Statseeker is a powerful network performance monitor solution. It's fast, scalable, and cost-effective. Statseeker requires only one server or virtual machine to be up and running in minutes. It can also discover your entire network in under an hour without any significant impact on your bandwidth availability. It can monitor networks of all sizes, polling upto one million interfaces every sixty second, and collecting network data like SNMP, ping, NetFlow (sFlow, and J-Flow), sylog and trap messages, SDN configuration, and health metrics. Statseeker performance data are never averaged or rolled up. This eliminates the guesswork when it comes to identifying over- and underestimated infrastructure, root cause analysis, capacity planning, and other tasks. Statseeker's complete data retention means the in-built analytic engine can accurately detect anomalies in performance and forecast network behaviour months in advance. This allows network admins to plan and perform cost-effective, preventative maintenance, instead of fire-fighting problems as they occur. Statseeker's dashboards and out-of-the box reports allow you to troubleshoot and fix problems in your network before users are aware.

SuperOps is the AI-native unified platform for modern MSPs and internal IT teams. It replaces the typical four-to-six-tool IT operations stack - PSA, RMM, helpdesk, MDM, asset tracking, network monitoring, patch management and IT documentation - with a single, built-as-one platform on a shared data layer. That architectural choice is what makes the rest of the platform work, particularly its agentic AI. Monica AI, SuperOps' intelligence layer, was designed alongside the platform from day one. It triages tickets, surfaces patch and CVE risks, drafts worklogs, suggests knowledge base articles, and increasingly handles fully autonomous workflows for routine work. SuperOps supports Windows, macOS, Linux, iOS, iPadOS and Android, integrates with the IT and MSP ecosystem (Slack, Teams, Azure AD, Okta, QuickBooks, Xero, Bitdefender, SentinelOne and more), and bundles Splashtop and ISL Online remote access free. Transparent pricing, fast deployment, founder-led product investment.
