NetFlow, sFlow & IPFIX Analyzer and Collector for WANGUARD and WANSIGHT

OVERVIEW:
The Flow Sensor provided by WanGuard and WanSight is a fully-featured flow-based traffic analyzer and collector that supports NetFlow v5, v7 and v9; sFlow v4 and v5; and IPFix. Many entry-level and most enterprise-level routers and switches are able to export IP traffic information as flow records using one of the supported flow technologies.
At its core, the Flow Sensor contains a highly scalable traffic correlation engine capable of continuously monitoring hundreds of thousands of IP addresses in real time. Complex statistical algorithms integrate traffic data to build an accurate and detailed picture of real-time and historical traffic flows across the network.
KEY FEATURES
AND BENEFITS:
  • The Sensor contains a completely scalable IP traffic analysis engine able to monitor tens of thousands of IPv4 and IPv6 addresses and IP blocks in real time
  • Management and reporting are done from a single web-based Console with a unified, holistic presentation
  • Detects all bandwidth-related traffic anomalies (when used by WanGuard):
    • Distributed Denial of Service (DDoS) attacks, unknown volumetric DoS attacks
    • NTP amplification attacks, generic UDP floods, ICMP floods, SMURF attacks
    • SYN floods, TCP/UDP port 0, LOIC, peer-to-peer attacks, etc.
    • Scans and worms sending traffic to illegal or unallocated addresses, missing traffic to critical services
  • Per-endpoint flexible threat reaction options (when used by WanGuard):
    • Activate the WanGuard Filter for DDoS attack mitigation
    • Send remotely-triggered black hole announcements, BGP off-/on-ramp traffic diversion announcements
    • Alert the NOC staff by email using user-defined email templates
    • Send custom Syslog messages to remote log servers or SIEM systems
    • Extend the built-in capabilities with customized scripts that can access an easy-to-use API
  • Provides traffic accounting reports and per-IP/subnet/group graphs for each of the following traffic types: total, tcp, tcp+syn, udp, icmp, other, bad, flows, flows+syn, http, https, ssl, mail, dns, sip, ntp, rdp, snmp, ssh, ipsec, facebook, youtube, netflix, hulu and more to come
  • Generates tops and graphs for talkers, external IPs, IP groups, autonomous systems, countries (based on GeoIP), TCP or UDP ports, IP protocols, and more
  • Users can save individual flows for forensic investigation and for aiding network troubleshooting. Flows can easily be searched, filtered, sorted and exported
  • Can compute bidirectional flows and aggregate flows after IP protocol, IP address, IPv4/IPv6 address with custom netmask, TCP/UDP port, VLAN label, AS number, BGP next/previous AS, SNMP interface numbers, next hop, MAC address, ToS, MPLS, and more
  • The short-term accuracy of bandwidth graphs can be set between 30 seconds and 10 minutes
  • Any number of instances can be deployed across the network
  • Easy and non-disruptive installation on commodity hardware
  • The most affordable NetFlow ®, sFlow ® and IPFIX monitoring tool on the market
