What we do

Connectivity, transport, delivery.

Three core capabilities, delivered through a single managed platform and a single point of contact.

Managed routing

Dedicated BGP capacity across IS-RNET peering points with traffic engineering, anycast endpoints and DDoS scrubbing built in.

Encrypted transport

Per-tenant tunnels using modern AEAD ciphers (ChaCha20-Poly1305, AES-128-GCM) with TLS 1.3 and forward secrecy across every hop.

Secure file delivery

Customer-to-customer transfer of arbitrarily large files through dedicated delivery endpoints. Up to 8 Gbit/s aggregate per tenant.

How clients use ISR

A few representative use cases.

Media & post-production

Studios exchanging multi-terabyte rushes between offices in Berlin, Amsterdam and Bucharest without dropping into public cloud egress.

Delivery Transport

Regulated backups

Nightly off-site snapshots from European data centres to redundant storage targets, with encrypted-in-flight and at-rest guarantees.

Delivery

Research grids

Universities replicating instrument datasets between national HPC facilities over our dedicated 100G fibre paths.

Routing

SaaS edge

European-only edge presence for SaaS vendors who need GDPR-compliant data planes and predictable latency to end users.
