What Is Cyber Threat Intelligence Software?

CTI software collects threat data from external sources and filters it to show what’s relevant to your organization. The job is to give your security team intelligence they can act on, instead of a firehose of indicators that drown the signal.

Most CTI platforms focus on IOC feeds. Those are useful for blocking known infrastructure, but they miss the credentials and data attackers actually use to break in. According to Verizon’s 2025 DBIR, 88% of web application breaches involve stolen credentials. Those credentials don’t show up in IOC feeds. They appear in stealer logs sold on Telegram channels, in dumps on ransomware leak sites, and in IAB listings where attackers sell network access.

Dark web CTI watches the attacker supply chain: the stolen data they buy and sell before launching an attack. Coverage includes non-human identities too. API keys, OAuth tokens, and service account secrets get harvested from infected employee devices alongside user passwords. Your employee’s credential can sit in a stealer log for weeks before someone buys it and uses it. That window is your chance to reset the password and revoke the session before an attacker logs in.

Why Dark Web Intelligence Beats Generic IOC Feeds

Skip the IOC Firehose

Most CTI tools deliver thousands of indicators you’ll never act on. Breachsense surfaces only the credentials and leaked files tied to your domains. Less triage, more action.

Catch Threats Before They Reach Your Network

EDR catches attackers after they’re inside. SIEM correlates what’s happening in your logs. Dark web CTI watches the places where attackers buy credentials before they use them against you. The earlier you spot the exposure, the cheaper the fix.

Integrate via API

Push alerts into your SIEM or SOAR through a REST API and webhooks. Trigger automated password resets and session revocations without manual triage. The dark web API is the integration layer.

Who Uses Cyber Threat Intelligence Data?

Same CTI data, different jobs across the team. Here's how four common security roles use Breachsense, and which data they actually pull.

  • SOC Analysts

    Alert triage and response

    You work a queue and want enriched JSON that drops into your SIEM, fires the right playbook, and lets you close tickets without manually pivoting across tools.

    What they use:
    SIEM webhookssource-attributed credentialsstealer log context
  • Threat Hunters

    Credential and access hunting

    You hunt for exposures attackers will exploit later this quarter. Pivot from a leaked credential to other accounts on the same device, or from an IAB listing to known infrastructure.

    What they use:
    Per-asset historyfull-text leak file searchAPI for bulk pivots
  • CTI Leads

    Program owners and intel managers

    You're building a CTI program and need sources that produce actionable output instead of IOC volume. Score vendors on coverage and how often their alerts trigger real action.

    What they use:
    Source coverage transparencyleaked vendor dataalert-to-action metrics
  • Incident Response

    Post-breach scoping

    You're inside an active incident and need to know what the attacker already has. Search leaked files from ransomware attacks and rebuild the exposure picture before the next press cycle.

Frequently Asked Questions

CTI software collects and analyzes external threat data from sources like dark web forums, stealer log channels, and ransomware leak sites. It filters that data against your organization’s assets so your security team acts on real threats instead of generic feed noise. Breachsense focuses specifically on the credentials and data attackers use, not just the infrastructure they operate from.
A threat intelligence platform (TIP) manages the full intelligence lifecycle from collection through analysis to dissemination. Dark web monitoring focuses on criminal sources where stolen credentials and leaked files appear. TIPs are broader. Dark web monitoring is deeper on credential exposure and tends to need less analyst time before alerts become actionable.
At minimum: infostealer channels where stolen credentials appear within hours of infection, ransomware leak sites where attackers dump stolen files, and hacker forums where initial access brokers list network access. Dark web marketplaces matter too. The more sources covered, the fewer blind spots in your exposure picture.
CTI software can’t block attacks directly, but it catches threats before they’re exploited. When CTI software finds your employees’ leaked passwords in a stealer log, you can reset them before an attacker tries credential stuffing or VPN logins. That stops the breach before it starts. The earliest place to break the kill chain is at the credential layer.
Most CTI platforms offer API access that pushes alerts into your SIEM or SOAR. A typical workflow: CTI detects a leaked credential and sends an alert via webhook. Your SOAR triggers an automated password reset, kills the active session, and creates an incident ticket. Manual triage starts only when the playbook can’t resolve it cleanly.
Yes. Stealer logs capture every saved credential on an infected device, including API keys, OAuth tokens, AWS access keys, and service account secrets. These machine credentials matter on engagements because they rarely rotate, bypass MFA by design, and often hold broader permissions than user accounts. Query by target domain and Breachsense returns machine credentials alongside user passwords.
Vulnerability scanners find weaknesses in your own systems, like unpatched software or misconfigured services. CTI software monitors external sources for threats targeting you, like leaked passwords or exposed files. They solve different problems. Most security teams run both: scanners cover the inside, CTI covers the outside.
