Lunar by Webz.io prevents the unauthorized use of stolen or compromised credentials from accessing your environment. This enables CIOs, CTOs, and security leaders a direct view into where user passwords are being sold, exchanged, and prepared for abuse across the dark web and other underground channels.
This is an invaluable capability in a world where attackers increasingly prefer using valid credentials to zero-day exploits. Stolen credentials from infostealers and data breaches circulate throughout marketplaces, private channels, and stealer logs, before returning as account takeovers (ATOs), business email compromises (BECs), and fraud campaigns. Traditional defenses such as MFA and conditional access are helpful, but reactive if you don’t know what credentials have already been exposed. They can also be bypassed entirely.
The new landscape of credential-driven attacks
Today, many intrusions begin with a working username and password rather than a zero-day. Infostealer software and keyloggers silently intercept browser-saved passwords, session cookies, and device fingerprints and package them together in logs for sale or sharing among malicious actors. The same records can be collected and repackaged into combo lists and passed around on dark web forums, online marketplaces, and encrypted messaging channels to help fuel ATO, BEC, and fraud on a large scale.
Even enterprises with mature security programs are frequently slow to hear about this happening. Lacking systematic access to breached and traded credentials associated with your domains and identity, SOC personnel are left to play defense by waiting on things like fraud alerts and third-party notifications to suggest things have gone off the rails. Proper mitigation then depends on discovering the exposed credential before it’s used in an incident on your production systems. That is the exact gap Lunar was designed to close.
What is Lunar by Webz.io?
Lunar is a SaaS software which converts Webz.io’s massive open, deep, and dark web data collection into operational intelligence for compromised data and credentials. It continuously monitors high-risk sources, including dark web forums, marketplaces, stealer logs, leak sites, and other underground channels to root out exposures that are directly tied to your organization.
Lunar correlates underground records with corporate domains, email patterns, and identity markers to distinguish between generic leaks and exposures involving employees, executives, customers, and partners. It acts as a dedicated dark web intelligence layer that produces high-value, identity-aware signals that can be fed into existing security stacks and processes.
Core Lunar capabilities
Lunar’s core capabilities meet the challenges security leaders face with credential exposure and external risk. These capabilities include:
Breached credential monitoring and ATO disruption:
Lunar continuously monitors credentials associated with your domains, SaaS applications and internet-connected devices, surfacing them the moment they appear in a stealer log, dump or underground market. This allows teams to trigger resets, fine tune access controls or trigger step-up authentication before an attacker logs in.
Identity and executive protection:
Lunar monitors high impact personas, including executives, administrators, and finance officers, who are often targeted in attacks. The moment their credentials or sensitive data are found in underground channels, Lunar generates targeted alerts so your team can act quickly and treat those accounts with the urgency required.
Third-party and supply-chain visibility:
Lunar monitors mentions and exposures from strategic suppliers, partners and customer organizations, revealing when third-party breaches pose a risk to your environment. This supports vendor risk management programs with concrete, external intelligence instead of relying solely on questionnaires and self-attestations.
Support for MSSPs and security providers:
For MSSPs, MDRs, and consultancies, Lunar comes with packaging & multi-tenant capabilities for managed dark web monitoring, exposed-credential alerting & breach detection. These organizations can layer their own playbooks and reporting on top of Lunar’s intelligence to deliver unique offerings to their clients.
Strategic results for technology and security chiefs
The benefits of a breached-credential and dark web intelligence platform go beyond adding new detection rules. It provides a proactive operating model for clearer risk and governance narratives.
Affect operation and analyst efficiency:
Lunar’s correlation and risk scoring reduce noise by focusing on exposures tied to your identities and critical systems, freeing SOC teams to focus on impactful work instead of tasks like manually searching dark web forums and leak sites.
Reduced likelihood of successful attacks:
Early detection of exposed credentials limits the time attackers have to launch an attack. Even when other controls are bypassed or misconfigured, quickly removing high-risk accounts can significantly reduce attacker dwell time and the probability of a major incident.
Board and regulator visibility:
Boards and regulators are increasingly demanding organizations showcase active monitoring of external threat surfaces, including the dark web. Lunar helps formalize this into a repeatable, auditable practice, allowing CIOs, CTOs, and CISOs to follow through on evidence of proactive controls and, at a minimum, see more meaningful data to back up risk reporting.
How Lunar works with your existing stack
Exposed-credential events can also be pushed into identity and access management systems and ticketing/ITSM solutions to drive forced resets, conditional changes to access, and tracked remediation tasks with easy ownership. Because Lunar focuses on external and underground activity rather than internal telemetry, it fills a visibility gap your existing infrastructure, endpoint, and email tools were never designed to cover.
Lunar is built to integrate with your existing tool. Its alerts and enriched context can feed into SIEM and SOAR platforms, where they correlate with authentication logs, endpoint telemetry, and network data to create richer detections and automated response workflows.
If your organisation is prepared to transition from reactive breach response to proactive credential and dark web defense, now is the time to see what Lunar can add to your security strategy.
