About Us

We Think in Packets!

TeraPackets has formed a partnership with CyberRatings.org (formally NSS Labs).

Terapackets, based in Austin, TX, provides vendor-neutral, rigorously proven testing tools to leading equipment manufacturers and testing organizations. We "think in packets" and partner with leading experts to provide advanced packet testing, analysis and other continuous validation offerings. Rapid completion time, modern evasions and the ability to run malware files over multiple transports are some of our differentiating qualities.

TeraPackets is being used in the Cloud Network Firewall test currently underway. The testing technology is also used in testing Software Defined Wide Area Networks (SD-WAN), Enterprise Firewall (formerly referred to Next Generation Firewall - NGFW), and Intrusion Prevention and Detection Systems (IPS / IDS).

TPR-1000 Packet Replayer tool will be used in upcoming Cloud Network Firewall Test.
