Nofence: Virtual Fencing with GPS Collars for Cattle, Sheep, and Goats
Nofence is a solar-powered virtual fencing system that replaces posts, wires, and physical fences with GPS collars, progressive audio warning cues, and a mobile app that lets producers draw, adjust, and manage grazing boundaries from their phone. Founded in Norway in 2011 by goat farmer Oscar Hovde, Nofence was the first company to commercialize this technology and now operates across several European countries and the United States, with a direct presence in Norway, the UK, Ireland, and Sweden.
Unlike systems such as Halter, which rely on communication towers installed in the field, Nofence runs on GPS and cellular networks — no base stations or additional infrastructure required. Its proprietary HerdNet technology keeps the herd connected even in areas with limited cellular coverage. The system supports cattle, sheep, and goats, and the company offers dedicated sales and support teams in its active markets.
AgentAya Verdict
Nofence was the first virtual fencing system to reach the market. Its value proposition centers on operational simplicity: a solar-powered collar, an app, and the cellular network. Producers draw grazing boundaries from their phone, and animals learn to respect them within days. After training, 96% of boundary interactions resolve with sound alone.
Nofence’s edge over its competitors comes down to three factors: compatibility with three species (cattle, sheep, and goats), a transparent purchasing model, and comprehensive multilingual support with full English coverage. The warranty and the included first year of subscription lower the barrier to entry for operations looking to test the technology without a long-term commitment. On the flip side, the platform focuses squarely on virtual fencing and movement monitoring — it does not currently offer features like automated heat detection or satellite-based pasture coverage estimation. That said, future updates could change this.

AgentAya Overall Score: 4/5 ⭐⭐⭐⭐
Ideal For
- Beef cattle operations that need to bring rough, underused, or hard-to-fence ground back into rotation, managing grazing remotely without installing physical infrastructure.
- Sheep and goat operations on hard-to-access terrain, conservation grazing projects, or areas where traditional fencing is impractical or prohibitively expensive.
- Producers who need a system with full English-language support, a regional sales team, and access to financing and grant programs.
- Dairy operations looking to manage dry cows and replacement heifers on rotational grazing without pulling attention away from the milking herd.
- Contract grazing operations (solar farms, golf courses, conservation areas) that need precise documentation through heat maps.
Not Ideal For
- Operations that require advanced pasture analytics (satellite-based coverage estimation, forage availability projections, dry matter allocation per animal) or automated heat detection.
- Operations in areas without cellular coverage where HerdNet cannot maintain herd connectivity.
- Operations with unsupported species: the system only works with cattle, sheep, and goats.
Key Features
- Virtual fencing without infrastructure: producers draw grazing boundaries from the mobile app. The collars guide animals with progressive audio warning cues. If the animal does not stop, a mild electric pulse — roughly half the intensity of a conventional electric fence — is delivered as a last resort. No base stations, no buried cables, no posts.
- Three-species compatibility: cattle (beef and dairy), sheep, and goats. The system adapts to the natural behavior of each species and herd.
- Four grazing patterns: strip (adjusted in minutes from the phone using heat maps), rotational (flexible paddocks with advance planning), extensive (digital control over terrain where traditional fencing cannot reach), and contract (heat map documentation for vegetation management on third-party land).
- Real-time tracking: GPS location for every animal, 24/7. Automatic alerts if an animal crosses a boundary, with exact location for rapid intervention.
- Early health issue detection: continuous movement monitoring identifies unusual activity patterns that deviate from the herd’s normal behavior, functioning as an individual-level early warning system. According to Nofence, this helps reduce veterinary costs and antibiotic use.
- HerdNet: proprietary technology that allows collars to communicate with each other via Bluetooth. If only one collar has cellular coverage, it downloads boundary updates and shares them with the rest. The system coordinates herd transitions by mimicking natural group movement, which also reduces battery consumption on each collar by decreasing how often they need to individually connect to the network.
- Shelter beacons: companion devices that create safe zones within the grazing area and help conserve collar battery.
- Solar-powered collar: designed for field conditions, with improved battery life thanks to the latest product updates.
Beyond fencing: herd visibility and work-life balance
Producers who have spent time with the system consistently highlight one thing: they can see their entire herd around the clock — and that changes how they work day to day.
That constant visibility has a tangible impact on balancing farming and personal life. The app cuts down on field visits and turns hours of fence work into minutes on the phone.
For beef operations, Nofence brings land back into use where traditional fencing was never an option. For dairy operations, it frees up time producers would otherwise spend managing groups on rotational grazing. And for contract grazing, it delivers the documentation that this type of service demands.
Data Analytics Features
Nofence does not position itself as an artificial intelligence platform. Instead, the company has built a precision livestock management system grounded in GPS, control algorithms, and advanced communications.
- Each collar operates as a standalone device that interprets the virtual boundary drawn in the app and acts accordingly: it delivers progressive audio warning cues and, only if the animal ignores them, a brief electric pulse. The collar logic is tailored to the natural behavior of livestock.
- HerdNet enables collars to share boundary updates via Bluetooth and coordinate herd transitions in a way that mimics natural group movement — in practice, this works more like advanced automation adapted to livestock than a predictive or generative AI platform.
- Nofence has accumulated over 700 million hours of grazing data, which it uses to improve its products and explore new use cases such as animal behavior analysis, conservation grazing, and wildfire prevention.
- The system compares each animal’s movement data against the herd’s normal behavior to flag deviations that may indicate health issues, enabling early detection at the individual level.
- Grazing heat maps show where animals have spent the most time, helping plan rotations and fine-tune paddock design.
Integrations
The Nofence ecosystem is self-contained: collar, app, and cellular network. There is no documented public API, third-party software integration catalog, or connections to sorting gates or herd management systems.
Data Security and Regulatory Compliance
Nofence processes personal data in compliance with the EU General Data Protection Regulation (GDPR) and the Norwegian Personal Data Act.
- Personal data collected includes name, address, email, phone number, and payment information.
- Nofence uses HubSpot as its customer relationship management system, Google Workspace for day-to-day operations, and Visma and Xero for accounting.
- Accepted payment methods include Stripe, GoCardless, and Vipps (the latter available only in Norway), each of which acts as an independent data controller for payment-related data.
- Personal data is retained for the duration of the active business relationship and, as a rule, deleted one year after it ends.
- Solution Data — which includes sensor data, location, diagnostics, and animal behavior data — is the exclusive property of Nofence, which may use it to improve its products and develop new services.
Recommendation for SMEs: review the privacy policy and the product and subscription terms available in the legal section of the Nofence website. Keep in mind that Solution Data belongs to Nofence, not the subscriber, and that the aggregate liability cap is set at the equivalent of subscription fees over the preceding 12 months.
Language: Customer Support and Interface
The app, website, and documentation are fully available in English and support additional languages. The knowledge hub includes pre-purchase guidance, setup and onboarding guides, and troubleshooting help — all available in English.
- Language of Analytics and Alerts: Nofence does not include a conversational AI assistant or natural language processing features. Alerts and notifications — such as boundary breaches, unusual activity changes, and battery status — are generated automatically from sensor data and delivered through the app.
Mobile Access
The mobile app is the primary management interface, available on iOS and Android.
Core functions include creating and modifying grazing areas on the map, an overview of all the user’s collars, automatic notifications when an animal crosses a boundary, and access to movement data and heat maps.
Support, Onboarding, and Account Management
Nofence provides remote support by email and phone during business hours as part of the subscription, focused on technical assistance for using the solution.
Onboarding is supported through the knowledge hub, which covers everything from first steps (unboxing, charging, fitting the collar) to herd training, with separate guides for cattle and for sheep and goats. Documented topics include how virtual fencing works, animal behavior, cellular coverage and connectivity, shelter beacons, HerdNet, handling facilities, drawing virtual pastures, and why every adult animal in the herd needs a collar (minimum of five adults per herd).
Subscription management and configuration are handled through the account pages on the website.
Ease of Use/UI
The animal training period lasts 5 to 10 days and requires at least 20 positive interactions per animal. The protocol is gradual: animals first wear the collar deactivated to get accustomed to it, then a virtual boundary is activated in a pasture enclosed on three sides by physical fence. In training mode, any movement by the animal away from the boundary immediately stops the sound, reinforcing the association between the cue and the need to change direction.
Once training is complete, day-to-day management is straightforward: the producer adjusts boundaries as conditions change and manages multiple pastures from the phone.
Pricing and Plans
Nofence operates on a hardware purchase plus software subscription model. Collar prices are publicly listed on the company’s website and vary by species (cattle, sheep, or goat).
- Collar (hardware). Each collar includes a five-year warranty and the first year of app access, technical support, and software updates at no additional cost.
- Subscription. Starting in the second year, the producer chooses between a monthly or annual subscription. The subscription covers app access, remote support, and software and firmware updates. It renews automatically for equal periods unless either party provides written notice at least three months in advance. If the prepaid period expires without renewal, the user is automatically moved to a monthly plan billed in arrears. A collar is considered in use (and incurs a charge) if the battery remains inserted for three consecutive days within a month.
- Payment methods. Stripe and GoCardless, among others depending on the jurisdiction.
- Financing. Financing options, cost-share programs, and grants are available to help offset the cost of virtual fencing. In the U.S., federal programs such as NRCS EQIP and state-level incentives support the adoption of innovative grazing technology. In the EU, CAP-linked subsidies (direct payments, eco-schemes, and rural development programs) and regional grant programs may also apply. Nofence’s team can help identify relevant opportunities for each operation.
Case Study
A beef cattle producer manages 45 cows across hillside pastures and leased plots spread several kilometers apart. Some of the grazing land has sat unused for years because the cost of fencing it simply didn’t add up.
After completing herd training in ten days, the daily routine shifts: every morning, the producer checks each animal’s location and status from the app — no need to drive out to the field. When one cow shows unusually low activity two days in a row, a quick inspection reveals early-stage lameness that gets treated before it worsens.
Rotational grazing paddocks are drawn and adjusted straight from the phone. Hillsides that were never fenced are now part of the rotation, and heat maps confirm even utilization across the land. In summer, those same maps double as documentation to support a conservation grazing subsidy application. In areas with patchy coverage, HerdNet keeps the herd synced if at least one collar picks up a signal.
By the end of the season, the producer has cut out kilometers of fence maintenance, brought three new paddocks into use, and built a continuous record of every animal’s location and activity.
