See what the dark web already knows about you
Threat intelligence powered by Signals — continuous dark web monitoring, leaked-credential and infostealer-log alerts, and ransomware leak-site tracking. Start with a free exposure check.
Threat intelligence from Passeca is powered by Signals, which continuously monitors darknet markets, paste sites, criminal forums and infostealer-log repositories for exposure to your organisation — leaked credentials, stolen data, ransomware leak-site listings and brand abuse — and alerts you the moment it appears.

What is threat intelligence?
Operationally, threat intelligence is early warning — the knowledge that lets you close a hole before an attacker walks through it.
Threat intelligence is evidence-based knowledge about threats and threat actors — their tools, techniques, targets and indicators — collected from sources attackers themselves use. The value is not the data but the action it enables: resetting a credential before it is used in an attack, blocking an indicator before it reaches your network, or learning you are named on a ransomware leak site before encryption begins.
Passeca delivers this operationally through Signals, which indexes billions of records and integrates with PassIRP, Slack and Telegram so findings reach the people and systems that can act on them.
What Signals covers
Dark web monitoring
Darknet markets, paste sites and criminal forums for references to your organisation.
Leaked credentials
Email addresses and passwords exposed in breaches, so you can force resets before abuse.
Infostealer logs
Cookies, session tokens and credentials stolen by infostealer malware — a prime attack entry point.
Ransomware leak-site tracking
Monitoring of ransomware group leak sites so you learn of a listing early.
Brand abuse
Lookalike domains, impersonation and fraudulent use of your brand.
Executives & supply chain
Monitoring of key identities and third-party exposure relevant to you.
From dark-web signal to remediation
- 01
Continuous monitoring
Signals continuously surveils darknet markets, paste sites, criminal forums and infostealer-log repositories for references to your domains, brands, executives and email addresses.
- 02
Triage & enrichment
Findings are validated and enriched with context — severity, the dataset they appeared in, and the assets or identities they expose — so you act on real exposure, not raw noise.
- 03
Alerting
You receive actionable alerts through your chosen channel — SIEM (PassIRP), Slack or Telegram — with the evidence and remediation guidance needed to respond immediately.
- 04
Response & remediation
Passeca supports or executes the response: credential resets, account takedowns, leak-site tracking, and — where it indicates an active intrusion — escalation into incident response.
Powered by Signals
Signals is Passeca's threat-intelligence platform — continuous surveillance with 40B+ indexed records. Email, Slack and Telegram alerts on every plan; SIEM and SOAR export from Professional.
Signals continuously indexes darknet markets, paste sites, forums and infostealer-log repositories — billions of records — and checks them against your domains, brands and identities. Findings are validated and enriched, then delivered through the channel you choose. Because Signals is Passeca's own platform, intelligence flows directly into PassIRP and PassAI-Guard as detection and enrichment context, not as a separate, disconnected report.
See the Signals platform page for the full capability set, or run the free exposure check to see it act on your domain.
Who needs threat intelligence?
- You hold credentials that could be leaked — any organisation with staff accounts is exposed to infostealer compromise.
- You are a ransomware target — manufacturing, healthcare, finance and public sector benefit most from early leak-site warning.
- Your brand is impersonated — lookalike domains and phishing undermine customer trust.
- You must evidence monitoring — NIS2 and DORA expect proactive threat-intelligence capability.
