Observer GigaStor

Enable end-user experience scoring with the best packet capture, analysis, and storage solution in the industry - empowering IT teams with in-depth network conversation details for troubleshooting, performance optimization, and security investigations.



GigaStor serves as the source of packet insights while also storing them for back-in-time access for Observer 3D. Using these packet insights, Observer Apex generates end-user experience scores for every network conversation, providing critical individual and enterprise-wide visibility into IT service health and fast troubleshooting when problems arise.


The undisputed leader in back-in-time analysis, GigaStor eliminates the time-consuming and potentially inaccurate task of recreating problems for troubleshooting and investigating security issues. Just hit rewind to go back in time and review past network activity. Navigate to the exact moment of the service anomaly to see detailed, packet-level views before, during, and after the occurrence.

Eliminate unnecessary finger pointing between Netops, and SecOps and DevOps with fast and accurate root cause identification. Speed resolution of any application, network, or UC issue while using the security forensics capabilities of GigaStor to identify whether a breach has occurred and what resources have been compromised.

GigaStor offers the following features and benefits:

  • Now available in two virtual versions to maintain visibility in all hybrid IT/cloud hosting environments—GigaStor Cloud Edition (GCE) for AWS environments and GigaStor Software Edition (GSE)

  • Independently validated line-rate capture performance at 60 Gbps with support for 100 Gb networks; accelerates service anomaly resolution and security investigations

  • Back-in-time functionality means never having to wait for a service anomaly to repeat before identifying and putting resolution measures into place.

  • Scalable to more than a petabyte of storage capacity enables extended visibility into past service delivery health; AES-256 data-at-rest encryption ensures regulatory data privacy compliance

  • Expert analytics offers detailed network and application intelligence including deep-packet inspection; ideal for in-depth transaction-level awareness into service and potential security issues

  • Fault-tolerant custom design supports five years of uninterrupted, 100 percent duty-cycle capture without dropping a single packet

Its flexibility and storage capacity made Observer GigaStor Portable the logical choice on which to standardize our network practice.
