Intel Brief

Before every cyberattack, there is a stakeout.

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.

The blind spot is obvious: 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.

Introducing Intrusion Shield
So how do we fix it?

Every attack depends on two things: mapping the target, and calling home with the data. Shield denies both. Not after the fact. Before either begins.

Shield runs every connection through a database of 8.5 billion known malicious IPs, forged over 20+ years in federal networks. Anything that matches gets blocked. Inbound and outbound. Automatically. The instant contact is made.

01 · INBOUND BLOCK
Shield stops the recon before it starts.
02 · OUTBOUND CUT
The call home never connects.
Why does this matter?

Detection finds the breach.
We prevent it.

Your SIEM, EDR, and firewall are built to handle threats that reach them. Shield means fewer threats reach them at all. One layer upstream. Everything downstream performs better.

vs SIEM / SOC

Less noise. Better signal.

SIEMs catch what gets through. Shield stops the recon that makes the attack possible. Your SIEM gets fewer events and higher-quality incidents worth investigating.

vs EDR / XDR

Upstream prevention, not just detection.

EDR catches what reaches the endpoint. Shield stops what never should have gotten there in the first place. Both layers working together is the strongest possible posture.

vs Firewall / Threat Intel

Intelligence that acts, not just informs.

Most feeds tell you what to watch. Firewalls enforce known rules. Shield acts on 8.5B IP reputation data automatically, the moment contact is made, inbound or outbound.

Built for the Most Targeted Networks on Earth

Government-grade intelligence.
Commercial-scale enforcement.

Born in Government Environments. Built for Modern Networks. Our threat intelligence has been running since 2001, forged in federal environments that nation-state adversaries never stop targeting. That same intelligence now defends organizations across every sector, at any scale.

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 been defending federal infrastructure since 1983. Our threat intelligence dataset has been built in the field since 2001, refined against the most persistent adversaries on earth.

Scale

8.5 Billion Reasons to Be Confident.

The largest battle-tested IP reputation dataset available to commercial networks. Built inside classified environments. Now working for yours.

From the field.

We were impressed with Shield's accuracy in preventing a cyberattack within the first week of implementation that would have otherwise taken place on one of our largest customer's networks.
Desmond Spencer, CTO, InnerCore Technologies
Many companies rely heavily on firewalls and segmentation to protect OT and SCADA networks, but Intrusion helps cover blind spots without the same complexity or cost.
Fernando Lara, CEO, Singular Security Inc.
Shield does what it claims to do. We were very impressed with Shield's alignment with what Intrusion says it does.
Frank Oelschlager, Former Research VP, IDC
