Neo4j Aura supports TLS version 1.2 and above (1.2 and 1.3). Note that for TLS v1.2 in order to comply with the best security practices some cipher suites have been disabled due to their weakness. For further details please see the list of supported cipher suites.
TLS versions earlier than 1.2 are deprecated and we strongly encourage you to upgrade to TLS 1.3 where possible.
Neo4j Aura does not support TLS 1.1 nor TLS 1.0
