List of
Subprocessors

Bunker uses a limited number of subprocessors to deliver its services. Our infrastructure is hosted in France, in our datacenters in western France and on dedicated servers we rent from Scaleway in Paris. Three of these subprocessors (Stripe, Cloudflare, Tailscale) are US companies: we limit their scope to payment, network protection and the managed Zero Trust VPN's fallback relaying alone. Stripe and Cloudflare are governed by Standard Contractual Clauses; the use of Tailscale's relays is not, and we state it as such below.

Subprocessors

Subprocessor Headquarters Processing location Purpose Data processed DPA
Scaleway (Scaleway SAS) France France (Paris) Dedicated server hosting (Elastic Metal) in Paris Data of the managed services hosted on these servers Yes
Stripe (Stripe Inc.) United States United States Payment processing Billing data, payment tokens Yes
Cloudflare (Cloudflare Inc.) United States Global network of points of presence DNS and DDoS protection Visitor IP addresses, HTTP requests Yes
Tailscale (Tailscale Inc.) United States Global relay network, European and outside Europe Relay map and fallback relaying for the managed Zero Trust VPN (Headscale), when no direct connection is possible Encrypted WireGuard traffic, not decryptable by the relay; IP addresses, volumes, timestamps No
Brevo (Brevo SAS) France European Union; sub-processors in the United States and India Transactional quota alert e-mails, to the administrators of customer organizations Recipient's e-mail address, organization name, namespace, quota dimension and percentage No
BetterStack (Better Stack Ltd) Lithuania (EU) European Union Uptime monitoring Public URLs, response times Yes

A European alternative to Cloudflare is being evaluated.

No data processing agreement currently governs the use of Tailscale Inc.'s relays: the managed Zero Trust VPN's fallback uses a public relay map, which Tailscale Inc. maintains. Relayed traffic stays encrypted end to end by WireGuard and cannot be decrypted by a relay, which holds no key; a direct connection uses no relay.

Brevo sends no e-mail yet: the sender stays disabled until Brevo's data processing agreement is signed, with its standard contractual clauses for transfers to its sub-processors outside Europe (Brevo Inc., Cloudflare, Zendesk and Omni in the United States, Brevo CRM Solutions Limited in India).
