Intrusion Shield blocks malicious connections before the attack begins.
Inbound recon. Outbound C2. Stopped at contact.

Before any attacker launches a single exploit, they spend weeks in the stakeout. Scanning. Mapping. Learning every exit. Most security tools are pointed at the vault. Nobody's watching the street outside. We do.
A bank robber doesn't walk through the front door on day one. He cases the joint first. He sits in the parking lot. He maps the cameras, counts the guards, studies the schedule, and identifies every exit. Then, and only then, does he make his move.
Cyber attackers work the same way. Before a single file is touched or a single credential is stolen, they spend weeks, sometimes months, on the stakeout. Scanning your network. Mapping your infrastructure. Learning exactly where to hit.
Here's the problem: most security tools are pointed at the vault. Nobody's watching the street outside. By the time an alert fires, the attacker already knows your building better than you do.
Intrusion Shield catches attackers during reconnaissance, before they gather a single data point about your environment, and again the moment a compromised device tries to call home. Two intercepts. Both decisive.

Shield checks every inbound connection against an 8.5 billion IP reputation database and blocks reconnaissance before the attacker maps a single service. He pulls up outside your building. Shield tells him to keep driving.
If a compromised device attempts to reach hostile infrastructure, Shield intercepts and terminates the connection before data moves. The call home never completes. The crew never gets the signal. The job gets called off.
Shield doesn't replace your stack. It stops threats before they reach it, so every tool downstream sees less noise and handles fewer incidents.
Intrusion was founded in 1983. Our threat intelligence has been running since 2001, forged in federal environments that nation-state adversaries never stop targeting. That intelligence is now available to every organization, regardless of size or sector.
CEO Tony Scott served as Federal CIO of the United States. He operated at the highest levels of government cybersecurity and built Intrusion to that standard.
Intrusion has protected federal infrastructure for decades. Our threat intelligence dataset has been built and refined since 2001, forged in environments nation-state adversaries never stop targeting.
One of the most comprehensive IP reputation databases in the industry. The same data that has protected classified networks is now available to every organization, regardless of size or sector.
Every attacker needs information before they can move. Deny them that information. Intrusion blocks reconnaissance, cuts off malicious infrastructure, and stops bad outbound communication before it turns into an incident.
