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.

01
BLOCKED!

Block the Recon

Before attackers strike, they scan. Shield identifies and blocks reconnaissance activity the instant it touches your network. The stakeout never happens.

02
SEVERED!

Cut the Call Home

Compromised endpoints try to phone home. Shield severs outbound connections to known C2 infrastructure before a single byte leaves your network.

03
SCANNED!

Evaluate Every IP

Every connection, inbound and outbound, is checked against 8.5 billion addresses with behavioral, historical, and reputation intelligence. Nothing gets a free pass.

04
DENIED!

Guard Every Environment

On-prem, cloud, endpoint, data center. Shield deploys everywhere your network lives, managed from one console. Total coverage.

Shield Ecosystem

One team. Every threat surface.

Each member of the team represents a core capability of the Shield platform. Together, they form the most complete prevention-first security system available.

Why does this matter?

Detection finds the breach.
We prevent it.

Your SIEM, EDR, and firewall handle threats that reach them. Shield means fewer threats reach them at all.

Shield by Sector

Your environment. Your rules.

Every network has a different threat profile. Shield adapts to yours.

Origin Story

Government-grade intelligence.
Commercial-scale enforcement.

Our threat intelligence has been running since 2001, forged in federal environments that nation-state adversaries never stop targeting.

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 1983. Intel Since 2001.

Over 40 years defending critical infrastructure. Threat intelligence built in the field, refined against the most persistent adversaries on earth.

Scale

8.5 Billion Reasons.

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
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
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.
