Antifragile Cybersecurity
Open-source M365 governance tools. Practical consulting. Security that grows stronger from disruption.
The M365 Governance Suite
Three complementary tools — PULSAR, ASTRAL, and AURORA — that together answer every question about what happened and what changed in your Microsoft 365 tenant.
| Product | What it answers | Model |
|---|---|---|
| PULSAR | What happened, when, and by whom? | Free & Open Source |
| ASTRAL | What does my config look like, and what changed? | Free & Open Source |
| AURORA | What does it mean and what should I do? | Commercial |
PULSAR
Continuous M365 audit log ingestion with indefinite retention, search UI, REST API, alerting, SIEM forwarding, and an MCP server for AI-assisted queries.
ASTRAL
Git-tracked snapshots of M365 configuration. Automatic drift detection, PR-based review workflow, baseline restore, and indefinite history.
AURORA
A unified AI-assisted layer connecting PULSAR and ASTRAL. Cross-tool diagnostics, multi-scope support, enriched SIEM forwarding.
Security That Grows Stronger
Consulting and strategic services built on one principle: every disruption should leave your organisation more capable than before.
Antifragile Consulting
The Brownhat methodology — start with what you own, close the kill chain, build retained capability. Modular engagements from 30 days upward.
Virtual CISO & Security Architect
Fractional security leadership for organisations that need strategic direction without a full-time hire. Risk ownership, board reporting, vendor governance.
Housekeeping as a Service
A dedicated rented team that drains your attack surface continuously. Client-Directed for steady attrition, Kill-Chain for collapsing existential paths fast. The sign flip from growth to decay.
