Intrusion Shield

The attack starts
before the alert fires.
Shield stops it first.

Shield is Intrusion's prevention-first network security platform. Shield blocks malicious inbound and outbound traffic at the network layer using the Global Threat Engine and 8.5 billion known-bad IP and DNS combinations refined since 2001.

Most security tools are built to catch attackers who are already inside. Shield blocks the reconnaissance that makes every attack possible before a single port sweep completes. Two intercepts. Both decisive. No baselining required.

BlockedInbound recon attempt - Port sweep from known hostile IP. Shield terminated before a single service was enumerated.
BlockedOutbound C2 callback - Compromised device attempted contact with hostile infrastructure. Connection killed before data moved.

What Shield Blocks That Others Miss

By the time your tools alert,
Shield already blocked it.

Detection tools are built to find attackers inside your environment. Shield is built to deny them the reconnaissance that got them there. Here's what slips past every other tool in your stack and what Shield stops cold.

Standard Stack MissesShield Stops
Inbound recon scans→Blocked before mapping starts
Unknown hostile IPs→8.5B database identifies on contact
C2 callback traffic→Connection killed before data moves
Months of tuning→Active enforcement from packet one
Attacker maps network→Attacker's map stays blank
Stage 1 Intercept
Reconnaissance. Stopped Cold
Attackers scan your infrastructure before launching a single exploit. Shield checks every inbound connection against 8.5B known-malicious IPs and blocks recon before the attacker maps a single service.
Stage 5 Intercept
C2 Callback. Before Data Moves
If a device is compromised, it will try to call home. Shield intercepts outbound connections to hostile infrastructure and kills them before data moves. The crew never gets the signal.
Stack Amplifier
Less Noise for Everything Downstream
By stopping recon and C2 traffic upstream, Shield removes the events that flood your SIEM, fatigue your SOC, and slow your EDR. Every tool downstream works harder because Shield is upstream.
Zero Baselining
No Tuning Period. No Wait.
Shield doesn't learn your environment before protecting it. It knows hostile infrastructure on contact. 20+ years of data on what hostile looks like. Active from packet one.
How Shield Works

Two intercepts. Both decisive.

Every attack follows the same chain. Shield breaks it at the beginning and cuts it at the end.

01
Stage 1 - Recon
Attacker begins reconnaissance
Hostile infrastructure attempts to scan your network. Shield checks every connection against 8.5B IP data points and blocks the attacker on contact before a single service is mapped.
Shield Blocks Here
02
Stage 2 - Access
Never reached
Without reconnaissance data, the attacker has no blueprint. Can't identify weaknesses. Can't plan the move.
03
Stage 3 - Exploit
Never reached
No access means no exploit. The attack chain is broken at Stage 1.
04
Stage 4 - Move
Never reached
No exploit means no lateral movement.
05
Stage 5 - C2 / Exfil
Shield's second intercept
If a device is ever compromised through another vector, Shield catches the outbound C2 callback. The connection to hostile infrastructure is killed before data moves. The attack is orphaned at both ends.

What You Get

Three outcomes. From day one.

Zero
Baselining Required
No tuning period. No rule configuration. No waiting. Shield knows hostile infrastructure on contact. 20+ years of threat intelligence data. Protection starts the moment it's turned on.
Less
Noise Across Your Entire Stack
By stopping recon and C2 before events are generated, Shield reduces what your SIEM triages, your SOC investigates, and your EDR contains. Everything downstream works harder because Shield is upstream.
More
Time Back for Your Team
When Shield is blocking the reconnaissance that generates alert storms, your team spends less time reacting and more time on threats that actually matter. Same team. Dramatically different workload.
Two Modes. Start Wherever You Are.

See what you are missing first.
Then block it.

Not ready to go straight to enforcement? Shield has an observe mode that shows you exactly what would have been blocked in your environment before you commit to protect mode. Most organizations are surprised by what they see.

Observe Mode
See everything. Block nothing yet.
Shield analyzes all inbound and outbound connections against 8.5B IP data points and shows you exactly what would have been blocked without enforcing anything. Your team gets a full picture of your threat exposure before making a deployment decision.
-Full threat visibility across all traffic
-No enforcement while you evaluate
-Report ready for your team before you commit
Protect Mode
Active enforcement. Zero alerts.
Shield automatically blocks malicious connections and documents every enforcement action without generating a stream of alerts for your team to review. Threats are stopped and logged. Your SOC does not receive an alert queue from Shield activity.
✓Autonomous blocking. No team action required
✓No triggered alerts. Threats documented, not alerted
✓Reports available on demand. No alert fatigue
The Traffic Sampling Problem

If you are only seeing
a sample of traffic,
what are you missing?

Most security tools inspect a sample of network traffic, not all of it. That means every connection they do not inspect is an opportunity an attacker can use without triggering a single alert.

Shield inspects every connection. Inbound and outbound. Not a sample. Not a subset. Every packet checked against 8.5B IP data points before it completes. That is the only way to guarantee you are not missing the attacker who is already in your parking lot.

🔴 Traffic sampling - blind spots attackers can use without detection
🔴 Unmanaged and unpatched devices often excluded from sampling entirely
🔴 Encrypted traffic often skipped. Exactly where attackers hide
🟢 Shield inspects every connection. No sampling, no blind spots
🟢 Unmanaged and unpatched devices covered. No agent required
Common Questions

We've heard the objections.
Here are the answers.

Objection 01
"We already have a firewall and an EDR. Why do we need Shield?"
Your firewall enforces rules on known traffic. Your EDR catches what reaches the endpoint. Neither one stops an attacker who's still mapping your network. Shield prevents the reconnaissance that makes attacks possible so your firewall and EDR see less volume and handle fewer incidents.
Objection 02
"How long before we see value?"
Shield requires zero baselining. Protection starts from packet one. Most clients see their first blocked threat within hours of deployment. Within days, you have a report showing exactly what it stopped.
Objection 03
"Is this going to create more noise and false positives?"
The opposite. Shield reduces noise across your entire stack by eliminating recon traffic that would otherwise trigger alerts. 99.999% accuracy on 8.5B IP data points means fewer false positives, not more.
Objection 04
"We don't have the team to manage another product."
Shield is designed for lean teams. Zero baselining means zero configuration sprint. Command Hub gives you one console for every deployment. And because Shield runs autonomously 24/7, it reduces your work queue. It doesn't add to it.
