About Flare

Flare sells software that finds compromised identities across people, machines, and AI agents. Flare matches stealer logs, leaked credentials and live session cookies to employees and contractors, then revokes their access through the customer's identity provider automatically. Flare finds customers' stolen session cookies and credentials so that sessions can be reset and a fresh login forced before fraud starts. Flare watches for API keys issued by one provider, wherever they leak, so the provider can reset them before anyone abuses them. Flare surfaces every API key, token and service account in its data that is tied to a customer company, so the customer can revoke it before an attacker or a rogue agent uses it.[1]

Flare pulls indicators and techniques from dark web forums, Telegram and ransomware chatter, maps them to MITRE ATT&CK, and pushes them to a customer's SIEM. Flare delivers fresh IOCs and mapped TTPs into a SIEM, SOAR or TIP over STIX/TAXII. Threat Flow agents read dark web forum chatter, cross-check sources and write finished intelligence with confidence levels and citations. Flare writes threat briefings on the actors, campaigns and exposures that matter to a customer's sector, written for executives and backed by Flare's research team.[1]

Flare watches the forums where access, data and tools are sold, and alerts a customer when its company, vendors or executives come up. Flare tracks ransomware leak sites and alerts a customer when a vendor or partner is listed. Flare tracked over 6000 ransomware breaches in 2024. Flare automatically scans the dark, deep, and clear web for an organization's leaked data, whether it be technical data, source code, leaked credentials or secrets. Flare automatically monitors for secrets and alerts a security team to an accidental commit.[3][4]

Flare scans the clear and dark web 24/7 to detect risks like lookalike domains, leaked code and exposed cloud storage. Flare detects lookalike domains and phishing infrastructure early, and identifies applications across third-party app stores. Flare is used by Fortune 50 organizations to stop sensitive data leaks in public GitHub repos. Flare data can be brought into existing intel and case management systems, including SIEM, SOAR, Slack, Jira, and Splunk. Flare automates remediation of compromised credentials through Entra ID. Flare states that its continuous monitoring supports HIPAA Security Rule, Business Associate and Breach Notification obligations, with a documented audit trail built for OCR investigators and compliance reviews.[3][6]

Flare covers the criminal markets where EHR credentials, clinical and financial application access, and API keys are bought and sold. Flare monitors vendor domains across criminal markets so that third-party exposure surfaces before a breach notification letter. Flare surfaces exposed government data across dark web forums, Telegram channels, and stealer logs. Flare taps into underground chatter and tools used by criminal networks to support investigations. Flare finds leaked credentials and session tokens so that access can be cut off before attackers use them. Flare identifies impersonation infrastructure before it reaches customers.[6][7][8]

Flare detects leaked developer logins and tokens across GitHub, paste sites, and stealer logs. Flare detects compromised enterprise credentials early and enables automated remediation.
