Obkio helps IT teams, MSPs, and network engineers see exactly what's happening across their network, from the office to remote and hybrid workforces to the cloud. As a Network Performance Monitoring (NPM) and observability platform, Obkio uses lightweight software agents (no hardware needed) to continuously monitor latency, jitter, packet loss, and bandwidth while mapping the full network path with Visual Traceroutes. The platform is built to handle the complexity of modern networks, with support for SD-WAN, MPLS, and VoIP/UC monitoring, as well as visibility across multi-site and distributed environments. Application performance monitoring (APM) is also included, covering HTTP, Web, and Teams-based tests. Obkio Insight takes this further with automated diagnostics that pinpoint the root cause of an issue, whether it's internal, an ISP problem, or a third-party service, backed by real performance data instead of guesswork. Obkio is designed for fast deployment and clear results, giving teams the evidence they need to reduce downtime, meet SLAs, and confirm they're getting the network performance they're paying for.

Whether your organization runs Cisco CallManager (CUCM), Cisco CUBE, Webex Calling, Microsoft Teams, or a mix of them, VoIP Detective brings their call records together into one reporting platform you can actually understand. Instead of exporting CDRs into spreadsheets or fighting with native tools, teams get clear reports and dashboards that answer everyday questions in seconds — where calls are going, who's answering, and where quality problems start. It runs as a virtual machine on your own hardware, so sensitive call data stays under your control rather than in a third-party cloud, and a typical install is finished in well under an hour. The platform is designed for everyone who touches the phone system, not just engineers. Department managers pull their own team and activity reports; administrators dig into hunt-group answer detail, abandoned calls, busy-hour staffing trends, jitter/latency/packet-loss issues, gateway capacity, and unused-device cleanup for license recovery. Pricing is refreshingly simple. The Lite edition is genuinely free with no expiration and no cap on users or devices, and Pro is one predictable annual fee — unaffected by headcount or call volume — that adds long-term retention, automated report scheduling, 911 alerting, GDPR masking, CUBE analytics, and a UCCX wallboard.

StreamGroomers play a crucial role in managing and directing traffic within Wide Area Networks (WAN). They operate effectively across various network architectures, situated between the LAN and WAN access router, with their functionality supported by an out-of-band management system. To ensure continuous service delivery, they implement high-availability designs. StreamGroomers perform real-time traffic analysis at wire speed, collecting detailed metrics and packet information from multiple network locations. This data is used to generate real-time indicators that illustrate the current performance status of the network. Subsequently, the gathered information is aggregated and sent to a central repository with minimal strain on network resources, facilitating swift analysis and troubleshooting, while also preserving comprehensive records for forensic analysis. Furthermore, the Deep Packet Inspection capability of the StreamGroomer scrutinizes Layer 2-7 packet data, enabling precise identification of applications and user sessions based on a defined catalog of over 400 services, thereby improving both network visibility and control. This feature not only contributes to effective performance monitoring but also enhances the ability to implement proactive network management strategies, ensuring better overall network reliability. With these advanced functionalities, StreamGroomers significantly bolster the operational efficiency of the networks they oversee.
