Critical Infrastructure

The systems that
cannot fail are the
ones they target first.

Intrusion delivers prevention-first cybersecurity. The Shield platform blocks malicious network traffic before it reaches the endpoint, using the Global Threat Engine and 8.5 billion IP and DNS combinations refined since 2001.

Power grids, water treatment, transportation, and communications systems face nation-state adversaries who spend months mapping control environments before they act. Shield stops that reconnaissance before a single OT asset is identified - and cuts the outbound callback if anything reaches a connected device.

The Threat to Critical Infrastructure

They are not breaking in.
They are mapping your controls first.

Nation-state adversaries targeting critical infrastructure are not opportunistic. They are methodical. They spend months - sometimes years - conducting reconnaissance on OT and SCADA environments, mapping asset topology, identifying control pathways, and looking for the moment conditions favor an action.

Most critical infrastructure environments have significant IT security investment but limited OT-specific coverage. Shield covers both sides - blocking malicious infrastructure from reaching your IT network, and cutting outbound callbacks from any connected OT device that is compromised through a lateral pathway.

The blind spot: many critical infrastructure operators rely on firewalls and segmentation to protect OT and SCADA networks - but Intrusion helps cover blind spots without the same complexity or cost.

Vector 01
IT network reconnaissance used to map pathways into OT environments through historian servers, DMZ systems, and connected engineering workstations.
Vector 02
Nation-state pre-positioning operations that establish persistent access months before any action is taken - designed to survive detection and remediation cycles.
Vector 03
Outbound C2 traffic from compromised IT systems used to beacon back to adversary infrastructure and receive updated instructions.
Vector 04
Supply chain and remote access pathways used by vendors and contractors as initial reconnaissance and access vectors into control environments.
How Shield Protects Critical Infrastructure
IT-OT Boundary Protection
Block reconnaissance before it reaches your controls
Shield stops malicious infrastructure at the IT network layer before attackers can map pathways into your OT environment. The attacker never gets the blueprint they need to plan an action against your control systems.
Outbound Enforcement
Cut the callback before the crew gets the signal
If a connected device is compromised, Shield intercepts outbound C2 traffic and terminates it before data moves or instructions are received. Pre-positioned implants go dark.
OT and SCADA Blind Spot Coverage
Without the complexity of inline OT tools
Shield covers the blind spots that firewalls and segmentation leave open - without requiring inline deployment in your control environment. Protection at the IT layer before threats reach OT assets.
Zero Baselining
Active from the moment it is deployed
No tuning period. No learning phase that leaves you exposed while Shield figures out your environment. 20 years of threat intelligence means it recognizes hostile infrastructure on contact.
Why critical infrastructure operators choose Shield
  • ✓No inline OT deployment required
  • ✓Covers blind spots firewalls and segmentation miss
  • ✓DoD contract extended and expanded
  • ✓20 years of government-grade threat intelligence

What Critical Infrastructure Operators Get

Stop the mapping. Before the action.

Blind
Attackers Stay Blind to Your Controls
When malicious infrastructure cannot map your IT network, it cannot identify pathways into your OT environment. Shield denies adversaries the reconnaissance they need to plan an action against your critical systems.
Dark
Pre-Positioned Implants Go Dark
Shield's outbound enforcement cuts C2 callbacks from any compromised device. Implants that survived your detection tools lose their connection to adversary infrastructure - and the instructions never arrive.
Clear
Evidence for NERC, TSA, and CISA
Every blocked connection logged and reportable. Give regulators and auditors the evidence of a proactive security posture - with the specific threat categories Shield intercepted against your environment.
Why Intrusion

Government-grade intelligence.
Built for the most targeted networks on earth.

Intrusion was founded in 1983. Threat intelligence running since 2001 - forged in federal environments that nation-state adversaries never stop targeting. DoD contract extended and expanded. The same intelligence now protects critical infrastructure operators across energy, water, and transportation.

Heritage
Founded 1983. Intelligence Since 2001.
Forty years of company heritage. Threat intelligence built and refined since 2001 in federal environments, the same adversaries targeting your infrastructure have been in our database for decades.
Leadership
Led by a Former Federal CIO
CEO Tony Scott served as Federal CIO of the United States. The OPM data breach, which compromised 21.5 million records, was discovered two months into his tenure. He built Intrusion to ensure that kind of reconnaissance never reaches the blueprint stage, and made that intelligence available to critical infrastructure operators.
Validation
DoD Contract Extended and Expanded
The U.S. Department of Defense renewed and expanded its Shield deployment. When the most security-conscious organizations on earth keep expanding, that is the proof point that matters.

Regulatory Evidence

The mandates driving your budget.
Shield gives you the evidence.

Shield is not a compliance certification. It is a proactive security control that generates logged, reportable evidence of what was blocked and when - the documentation NERC, TSA, and CISA auditors and regulators want to see.

NERC CIP - Energy
Critical Infrastructure Protection
NERC CIP standards require utilities to identify and protect electronic security perimeters. Shield's inbound enforcement blocks malicious infrastructure from reaching your control system network and generates the logged evidence your NERC CIP audit requires for your Electronic Security Perimeter controls.
TSA Security Directives
Pipeline and Surface Transportation
TSA's cybersecurity directives for pipeline and surface transportation operators require network monitoring, access control, and incident reporting. Shield's bidirectional enforcement and logging supports your TSA directive compliance documentation with timestamped evidence of proactive controls.
CISA Guidance and KEV
Cross-Sector Critical Infrastructure
CISA's Known Exploited Vulnerabilities catalog and cross-sector security guidance emphasize pre-breach prevention. Shield's 8.5B IP reputation database includes infrastructure associated with known threat actors targeting critical sectors - blocking them on contact before your environment is enumerated.
Proof of Value

What you will learn
in a Shield POV.

The POV is not a demo. Shield runs in your actual environment against real traffic - and shows you exactly what it intercepts that nothing else in your stack caught. Clear success criteria agreed before it starts.

1 Inbound reconnaissance attempts against your infrastructure - what Shield blocked that your other tools did not flag
2 Outbound C2 traffic from any compromised devices - connections your EDR and firewall passed that Shield terminated
3 Hostile IP contacts your firewall and SIEM did not catch - categorized by threat type and severity
4 Full threat report formatted for your leadership team and auditors - ready to use before the first invoice
POV Timeline
Day 0 Success criteria agreed. Shield deployed. Active from packet one.
Week 1 First blocked threats visible. Initial threat report delivered.
Week 4 Full POV report. Clear decision framework. Your data, your call.

Is Shield Right for You?

We will tell you honestly
if we are not the right fit.

Not every security requirement is a Shield requirement. We would rather tell you upfront than waste your time in an evaluation that does not fit your needs. Here is when Shield is not the right answer.

- Your primary requirement is deep payload DPI malware scanning. Shield operates at the IP reputation and connection layer. It is not a malware sandbox or payload inspection tool.
- You want a full SOC replacement or MDR-only service. Shield is a prevention layer, not a managed detection and response offering.
- You cannot deploy anything inline and will not run a POV. Shield requires a proof of value to demonstrate fit - we do not ask you to buy before you see it work.
- You want a pure firewall replacement and will not consider a complementary control. Shield works alongside your firewall - it does not replace it.
Shield is the right fit if:
✓You have a SIEM or EDR already and want to reduce the noise they see
✓You want protection that starts before an alert fires - not after
✓You need to prove due diligence to auditors or leadership with logged, reportable evidence
✓You want something that is active from day one without a months-long tuning period
✓You are willing to run a short POV to see what Shield blocks in your actual environment
