Built for SMEs — not adapted for them.
Enterprise-grade managed firewall for small and medium businesses. Block phishing, ransomware, botnets and C2 in real time — fully managed by the OneFirewall team, at SME-compatible cost.
SMEs are primary targets, with the fewest defences
The spread of cloud, remote working, and mobile devices has expanded the attack surface beyond what legacy firewalls can handle. Phishing, ransomware, advanced malware, and network intrusions increasingly target SMEs — exploiting their limited IT resources and lack of structured defences.
- Intelligent hardware appliance — analyses and blocks traffic in real time
- Fully managed by OneFirewall: configuration, updates, monitoring — all handled
- Proactively blocks threats before they reach corporate devices
- Integrates alliance intelligence from ministries, telcos, banks, and critical infrastructure operators
- Scalable from a single office to multi-site distributed networks
The same protection used by strategic organisations
A traditional firewall sees what is passing but doesn't know how to interpret the context. OneDevice integrates OneFirewall's global threat intelligence, bringing enterprise-grade protection into SMBs.
Not Just Public Feeds
IoCs from ministries, telcos, banks and critical infrastructure operators — not just public feeds.
Shared Instantly
Threats detected in highly sensitive environments are immediately shared to all OneDevice installations.
STIX/TAXII Compatible
Continuous alignment with industry-standard intelligence formats and real-time updates.
A managed security solution, not another appliance to babysit
Proactive Protection
Threats intercepted before they reach corporate devices.
Fully Managed
Configuration, updates and monitoring handled by OneFirewall specialists.
Zero Internal Complexity
No dedicated security staff required to operate it.
Alliance Intelligence
The same threat data protecting governments and banks.

Once powered on and connected, OneDevice listens on UDP 514 for syslog from your network and HTTPS 443 to host its rule engine, while maintaining a continuous connection to the OneFirewall Control Framework for monitoring and updates.
Series, or alongside what you already have
Series
OneDevice sits inline as your firewall: NIC-W faces the internet, NIC-L faces your local network, and NIC-C carries a console connection back to OneFirewall Alliance for monitoring and updates.
Parallel
OneDevice runs alongside an existing firewall — pfSense or any other — receiving its logs over 514/UDP and pushing rule updates back over 443/HTTPS, so you keep your current firewall and add automated enforcement on top.
