Featured Reviews

Sulesh PK - PeerSpot reviewer
Monitoring and Operations Pilot at Egis S.A.
Experience enhanced monitoring with real-time alerts and efficient support
I would like to see automation in the poller features, as currently, the poller is not automated. If we could automate the addition or removal of hosts in the poller, it would improve efficiency. Sometimes, Centreon does not show the status of services as updated, which should be addressed. Additionally, enhancements are needed in identifying configuration issues, providing real-time alerts in case of issues, and improving the HTTP configuration tasks, as Centreon does not currently display issues with HTTP links, requiring manual investigation.
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.
