Barrier count is the number of independent cryptographic objects that must all be defeated
to recover one protected record. It rises by three at every step: one more cryptographic
level, one more containment sphere, and that sphere's own independent encryption.
Tier 1
AMBER
Baseline containment for data whose disclosure is inconvenient rather than material.
- Barriers
- 1
- Spheres
- 1 white-noise containment sphere
- PQ families
- None — classical strength only
- Self-healing
- No
- Key rotation
- Every 90 days
- Standards
- FIPS 197 · FIPS 198-1 · FIPS 180-4 · RFC 5869
- Price
- $2.50 per node, per year
Every record is encrypted and authenticated before it is written, and a record altered by
a single bit fails to open rather than opening wrong. This is the floor of the ladder,
and it is stated as a floor: it carries no post-quantum protection at all.
For: internal tooling, low-sensitivity logs, non-regulated operational data.
Tier 2
SAPPHIRE
Post-quantum key establishment for anything that crosses a wire.
- Barriers
- 4
- Spheres
- 2 self-healing containment spheres
- PQ families
- 1 — lattice key encapsulation
- Self-healing
- Yes
- Key rotation
- Every 30 days
- Standards
- Tier 1 · FIPS 203
- Price
- $10.00 per node, per year
Key establishment is hybrid: an attacker must break lattice mathematics and
elliptic-curve mathematics, in the same session, to recover a key. This is the tier that
answers harvest-now-decrypt-later — traffic captured today stays closed later, because
breaking one family is not enough.
For: schools and universities, SaaS in transit, partner integrations, public APIs.
Tier 3
EMERALD
Two post-quantum signature families on every record, and both must verify.
- Barriers
- 7
- Spheres
- 3 self-healing containment spheres
- PQ families
- 2 — lattice KEM, and two signature families
- Self-healing
- Yes
- Key rotation
- Every 14 days
- Standards
- Tier 2 · FIPS 204 · FIPS 205
- Price
- $17.50 per node, per year
Integrity is signed twice, by families resting on unrelated mathematics. Both signatures
must verify or the record is refused. This is the lowest tier at which a signature
failure is a security event rather than a maintenance ticket.
For: financial messaging, medical records, legal instruments, audit trails, evidence.
Tier 4
RUBY
All three post-quantum families, with self-healing containment between every layer.
- Barriers
- 10
- Spheres
- 4 self-healing containment spheres
- PQ families
- 3 — all published families in use together
- Self-healing
- Yes
- Key rotation
- Every 7 days
- Standards
- Tier 3, at full composition
- Price
- $25.00 per node, per year
The three post-quantum families run together, and solid containment spheres sit between
each cryptographic layer. Each sphere carries its own independent encryption, so the
count of things that must be broken is ten, not one. This is the first tier where
containment repairs itself under load.
For: banks and payment networks, insurers, critical SaaS, national retail, utilities.
Tier 5
DIAMOND
Highest-category key establishment inside twelve independently keyed zones.
- Barriers
- 13
- Spheres
- 5 self-healing containment spheres
- Zones
- 12 independently keyed containment zones
- PQ families
- 3, at the highest published security category
- Key rotation
- Every 24 hours
- Standards
- Tier 4 · NSA CNSA 2.0 key establishment
- Price
- $32.50 per node, per year
Key establishment moves to the highest security category the standard defines, and the
protected estate is divided into twelve containment zones holding independent keys with
no shared trust boundary. Compromising one zone yields one zone, and the breach triggers
a re-key of all twelve rather than a page to an operator.
For: critical national infrastructure, defence supply chain, central banking, grid operators.
Tier 6
OBSIDIAN
Sovereign: one holder, one authority, and no administrative override.
- Barriers
- 16
- Spheres
- 6 self-healing containment spheres
- Zones
- 12 independently keyed containment zones
- Authority
- Sovereign credential only — no vendor recovery
- Key rotation
- Every 12 hours
- Standards
- Tier 5 · RFC 7914
- Price
- $40.00 per node, per year
Above this line the operator of the system is not the authority over it. A single
sovereign credential is the only thing that unseals the tier: no support escalation, no
break-glass account, no vendor-side recovery — by construction rather than by policy.
That is a deliberate trade and it cuts both ways. The estate cannot be opened by
coercing an administrator. It also cannot be opened if the credential is lost. Buyers
are briefed on custody before this tier is provisioned.
For: crown-jewel intellectual property, model weights, root key material, board-level records.
Tier 7 · the top of the ladder
TORTOISE
Energy-grade: every barrier sealed at rest, because the failure mode is physical.
- Barriers
- 19
- Spheres
- 7 self-healing containment spheres
- Zones
- 12 zones, sealed at rest rather than on breach
- Authority
- Sovereign credential for every privileged action
- Key rotation
- Every hour
- Rate plane
- Dedicated, not shared
- Price
- $47.50 per node, per year
Every tier below protects information, and their worst case is disclosure. This tier
exists for systems whose worst case is a machine acting on a forged instruction — a
battery told to accept a charge it cannot survive, a breaker told to close on a live
fault, an actuator told to move while a person is inside its envelope.
That is a different threat model, so the posture inverts. All nineteen barriers are
engaged at rest and all twelve zones are sealed before the first request arrives,
rather than sealing in response to a breach. It is the slowest tier by a wide
margin, and it is meant to be: the cost is paid up front, permanently, in exchange
for a system that is never briefly open while it decides to close.
For: grid-scale energy control, industrial actuation, autonomous physical systems, flight and rail.
Tiers are cumulative. A node at Tier 5 holds every protection from Tiers 1 through 4 as
well, which is why the barrier count is additive rather than a choice between options.
