Neon has introduced a new security feature called IP Allow for its Pro Plan customers, enhancing the security of its fully hosted and managed PostgreSQL instances. This feature allows users to restrict access to their database branches by specifying a range of allowed IP addresses, adding an extra layer of protection against unauthorized access and common attack vectors like phishing. The IP Allow feature complements existing security measures, such as requiring passwords with at least 60 bits of entropy, by ensuring that even if attackers obtain valid credentials, they are unable to connect unless they use an IP address on the allowlist. Users can implement this feature through the Neon console, where they can specify the allowed IP addresses, thereby preventing access from any other IPs and ensuring that only trusted sources can connect to their databases.
