• Configure routing rules to prevent leaking internal project names

Backups and Monitoring

• Automate daily backups and validate them regularly
• Monitor Nexus logs and metrics with external tools like Prometheus

Performance Tuning

• Avoid too many blob stores, use blob store groups
• Keep staging repos in same blob store
• Set blob store quotas and alerts
• Use a test environment for reporting

Security Hardening

• Enable audit logging
• Limit user privileges with roles
• Integrate authentication via LDAP or OAuth
• Check repository health for risks

Integration and Management
