Security

# GPU cloud security posture, stated precisely

No vague "bank-grade" claims: this page lists exactly how tenancy, data, network and accounts are protected — and what we deliberately do not collect, which is most of what could leak.

## Workload isolation

### Dedicated silicon

A rented GPU is passed through whole — no MIG slices, no time-sharing, no co-tenants on the die. CPU cores, RAM and disk quotas are reserved, not oversubscribed.

### Container hardening

Non-privileged containers under a hardened runtime: user namespaces, seccomp and cgroup walls, read-only host surfaces. Your image's processes see your instance and nothing else.

### VM boundary on demand

[Full VMs](https://powergpu.ai/products/vms) add KVM hardware virtualisation with VFIO passthrough — kernel-level isolation for compliance-sensitive workloads, at the same price sheet.

## Data protection

- **At rest** — instance disks and volumes encrypted (AES-256-XTS) with per-resource keys; destroy = key discard = cryptographic erasure.
- **In transit** — TLS 1.2+ on the console, API and every HTTP-exposed port; instance-to-instance traffic stays on the private fabric per region.
- **Secrets** — deploy-time env vars stored encrypted, masked in logs and UI; registry credentials likewise.
- **No sneak backups** — we never snapshot customer disks on our own initiative; what you do not snapshot does not exist twice.

## Account security

- Passwords hashed with **Argon2id**; sessions are httpOnly, SameSite, server-revocable.
- API keys stored as SHA-256 hashes, shown once, revocable in seconds — [key docs](https://powergpu.ai/docs/api-keys).
- Password change signs out every other session; bot traffic is filtered without fingerprinting humans.

## Facilities

Every machine lives in an established colocation facility — never residential hosts, never "a rig in a spare room":

- Tier-III (or equivalent) design: redundant power, cooling and carriers;
- ISO 27001 / SOC 2 attested operations, 24/7 physical access control;
- per-site compliance documentation available under NDA for [enterprise](https://powergpu.ai/enterprise) reservations.

## What we do not collect

The cheapest data breach is the one that cannot happen:

- No IP address retention — not in logs, not in the database;
- no payment PII — crypto settlement carries no card, name or address;
- no third-party trackers, no analytics scripts, no ad pixels — check the page source;
- no sale or sharing of usage data, full stop — [policy](https://powergpu.ai/legal/privacy).

## Disclosure & questions

Vulnerability reports: console ticket titled **Security** — routed straight to engineers, answered within 24 h, rewarded when it is real.

**Is my workload isolated from other customers?**

Yes — GPUs are dedicated (no MIG sharing, no time-slicing), containers run under hardened runtimes with their own namespaces and cgroups, and VMs add full KVM hardware virtualisation with VFIO GPU passthrough. Reserved capacity is single-tenant down to the chassis.

**What happens to my data when I destroy an instance?**

The disk is cryptographically erased: instance disks are encrypted at rest with per-instance keys, and destroy discards the key before the blocks are recycled. Volumes follow the same model when deleted.

**How do I report a vulnerability?**

Open a console ticket titled "Security" (any account, free) — it routes to the security engineers directly, first response inside 24 h. Good-faith research on your own resources is explicitly welcomed in our acceptable use policy; bounties are paid in crypto, naturally.
