Identity and access
SSO, short lived credentials, per environment RBAC and break glass accounts that are logged and alerted on when used.
Security by design
Secure every layer of your blockchain infrastructure
Blockchain security goes far beyond smart contracts. Nuvio secures the infrastructure, networks, identities and operational environments behind critical blockchain systems.
Capabilities
Where we secure your platform
Secrets and keys
Vault or cloud KMS, HSM backed signing keys where it matters, and rotation that runs on a schedule instead of after an incident.
Network segmentation
Private subnets, security groups and Kubernetes network policies, so a compromised pod cannot reach the database or the node hosts.
Edge and DDoS
Cloudflare or provider scrubbing in front of public APIs and RPC endpoints, with WAF rules and per key rate limits at the gateway.
Host and cluster hardening
CIS aligned OS baselines, image scanning, admission policies, SSH behind a bastion or identity aware proxy, patching windows that are actually kept.
Detection and response
Audit logs, Falco or eBPF based runtime detection, alert routing that pages a human, and runbooks written before the first incident.
Backup and recovery
Offsite and immutable copies, restore drills with a measured recovery time, not a retention policy nobody has tested.
Focus
Our security scope
Nuvio focuses on the infrastructure layer of blockchain security rather than smart contract auditing.
