Network Threats Detected

How does it work?

The patented Decision Engine technology consumes a data feed from the firewall, automatically scores each connection using a blend of proprietary analytics of more than 100 threat feeds (open source and commercial), and then automatically updates the firewall’s block list to block high-risk connections.

"[Network Defender] gives me peace of mind and one less thing to worry about."
