Nmap and NETSCOUT vSTREAM are both vital in the network operations category, with Nmap focusing on discovery and vSTREAM on performance monitoring. While Nmap leads in cost-effectiveness and simplicity, NETSCOUT vSTREAM has the advantage in providing comprehensive network insights.
Features: Nmap provides host detection, port scanning, and network diagnosis capabilities crucial for security assessments. It is easy to use and perfect for basic diagnosis. NETSCOUT vSTREAM provides real-time application visibility, analytics, and deep insights into network performance, catering to those needing detailed analytics.
Room for Improvement: Nmap could enhance its user interface and documentation for beginners and offer more advanced reporting features. Integrating additional monitoring capabilities would also boost its functionality. NETSCOUT vSTREAM could refine its pricing model, simplify initial deployment to reduce setup time, and enhance its user interface to facilitate easier navigation.
Ease of Deployment and Customer Service: Nmap offers ease of use due to its straightforward and open-source nature, requiring minimal support. Its community resources are plentiful. NETSCOUT vSTREAM involves a more comprehensive setup with strong deployment support and customer service, offering ongoing insights to optimize network performance.
Pricing and ROI: Nmap presents a no-cost solution, making it appealing for basic network discovery. In contrast, NETSCOUT vSTREAM demands higher initial investment but delivers significant ROI through its advanced monitoring and analytics, valuable for organizations that require extensive performance analysis.
The vSTREAM virtual appliance complements existing Adaptive Session Intelligence (ASI)-based instrumentation to provide the same level of visibility within virtualized and cloud infrastructures that is already possible in physical environments. The vSTREAM virtual appliance is ideal for monitoring service-critical traffic running within virtualized or cloud infrastructures, either locally on a host or as an aggregation point for multiple hosts. With complete visibility across physical, virtual and cloud networks, the vSTREAM virtual appliance presents real-time views of end-to-end call trace data and network-wide KPIs, to protect the reliability and availability of networks and application services.
Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
