Room For Improvement

Nmap requires a GUI, faster scans, enhanced reporting, vulnerability assessments, advanced features, and improved stability for better usability.
ThousandEyes needs enhanced user-friendliness, integration, licensing, and expanded features like analytics, monitoring, and security for improved user experience.
Nmap could potentially become a GUI and provide automatic reports with one-click downloads.
Student at a consultancy with 11-50 employees
Incidents should be alerted on and traced early, before they escalate to full outages.
Software Developer at The Code
I think the pricing, setup cost, and licensing for ThousandEyes are too costly.
R&D at a comms service provider with 51-200 employees
Instead of that, if the platform itself is able to identify the problem and give a suggestion instantly for rectification or correction of the problem, through the necessary approval of the platform owner or the SMEs, with their approval, it could correct the problem by itself.
Global Product Monitoring Network Services Owner at a pharma/biotech company with 10,001+ employees

ThousandEyes pricing varies by setup and region, with mixed reviews on cost and complexity, influenced by Cisco agreements.

Project Manager at Procter & Gamble
My experience with pricing, setup cost, and licensing is that it comes in cheaper than alternatives.

Valuable Features

Nmap's powerful features offer comprehensive network analysis, vulnerability identification, and flexibility, making it essential for security audits and bug bounty projects.
ThousandEyes enhances visibility and efficiency with AI, customizable dashboards, seamless Cisco integration, and proactive issue resolution.
Nmap will be a little difficult for beginners because of the learning curve and the CLI-based system, but once you get the hang of it, it becomes very powerful.
Student at a consultancy with 11-50 employees
I measure the 70% improvement in customer experience through customer tickets and feedback after resolving issues, where previously, users faced problems and limited time on the platform, and after using ThousandEyes, the user time reached up to five to six hours a day, even for teams possibly totaling 30 hours a day.
Senior cloud engineering lead and IT project owner at KDD
ThousandEyes offers the best features including global internet and cloud visibility from distributed vantage points, application and network performance monitoring, real-time outage detection and incident alerts, end-to-end path visualization for rapid troubleshooting, proactive issue demarcation, and historical data.
Project Manager at Procter & Gamble
ThousandEyes has become critical for swift network troubleshooting as well, so anytime that there's potential issues with applications or we want to be proactive in resolving potential issues before they arise, ThousandEyes is really the platform that we're leveraging for WAN monitoring, Wi-Fi, latency, packet loss, etc.

Featured Reviews

Sai Aditya Panda - PeerSpot reviewer
Student at a consultancy with 11-50 employees
Penetration testing has become efficient as I identify open ports and security risks with confidence
Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.
Siddumanisria Mindi - PeerSpot reviewer
Network engineer at a tech vendor with 10,001+ employees
Monitoring has transformed internet visibility and speeds up resolving external service issues
ThousandEyes needs to specify unit consumption forecasting or scaling testing and deeper app analytics. It needs deeper out-of-the-box Layer 7 code or database-level insights. Additionally, it should unify the GUI with broader Cisco platforms and flatten the learning curve, adding better correlation with local laptop system metrics such as endpoint depth, CPU, RAM, or processes. ThousandEyes isn't designed to be a full-blown SNMP monitoring tool for on-premises infrastructure. While it tracks network paths effectively, it doesn't provide deep local device telemetry such as switch port buffer utilization, fan status, or power supply health. For full internal device monitoring, you'll still need to pair it with traditional tools such as SolarWinds or Cisco Catalyst Center.
