Distribute any proprietary software, compiled binaries, core algorithms, business engines, and AI workloads directly into customer-owned cloud (BYOC) & VPS environments with flexible product-to-tier license mapping. Seamlessly map commercial editions, module add-ons, and concurrency limits into cryptographic silicon policies (AWS Nitro, AMD SEV-SNP, Intel TDX)—keeping your intellectual property 100% sealed against reverse engineering while customers preserve absolute data sovereignty.
Traditional SaaS and conventional on-premise models force dangerous compromises between customer data sovereignty and vendor IP protection.
| Operational Dimension | Pure Cloud SaaS | Traditional On-Premises / VM | VastarFort BYOC Confidential Computing |
|---|---|---|---|
| Customer Data Sovereignty | Low Sensitive data is transmitted to vendor cloud over the public internet. | High Data remains on customer physical premises. | Absolute (100% Local) Data never leaves customer private VPC/VPS memory. |
| Vendor IP Security (Binaries, Algorithms & Business Logic) | High Proprietary code resides only on vendor internal infrastructure. | Zero Unprotected binaries surrendered; root admins can attach debuggers (gdb/ptrace), decompile algorithms, or patch licenses. | Absolute (100% Sealed) Code and algorithms decrypt strictly in TEE RAM (via memfd_create); host disk never sees plaintext. |
| License Enforcement & Concurrency Caps | Software Only Relies on coarse external API rate limiters. | Fragile License files or dongles are trivially patched by root admins. | Hardware-Enforced Declarative multi-tier mapping with atomic CAS semaphores inside isolated enclave memory. |
| Cloud Infrastructure Cost Burden | Very High Vendor must fund customer compute & server infrastructure. | High Customer purchases expensive specialized hardware appliances. | Optimal Customer utilizes existing cloud/VPS quota; Zero server costs for Vendor. |
| Enterprise Sales Cycle | Prolonged (6–18 months) due to compliance & legal data security hurdles. | Fast for buyer, but vendors hesitate to deliver crown-jewel algorithms and proprietary IP. | Frictionless Enterprise Sales: Instant regulatory compliance (GDPR, HIPAA, PDP). |
VastarFort delivers complete deployment freedom: run on global hyperscalers or dramatically reduce operating expenses using budget-friendly Confidential VPS providers powered by AMD SEV-SNP and Intel TDX.
Onidel offers Premium VPS with AMD EPYC processors and native AMD SEV-SNP with zero feature surcharge. An exceptional solution for running vastarfort-node with full hardware memory encryption at budget-friendly operational rates starting from ~$9.90/month.
Supports custom Unified Kernel Image (UKI) upload with measured OVMF firmware, validating OS authenticity before runtime keys are unsealed.
Physical memory is encrypted at the hardware controller level by the AMD Secure Processor with unique per-VM keys. Hypervisors are locked out.
Engineered for cold-restore reboot cycles without insecure live-migration risks; every restart triggers fresh remote attestation verification.
Comprehensive profile support: AWS Nitro Enclaves (x86_64 c5/c6i and Graviton aarch64 c7g/m7g), AMD SEV-SNP (c6a/m6a), and NitroTPM.
/dev/nsmSupports GCP Confidential Space (N2D/C2D/C3) and Azure Confidential VMs (DCasv5/ECasv5 with AMD SEV-SNP and DCesv5 with Intel TDX).
Dedicated physical servers with AMD EPYC (Milan / Genoa) or Intel Xeon Scalable CPUs hosted at Hetzner, OVHcloud, and Equinix Metal.
vastarfort-nodeSelect a processor architecture below to inspect cryptographic attestation mechanics and TCB registers enforced by VastarFort:
Secures guest memory with hardware-grade AES-128/256 encryption using unique per-VM keys managed by the AMD Secure Processor (ASP), blocking hypervisors and root administrators.
SEV-SNP attestation reports are verified hermetically. Strict anti-downgrade policies ensure VLEK shared reports cannot bypass dedicated host VCEK contracts.
Isolates enclave CPU and memory from the primary parent host kernel via the Nitro PCIe Security Card. The parent host provides only a VSOCK proxy and is blocked from reading enclave RAM.
The canonical verifier crate inspects the AWS x509 cert chain, cross-checks PCR digests against publisher-signed manifests, and releases the CEK share exclusively wrapped in the enclave's ephemeral key agreed in guest RAM.
Isolates Trust Domains (TD) from the Virtual Machine Manager (VMM) and host hardware via specialized processor firmware (TDX-SEAM).
The wire protocol enum TEE_TARGET_INTEL_TDX = 2 is integrated in wire contracts and ready for hyperscaler TD quoting enclaves in GCP C3 or Azure DCesv5.
Enforces Measured Booting with virtualized TPM 2.0 cryptographic processors authenticated by the Nitro Security Chip.
Tailored for hardened EC2 instances. NitroTPM documents are rejected when presented to enclave policies to prevent cross-backend substitution.
Vendors with multifaceted product portfolios and diverse commercial tiers (Starter, Professional, Enterprise, Add-on Modules) gain an unambiguous mapping pathway into cryptographic silicon TEE policies. Zero payment gateway lock-in, with fine-grained feature flags dynamically gated in guest RAM.
Map commercial catalog editions and SKU variants (Starter, Professional, Enterprise, Add-ons) into the cryptographic RuntimeLicenseBinding v1. Each tier binds product_id, edition_id, and execution privileges without modifying binary code.
Concurrency limits (e.g. Max N=2 workflows for Starter vs N=50 for Enterprise) are strictly enforced in guest enclave RAM via atomic fetch_update loops (WorkflowSlotGuard). Zero race conditions, zero host bypasses.
Dynamic feature-claim vectors (e.g. ["batch_processing", "vector_acceleration", "realtime_eval"]) are sealed inside the lease token (SignedLeaseToken v2). Features unlock or revoke dynamically in RAM without recompiling separate binaries.
Customer tier upgrades from Standard to Enterprise are applied in-place via the TierTransitionCoordinator. Customers enjoy instant upgrades without downtime, without restarting virtual machines, and without privilege escalation loopholes.
Runtime leases operate under tight bounded durations (lease TTL 60s) guarded by monotonically increasing fencing_epoch counters. Customers cannot freeze VMs, manipulate system clocks, or replay stale historical snapshots.
VastarFort never processes payments or touches credit cards. Commercial transactions remain 100% inside the Vendor's own billing portal (Stripe, corporate invoicing, wire transfers). VastarFort purely verifies the signed Ed25519 cryptographic authorization grant.
Click a commercial tier below to observe how Vendor product catalog definitions map declaratively into the cryptographically enforced RuntimeLicenseBinding v1 inside enclave silicon RAM:
Tailored for department-scale workloads or internal evaluation. Caps execution at baseline compute capacity with core features enabled.
Binary executes inside the hardware TEE (Onidel SEV-SNP or AWS Nitro). Advanced features outside the tier (such as batch pipelines or SIMD acceleration) remain disabled in memory. Attempting a 3rd concurrent execution is immediately gated by the atomic WorkflowSlotGuard without requiring external cloud calls.
Designed for heavy production throughput with compute vector acceleration and high-volume parallel pipelines.
The vector_simd acceleration engine and batch_pipeline processor unlock directly in RAM by the EAR supervisor. The 25-slot quota is guarded hermetically; overflowing requests queue deterministically without memory faults.
Engineered for financial institutions, banking, and sovereign mission-critical operations. Includes cryptographic audit streams, absolute memory isolation, and multi-node scaling.
Unlocks the complete suite of enterprise capabilities, hardware security module (HSM) custody keys, and immutable cryptographic audit logging. Enforces strict hardware silicon attestation to bind execution to specific registered servers.
Per VastarFort canonical specifications, three entities operate across decoupled security domains with zero single points of superuser control.
Provider and operator of the VastarFort Hub SaaS platform. Operates as the Zero-Knowledge Trust Broker, physical TEE verifier authority, managed node quota allocator, and durable revocation coordinator. Vastar never observes proprietary binaries or private customer data.
Hub tenant and creator of proprietary software, core computational algorithms, enterprise engines, or AI workloads. Uses vastarfort-publisher to seal binaries into encrypted OCI chunks, holds private Ed25519 signing keys, maps commercial product tiers and SKUs to cryptographic TEE policies, and retains complete sovereign custody over distribution rights.
Client of the Vendor who provides compute capacity (AWS EC2, GCP, Azure, or private VPS like Onidel/Hetzner). Exercises affirmative Customer Consent over when workloads launch. The hypervisor and host root administrators reside strictly outside the Trusted Computing Base (TCB).
Complete structural isolation between license governance supervision and protected proprietary application execution in encrypted enclave memory.
Lightweight in-enclave supervisory daemon. Coordinates outbound communication over VSOCK (Port 5007), harvests genuine physical attestation reports, and enforces license duration (lease TTL 60s) with epoch fencing against rollback attacks.
Hermetic execution vessel where proprietary binaries, algorithms, and models run strictly in RAM (memfd_create). 4 MiB encrypted chunks stream from the registry and decrypt in memory without writing a single plaintext byte to host storage.
Enterprise customers deploy vendor applications into their private clouds without exposing AWS Access Keys, Secret Keys, or root credentials.
Customer opens a signed activation URL issued by the Vendor containing cryptographically bound license permissions.
Customer launches an AWS CloudFormation stack creating a scoped delegation role (namespace restricted to vastarfort-c*).
Hub triggers pinned change-sets to provision the isolated TEE instance in the customer's private VPC via outbound pull.
Node proves genuine hardware (/dev/nsm, /dev/sev-guest), Hub releases 3-party custody keys, and PAR executes in protected RAM.
VastarFort completely eliminates prolonged enterprise security review cycles through hardware-isolated physical boundaries.
Customer records, health data, and financial transactions process strictly inside customer private enclaves. Vendors cannot inspect customer data, and no plaintext ever leaves local memory.
Release of Content Encryption Keys (CEK) strictly requires mathematical consensus across three decoupled keyholders (Vendor, Customer, Vastar Platform) via HPKE RFC 9180. Zero backdoor channels.
Production verifiers reject synthetic evidence, debug modes, or counterfeit certificates without authentic silicon processor roots (AMD KDS, AWS Nitro Root CA, Intel PCCS).
