Live monitoring, syncs to a domain to flag any changes made to your web assets
Frontends are a major attack surface, especially in Web3, where a compromised dApp can lead to asset theft. DNS hijacking and unauthorized JavaScript changes are common tactics used to take over or silently modify user-facing code.
Harmony monitors your domain’s DNS records and deployed JavaScript files. It alerts you when DNS entries are altered or when unexpected script modifications appear in production, whether injected code, swapped libraries, or stealthy updates.


Harmony protects your web app from DNS hijacking, spoofing, and silent frontend takeovers by monitoring your DNS records and deployed JavaScript files for unauthorized changes.
