Intrusion

What Intrusion does

Intrusion Inc. is a Plano, Texas-based, NASDAQ-listed (INTZ) cybersecurity company that sells the Shield platform, a prevention-first network security product that blocks malicious connections bi-directionally based on reputation lookups against a proprietary Global Threat Engine containing 8.5 billion IP and DNS combinations accumulated since 2001. The platform spans four deployment modes: Shield OnPremise (10 Gbps in-line hardware appliance), Shield Stratus (cloud-native packet filtering for AWS and Azure, generally available on both hyperscaler marketplaces since December 2025), Shield Endpoint (reputation filtering and ZTNA for Windows and Android), and Shield Sentinel (100 Gbps monitor-only visibility), all managed through Shield Command Hub.

The company generates the substantial majority of its revenue from U.S. government customers — 94.6% of FY2025 revenue of $7.1 million came from federal and state government entities — and goes to market through direct field sales for large public-sector accounts, a growing channel partner program (distributors, resellers, MSSPs), and cloud marketplace listings. Pricing is quote-based and not publicly disclosed, with revenue recognized on a subscription/contract basis. Recent reported financial performance includes a 22.9% revenue increase in FY2025, a 75.9% gross margin, a net loss of $9.1 million, $3.6 million in cash at year-end 2025, and a Q1 2026 revenue decline of 50% year-over-year driven by delays on a key Department of War contract, prompting a $3 million secured financing and an auditor going-concern warning. The leadership team, led by CEO Tony Scott, has been refreshed in early 2026 with senior public-sector, channel, and marketing hires to support diversification beyond a single federal account.

Core offering

Intrusion is a prevention-first cybersecurity company that sells the Shield platform, powered by the proprietary Global Threat Engine containing 8.5 billion IP and DNS reputation combinations built since 2001. The platform blocks malicious network connections bi-directionally and in-line through on-premise hardware appliances (Shield OnPremise), cloud-native deployments for AWS and Azure (Shield Stratus), endpoint reputation filtering (Shield Endpoint), and monitor-only visibility (Shield Sentinel), with centralized management via Shield Command Hub.

Product overview

Intrusion offers the Shield platform, a prevention-first cybersecurity solution combining threat intelligence, identification, and automated response. The platform comprises multiple deployment options: Shield OnPremise (hardware appliance), Shield Stratus (cloud-native for AWS/Azure), Shield Endpoint (device-level reputation filtering), and Shield Sentinel (monitor-only visibility). The Global Threat Engine and TraceCop threat intelligence database power all Shield products with 8.5 billion IP and DNS combinations built since 2001. Shield Command Hub provides centralized management across enforcement platforms. The company specializes in blocking outbound malicious connections to prevent data exfiltration and C2 communications.

• Cisco: Cisco's Firepower and Talos threat intelligence offerings provide IDS/IPS and threat intelligence directly comparable to the Shield Platform and Global Threat Engine. Cisco is a major network security incumbent with deep government and enterprise penetration.
• Palo Alto Networks: Palo Alto Networks is a multi-billion-dollar cybersecurity platform that Intrusion explicitly benchmarks Shield against (VM-Series). It offers network firewalls, IPS/IDS, and cloud security across on-prem and cloud, making it the closest broad incumbent with overlapping network security capabilities.
• Zscaler: Zscaler is a cloud-native security platform that Intrusion explicitly benchmarks Shield Stratus against in its product datasheets. Both target cloud egress filtering and zero-trust access for enterprise and government workloads.
• CrowdStrike: CrowdStrike's Falcon platform combines endpoint protection with threat intelligence and is increasingly expanding into network and cloud security. It competes with Shield Endpoint and the underlying Global Threat Engine in enterprise and government security budgets.

Direct peers

• Vectra AI: Vectra AI delivers AI-driven network threat detection and response, comparable to Shield Sentinel and the threat-hunting/consulting services Intrusion offers. It focuses on enterprise SOC use cases with behavioral detection across network traffic.
• Corelight: Corelight provides network detection and response (NDR) built on Zeek, offering deep packet inspection and threat hunting similar to Shield Sentinel's monitoring capabilities. It targets enterprise and government SOC teams with comparable threat-intelligence-driven network analytics.
