Scans the network and identifies vulnerabilities on each machine
Nmap is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices. The tool's most valuable feature is its vulnerability scanning. It allows us to scan a specific range of IP addresses and discover devices within that range. This makes it easy to identify devices and view their details. Port scanning is crucial for network management tasks. It helps us identify vulnerabilities by finding open ports that may be unused or misconfigured. This tool makes it easy to detect such issues. The OS detection feature is great. Unlike other tools, Nmap provides accurate information about asset vulnerabilities, helping us easily detect and address them. Using Nmap provides value to the company, especially during compliance audits. It helps generate reports on assets, updates on workstations, and insights into network activities and potential attacks. Additionally, Nmap detects vulnerabilities and provides port details, allowing us to close unused ports on the client machines.

Excellent monitoring and troubleshooting capabilities while identifying exact issue locations
When I first started using ThousandEyes, I found it challenging to extract useful information due to the numerous options available. I needed some training to effectively troubleshoot. More detailed documentation explaining the metrics and the testing mechanisms would be helpful. The information is there, but understanding exactly what ThousandEyes is testing to make its conclusions can be obscure.
