Your credentials are already for sale. We find them before an attacker uses them.
A data breach is not the moment you are attacked. The attack comes later, when someone buys your leaked logins, clones your domain or sells access to your systems.

See where your exposure begins, and where we stop it.
A breach is rarely the attack itself. It is the raw material for one. The real damage happens later, in the days or months between your data appearing and someone using it. Almost all of that is time you could have used, if you had known.
From a forum post to a clean alert in your inbox.
Five phases, every one auditable. The work that turns underground noise into a single, actionable line your team can act on today.
We define what’s yours, in writing.
Domains, email patterns, brands, executive identities, repo namespaces, IP ranges, vendor IDs. The watchlist is the contract: exact strings, severities and exclusions, signed off before we collect anything.

Why teams start using this service.
What this service does that your existing stack does not.
We read these sources as attackers
We are ethical hackers and we spend most of our time on the offensive side, on red team and penetration testing engagements, so we read the underground the way the criminals buying your data do.
Verified and in context before it reaches you
We check a finding and put it in context before we alert, so what lands with you is what is worth acting on tonight.
Brand protection as a process
We run impersonation cases end to end: detection, prioritisation, and coordination of takedown and containment.
A layer, not a replacement
This complements your MFA, EDR, IAM and SIEM. Those controls watch what happens inside. This watches what is already circulating outside.
Your analysts never touch illicit environments
Investigation is carried out in a controlled way on your behalf, so no one on your team has to access underground sources to get the intelligence they need.
Every alert, owner and closure in one place.
For the service to be manageable, you need visibility and operational control, not a mailbox full of alerts. Everything lives in the Pentest Management Platform.
An operational service, not a feed of alerts.
Every case runs the same path, from the first signal to a documented closure.
- Watchlist agreed
- Exposure baseline
- Continuous monitoring
- Alerts with context

We at Etnia highly value our collaboration with Asperis Security. Their professionalism, approachability, quick response and ability to adapt to our needs have been key in every project. The quality of service and continuous support always give us peace of mind. Without a doubt, it is a pleasure to have them as technology partners.
At NPAW we have collaborated with Asperis on various security initiatives and the experience has been very positive. We especially value their ability to adapt to our needs and the depth with which they approach each project. Results are clear, structured and useful for decision-making and continuous security improvement. We like working with Asperis for the judgment and value they bring to every collaboration. Their work has helped us strengthen our security level.
ASPERIS has worked alongside us to define and implement our cybersecurity roadmap in Microsoft 365 with a structured approach aligned to business objectives. Thanks to their advice, we took the strategic step of completing our Microsoft ecosystem and reinforcing it with CrowdStrike for advanced mobile device protection, significantly raising our security level.
With Asperis you don’t hire a service. You hire a partner. They don’t look to bill a project. They look to establish a relationship of trust, caring about the key points that affect your organisation’s security. Professionalism, know-how and diligence.

Dark web monitoring is a continuous external-intelligence service that detects an organisation’s exposure across underground sources, leaked credentials, stolen data, sold system access and brand impersonation, and turns it into verified, prioritised alerts. Instead of counting mentions, it exists to shorten the time between an exposure appearing and your team containing it. Asperis delivers it as a managed service with follow-up to verifiable closure in the platform.
If your company’s credentials turn up on the dark web, the immediate risk is account takeover: someone logging into email, a cloud console or a remote-access tool as one of your employees, which is a common path to fraud, data theft and ransomware. The right response is fast and specific: reset and revoke the exposed accounts, check for logins you did not make, and watch for the same password being reused elsewhere. Our alerts tell you exactly which accounts are exposed and what to do first, and we track each one through to a verified closure.
It works by continuously watching deep and dark web sources, forums, marketplaces, leak repositories and infostealer feeds, for signals tied to your domains, brands and people, then validating each hit to remove noise and prioritising it by impact. You receive an alert with context and a recommended action, and we track the response through to a documented closure. Alerts are sent whenever relevant signal appears, and we consolidate periodic reports on trends and mitigation status.
A one-off breach scan is a snapshot of what has already leaked; dark web monitoring is a continuous service that alerts you the moment new exposure appears. The difference is timing, and timing is what decides whether you rotate a credential quietly or handle an incident. Monitoring also adds validation, prioritisation and closure, so you get decisions, not just a list.
We detect compromised credentials, sold access to corporate systems, leaked databases and documents, exposed source code and secrets, extortion and ransomware leak-site posts, and brand impersonation such as look-alike domains and phishing. No service has total visibility of the dark web, and we do not claim otherwise; the goal is maximum useful coverage and verified, actionable intelligence that reduces your exposure time.
Yes, brand impersonation is handled as a managed process, not a one-off notice: we detect the look-alike domain, phishing page or fake profile, prioritise it by risk, and coordinate takedown and containment, then track it to verifiable closure. Takedown timelines depend on the hosting provider and registrar, so we manage the case and keep you updated rather than promising a fixed turnaround.
No. Dark web monitoring is an external visibility layer that complements MFA, EDR, IAM and SIEM; it does not replace them. Its value is alerting you when exposure already exists outside your perimeter, or when early signals appear, so your internal controls and response are triggered before impact.
At minimum we need your corporate domains, your brands and products, and escalation contacts. From there we refine the watchlists, agree severities and set response playbooks during onboarding, and we run an initial baseline so you see prior exposure in the first week.
Cost depends on scope, the number of domains and brands to monitor, expected signal volume, reporting needs and level of support. We define a fixed proposal with a clear scope and delivery model, so there are no per-alert surprises. Book a short introductory meeting and we will size it to your environment.
Ready to cut the time between exposure and response?
Tell us your domains and brands. We will run a baseline, show you what is already out there, and set up monitoring that ends every case in a documented closure.
