WanGuard Sensor uses an extremely fast and highly innovative traffic anomaly detection engine that detects volumetric attacks by profiling the on-line behaviour of users and by comparing over 120 live traffic parameters against user-defined thresholds. You can automate reactions to threats using predefined or custom modules that send notification emails, announce prefixes in BGP, generate SNMP traps, modify ACLs, execute your own scripts with access to over 70 operational parameters through an easy-to-use API, etc. DDoS attacks are detected using multi-vendor flow-based technologies, by sniffing IP packets, or through SNMP polling.
WanGuard Filter ensures zero downtime for customers and services during Distributed Denial of Service attacks, without operator intervention. It defends against DDoS attacks by several complementary methods: cleans the malicious traffic on-premise when the upstream links are not congested, null-routes attacked destinations in BGP to prevent bandwidth saturation and the subsequent network outage, notifies the attacker's ISP. Attacks are blocked by applying intelligent, dynamic filtering rules on stateless software or hardware firewalls. Dedicated packet scrubbing servers can be deployed in the main data path, or can perform side-filtering through BGP-based traffic diversion.
WanGuard and WanSight provide full network traffic visibility through distributed Sensors ("probes"), able to analyze IP packets, SNMP data and flow records exported by Cisco NetFlow, Huawei Netstream, Juniper jFlow, cflowd, sFlow and IETF IPFIX. All collected data are accessible in a rich, web-based user interface with custom dashboards, real-time traffic graphs and top listings. You can easily generate complex analytics with aggregated data for hosts, departments, interfaces, applications, autonomous systems, countries, etc. You can view extremely accurate bandwidth graphs for hundreds of thousands of IP addresses, inspect packets and flows, and much more.
The Flow Sensor provided by WanGuard and WanSight is a fully-featured flow analyzer and collector that supports all major flow technologies: NetFlow version 5, 7 and 9; IPFIX; sFlow version 4 and 5. It contains a highly scalable traffic correlation engine capable of continuously monitoring hundreds of thousands of IPv4 and IPv6 addresses and ranges. Flows can be stored for as long as you wish in a compressed binary format. You can generate top listings and almost any other aggregation report you can think of. The extensive flow filtering expression options allow you to quickly query individual flows for ad-hoc forensic investigation.
The Packet Sensor provided by WanGuard and WanSight inspects IP packets by sniffing 10 Gbps port-mirrored or in-line interfaces at wire-speed. It contains a completely scalable IP traffic analysis engine able to monitor, in real time, tens of thousands of IPv4 and IPv6 addresses and ranges. Users can save packet dumps for forensic investigation and aiding network troubleshooting. Packet dumps can be downloaded or viewed online in a Wireshark-like interface that displays detailed layer 7 information and hexadecimal raw and ASCI data for inclusion in regular expressions. Is supports sniffing optimization technologies like PF_RING and Sniffer 10G.
