Compromised Credential Monitoring

Powered by Sonar, our AI-powered credential intelligence engine. We continuously surface your organisation's compromised credentials across the surface, deep, and dark web, validate which ones still authenticate, and deliver the cleartext evidence and context you need to act before attackers do.

§ Service Overview

Your employees' credentials are already leaking. We find them before attackers use them.

Continuous monitoring of compromised credential exposure across the surface, deep, and dark web, with the validation and context needed to act on what we find.

Credential theft is the most common path attackers take into modern organisations. Every day, employee passwords surface in public breach datasets, infostealer log markets, dark web forums, Telegram channels, paste sites, and combo lists. Most of these exposures are never detected by the organisations they affect until an attacker has already used them.

Compromised Credential Monitoring is built on Sonar (formerly Credenshow), our proprietary AI-powered credential intelligence engine. Sonar continuously collects and processes credential exposure data from across the surface, deep, and dark web, with a private dataset prioritised for Asia and Hong Kong sources that global providers under-index.

Each engagement is led by senior consultants who interpret what Sonar surfaces. We validate which credentials still authenticate against your environment, deliver the cleartext evidence and context required for response, and provide real-time alerts as new exposures appear. The result is intelligence your team can act on, not raw lookup output.

§ The Sonar Engine

Continuous credential intelligence, built in-house.

Sonar is the proprietary engine that powers our Compromised Credential Monitoring service. Built and operated in-house, it continuously collects and processes credential exposure data across global and Asia-focused sources, with active validation and senior consultant interpretation layered on top.

AI-Powered Continuous Collection

Sonar continuously ingests credential exposure data across the surface, deep, and dark web, automatically parsing, classifying, and deduplicating findings. The engine runs around the clock, not on scheduled refresh cycles.

Private Asia-Focused Dataset

Sonar maintains its own collection infrastructure prioritised for Hong Kong and broader Asia sources that global credential intelligence providers under-index. The result is visibility into regional exposure that competitors built on US and EU data feeds cannot match.

Active Credential Validation

Every flagged credential is tested to determine whether it still authenticates against your environment. Testing is performed with your authorization, non-disruptively. You receive verified intelligence on which exposures represent live risk, not just historical leaks.

Full Cleartext Disclosure

Most providers return exposure status only or partial hints. Sonar delivers the full cleartext credentials we recover, so your team can verify the exposure, identify password reuse patterns, and protect against the credential reuse attacks that drive most modern account takeovers.

Real-Time Alerting

As new exposures surface, alerts are delivered through your agreed channel with the full context required to triage and respond. No waiting for monthly reports.

Expert Review & Response Context

Every finding is reviewed by a senior consultant before delivery. We filter noise, prioritise by exploitability and business context, and pair findings with recommended response actions. You receive operationally useful intelligence, not raw feed output.

§ Our Competitive Advantage

How Sonar compares to other credential monitoring providers.

Five differences that determine whether your monitoring catches the exposures that actually matter.

Other Credential Monitoring Providers
Sonar by Next Security
Exposure status only. Returns yes/no indicators or partial hints, leaving you to guess which exposures are real and what password actually leaked.
Full cleartext credentials disclosed. The actual recovered credential is delivered to your team, enabling verification, password reuse defence, and immediate response action.
Reports historical exposure. Findings tell you a credential leaked at some point, leaving your team to guess which ones still work and which have already been rotated.
Active Credential Validation. Each flagged credential is tested against your environment to confirm whether it still authenticates, delivering verified live risk rather than historical noise.
Global datasets primarily US and EU. Coverage built on third-party feeds that under-index Hong Kong and broader Asia sources, missing regional exposure relevant to your environment.
Private Asia-focused dataset, Hong Kong prioritised. Proprietary collection infrastructure built for regional exposure that global providers cannot reach.
Surface web and known leak datasets. Coverage misses the infostealer log ecosystems and dark-distribution channels behind most modern account takeovers.
Surface, deep, and dark web coverage. Continuous collection across infostealer log markets, dark web forums, Telegram channels, paste sites, and combo lists, where credentials actually trade today.
Periodic refreshes from third-party feeds. Findings arrive in batches with detection delays measured in days or weeks, often too late to act on.
AI-powered engine, continuous in real time. Sonar collects and processes around the clock, with alerts delivered as exposures surface.
§ Coverage

Where Sonar looks for your exposed credentials.

Continuous collection across every source category that matters to modern credential exposure, with private datasets focused on Asia and Hong Kong sources global providers under-index.

01

Public Breach Datasets

Credential dumps from publicly disclosed corporate breaches, ingested as they surface across breach-tracking communities, leak repositories, and underground markets.

02

Infostealer Log Markets

Logs from established infostealer malware families, traded across dark web markets and successor platforms. The single largest source of fresh corporate credentials today.

03

Dark Web Forums & Marketplaces

Active and historical monitoring of dark web forums and credential marketplaces where leaked datasets, fresh dumps, and compromised access are traded.

04

Telegram Channels

Public and private Telegram channels and chats that have become a dominant distribution layer for infostealer logs and freshly compromised credential dumps.

05

Paste Sites & Code Repositories

Pastebin, Ghostbin, GitHub commits, and other public sites where credentials are deliberately leaked or accidentally exposed by developers.

06

Combo Lists

Aggregated credential dumps assembled from multiple sources and traded standalone, often the basis for credential stuffing campaigns.

07

Surface Web Leaks

Misconfigured cloud storage, exposed databases, leaked documents, and other surface-web exposures discovered through continuous monitoring of public infrastructure.

Sonar Advantage

Private Asia-Focused Dataset

Beyond what global providers cover, Sonar maintains proprietary collection infrastructure prioritised for Hong Kong and broader Asia sources. The result is visibility into regional exposure that competitors built on US and EU data feeds cannot match.

§ Why Choose Next Security

The Next Security Advantage

Beyond Sonar's intelligence engine, here's what backs every finding we surface and every recommendation we make.

§ Methodology

A five-phase engagement framework.

A structured approach that turns continuous exposure intelligence into operational defence, with clear responsibilities on both sides.

01
Scoping

Scope & Engagement Setup

Define monitored identities, domains, executive targets, alert channels, escalation contacts, and response protocols. Confirm authority and agree the rules of engagement for Active Credential Validation.

02
Discovery

Initial Exposure Scan

Comprehensive baseline scan of all existing exposures across your domains and identities. Recovered credentials are validated, classified by severity, and delivered as the onboarding findings report.

03
Monitoring

Continuous Collection & Detection

Sonar continuously ingests new exposure data across the surface, deep, and dark web. New findings affecting your nominated identities are extracted, deduplicated, and queued for validation.

04
Validation

Active Testing & Senior Review

Each new finding is tested to determine whether the credential still authenticates against your environment, then reviewed by a senior consultant who filters noise, prioritises by exploitability, and pairs findings with response context.

05
Reporting

Alerts, Quarterly Reviews & Response Support

Validated findings are delivered through your agreed alert channel. Quarterly executive reviews cover trends, validated risk, and recommended actions. Senior consultants remain available for response support throughout the engagement.

§ Frequently Asked Questions

Answers to questions we hear most during scoping.

How does this differ from free tools like Have I Been Pwned?

Free lookup tools check known public breach datasets and return exposure status only. Sonar continuously collects across public breach data plus infostealer log markets, dark web forums, Telegram channels, paste sites, and private Asia-focused sources that public tools cannot reach. Every finding is delivered in cleartext, validated against your environment to confirm whether the credential still authenticates, and reviewed by a senior consultant before delivery.

How does Sonar collect credential data?

Sonar is our proprietary AI-powered collection engine, continuously ingesting credential exposure data across the source categories detailed in our Coverage section, spanning surface, deep, and dark web. The engine operates around the clock rather than on scheduled refresh cycles, automatically processing and validating findings before they reach your team.

What is Active Credential Validation and how is it performed?

Every flagged credential is tested to determine whether it still authenticates against your environment, with the goal of separating live risk from historical leaks that have already been rotated.

Validation is performed under explicit written authorization, against the identity surfaces agreed during scoping. Validation attempts are throttled below your authentication lockout thresholds, sourced from IP addresses whitelisted in advance, and timed to an agreed validation window. Where you operate a SOC, SIEM, or active monitoring tooling, we share validation source IPs, timing, and signatures in advance so resulting events can be correctly attributed rather than triaged as live incidents.

Where MFA is enforced on the identity surface being tested, validation confirms whether the password component still authenticates. Full operational exploitability of a leaked credential in your environment depends on your broader authentication stack including MFA, Conditional Access, and device trust policies, and is contextualised in this light during senior consultant review.

How are alerts delivered and how quickly?

Alerts are delivered through your agreed channel, typically secure email or a per-client confirmed means established during onboarding. As new findings surface in Sonar's collection pipeline they are validated, reviewed by a senior consultant, and delivered with full context as soon as review is complete.

How do you handle PDPO compliance and prevent misuse of the service?

Compromised credential monitoring necessarily involves processing identity data. Our engagement model is built around explicit client authorization, KYC verification, and contractually-defined data handling. As part of KYC, we verify each client's legitimacy and confirm the service is engaged to monitor their own organisation's identities, not as a tool for unauthorized lookup against third parties. Cleartext findings are delivered securely and only to the legitimate identity owner, with encrypted transport, access-controlled storage, and agreed retention and destruction terms.

What happens if a credential is found but my employee has already changed their password?

Active Credential Validation surfaces exactly this distinction. Where the validation result confirms the credential no longer authenticates, the finding is delivered with that context, allowing you to deprioritise it. Validation removes the guesswork of treating every historical exposure as live risk.

How do you reduce false positives?

False-positive reduction is built into Sonar's collection pipeline through automated deduplication, source quality classification, and AI-powered filtering, and reinforced by senior consultant review of every finding before delivery. The combination eliminates duplicated dumps, synthetic data, low-credibility sources, and findings that do not apply to your environment.

How long does onboarding take?

Onboarding typically completes within 1 to 2 weeks of scoping sign-off. The initial exposure scan runs during this period and the onboarding findings report is delivered at the end of week 2. Continuous monitoring begins immediately after onboarding closes.

Can we engage you for a one-time lookup rather than ongoing monitoring?

Yes. Our Targeted Lookup mode delivers a one-time credential intelligence scan across your domains and nominated identities, with active validation of recovered credentials and a delivered findings report. Many clients use Targeted Lookup as an entry point and convert to Continuous Monitoring afterwards.

How is this different from password compromise checks built into Microsoft Entra ID or our identity provider?

Identity provider checks compare submitted passwords against known compromised password lists at password-set time, which is valuable but narrow in scope. They do not surface when your employees' corporate identities are exposed in third-party SaaS breaches, in infostealer logs harvested from infected endpoints, or in credential dumps that never enter mainstream leak datasets. They also do not validate whether an exposed credential still works against your environment. Sonar covers the broader credential exposure surface and confirms live risk through Active Credential Validation.

Do you provide a Letter of Attestation?

Yes. On request, we issue a formal Letter of Attestation summarising the engagement scope, monitoring period, methodology followed, and high-level outcome. The attestation is suitable for audit, regulatory submission, and third-party assurance purposes including HKMA C-RAF, ISO/IEC 27001, SOC 2, and similar obligations.
