The family

One company. One honesty rule.

Products below are named so a buyer can point. First invoice is still Citadel on a box you own. The others attach after that host, or stay SST-held.

On-prem under white-glove

SST installs, binds a Charter grant, walks out. Catalog items Hermes will stand when the grant and the box exist.

sst_citadel · selling

SST-Citadel

Vendor and internal credentials. Viewer / Editor / Admin. Password versions and an activity log. HA nodes from the UI against shared PostgreSQL — the database remains the SPOF.

sst_hermes · installer

Sigma Hermes

Short-notice deployer. One intake. Azure, GCP, AWS, existing SSH, or local Docker. Rehearsal is the default. Live apply is SST-gated Command. Sealed report; secrets stripped.

sst_signet

Sigma Signet

PDF mark, PAdES-B sign, validate. Saves to the mailbox you already have — OneDrive or Drive — not a Signet content cloud. Demo CA is not a public root.

sst_alembic

Sigma Alembic

Distill living infra into a capture pack (import-only) and a replay pack for a second environment. Coverage is a score. Secrets redacted from the sealed Codex.

sst_janus

Sigma Janus

On-prem → Azure / GCP / AWS crossing. Preflight, operator-gated migrate, post-validate. Does not replace Azure Migrate or AWS MGN. Does not flip DNS.

sst_ira · argus host

Sigma Argus

Self-hosted remote assist. Two-node cluster on a shared database, health-gated watchdog. Shared DB is the remaining SPOF. We write that in the quote.

sst_merlon · appliance

Sigma Merlon

Perimeter box. nftables data plane. Guard / Watch / Seal. Signed generations, integrity watchdog, operator lifeline. Not DPI. Not TLS intercept. Not a first-call SKU.

sst_helios

Sigma Helios

Isolated AI access. Entra + MFA. Separate engines for Excel, boards, financials, general help, and IT fix — zero data sharing across them. Not a public model.

sst_halo · office bubble

Sigma Halo

Staff attach to your nodes — HO, plant, staging VPC. Seats + registered nodes. Not a consumer privacy VPN. Signaling stays SST-held.

SST-held planes

These do not ship to a customer as an install. They are how SST issues grants and runs work we will not hand over.

sst_charter · operator only

Sigma Charter

License office. Mints, validates, revokes. Term starts at generation, not paste. Keep is still $0 and still needs a code. Customers never install Charter.

sst_aegis

Sigma Aegis

Authorized assessment platform. Black / grey / white-box with an evidence pack. Not the vault. Not a first-host product. Control plane stays with SST.
