Certigna SASU is the RIPE registry identity for Certigna, a French Tessi subsidiary providing ANSSI-eIDAS qualified trust services (signatures, seals, timestamping) and operating AS210832 with three /24 prefixes. The thesis is that its dual internet/regulatory surface makes routing and qualification changes materially consequential for dependency mapping. Evidence is limited to public RDAP, IPinfo, company, INSEE, and ANSSI sources; no revenue model, customer data, or live BGP is available. Watchpoints include registry record changes, prefix movements, ANSSI qualification decisions, and Tessi parent restructuring.

Certigna SASU

Certigna SASU is the public RIPE registry identity behind AS210832, a French digital-trust provider that delivers ANSSI-eIDAS qualified electronic signatures, seals, and timestamping. It announces three IPv4 /24 ranges with upstream connectivity to SFR and Eurofiber France, operates as a subsidiary of the Tessi group, and holds regulatory qualifications that give its trust services legal standing under EU law.

Why It Matters

A loss of ANSSI qualification would strip the legal value of issued certificates, potentially freezing workflows in banking, legal, and public-sector applications. Routing disruptions could similarly break connectivity to certificate validation endpoints and hosted signing platforms, cascading into compliance and availability failures for customers that depend on Certigna’s trust services.

What Public Sources Show

Certigna SASU is the public registry face of a French digital-trust firm that blends internet routing with regulated identity services. As the holder of ANSSI-eIDAS qualified status, it enables legally recognized electronic signatures, seals, and timestamps for business and government users. Its AS210832 routing footprint and reliance on upstream carriers make it a concrete dependency for any service that invokes its certificates or hosted trust applications.

Changes in its regulatory standing or network posture therefore carry operational consequences for a broad customer chain.

Public records confirm Certigna SASU is registered with SIREN 481 463 081 as a SAS headquartered in Villeneuve d’Ascq, with capital of €276 485. RIPE RDAP data links the entity to AS210832, allocated in August 2021. IPinfo attributes three IPv4 /24 ranges—91.199.221.0/24, 185.149.14.0/24, and 185.149.15.0/24—to that ASN, listing SFR (AS15557) and Eurofiber France (AS35625) as upstream peers.

ANSSI decision 1827 and the agency’s qualified‑services catalogue explicitly name Certigna and grant eIDAS qualification for document‑signing and electronic‑seal certificate services through November 2027.

The company operates two distinct but interdependent surfaces. The network surface comprises AS210832 with three advertised IPv4 blocks and upstream connections to SFR and Eurofiber, providing the transport for its hosting and timestamping services. The regulatory surface encompasses its RGS and eIDAS qualifications, issued by ANSSI, which entitle Certigna to offer qualified electronic signatures and seals that carry legal presumption under EU law.

Certigna’s own website describes a broader product suite including authentication, cryptography, SSL encryption, probative storage, and hosting.

Because Certigna’s trust services are legally recognized, any interruption to its network visibility or qualification status can cascade into the compliance posture of its customers. A sudden withdrawal of ANSSI qualification would strip the legal value of issued certificates, potentially freezing workflows in banking, legal, and public‑sector applications that depend on them.

Similarly, routing changes—if AS210832 were to lose upstream connectivity or if its prefixes were hijacked—could disrupt the availability of certificate validation endpoints and hosted signing platforms.

Several observable events could change the risk picture. First, any alteration in RDAP, WHOIS, or RIPE registry records for AS210832 or ORG‑CS706‑RIPE would signal a shift in control or ownership. Second, the appearance or disappearance of prefixes advertised by AS210832—especially if confirmed by live BGP feeds—would reshape the infrastructure footprint. Third, any ANSSI decision to renew, suspend, or withdraw the eIDAS qualification directly impacts regulatory standing.

Finally, a divestiture or material restructuring of the Tessi parent group could affect financial and operational continuity.

The current picture is limited to public‑source evidence. The three IPv4 prefixes are known through IPinfo, not verified by live BGP observation; future routing data would strengthen claims about active announcements. The profile does not establish Certigna’s revenue model, customer concentration, certificate‑issuance volumes, or internal service topology.

The naming variance between “Certigna SASU” in RDAP and “CERTIGNA” in French company registers is a legal‑form convention, not an indication of separate entities.

Operating Surface

Certigna SASU operates as the RIPE-facing registry identity for Certigna, a company that delivers qualified electronic signatures, seals, timestamping, and hosting services. It holds eIDAS qualifications published by ANSSI and runs autonomous system AS210832, announcing three IPv4 /24 ranges, with upstream connections to SFR and Eurofiber France. Its dual regulatory and network surface makes it a consequential node for trust-dependent businesses.

Certigna matters operationally because it combines a public internet routing footprint with regulated digital-trust services. Changes to AS210832 routing, prefixes, upstreams, or RIR records can affect visibility of Certigna-operated infrastructure, while changes to ANSSI/eIDAS qualification status can affect the trust basis for certificates, signatures, seals, timestamps, and related customer workflows.

Watchpoints

Certigna’s value as an intelligence subject derives from the coupling of a modest but observable internet routing footprint with legally significant trust-service qualifications. Disruption in either surface can cascade into customer compliance or service-availability incidents. The fragmented public evidence (RDAP vs. French registry name, absence of live BGP) means the profile should be treated as a baseline that strengthens when confirmed by routing data and corporate-filings links.

1. Any change in AS210832 registry records or routing announcements (especially if verified by live BGP). 2) ANSSI decisions that renew, suspend, or withdraw eIDAS qualification before November 2027. 3) Corporate actions by parent Tessi that could alter financial or operational backing. 4) Emergence of new downstream relationships or IPv6 allocations that would expand the infrastructure surface.

Live BGP confirmation of the three /24 prefixes is absent; IPinfo snapshot provides static attribution. No revenue segmentation, customer lists, or certificate-issuance volumes are available from public sources. The precise legal link between the RIPE organization handle ORG-CS706-RIPE and the French SIREN entity should be cross-verified with RIPE organization records.
