- We index leaked files from ransomware attacks and enable full-text search across all content. Search for your company name, employee names, or any string to find your data in vendor breaches.
- We scan infostealer channels for leaked credentials and crack hashed passwords to plaintext. Find an infected employee? Pivot on their username to see every service they logged into.
- Set up monitoring for your domains, IPs, or specific text strings. Get alerts via webhook or email when your data appears.
- Query our dark web API during incident response to search leaked files and pull complete breach history.
- Push alerts to your SIEM or SOAR. Automate password resets. No manual file review required.
Your Perimeter Tools Can’t Stop Stolen Credentials
86% of breaches involve stolen credentials. Firewalls and EDR can’t stop attackers who already have valid usernames and passwords. By the time you notice unusual logins, the damage is done.
Breachsense shows you leaked credentials before attackers use them. We monitor dark web sources that other platforms can’t access. When your employees’ passwords appear in stealer logs or ransomware dumps, you’ll know within hours.

Search Leaked Breach Files for Your Data
When vendors get breached, your data ends up in ransomware dumps. Breachsense indexes leaked files and lets you search for your company name, employee names, or any string. We also scan infostealer logs for leaked credentials and crack hashed passwords to plaintext.
Use us for incident response, pen testing, vendor risk monitoring, or continuous breach monitoring. Know exactly what was exposed in any breach affecting your supply chain.

How It Works
What Makes Breachsense Different
Full-Text Search on Leaked Files
Search across millions of documents from ransomware attacks. Find your company name, employee names, or any string in vendor breach dumps. Know exactly what was exposed without reviewing thousands of files.
Credentials From Stealer Logs
We index credentials from infostealer channels within hours of exposure. Crack hashed passwords to plaintext. You’ll know exactly which accounts to reset before attackers weaponize them.
API-First for Security Teams
Query leaked files and credentials via API. Push alerts to your SIEM or SOAR. Automate password resets. Built for integration, not dashboard watching.
Real-Time Dark Web Monitoring Built for Security Teams
Breachsense is a dark web monitoring and breach detection platform built for security teams who need to stay ahead of threats. Breachsense continuously monitors criminal marketplaces, private forums, ransomware leak sites, and attacker channels to detect your organization’s exposed data in real-time.
Why Security Teams Choose Breachsense
According to IBM’s 2025 Cost of Data Breach Report, the average data breach costs $4.44 million. Most organizations discover their compromised credentials weeks or months after attackers already have access. By the time a breach hits the news, the damage is done.
Breachsense changes this equation by detecting compromised credentials and leaked session tokens the moment they appear on the dark web. This gives you time to reset passwords, revoke tokens, and shut down compromised systems before attackers can exploit them.
Our platform monitors sources other tools can’t access. We track:
- Criminal marketplaces where stolen credentials and malware logs are bought and sold
- Private attacker channels on Telegram and IRC where zero-day exploits and attack plans are shared
- Ransomware gang leak sites where stolen data is published when ransoms aren’t paid
- Infostealer malware logs containing credentials harvested from infected devices
- Public breach dumps and paste sites where data is freely shared
Every data source is continuously indexed and enriched. Hashed passwords are cracked to plaintext. Multiple search paths are created. The result: actionable threat intelligence you can use immediately to prevent attacks.
Built for Security Operations
Breachsense is designed for how security teams actually work. Configure monitoring for your domain names, IP addresses, hardware IDs, or specific search terms. Get instant alerts via webhook or email when relevant data appears. Query our dark web API to retrieve historical breach data during incident response investigations. Integrate with your SIEM, SOAR, or ticketing system to automate remediation workflows.
Our API-driven platform makes automation simple. When credentials leak, your security tools can automatically reset passwords, revoke access tokens, or trigger incident response playbooks without manual intervention. This automation is critical when minutes matter.
Real-World Use Cases
Incident Response Teams use Breachsense during active investigations to pivot on usernames, passwords, and IP addresses. When ransomware hits, our data helps identify the initial access vector and scope of compromise.
Enterprise security teams use Breachsense to protect employees and customers from credential stuffing attacks by monitoring for leaked corporate credentials.
Managed service providers monitor multiple clients from a single platform. Detect vendor breaches that could expose client data. Provide continuous third-party risk management as a value-added service.
Penetration testers and red teams use real-world breach data to test defenses. Conduct realistic assessments using the same data attackers already have about your organization.
Whether you need continuous monitoring, incident response intelligence, or security assessment data, Breachsense gives you the intelligence you need to stop cybercrime before it happens.

Frequently Asked Questions
Breachsense monitors more sources than competing platforms, including private attacker channels and criminal marketplaces other tools can’t access. We detect breaches in real-time with instant alerts, not batch processing delays. Our platform provides data enrichment by cracking hashed passwords to plaintext and adding threat context. The dark web API offers flexible integration with any security tool, not just pre-built connectors.
Dark web monitoring lets you detect compromised credentials before attackers use them. You can reset passwords and revoke access before credential stuffing attacks succeed. It provides early warning when your data appears on criminal marketplaces or ransomware leak sites. Continuous monitoring prevents breaches instead of just responding after damage is done. You’ll also detect third-party vendor exposures that could impact your business.
Breachsense continuously scans dark web sources 24/7 using automated crawlers and intelligence collection. The moment your credentials or data appear on a criminal marketplace or forum, our system indexes it and triggers an alert. You can receive notifications via webhook or email within minutes of exposure. This lets you reset passwords and revoke access before attackers exploit the breach. Our real-time detection is faster than platforms that use batch processing.
Yes. The average data breach costs $4.44 million according to IBM’s 2025 Cost of Data Breach Report. Dark web monitoring costs a fraction of that while preventing breaches before they happen. You’ll detect compromised credentials weeks or months before they become public knowledge. Early detection means you can act before attackers weaponize stolen data. For organizations handling customer data or facing compliance requirements, it’s essential.
Breachsense monitors criminal marketplaces where stolen credentials are sold, private attacker channels on Telegram and IRC, ransomware leak sites where victims’ data is published, and infostealer logs containing harvested credentials. We also track public breach dumps, paste sites, and code repositories. This coverage means you see threats other platforms miss.
Enterprise security teams use Breachsense to protect employees and customers from credential stuffing attacks. Managed service providers monitor multiple clients from a single platform. Penetration testers and red teams use our data to conduct realistic security assessments. Fortune 500 companies, MSSPs, and incident response teams rely on Breachsense for continuous dark web threat intelligence.
