IT teams, MSPs, and network engineers use Obkio to gain complete visibility into network performance, whether it's happening in the office, across a hybrid workforce, or in the cloud. Obkio is a Network Performance Monitoring (NPM), observability, and diagnostics platform that works by deploying lightweight monitoring agents at any location, with no special hardware required. These agents continuously measure latency, jitter, packet loss, and bandwidth, while running Visual Traceroutes to map performance across the full network path. The platform covers SD-WAN, MPLS, and VoIP/UC monitoring, along with visibility into multi-site and distributed networks. Application performance monitoring (APM) rounds out the picture with HTTP, Web, and Teams-based synthetic tests. A standout feature, Obkio Insight, automates root-cause diagnostics, quickly showing whether a problem sits within the internal network, with an ISP, or with a third-party provider, backed by concrete performance data. Because it deploys in minutes, Obkio gives teams fast answers instead of raw data to sift through. The result: less time troubleshooting, stronger SLA validation, and clear proof of whether the network performance they're paying for matches what they're actually getting.

See exactly who's calling, who's answering, and how your phone system is performing — without wrestling with raw CDRs or clunky built-in tools. VoIP Detective turns the call data from Cisco CallManager (CUCM), Cisco CUBE, Webex Calling, and Microsoft Teams into clear, searchable reports that anyone on your team can use. Because it installs as a virtual machine inside your own environment, your call records stay on your infrastructure — nothing is shipped off to a vendor cloud. Most teams have it deployed and pulling reports within half an hour. Managers can run their own team and call-activity reports without help from IT, while administrators get the depth they need: inbound, outbound, and hunt-group reporting (including who answered and which calls were abandoned), busy-hour analysis for staffing, network-quality troubleshooting by jitter, latency, and packet loss, gateway capacity planning, and endpoint utilization to reclaim unused licenses. The free Lite edition never expires and places no limit on users or devices. VoIP Detective Pro unlocks unlimited data retention, scheduled report delivery, emergency-call alerts, GDPR phone-number masking, CUBE analytics, and a live UCCX wallboard — all at a single flat yearly rate that doesn't change with the size of your deployment.

StreamGroomers oversee and manage the flow of traffic within Wide Area Networks (WAN). They function seamlessly, regardless of the specific network framework, positioned between the LAN and WAN access router, with control facilitated through an out-of-band management setup. To guarantee uninterrupted service, they employ high-availability architectures. StreamGroomers conduct real-time analysis of network traffic at wire speed, gathering extensive measurements and packet data from various points throughout the network. From this information, indicators are generated in real-time to reflect the current state of network performance. The collected data is then consolidated and transmitted to a central repository with minimal impact on network resources, allowing for rapid analysis and troubleshooting, while also maintaining thorough records for forensic purposes. Additionally, the Deep Packet Inspection feature of the StreamGroomer examines Layer 2-7 packet data to accurately identify applications and user sessions based on a predefined catalog of over 400 services, thus enhancing network visibility and control. This capability not only aids in performance monitoring but also supports proactive network management strategies.
