Your network has a normal.
We learn it.
NetSentra is a network first security platform for regulated small businesses. We use professionally deployed edge sensors to learn normal office behaviour, detect suspicious changes, and turn network signals into explainable, human reviewed alerts.
Three things have shifted at once.
They all point in the same direction: the moment for network security to reach small regulated businesses is now.
Attackers have moved downmarket
Ransomware groups now actively target small clinics, brokerages, and law firms. They are soft targets, they hold valuable data, and they tend to pay quickly to avoid a shutdown.
Regulators are tightening
PHIPA, the Law Society of Ontario, FSRA, and CIRO are moving toward formal cybersecurity expectations. Breach reporting timelines are shortening. Evidence requirements are increasing.
Cyber insurance has changed
Insurers now require demonstrable controls before they bind a policy. Businesses that cannot produce evidence of monitoring are seeing premiums double or coverage refused outright.
A clinic ransomware event in Ontario now routinely produces six-figure recovery costs, mandatory patient notification, regulator scrutiny, and weeks of lost billing. Doing nothing is the expensive option.
Network visibility built for small offices.
Small businesses often hold regulated client data without a security team, a SIEM, or analysts watching their environment. NetSentra closes that gap with a network-first security platform built for small offices, clinics, law firms, brokerages, and advisory practices.
Deploy edge sensor
A professionally deployed monitoring appliance sits beside the switch on a mirror port, off the data path entirely. It sees a copy of your traffic, never the traffic itself. No inbound listeners. If it ever fails, internet service continues normally.
Learn each business
Over the first weeks, the platform builds a behavioural baseline for that specific office: device activity, communication patterns, timing, destinations. Every business has its own normal.
Score and route alerts
Suspicious deviations are enriched, scored on a five-tier severity ladder, and routed appropriately. Critical events page a security engineer immediately. Lower-severity activity rolls into a weekly digest.
Human-reviewed escalation
High-risk decisions are reviewed by a human before client escalation or disruptive response. Every alert is traceable to a statistical rule or signature. No black-box AI.
Where the sensor actually sits
Most small offices run one flat network: every device can reach every other one, so anything that gets in can go anywhere. The comparison below shows that network, and the same office after a full NetSentra deployment. Traffic separated by purpose, with a passive sensor on a mirror port beside the switch. It sees everything and sits in nobody's path.
Internet connects to a gateway and firewall, then a PoE switch. Endpoints are separated into business, cameras and devices, guest, and management segments. A passive NetSentra sensor sits beside the switch on a mirror port and reports to a secure cloud. The comparison view shows the same devices on one flat network.
Built for regulated Ontario businesses.
NetSentra is built for small regulated businesses that hold sensitive client data without a security team to protect it. Healthcare clinics, law firms, insurance brokerages, and financial advisory practices. Your clients trust you with their most sensitive information, and that makes you a target.
Medical, dental and allied health
Clinics handling PHIPA-regulated patient records, OHIP numbers, and billing data under IPC oversight.
Law firms and solo practices
Solo and small firm practices with privileged client communications, trust account records, and case files.
Brokerages
Brokerages handling client policies, claim records, and identity and banking information.
Independent advisors
Advisors holding KYC documents, trade history, and portfolio data under securities oversight.
What makes this different.
Built for businesses without a security team. The tools available to small regulated businesses were either built for enterprises with analysts to run them, or too generic to meet regulatory expectations. NetSentra is neither.
The missing network layer
Most security products focus on endpoints or cloud accounts. NetSentra watches the network layer, where printers, cameras, phones, and unmanaged devices reveal behaviour that endpoint tools cannot fully see.
Per-client behavioural baselines
Every office has its own rhythm. NetSentra builds a baseline of normal behaviour for each client individually, then surfaces suspicious deviations that signature-only tools miss.
Explainable detection, no black-box AI
When something is flagged, the reasoning can be shown: statistical deviation from your baseline, a known-bad destination, an unusual fingerprint. No opaque AI claims. That matters to regulators, auditors, and you.
Canadian and regulator-aware
Designed for Canadian data residency and regulator-aware retention. PHIPA, Law Society of Ontario, FSRA, and CIRO expectations inform how we design the service. They are not footnotes.
Human-reviewed on high-risk decisions
High-risk alerts are reviewed before client escalation or disruptive response. That matters when a regulator, insurer, or business owner asks how a security decision was made.
Works alongside your IT provider
NetSentra is not a replacement for your existing IT setup. The sensor sits beside the network. We coordinate with your IT provider rather than competing with them.
