or help with remediation? Our M365 researchers are available. Short lines, direct contact.
What does Attic Security cost?
Monthly subscription, depending on the number of users in your tenant. Contact us for a quote. Many clients start with a Microsoft 365 Review (€3,000 package price) and then transition to continuous monitoring.
Frequently asked questions
Is Attic Security a replacement for Microsoft Defender?
No. Complementary. Defender protects against malware and threats. Attic monitors configuration and detects misconfigurations and policy deviations. We also check whether Defender itself is correctly configured.
What data does Attic Security have access to?
Read-only API access. No access to the content of emails, files or chats. We only read configuration settings, audit logs and policy configurations. Privacy-conscious by design.
Can we connect Attic Security to our SIEM?
Yes. Alerts via webhook - integration with Sentinel, Splunk, Elastic is straightforward. Email notifications also available.
