Disclaimer and Warranty
Last updated: June 2026
What Heron is
Heron is a passive network monitor. It watches DNS traffic on your local
network and shows you what it sees. It does not:
- Block, filter, or modify any traffic
- Act as a firewall or security appliance
- Replace your router or any network equipment
- Detect or prevent malware, intrusions, or cyberattacks
What Heron is not
Heron is not a security product. It does not protect your network. It tells
you what's happening on your network so you can make your own decisions.
If you need a firewall, use a firewall. If you need antivirus, use antivirus.
Heron is an observability tool. It helps you see, not defend.
Warranty
Heron hardware is warranted against defects in materials and workmanship for
1 year from the date of purchase. During that period, Northsline will
repair or replace a defective device at no cost to you.
The software is provided "as is" without warranty of any kind. Northsline does
not guarantee that:
- The software will be error-free or uninterrupted
- Every DNS query will be captured (network conditions vary)
- Device identification will always be accurate (MAC addresses can be spoofed)
- The dashboard will work on every browser or device
Accuracy of information
Heron identifies devices by their MAC address and DNS behavior. This
information comes from your network traffic. Northsline does not guarantee
the accuracy of device names, vendors, or classifications shown in the
dashboard. These are best-effort estimates based on publicly available data.
Limitation of liability
To the maximum extent permitted by law, Northsline is not liable for any
damages arising from the use or inability to use Heron, including but not
limited to:
- Loss of data
- Privacy breaches
- Security incidents on your network
- Business interruption
- Any indirect, special, or consequential damages
If Northsline is found liable despite this disclaimer, total liability is
limited to the amount you paid for the device.
Your responsibility
You are responsible for:
- Configuring your router to use Heron as its DNS server
- Keeping your network secure
- Interpreting the information Heron shows you
- Deciding what action to take based on that information
