“Will our backups actually restore?”
Start with Acheron Vault. Ephemeral restore verification and timestamped proof reports.
OBSIDIAN DYNAMICS LIMITED · UK
Infrastructure software for teams who need proof, not promises.
We build three focused products — backup recoverability, Linux fleet integrity, and webhook delivery control. For platform engineers, SREs, and security teams running production systems.
PRODUCTS
Three problems. Three tools.
Each product solves one infrastructure gap. No bundled platform, no side projects. Pick the pain that matches your team.
BACKUP RECOVERABILITY
Acheron Vault Early access
Best for: Teams who cannot prove backups restore under real conditions.
Backups run on schedule. Nobody has documented evidence they recover when it matters.

LINUX INTEGRITYBlackglass
Best for: Platform and security teams managing Linux fleets at scale.
Configuration drift goes unnoticed until an incident, a breach, or an audit question.
Explore Blackglass →
WEBHOOK RELIABILITYCharon Gate
Best for: Teams receiving inbound webhooks from payment, identity, or SaaS providers.
Events drop during deploys. Retries are inconsistent. Replay is manual and untracked.

ROUTING
Not sure where to start?
Match your gap to a product. You can run one or all three — they are independent tools, not a platform bundle.
“What changed on our Linux hosts?”
Start with Blackglass. Baselines, drift with severity, audit-ready evidence exports.
“We keep losing webhook events.”
Start with Charon Gate. Durable ingest, retries, dead-letter queue, and controlled replay.
TRUST
Built to be audited, not marketed.
Honest semantics, tenant isolation, and evidence trails. We say what ships and what does not.
Tenant isolation
Every query is scoped. Exports and replays stay inside the workspace boundary.
Honest semantics
At-least-once delivery, advisory findings, plain language on what each product guarantees.
Evidence trail
Timestamps, signed deliveries, and exports your auditor or incident lead can act on.
WRITING
Technical notes from the team.
Essays on the problems we build for — with links to the products they inform.
ACHERON VAULT
What a real backup test looks like
Running pg_dump on a schedule is not a backup test. A real test performs an actual restore and produces evidence.

BLACKGLASSLinux fleet baselines, explained
A baseline is the picture of a server you agreed was fine. Everything else is downstream of that idea.

CHARON GATEA short webhook reliability primer
HMAC, immediate ACK, jittered backoff, DLQ, replay — the five primitives of a production webhook handler.
