Pattern matching

As new network attack vectors emerge and network traffic volume increases, the need to monitor traffic at high rates is ever increasing. Pattern matching is another feature of APCON’s IntellaView and IntellaFlex HyperEngines that allows SecOps and NetOps teams to match packet contents and filter for specific traffic. This feature allows you to search on individual packets or sessions to identify data based on patterns in any part of the packet payload.

APCON’s pattern matching uses regular expressions (regexs) to match packet contents in near real time.

React intelligently to identified traffic patterns

Today’s network security monitoring tools can benefit from pattern matching to identify potentially dangerous traffic. Using our deep packet inspection technology (DPI), the contents of packets can be matched against patterns of known traffic to identify content, including attack-carrying packets, that can then be forwarded accordingly. APCON’s pattern matching uses regular expressions (regexs) to match packet contents in near real time.

There are many possible actions you can apply on pattern matches, including:

  • None: useful for getting stats or insights into the traffic
  • Mask: swap out the text that matches the regex with a user-specified character
  • Pass: pass packets that match the regex
  • Drop: drop packets that match the regex
  • Session pass: pass all packets in the flow when a packet matches the regex
  • Session drop: drop all packets in the flow when a packet matches the regex


  • Six different actions that can be applied to matching packets

  • Filter traffic on individual packets

  • Filter traffic on sessions


  • Ensure HIPPA & PCI DSS compliance

  • Enable more efficient tool usage

  • Mask personally identifiable information (PII)

  • Malicious content and intrusion detection
