What TacitRed monitors and what it does with the signal when it finds a hit

Product Updates · Nov 12, 2026 · 3 min read

External identity risk is specific: a credential found in a breach dump, a leaked API key in a public repo, an employee account seen authenticating to known-malicious infrastructure. The problem is that most organizations find out about those signals weeks late, if at all, and the detection comes from a SIEM alert rather than from a system that was actively watching for the exposure.

TacitRed is Data443's identity and external threat intelligence platform. It monitors compromised credentials, dark-web exposure, leaked secrets, and identity risk continuously. When it finds a match, it pushes the signal into enforcement rather than holding it in a dashboard for a human to act on.

What TacitRed is actually watching

The platform covers four categories of external identity risk:

• Compromised credentials: usernames and passwords appearing in breach data, paste sites, or underground markets
• Dark-web exposure: account identifiers, internal addresses, or sensitive references surfacing in threat actor forums or marketplaces
• Leaked secrets: API keys, tokens, and connection strings found in public repositories or data dumps
• Identity risk from network behavior: anomalous external connections tied to known-malicious infrastructure, detected through internet-scale NetFlow telemetry

The NetFlow layer matters because it catches the behavioral signal that credential data alone misses. If an account is making external connections to infrastructure that TacitRed's telemetry has flagged as malicious, that is a risk indicator independent of whether the credential has appeared in a breach file.

What happens when a hit is found

Detection without enforcement is a report. TacitRed is built to close that gap by pushing high-confidence indicators directly into the tools security teams already use for response.

TacitRed ships as a Microsoft Sentinel solution, so indicators flow into the SIEM workspace without custom connector work. It also pushes directly into CrowdStrike Falcon and SentinelOne for automated enforcement at the endpoint and identity layer.

A concrete sequence: TacitRed identifies a corporate credential in a fresh breach dataset. It pushes the indicator into CrowdStrike Falcon as a high-confidence identity risk signal. Falcon's policy can then trigger a session revocation, force a re-authentication challenge, or flag the account for SOC review, depending on how the enforcement policy is configured. The SOC analyst sees the incident in Sentinel with the TacitRed context already attached, not a raw alert that requires separate enrichment work.

The NetFlow layer in practice

Most identity threat intelligence platforms work from static datasets: breach files, dark-web crawls, known-bad IP lists. The NetFlow telemetry TacitRed consumes adds a live behavioral dimension.

Here is a specific scenario. An employee's device starts making repeated connections to an IP block that TacitRed's telemetry has associated with command-and-control infrastructure. No credential has appeared in a breach file yet. The behavioral signal alone is enough for TacitRed to surface an indicator. The analyst gets the alert before data moves out, not after.

This is especially relevant for detecting staged attacks, where the credential compromise and the actual abuse are separated by days or weeks of reconnaissance.

Integration with the broader security stack

TacitRed does not require a rip-and-replace of existing tooling. The Sentinel solution installs from the Microsoft Sentinel Content Hub. The CrowdStrike Falcon and SentinelOne integrations push indicators in formats those platforms already consume.

If your environment also uses Vaikora for AI agent enforcement, TacitRed's identity risk signals can feed into Vaikora's policy evaluation layer, so an AI agent running under a compromised service account identity can be blocked or held for approval before it executes a tool call. The enforcement happens at the point of action, not after the fact.

What to check next

If you are evaluating TacitRed for your environment, three things are worth confirming before you start:

• Whether your Sentinel workspace is already set up to receive indicators through the Content Hub, since that determines how quickly you can get the solution running
• What enforcement actions are configured in CrowdStrike Falcon or SentinelOne for identity risk indicators, because the value of the signal depends on what happens automatically when it arrives
• Whether your credential monitoring currently covers API keys and tokens in addition to username-password pairs, since leaked secrets are a distinct exposure category with different remediation steps
