Born in Government Environments. Built for Modern Networks.
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.
Intercept 01 stops inbound recon. Intercept 02 cuts the outbound call home. Two points of failure for the attacker, before and after the perimeter.
Shield checks every inbound connection against 8.5 billion known malicious IPs 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.
Six deployment options. One intelligence layer. Managed from a single console regardless of where your environment lives.
Shield doesn't replace your stack. It stops threats before they reach it, so every tool downstream sees less noise and handles fewer incidents.
The game is your network. Pick your position.
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.
The Intrusion Partner Network gives MSPs a prevention-first product their clients cannot find anywhere else, with the margin structure, onboarding support, and technical resources to make it stick.
People think the game is a sport.
The game is the power grid. The game is the hospital that can't go dark. The game is the school district that holds your child's records. The game is the election, the supply chain, the water treatment plant, the financial system that moves trillions while you sleep.
Every attacker who sits in a parking lot and cases a building is playing a game. They study. They plan. They wait for the moment your defenses look the other way.
Intrusion is built for the people who refuse to let them win.
What customers, channel partners, and independent analysts say about Intrusion Shield.
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.
