Trusted infrastructure

Security by design

Trust boundaries enforced at every layer — between tenants, zones and management planes.

Built to protect. Designed to assure.

Lit Calliseom data-center campus

Cyber & data

Zero trust

No implicit trust between tenants, zones, or management planes.

Tenant isolation

Dedicated VLAN / VRF per client; bare-metal GPU with no shared hypervisor on dedicated tiers.

Network defense

DDoS scrubbing at the edge; management network fully out-of-band and segmented.

Encryption

In transit and at rest; customer-held keys — Calliseom holds no tenant key material.

SOC 24/7

Continuous monitoring, SIEM, defined incident response and escalation.

Supply chain

Vetted hardware sourcing; no untrusted-jurisdiction components in the critical path.

Physical — five layers of protection

Underground is not a feature. It is the security perimeter.

1
Perimeter
Anti-ram fencing, vehicle barriers, thermal and AI video analytics, 24/7 patrol.
2
Site
Single controlled vehicle entry, inspection point, no direct approach to hall structures.
3
Building
Mantrap airlocks, anti-tailgating, blast-rated entry, no ground-level access to halls.
4
Underground halls
16–20 m below grade — unreachable by vehicle, drone, or standoff attack.
5
Rack / cage
Biometric + card dual-factor at cage level, per-rack electronic locks, full audit trail.
Multi-layer physical protection rings around the campus
Biometric access

Multi-modal (fingerprint + facial); mandatory dual-authorization for MMR, electrical and NOC.

Full CCTV coverage

No blind zones; retention to design specification.

SOC 24/7

Co-located with the NOC, single incident command.

Compliance by design. Proof, built in.
