Overt · External stack intelligence
Sales intelligence you can prove.

Your list was stale before you paid for it.
Technographic lists are sold quarterly and crawled even earlier. No row tells you where it came from, so your reps open conversations with claims they can't defend — and security buyers are exactly the people who check.
A list without sources isn't data. It's a rumor.
Every finding has a receipt.
This is what Overt knows about a company — and how it knows it. Sample data, real mechanics.

How it works
-
The corpus scans itself.
299,000+ Polish domains re-verify on a continuous cycle; every scanned profile is under 7 days old. No crawl-then-export.
-
Signals become scored plays.
Headers, DNS records, certificates and registries resolve into findings with confidence scores, then into account priority.
-
Your team works the list.
Plays, company financials, change alerts. Export CSV, call the API, or work from the Chrome extension.
Lists go stale. This doesn't.
Overt re-verifies its whole corpus continuously — and logs the day an account's stack genuinely changes. A dropped WAF, a new email-security vendor, a CDN migration: each one lands in the change feed and your webhook the day it's observed. You're not buying a snapshot; you're watching the market move.

Coverage where the spreadsheet vendors don't look.
Overt is built Poland-deep first, EU-wide next. Beyond the standard stack detection, it derives signals most data vendors don't attempt:
-
BGP-level DDoS posture
which organizations route through scrubbing providers, read from public routing data.
-
Buying-team geography
where the people who'd sign actually sit, versus the registered HQ.
-
Registry financials
revenue, headcount and legal form joined from the Polish national registry (KRS), on 52,000+ companies.
Works with the tools you already run.
CSV export that imports clean into any CRM REST API with an OpenAPI spec Chrome extension that scores any site your team visits Webhook alerts into Slack, Teams or Google Chat
What is Overt?
Overt is a sales-intelligence platform for cybersecurity resellers, MSSPs and vendor channel teams. It maps the security and technology stack of any company from public signals, scores the sales opportunity, and shows the evidence behind every finding. Its always-fresh corpus covers 299,000+ Polish companies and institutions, re-verified continuously.
We read what's public. And we show our work.
- Sources
- HTTP response headers, DNS records, certificate-transparency logs, public routing data, public registries.
- No intrusion
- Detection is passive. Active probing exists only as an authenticated, opt-in check for targets you're authorized to assess.
- Where it runs
- Cloudflare's network, with data stored in the EU.
- Paperwork

Questions buyers actually ask
Where does the data come from?
From what companies publish to the internet by operating there: response headers, DNS and email records, TLS certificates, routing announcements, and public registries like KRS. Nothing requires access to the target’s systems.
How accurate is it?
Accurate enough to show its work. Every finding carries the exact signal it was derived from and a confidence score; a CNAME match is treated differently from an HTML hint, and the score says so. When we’re not sure, you see that too.
Is this GDPR-safe?
Detection reads publicly observable infrastructure signals about companies, not individuals. Company records come from public registries. Contact enrichment inside the product uses licensed data providers. [A DPA and sub-processor list are available at signature.]
We sell outside Poland. Is Overt useful to us?
Honest answer: the always-fresh corpus is Polish today, and that depth is the point. Any domain worldwide can be scanned on demand with the same evidence model. The corpus expands EU-wards with early-access partners.
How is this different from BuiltWith or Wappalyzer?
They profile technologies. Overt is built for one buyer: security sellers. It scores accounts into displacement plays, attaches the evidence, joins company financials, and alerts on change — the work between “what they run” and “what you say in the first email.”
What does it cost?
Pricing is being set with founding customers, and we’ll state it plainly on the call — no quote theater. Early-access teams get founding terms.
What happens on the live scan?
You bring 10–20 accounts you actually work. We run Overt on them live and walk through the findings, plays and evidence together. If the data doesn’t earn the next meeting, that’s a useful answer too.
