Research Special Projects Lead at a university with 501-1,000 employees5.0Languardian efficiently helped me identify torrent traffic for copyright violations, proving effective where other solutions failed. Though the GUI needed improvement, excellent support addressed minor issues, making it a cost-effective forensic tool.
Computer Network Specialist at a healthcare company with 1,001-5,000 employees5.0I value this product for its detailed bandwidth tracking and security insights, even for non-domain users. Deployment was easy, but I hope they improve the slow result loading time in future updates.
