Internet-Security.com TCP port 7473 details

Neo4j graph database uses TCP port 7473 for HTTPS access to its web interface and REST API (with 7474 for HTTP and 7687 for the Bolt protocol), default in Neo4j 2.x–3.x and commonly used/retained in on‑prem deployments of later versions when HTTPS is enabled.
Official Neo4j server packages and Docker images expose 7473/tcp as the secure Browser/REST endpoint, and many enterprise installations front this port behind a reverse proxy.
Security note: attackers scan 7473/7474 for exposed Neo4j instances to try default credentials or no-auth setups to read/modify data; misconfigured plugins like APOC have historically enabled SSRF-like abuse via HTTP calls through the database.
