A domain is the gateway to your online presence (website) and communications (email). Unauthorised access to this valuable asset could cause unquantifiable damage to your clients, business, and your reputation.
Domain hijacking can significantly harm your business.
A registry lock guards your domain by adding an additional security verification before any changes can be made to the domain.
Not all registries provide a locking service, so Lexsynergy offers a bespoke proprietary Registrar Lock service. This requires an “out-of-band" authorisation process for an update to take effect.
Domain owners can ensure the stability and availability of their domain by implementing a registry lock. It minimises a brands exposure to risk and unauthorised changes that could result in downtime.
A Registry Lock adds additional security protocols.
All critical domain updates are subject to strict verification procedures, ensuring that no amendments can be made without authorised approval. This structured approach reduces the risk of human error, internal misuse or external compromise.
A Registry Lock provides an extra layer of security to a domain, by preventing unapproved DNS modifications, domain transfers or updates.
