Lightning nodes are equivalent to Bitcoin hot wallets from a security point of view. If an attacker gains access to the server where they run, all funds may be lost. VLS allows the signing to be performed in a secure environment with configurable controls. VLS also opens the path to future multi-sig Lightning support, to improve security further.

The blind signing case has two points of attack - at the node and at the Signer. A blind signer will perform any signing operation the node requests, so a compromised node will still result in loss of funds. And obviously, a compromised signer will also result in loss of funds. This is worse than a monolithic node because funds can be lost if either is compromised. To learn more click here.
