An incident reported at a subterranean site with zero signal, still lands in seconds.
Our client, a UK-based leading security software company, builds the incident management and resilience platform trusted by security and facilities teams across some of the world's most complex buildings. XFactr engineered the platform's field mobile apps for incident reporting and patrol management, the mobile core that lets guards log incidents, run patrols, and trigger emergency alerts, online or off.
Delivered for a UK-based leading security software company · Android, iOS, backend & cloud · In production today
Built for guards who work where the network doesn't reach
Our client serves security and FM providers, real estate portfolios, and critical infrastructure operators. The field apps needed to work in basements, plant rooms, and dead zones just as reliably as they work at street level. Here's how the engagement was structured, from first line of code to production rollout.
Embedded T&M Engineering
Mobile, backend, and QA engineers joined the client's delivery cadence, spanning our full stack development and quality engineering disciplines.
Full-Ownership Build
XFactr took end-to-end ownership of the incident reporting and patrol management apps.
Architecture Proof of Concept
Offline sync, battery-aware location tracking, and low-latency SOS alerting were each proven out before being hardened for enterprise scale.
Production Deployment
Live on Android and iOS today, backed by cloud infrastructure built for enterprise-grade security.
A UK security software leader: risk, resilience and incident management, made operational
Our client is a UK-based leading security software company whose platform is used by security and facilities teams at organizations spanning commercial real estate, retail, critical infrastructure and other high-security environments. It runs on an enterprise-grade cloud foundation. This kind of high-trust, safety-critical software is exactly where our enterprise platform engineering earns its keep.
System architecture, end to end
The platform runs as a layered system: native mobile clients, a secure API layer, backend services, data and media storage, and real-time alerting. Every layer was built to keep working when the network doesn't.
Nine modules, one field-ready system
Each module was built to work independently and together, from sign-in to compliance reporting.
Authentication & Role Management
Secure enterprise sign-in with SSO and role-based access control for strict data segregation.
Incident Reporting & Logging
Captures photos, video, audio notes, and location to log hazards, security breaches, and maintenance issues.
Patrol & Checkpoint Management
NFC tag scanning, QR verification, and GPS geofencing validate patrol routes and monitor guard tours in real time.
Task & Workflow Management
Automates task assignment, SOPs, safety checklists, and dynamic escalation flows.
Real-Time GPS & Geofencing
Tracks guard positions to optimize dispatch response and support lone-worker safety.
Panic & SOS Alerts
Immediate emergency triggers send the guard's location to central control rooms for rapid dispatch.
Offline Operations Engine
Stores incident submissions, checkpoint logs, and high-resolution media on the device, syncing automatically once the network returns.
Analytics & Compliance Reporting
Generates compliance audits, incident pattern analytics, response-time metrics, and PDF/CSV exports.
Settings & Device Management
Configures location-tracking frequency, battery-saver profiles, notification thresholds, and offline sync behaviour.
What made this genuinely difficult
Building for guards in basements, remote sites, and long shifts surfaces problems most consumer apps never face.
| Challenge | Description | Solution |
|---|---|---|
| Offline Synchronization | Field personnel operating in subterranean, remote, or poor network coverage areas. | On-device data storage with duplicate-safe sync queues and automatic background retry. |
| Battery Optimization | Continuous GPS tracking during extended shifts severely depletes battery life. | Motion-aware dynamic location intervals, balancing update frequency between stationary and active states. |
| Data Security & Integrity | Guard logs and incident reports must remain tamper-proof for legal compliance. | Encryption on the device and in transit, with integrity checks on captured media. |
| Low-Latency SOS | Critical emergency alerts demand immediate delivery to security control desks. | Real-time alerting backed by high-priority push notifications with multi-channel fallback. |
| Resource Optimization | High-resolution image and video uploads exhaust cellular data quotas during shifts. | On-device media compression, adaptive transcoding, and throttled background uploads. |
Mobile & Communication
Backend, Data & Cloud
This is full stack development, API & microservices architecture, and cloud & data security working as one discipline, not three separate handoffs.
What XFactr delivered
A production-grade mobile platform that security teams rely on every shift, in every building, with or without a signal.

Long-term partnerships, not one-off projects
This client joins a small, deliberately chosen list of long-term XFactr partners, the same delivery model behind our work with Kongsberg Digital (now Falkor), Schneider Electric, and WESCO.
