The advantages

Aleph makes visible what escapes everyone else

Four technical differences, and what they change for your teams.

Read our legal framework

  1. 01Unmatched history

    Since 2012, without a single gap

    • Our dark web index has been built continuously since 2012.
    • That depth in time rebuilds the full history of a leak and surfaces dormant threats, where point-in-time scanners see nothing.

    You reach the archives back to 2012 instantly, to qualify where a threat comes from and how it evolves.

  2. 02Investigation depth

    Nine levels below the surface

    • Our algorithms explore the relational environment of suspicious sites down to nine levels deep.
    • The engine extracts and indexes raw data inside the files themselves: HTML, PDF, text documents, spreadsheets, ZIP archives.
    • 550 million URLs crawled, two billion email addresses recovered from leaks.

    You clear the blind spots in your attack surface by mapping every exposed document and credential.

  3. 03Legality & GDPR compliance

    Investigate without ever leaving the law

    • Aleph Search and Aleph Alert are built on a passive indexing process, protected by patent FR3000253.
    • Unlike offensive tools, our crawlers only reach public data and never bypass a security barrier.
    • Native data-minimisation filters keep collection compliant with the GDPR and keep your investigations clear of any handling offence.

    You watch your cyber risk on solid legal ground, with no exposure to regulatory or criminal penalties.

  4. 04Technological sovereignty

    French from collection to hosting

    • The technology is designed, developed and maintained in France, by a company with 100% French capital.
    • Every piece of collected data is hosted on French soil, beyond the reach of extraterritorial law.

    You get a sovereign partner to meet NIS 2 and DORA requirements end to end.

Use cases

What the regulation requires of you

This is not a security option. It is an obligation, in three texts.

DORA, NIS2 and the GDPR never name the dark web. They require something else: detect anomalous activity, gather threat intelligence, monitor your providers, test how effective your measures are. Nine obligations, and a dark web index answers all four.
