Attacker surveilling network infrastructure — Intrusion Shield stops reconnaissance before it starts

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.

02 — The Problem

NO ONE IS
WATCHING THE
PARKING LOT.

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.

01

The network gets scanned

The attacker maps your ports, services, and topology. Most tools generate zero alert. He's taking notes. You don't know he's there.

02

Infrastructure gets mapped

Internal services, active hosts, communication patterns, all enumerated. The attacker now has a blueprint of your environment and knows exactly where the weaknesses are.

03

The move is made

Now he acts, because he's ready. He knows the layout. He planned for the guards. The breach isn't reckless. It's surgical. Recon made it possible.

Your team reacts. Too late.

The alert fires after access is gained. Your team is now in incident response: forensics, remediation, damage control. Everything the attacker was counting on.

03 — How We Fix It

WE BURN
THE BLUEPRINTS.

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 — Inbound

End the stakeout before it starts

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.

Intercept 02 — Outbound

Cut the cord before he calls his crew

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.

Works With Everything You Have

YOUR SIEM SEES
THE BREACH.
SHIELD PREVENTS
THE RECON
THAT MADE IT POSSIBLE.

Shield doesn't replace your security stack. It makes every tool in it work harder. Your SIEM has fewer incidents to triage. Your SOC team spends less time in reactive mode. Your firewall enforces rules on traffic Shield has already screened. Everything downstream gets better because Shield is upstream.

SIEM / SOAR

Less noise. Better signal.

Shield stops threats before they generate an alert. Your SIEM gets fewer events and higher-quality incidents worth investigating.

EDR / XDR

Upstream prevention, not just detection.

EDR catches what gets through. Shield stops what never should have reached the endpoint in the first place.

Firewall / NGFW

Smarter rules, cleaner traffic.

Your firewall enforces policies. Shield pre-screens every connection against 8.5B known-bad IPs before your firewall even sees it.

Threat Intel Feeds

Intelligence that acts, not just informs.

Most feeds tell you what to watch. Shield acts on threat intelligence automatically, the moment contact is made.

Why Intrusion

DETECTION
FINDS THE
BREACH.
WE PREVENT IT.

Unlike detection-first tools, Shield blocks before the attacker gathers a single data point about your environment. Most security tools are built to find the fire. Shield is built to stop the arsonist from casing your building.

vs

Detection tools alert after access

SIEMs, EDR, and XDR are designed to catch attackers who are already inside. They are excellent at what they do. Shield stops the attack before they ever get the chance to fire an alert.

vs

Firewalls guard known perimeters

Firewalls enforce rules on known traffic. They cannot identify malicious infrastructure they have never seen. Shield checks every connection against 8.5 billion known-bad IPs in real time.

vs

Threat intel feeds inform. Shield acts.

Intelligence feeds tell you what to watch. Shield acts on that intelligence automatically, blocking malicious infrastructure the moment it makes contact, inbound or outbound.

Trusted by Government

Built for
the most

networks
on earth.

Leadership

Led by a Former Federal CIO

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.

Heritage

Founded in 1983. Intelligence Since 2001.

Intrusion has protected federal infrastructure for decades. Our threat intelligence dataset has been built and refined since 2001, forged in environments that nation-state adversaries never stop targeting.

Scale

8.5 Billion Reasons to Be Confident

The largest IP reputation database of its kind. The same data that has protected classified networks is now available to every organization, regardless of size or sector.

Built For — Federal, State, Local & Education

YOUR NETWORK
IS A TARGET.
ACT LIKE IT.

Federal agencies face nation-state adversaries. Sheriffs' departments protect critical county infrastructure on shoestring budgets. School districts hold the personal data of hundreds of thousands of children. Attackers know it.

The recon playbook doesn't change based on who you are. Attackers case every target the same way. The only difference is whether you're watching the street outside.

Intrusion Shield deploys in minutes, requires zero baselining, and starts blocking malicious infrastructure the moment it's turned on, whether you're a cabinet-level agency or a county sheriff's office with three IT staff.

Federal

Agency & Defense Networks

Government-grade threat intelligence built from 20+ years of federal environment data. Designed for the security posture, compliance requirements, and adversary profile of federal networks.

State & Local Government

Municipalities & Law Enforcement

State and local agencies are among the most frequently targeted, and the most under-resourced. Shield delivers enterprise-grade protection without enterprise-grade complexity. Instant-on. No dedicated security team required.

Education / K-12 & Higher Ed

Districts, Campuses & Research Networks

Educational institutions hold sensitive student data, research assets, and open network architectures that attackers actively exploit. Shield stops reconnaissance before sensitive environments are mapped and staged for attack.

POSSE Program

Protecting Our Sheriffs' Security Everywhere

Intrusion's POSSE program deploys Shield specifically for law enforcement, protecting the agencies that protect communities. Purpose-built for the threat landscape facing sheriff departments across the country.

Defend the Game

EVERYTHING
WORTH PROTECTING
IS THE GAME.

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.

Critical Infrastructure

The Grid

Power, water, transportation. The systems that cannot fail are the ones attackers target first.

Public Safety

The Hospital

Ransomware on a hospital network is not a data breach. It is a threat to human life. Shield blocks the recon that makes it possible.

Community

The School

Children's data, research networks, open architectures. The most under-resourced environments face the same adversaries as the Pentagon.

Commerce

The Enterprise

Every company that moves product, processes payments, or holds customer data is a target. The attacker cased your network before you knew they existed.

We don't just protect networks.
We defend what's worth defending.
