0DaySecure
Private beta — onboarding design partners

Find what an attacker finds, before they use it.

0DaySecure watches the open internet and the criminal underground for anything that names your organisation: credentials for sale, internet-facing hosts nobody logged, domains built to impersonate you. Three modules, one prioritised feed.

The gap

Three questions you cannot answer from inside the perimeter.

Your SIEM watches your network. None of these live on it.

  • 01

    “Is our data already being traded?”

    Credential dumps circulate for months before anyone notices. Your logs record a successful login, not a purchased one.

  • 02

    “What of ours is exposed to the internet?”

    An asset inventory describes what was built on purpose. Attackers find what was left behind — a staging host, a test API, a subdomain still pointing at a cloud account someone closed.

  • 03

    “Who is pretending to be us?”

    A domain that looks like yours costs a few pounds and takes ten minutes to stand up. Your customers and your staff meet it before you do.

One platform, three modules

Collection, correlation and response for everything outside your firewall.

Buy the module that hurts most today. The others switch on against the same asset inventory, so nothing has to be set up twice.

  • Module 01

    Dark Web Monitoring

    We watch the marketplaces, forums, paste sites, ransomware leak pages and closed channels where stolen corporate data surfaces first — and tell you when yours appears.

    • Leaked employee and customer credentials, with the breach they came from
    • Ransomware leak-site listings naming your organisation or your suppliers
    • Access brokers advertising a route into your network
    • Source code, documents and database dumps offered for sale
    Collection
    Tor, I2P, forums, paste sites, Telegram

    Attack Surface Management

    Starting from nothing but your domain name, we map what you actually have facing the internet — then keep mapping it, because it changes every week without anyone filing a ticket.

    • Subdomains, IP ranges, certificates and cloud services attributed to you
    • Forgotten staging hosts, expired certificates and orphaned DNS records
    • Exposed admin panels, databases, storage buckets and remote access
    • Change tracking, so a new exposure is flagged the day it appears

    Brand Protection

    Impersonation is the cheapest attack there is. We find the lookalike domains, phishing pages, fake apps and fraudulent accounts using your name, and get them removed.

    • Typosquat, homoglyph and combosquat domain registrations, from day one
    • Live phishing pages cloning your login screens, with evidence captured
    • Counterfeit mobile apps and impersonation accounts on social platforms
    • Managed takedowns filed and chased to closure on your behalf

    Illustrative timeline

How it works

Four steps. No agent, no appliance.

Onboarding is deliberately dull. You hand over a domain; we do the collection; you get a feed you can act on.

  1. Step 01

    Connect

    Give us a domain name. Add the brands, executive names and supplier domains you want watched. Nothing to install, no network access, no code.

    One domain name to start

  2. Step 02

    Discover

    We map what you have facing the internet and start collecting from underground markets and forums, certificate transparency logs, app stores and domain registries.

    Passive collection, then continuous

  3. Step 03

    Correlate

    Findings are de-duplicated across the three modules, attributed to an owner, and scored on whether an attacker could reach them today.

    Continuous, not a quarterly report

  4. Step 04

    Act

    Alerts are built to arrive in the tools your team already uses, each with the evidence attached and a recommended fix. Takedowns we file and chase ourselves.

    Jira, Slack, SIEM or webhook — roadmap

Why one platform

Three signals. One conclusion.

A leaked password is an inconvenience. A leaked password for a VPN portal you did not know was still online is an incident. A tool that sees only one of those cannot tell the difference.

  • Dark web

    credential pair on sale · 4d old

  • Attack surface

    VPN portal live · not in the CMDB

  • Brand

    phishing page cloning that portal

Criticalone correlated finding

Exploitable path into the corporate network

A valid credential pair, a forgotten SSL-VPN portal that answers on the public internet, and a page harvesting logins for it. On its own, not one of the three would be ranked critical.

  • +DARK WEB — credential pair on sale · 4d old
  • +ATTACK SURFACE — VPN portal live · not in the CMDB
  • +BRAND — phishing page cloning that portal

Illustrative example

  • De-duplicated across modules

    One host, one domain, one credential — counted once, however many collectors saw it. Three tools give you three tickets for the same problem.

  • Scored on reachability

    Priority reflects whether an attacker could use it today: is the host answering, is MFA enforced, is the password still valid. Not a raw CVSS number.

  • One owner, one ticket

    A correlated finding is routed to the team that can actually close it, with the evidence and the recommended fix already attached.

Specimen

What a finding actually looks like.

We have no customers to quote yet, so here is the work instead. Every alert arrives in this shape: what we found, where we found it, why it matters, and what to do about it.

HighFND-4127 · brand protectionIllustrative example

Lookalike domain hosting a clone of your employee sign-in page

acme-sso.example

What we found

A domain registered two days ago behind privacy protection, serving a pixel copy of your employee sign-in page over a valid certificate. The login form posts to an endpoint the attacker controls, then redirects to your real portal so the visitor sees a normal second attempt.

Where we found it

A certificate transparency log entry matched your brand watchlist. We resolved the host, fetched the page, and stored the screenshot, the DOM, the WHOIS record and the TLS chain as evidence before the site could change.

Why it matters

Credentials typed here reach an attacker in seconds. Because the domain and its certificate are hours old, your mail gateway has no reputation signal to block on, and your staff have nothing visual to distinguish it from the real portal.

What we recommend

Block the domain at the mail gateway and egress now. We file the takedown with the registrar and the hosting provider in parallel and chase it to closure. Add the registration pattern to the watchlist so the next variant is caught on the day it appears rather than on the day it is used.

Integrations

Findings go where your team already works.

An alert nobody sees is not an alert. Push findings into your tracker, your chat and your SIEM, or pull them with the API.

  • Ticketing

    • Jira
    • ServiceNow

    A finding becomes an issue in the project you nominate, with the evidence attached.

  • Chat and alerting

    • Slack
    • Microsoft Teams
    • Email

    Route by severity or by module, so a critical wakes someone and a medium does not.

  • SIEM and analytics

    • Splunk
    • Microsoft Sentinel

    External findings land next to your internal telemetry for correlation and reporting.

  • Build your own

    • Webhooks
    • REST API
    • CSV export

    Signed webhooks on every state change, and a documented API for everything else.

Planned for general availability · These are the integrations on the roadmap, not a list of shipped connectors. If the one you need is missing, say so during the beta and we will weigh it against the rest.

See your own exposure first.

A demo on your domains, not a canned dataset. Thirty minutes, and you keep the findings either way.
