ValidatorNode is highly secure. We deploy advanced layered Security protection to keep validator infrastructure online that ensures uninterrupted operations at full capacity even when it is a target of DDOS attacks.
Our security setup consists of our validator node contained in a VPC with multiple internet-facing Sentry nodes. We employ redundant server architecture to insure against failures of any server in our network. Firewall rules are maintained within a hardware/software firewall structure. We have both software/hardware wallets utilized to secure our network wallets/keys.
To mitigate against downtime, maintenance is performed using hot-swapping techniques ensuring 99.99% uptime for our network.
