Enterprise & Mid-Market

Your stack catches what it's looking for. Shield blocks what it isn't.

Shield gives enterprise and mid-market security teams a prevention-first network defense. Shield blocks malicious traffic at the network layer using the Global Threat Engine and 8.5 billion IP and DNS combinations refined since 2001.

Know More. Miss Less.

You already paid for a firewall, an EDR, and a SIEM. They do their jobs. They also leave the same gap open: traffic to and from infrastructure that has been flagged hostile somewhere else in the world. Shield closes it. Powered by the Global Threat Engine.

The question on your desk

Someone is asking you a question your stack can't answer.

Ransomware coordination traffic. Data exfiltration to known-bad infrastructure. Pre-attack reconnaissance from IPs that have been flagged hostile somewhere else in the world for years. Your firewall enforces policy. Your EDR hunts behavior on endpoints. Neither of them was built to evaluate the reputation of every connection your network attempts, in or out, in real time. That's the gap.

01
Outbound traffic is the blind spot.
Ransomware crews phone home for instructions before they encrypt. Exfiltration leaves through the same ports your users browse on. Your firewall sees the connection. Reputation signal is shallow. Shield evaluates every destination against the Global Threat Engine and drops the bad ones.
02
Pre-attack recon never gets caught.
Adversaries map your exposed surface for weeks before action. The traffic looks normal until it isn't. Shield matches inbound sources against decades of historical IP records and drops the recon at the edge before it returns useful data.
03
Detection-first stacks demand analysts you don't have.
Every alert is a queue. Every queue is a delay. Shield is prevention-first. The block decision happens autonomously without generating alerts. Your team prioritizes resolution, not triage.
What changes the day you turn it on

Pre-emptive, bi-directional enforcement. Out of the box.

Shield monitors traffic bidirectionally in real-time, giving you full visibility of every connection your network is making. Trusted IPs are permitted. Malicious connections are blocked. No alerts. No analyst review. No 24/7 SOC required.

Powered by the Global Threat Engine, informed by decades of historical IP records and the reputation of 8.5 billion IP/DNS combos, refreshed continuously. The first packet through Shield is the first packet evaluated against the full intelligence database.

Run Shield in Observe Mode first to surface what would be blocked before enforcement turns on. Quantify the gap, then close it. Bring the report to the board, the carrier, or the auditor.

  • No re-architecture. Shield coexists with your firewall, EDR, and SIEM.
  • No tuning window. No model to train. No baseline to learn.
  • No 24/7 SOC. Autonomous block decisions, evidence retained.
  • No vendor lock. One-year terms. Renewal options.
  • No agent on legacy or OT. Network-layer enforcement.

Why this works

Forty years inside the networks that mattered most.

Intrusion was founded in 1983. The threat intelligence has been gathered, curated, and refined for over 20 years in environments that could not afford to be wrong. CEO Tony Scott served as the third U.S. Federal CIO and led the federal response when the OPM breach was discovered two months into his tenure.

That heritage isn't decoration. It's why the Global Threat Engine sees what other vendors don't, and why the operators running the networks that matter most call us first.
