VPN gateways and other internet-facing security infrastructure remain attractive
targets because they can provide direct access to corporate networks. Attackers 
can exploit software vulnerabilities before patches are available or during the 
period when organisations are testing and deploying fixes.

Stolen credentials create a second route of attack. Where multi-factor authentication
is not in place, compromised login details can allow criminals to access remote 
systems without exploiting a technical vulnerability.

Corero’s Zero Trust Admission Control, or ZTAC, is designed to reduce these risks
by limiting which sources are allowed to reach critical network services in the 
first place.

The system can automatically block traffic from sources associated with malicious
activity, including bots, Tor exit nodes, anonymising proxies and other untrusted
infrastructure. This filtering takes place before the traffic reaches a VPN gateway
or next-generation firewall.

The approach is intended to reduce the attack surface at the edge of the network.
Cybercriminals frequently use concealed or temporary infrastructure to scan systems
for vulnerabilities, test stolen credentials and launch attacks while making their
origins harder to trace. Blocking these sources earlier can reduce the amount of
hostile or unwanted traffic reaching remote-access systems.

Corero is applying a zero-trust principle to internet-facing infrastructure by challenging
the assumption that every internet connection should automatically be allowed to
reach a login page.
