No open ports.
No data leakage. No risk.
WAVFlow6 NXT was designed for enterprise IT teams who need to know exactly what is on their network — and what is not. Store-and-forward architecture means no streaming, no open inbound ports, and no third-party data flowing through your infrastructure.
Every streaming service is a live connection to the internet.
Spotify Business, Apple Music, and YouTube Music require a persistent outbound connection to third-party servers. That connection is a data pipe — and your IT team does not control what flows through it.
Open outbound ports
Streaming services require ports 443 and 4070 to remain open at all times — a permanent hole in your perimeter firewall.
Third-party data collection
Spotify and YouTube collect device identifiers, IP addresses, and usage telemetry from every device running their software — including devices on your corporate network.
No offline fallback
When the connection drops, the music stops. Your IT team gets blamed for a business continuity failure they did not cause.
Uncontrolled software updates
Streaming clients update automatically, introducing new code to your managed devices without your approval or testing cycle.
One scheduled sync. Then the internet is done.
WAVFlow6 NXT downloads your approved programme to the local device during a scheduled maintenance window. After that, playback is entirely local. No streaming. No live connection. No exposure.
Scheduled sync window
The NXT device connects outbound during your approved maintenance window — typically 2 AM to 4 AM — to download the next programme cycle.
Local cache playback
All audio plays from the encrypted local cache. No internet connection is required or used during business hours.
Firewall-friendly
Only one outbound destination: WAVFlow servers. Whitelist a single IP range and the device is fully contained within your security policy.
Firewall rule: Allow outbound TCP 443 to sync.wavflow.co during maintenance window only. Block all other outbound traffic from NXT device. No inbound rules required.
Built for IT governance from day one.
Audit trail
Every programme change, sync event, and playback session is logged with timestamp, device ID, and operator. Full chain of custody for compliance reporting.
Encrypted local storage
Audio files are stored in an encrypted container on the NXT device. Content cannot be extracted or played outside the WAVFlow6 environment.
No inbound ports
The NXT device never accepts inbound connections. There is no remote access surface, no SSH, no web interface exposed to the network.
Managed device profile
NXT devices ship with a locked-down OS image. No app store, no browser, no user-installable software. One purpose, one function.
Data residency
All WAVFlow servers are operated from the Philippines. No audio data, device telemetry, or usage logs leave Philippine jurisdiction.
DICT-aligned security posture
Architecture aligns with DICT Cybersecurity Framework guidelines for enterprise IoT devices deployed in commercial environments.
