Custom Firewalls

Enterprise and state-level network defense perimeters engineered around your specific threat model, not a vendor's default ruleset.

Off-the-shelf firewalls are built for the median customer. State and enterprise-critical networks need perimeters designed around their actual adversaries. AftPak builds custom-engineered firewall and network defense infrastructure, from rule engines to inspection hardware integration, with full source-level auditability.
