NEW! Data443 Acquires Vaikora – Real-Time AI Runtime Control & Enforcement for AI Agent
A compromised host is an externally observable system inside an organization that is communicating with attacker infrastructure. The communication may be data exfiltration, command-and-control beaconing, malware download, lateral-movement reconnaissance, or part of a multi-stage attack. TacitRed flags compromised hosts at internet scale by observing the NetFlow patterns between organizational assets and known attacker infrastructure.
Compromise detection from outside the perimeter sidesteps the limitations of internal-only tooling. An EDR product can be evaded if the attacker is careful; a compromised host that beacons to known C2 infrastructure is detectable from the network layer regardless of whether the endpoint agent saw the original payload.
This outside-in view also closes the time gap between compromise and detection. The 2025 industry average for time-to-detection across all attacks was several weeks. TacitRed’s external view typically surfaces compromise within hours of the first beacon.
Compromised host detection is one of the higher-value outputs of EASM programs. The detection mechanism is NetFlow analysis. The signal is attacker infrastructure observed in the host’s outbound traffic.
A regional healthcare system has a workstation that begins beaconing to an IP block historically used by a ransomware affiliate. TacitRed surfaces the compromise as a high-priority alert in the customer’s feed, leading to containment before the ransomware payload finishes staging. A second example: a manufacturer’s exposed VPN appliance starts communicating with newly observed attacker infrastructure. TacitRed flags it; the customer’s IR team confirms compromise and rotates credentials within the same business day.
TacitRed maintains a continuously updated mapping of public IP ranges to organizations across more than 13 million US companies. The mapping uses public registration data, DNS, BGP, and behavioral signals.
No. TacitRed observes from the public internet using its own sensor network. There is no agent, no tap, and no traffic forwarding required from the customer.
Continuously. New compromise indicators surface as soon as the underlying NetFlow patterns are observed, typically within minutes.
Yes, like any detection system. TacitRed provides confidence scoring and observable evidence with each alert so analysts can validate before escalating.
