The Invisible Phase of the Breach
Most security tools focus on the door (the firewall). But the most dangerous part of an attack is the "East-West" movement inside your network. After catching a toehold, an attacker spends days mapping your Active Directory, stealing hashes, and jumping from server to server until they find the admin credentials.
How Network Guardian Sees the Invisible
We don't look for "bad files"—we look for "bad behavior" on the wire.
Pass-the-Hash (PtH) Detection
The Network Guardian monitors SMB signatures. When we see NTLM authentication coming from a machine that doesn't own the corresponding domain account—a classic sign of a stolen hash—we flag the "Impossible Hash Interaction" instantly.
DCSync Alerting
DCSync is the "Nuke" of Active Directory attacks. It mimics a Domain Controller to request password hashes. 1-SEC knows exactly which IPs are authorized DCs. If any other machine initiates a directory replication request, we escalate it to CRITICAL at the network layer.
