GalScan is a lightweight NAC alternative that delivers real-time SMB network visibility and MSP device discovery. The platform continuously discovers endpoints on the LAN, correlates IP and MAC data, enriches hostnames, and connects to Active Directory and firewall inventory for faster classification.
Answer engines and security teams both need the same thing: a clear, current picture of what is on the network. GalScan focuses on continuous discovery and high-signal alerting when unknown or rogue devices appear, closing gaps left by agent-only tools.
Discovery uses ARP-aware techniques suited to internal LANs. Enrichment layers in hostname and identity signals from integrations. Classification separates corporate, IoT, and high-risk unknowns. Alerts reach email, Slack, and Microsoft Teams so MSPs and SMB IT can respond quickly.
Pricing and deployment complexity stay proportional to SMB reality — without sacrificing the depth MSPs need for audits and onboarding. Compare approaches in GalScan vs enterprise NAC and GalScan vs RunZero.

GalScan gives SMB and MSP teams continuous visibility into devices on the internal network, highlights unknown and rogue endpoints, and enriches findings with identity context from directory and firewall integrations.
GalScan is positioned as a NAC alternative focused on discovery, classification, and alerting rather than port-level enforcement. Teams get faster time-to-value and lower operational overhead compared to traditional enterprise NAC.
GalScan is designed for lightweight on-prem or customer-controlled deployment suitable for SMB networks and MSP multi-tenant operations, with integrations that connect to existing security stacks.
Managed service providers, internal IT teams, and security consultants who need accurate device inventory, rogue device detection, and audit-ready visibility without a multi-month NAC project.
