| What you get | Prevention of known-bad connections with full evidence of what was blocked. |
CISA has named utilities, ports, transit, and energy specifically. Pre-positioning is the pattern: adversaries inside the network for months, mapping connections, waiting for instructions. Your firewall didn't catch them on the way in. Your EDR isn't looking for them where they live. Your OT engineer won't let you put anything new on SCADA, and your IT team is two people. Shield gives your board the answer it's asking for, without touching the OT environment.
Volt Typhoon-class adversaries don't kick the door down. They live inside the network for months, mapping connections, learning operations, then waiting for instructions. Detection-based tools need to know what to look for. Shield doesn't. It evaluates every inbound and outbound connection against decades of historical IP records and drops the ones that match known hostile infrastructure. Both ends of the loop close at once.
TraceCop catalogs the historical behavior, associations, and reputational risk of IPv4 and IPv6 addresses, domain names, and hostnames. Built on years of gathering global internet intelligence and supporting government entities, this data forms the backbone of Intrusion's commercial solutions.
When a connection is attempted to or from your network, Shield checks TraceCop for historical context: who has this IP communicated with, what infrastructure has it been associated with, what is its reputational risk. Hostile destinations and sources are dropped before the handshake completes.
Flat OT segments behind decade-old firewalls. Vendor remote access nobody documents well. An OT engineer who won't cooperate with anything that touches SCADA. Shield was built around those constraints, not despite them.
Week one: Shield OnPremise deploys at the IT-OT boundary in Observe Mode. Week two: we surface inbound recon and outbound coordination traffic in your environment. Week three: the findings are packaged as a written report of nation-state-attributed activity, mapped to the CISA advisory, ready to bring to the board, the GM, or your sector's ISAC.
Government procurement vehicles available. One-year terms. No multi-year commitments.
