The Threat You Can't See From Your Network

Ransomware groups announce victims on dark web leak sites before — and sometimes instead of — encrypting data. Stolen credentials appear on criminal marketplaces hours after a breach. Sensitive documents turn up on forums before your team knows they're gone.

Traditional security monitoring doesn't see any of this. Binary Response runs continuous monitoring across the dark web infrastructure most relevant to your threat profile — and alerts you the moment your organisation appears.

What We Monitor

  • Ransomware leak sites — all major and emerging threat actor blog sites; first disclosure alerts before data is published
  • Criminal marketplaces — stolen credentials, session cookies, and access listings for your domains
  • Dark web forums — mentions of your organisation, domains, IP ranges, and key personnel
  • Paste sites and dump repositories — credential dumps, database leaks, and code repositories
  • Telegram and Discord channels — threat actor announcements and initial access broker activity
  • Supply chain exposure — monitoring for third-party disclosures that include your data

Alert Types

  • Tier 1 — Ransomware victim disclosure: Your organisation has appeared on a leak site. Immediate response required.
  • Tier 2 — Credential exposure: Employee credentials or session tokens found in marketplaces or dumps.
  • Tier 3 — Data or document exposure: Files referencing your organisation found in accessible repositories.
  • Tier 4 — Threat actor interest: Mentions in forums or initial access broker listings suggesting targeting activity.

From Alert to Response

Monitoring without response capability is just notification. Every Binary Response monitoring client has a direct line to our IR team. If a Tier 1 alert fires, your named point of contact is called within the hour — and response can mobilise immediately under your retainer or on an ad-hoc basis.

Frequently Asked Questions

How is this different from commercial threat intel platforms?

Commercial platforms provide broad intelligence across many industries. Our monitoring is tailored to your specific organisation — your domains, IP ranges, subsidiaries, key personnel names, and supply chain. We also combine automated monitoring with human analysis, so you receive contextualised alerts rather than raw data.

What happens when an alert fires?

You receive an immediate notification with context: what was found, where, what it means, and recommended next steps. For Tier 1 ransomware alerts, we call your designated contact directly. We don't send alerts and leave you to interpret them alone.

Can monitoring help if we've already had a breach?

Yes. Post-breach monitoring is particularly valuable — we watch for data appearing in marketplaces, confirm whether exfiltrated data is being sold or published, and provide evidence for your notification obligations.

Do you cover subsidiary companies and acquired entities?

Yes. We configure monitoring for all entities you want covered. M&A activity often creates coverage gaps — brief us on recent acquisitions and we'll extend monitoring immediately.

Is monitoring included in your IR retainer?

Yes — dark web monitoring is included in all Binary Response retainer tiers as standard.

Frequently Asked Questions

What exactly do you monitor on the dark web?

We monitor over 90 ransomware leak sites, threat actor forums, paste sites, marketplaces and Telegram channels. We track new victim listings, data dumps, credential leaks, initial access broker listings and threat actor communications that reference your organisation.

How quickly will I be alerted if my organisation appears?

Our monitoring platform runs continuously with checks every 15 minutes. When a new listing is detected, we generate an alert within minutes. Critical alerts include the threat actor group, data type, timeline, and recommended immediate actions.

Can you prevent our data from being published?

Once data is listed on a leak site, we can advise on negotiation options and help you understand what data is at risk. Through our ransomware negotiation service, we can engage with threat actors to discuss data removal. However, there are no guarantees once data reaches the dark web.

Do you need access to our systems to monitor the dark web?

No. Dark web monitoring is entirely external — we monitor threat actor infrastructure, not your network. There's nothing to install, no agents to deploy and no network access required.

Is dark web monitoring worth it if we already have a SOC?

Yes. Most SOCs focus on internal network monitoring and endpoint detection. Dark web monitoring covers the external threat landscape — leaked credentials, compromised data, and threat actor chatter. These are blind spots that even mature SOC operations typically miss.
