OneSecure — Cybersecurity for Schools & Businesses

Enterprise-grade DNS security made simple for organizations in Denmark, Finland, and Latvia.

Network Security That Protects Every Device

OneSecure provides a plug-and-play hardware appliance — the OneSecure Box — that sits on your network and delivers DNS-based threat protection, ad and tracker blocking, intrusion detection, and real-time monitoring. Every device on your network is automatically protected, from desktops and laptops to IoT devices, printers, and smart displays, without installing software on each one.

Our solution is built for schools, municipalities, healthcare providers, financial institutions, and small-to-medium businesses that need robust cybersecurity without the complexity. OneSecure handles deployment, configuration, and ongoing management so you can focus on your core mission.

Complete Layered Protection

The OneSecure Box blocks malicious domains, phishing attempts, malware callbacks, and unwanted trackers at the DNS level before threats ever reach your devices. For endpoint protection, OneSecure also offers its own managed antivirus solution powered by Bitdefender, covering Windows and macOS. Together, network-level DNS filtering and endpoint antivirus create a comprehensive defense-in-depth security posture.

All protected devices and security events are visible through the OneSecure client portal, where you can view real-time statistics, manage blocklists and whitelists, generate compliance reports, and monitor device health.

Purpose-Built for Schools and Businesses

Schools face unique challenges: protecting students from harmful content, securing dozens of devices across multiple networks, and meeting regulatory requirements. OneSecure solves these with custom filtering rules, per-subnet policies, and NIS2 compliance reporting built right into the platform.

For businesses, OneSecure provides enterprise-grade security without enterprise complexity. Our managed service model means no dedicated IT security staff is required. We handle everything from initial setup to ongoing monitoring and updates, with support available in Denmark, Finland, and Latvia.

How It Works

Getting started takes three simple steps. First, we assess your network security needs during a consultation. Then, we deploy and configure the OneSecure Box on your network with security rules tailored to your organization. Finally, your network is protected around the clock with real-time alerting and ongoing support.
