Bandwidth monitoring can help to optimise network performance

Additionally, bandwidth monitoring provides valuable insights into network traffic patterns and usage trends. By analysing bandwidth usage over time, administrators can identify peak usage periods, determine average bandwidth consumption, and forecast future bandwidth requirements. This information is crucial for effective capacity planning and network optimisation. It helps organisations make informed decisions about upgrading their network infrastructure, allocating resources efficiently, and optimising their network design to support business-critical applications.

Furthermore, bandwidth monitoring can help identify potential security threats and network anomalies. Abnormal bandwidth usage or spikes in traffic may indicate malicious activity, such as DDoS attacks or unauthorised data exfiltration. By monitoring bandwidth, administrators can detect such anomalies and take prompt action to mitigate security risks and protect the network.

Fortinet's FortiGate solutions offer comprehensive bandwidth monitoring capabilities. Through the FortiGate dashboard, administrators can add widgets to monitor interface bandwidth usage, both incoming and outgoing, in real time. FortiGate also supports SNMP (Simple Network Management Protocol), which allows for the collection and analysis of detailed interface usage data over time. This information can be visualised using monitoring applications or SNMP servers for deeper insights into network performance.

By leveraging FortiGate's bandwidth monitoring features, network administrators can make data-driven decisions to optimise network performance, allocate resources efficiently, and maintain a secure and reliable network environment for their organisation.

It can help to identify and address security threats

Monitoring bandwidth usage on Fortigate can help identify and address security threats by providing visibility into network activity and enabling the detection of anomalous behaviour. By tracking bandwidth utilisation, administrators can identify spikes or unexpected increases in traffic, which may indicate a potential security breach or malicious activity.

For example, a sudden increase in outgoing traffic could suggest unauthorised data exfiltration, while a spike in incoming traffic might indicate a distributed denial-of-service (DDoS) attack. With real-time bandwidth monitoring, security teams can quickly detect such anomalies and take prompt action to mitigate the threat.

Fortigate's bandwidth monitoring features, such as the ability to view interface bandwidth utilisation from the GUI, provide a comprehensive view of network traffic. This visibility enables administrators to establish a baseline of normal network behaviour and easily identify deviations from this baseline, enhancing their ability to detect and respond to security threats.
