Instead, many threats operate quietly after initial compromise, communicating with external servers to receive commands, exfiltrate data, or download additional components. This behaviour often includes: - Repeated connections to known malicious infrastructure - Suspicious command-and-control (C2) communication patterns - Abnormal outbound traffic from devices that should be quiet - Connections to newly registered or high-risk domains Traditional antivirus tools may miss these activities, especially on devices that cannot run endpoint security software. --- ## How Firegate detects malicious behaviour on the network Firegate operates at the **network level**, positioned between your modem and router. All traffic entering or leaving your network passes through it. Rather than scanning files on individual devices, Firegate focuses on **how devices behave on the network**. It evaluates traffic patterns, destinations, and connection characteristics in real time. Firegate uses: - Behaviour-based network inspection - Reputation and threat-intelligence rules - Protocol and traffic pattern analysis When traffic matches known malicious behaviour — such as malware calling home to external servers — Firegate blocks the connection immediately. --- ## Blocking threats before damage occurs By stopping malicious communication early, Firegate can: - Prevent malware from receiving commands - Block data exfiltration attempts - Stop secondary payload downloads - Isolate compromised devices from hostile infrastructure This approach reduces the impact of infections, even when the initial compromise happens elsewhere. Blocking occurs **before traffic reaches its destination**, limiting what malware can do on the network. --- ## Protection for devices that can’t protect themselves Many devices on modern networks cannot run antivirus or endpoint protection, including: - Smart TVs and streaming devices - IoT and smart home equipment - Gaming consoles - Embedded systems Firegate protects these devices automatically, because detection happens at the network edge rather than on the device itself. No software installation is required, and no device-specific configuration is needed. --- ## Local detection, private by design All inspection and detection happens **locally** on the Firegate device. - No traffic is sent to the cloud - No packet data is uploaded for analysis - No behaviour profiles are shared externally - Logs remain on the device Firegate receives rule updates to improve detection accuracy, but your network activity never leaves your control. --- ## A complementary layer of defence Network-level malware behaviour detection does not replace endpoint security where it exists. Instead, it provides an additional layer of protection that: - Covers all devices equally - Detects threats based on behaviour, not files - Works continuously in the background This layered approach improves overall network security without increasing complexity. --- ## The result Firegate helps identify and block malicious activity by watching how devices communicate — not by invading privacy or relying on cloud analysis. Suspicious behaviour is stopped early, threats are contained, and your network remains protected quietly and automatically.
