Qualified trust service providers in Ireland: who the eIDAS providers are
A qualified electronic signature is the only kind that carries the legal weight of a wet-ink signature across the whole EU. That status does not come from software; it comes from a qualified trust service provider on a national Trusted List. As of 2026-07-05T07:00:59.632Z, 5 trust service providers are established in Ireland, and between them they cover qualified certificates, qualified timestamps and qualified long-term preservation. This is the definitive Irish reference to who they are and what each one is qualified to do.

The short version for an Irish operator
If you sign documents electronically, eIDAS, the EU regulation behind every legal e-signature, sorts them into three levels: simple, advanced and qualified. Most everyday e-signature software produces simple or advanced signatures. Only a qualified signature has the equivalent legal effect of a handwritten one across the EU, and the reason it does is the qualified certificate behind it.
That certificate has to come from a qualified trust service provider on an EU member-state Trusted List. Ireland publishes its own list. Right now it holds 5 providers, of which 2 can issue the qualified certificates that sit under a qualified signature or seal, 3 offer qualified timestamps, and 1 offers qualified long-term preservation. An Irish business is not limited to this list: a qualified provider in any member state works just as well, because qualified status is EU-wide.
How the eIDAS framework works: three signature levels
Every legal e-signature in the EU is one of these three levels, defined in Regulation (EU) No 910/2014 (eIDAS). The further up you go, the less you have to prove if a signature is challenged. The bar shows relative evidential weight, not a measured value.
Simple electronic signature
Any data in electronic form used to sign: a typed name, a tick box, a scanned signature, an email sign-off.
Cannot be denied legal effect simply for being electronic, but the person relying on it carries the burden of proving who signed and that nothing changed.
Advanced electronic signature
Uniquely linked to the signatory, capable of identifying them, created using data under their sole control, and tamper-evident after signing.
Stronger evidential position. The signatory is identifiable and any change to the document after signing is detectable.
Qualified electronic signature
An advanced signature created by a qualified signature creation device and based on a qualified certificate from a provider on an EU member-state Trusted List.
The only level with the equivalent legal effect of a handwritten signature across the entire EU. A QES recognised in one member state must be recognised in all the others.
The jump that matters is from advanced to qualified. An advanced signature is strong evidence; a qualified signature is treated as equivalent to a handwritten one across the EU and shifts the practical burden onto anyone who wants to dispute it. The thing that makes a signature qualified is the qualified certificate from a supervised provider, which is where the Trusted List comes in.
What "qualified" actually means, and the Trusted List system
Qualified is not a label a provider can give itself. Under eIDAS, a trust service is qualified only if the provider holds qualified status and appears on a national Trusted List maintained by a member state's supervisory function. Ireland publishes its Trusted List through eidas.gov.ie. That list is what we parsed for this page.
Every member state's Trusted List is in turn linked from a single EU index, the List of Trusted Lists (LOTL), hosted by the European Commission. The LOTL is what makes qualified status portable: a signature created with a qualified certificate from, say, a German or Italian provider can be traced back through that country's Trusted List to the same EU-level register that anchors the Irish one. This is why an Irish business can rely on a qualified provider from any member state, not only the ones established here.
A qualified electronic signature created in one EU member state must be recognised as a qualified electronic signature in every other member state.
The 5 trust providers established in Ireland
These are the trust service providers established in Ireland on the national Trusted List as of 2026-07-05T07:00:59.632Z, with the qualified services each one is listed for. The tick row at the top of each card shows coverage at a glance: certificates (the signature and seal tier), timestamps, and long-term preservation.
Adobe Systems Software Ireland Ltd.
GrantedEstablished in Ireland
- Adobe Qualified Timestamp CA
Listed for qualified timestamps only, not qualified certificates. Relevant where documents are processed through Adobe tooling and an Ireland-supervised qualified timestamp is needed.

- Entaksi Qualified Time Stamp Authority Service
- Entaksi Qualified Certification Authority for eSignatures
- Entaksi Qualified Certification Authority for eSeals
The only Ireland-listed provider offering qualified long-term preservation, the service that keeps a signed or sealed record legally valid for years (contracts, archives, regulated records).

An Post subsidiary. Carries a qualified certificate service with a status of under supervision on the Trusted List, distinct from the granted status of the other four. Check the live list before relying on it for a specific transaction.
TrustPro QTSP Ltd
GrantedEstablished in Ireland
- TrustPro Qualified CA 1 for eSignature
- TrustPro Qualified CA 1 for eSeal
- TrustPro Qualified Root CA 1
- TrustPro Time Stamp Authority service
The fullest Ireland-established provider on the list: qualified certificates for both signatures and seals plus qualified timestamps. The closest thing to a home-grown Irish QTSP covering the signature tier.
Read the cards as coverage, not a ranking. TrustPro and Entaksi are the two Ireland-established providers issuing qualified certificates for both signatures and seals, so they sit closest to the signature tier most operators ask about. Entaksi alone offers qualified preservation, the service that keeps a signed record valid for years. Adobe Systems Software Ireland is listed for timestamps only. Post.Trust (An Post) carries a qualified certificate service under supervision, a different status from the granted entries, so verify the live list before relying on it.

Certificates covers qualified certificates for electronic signatures and, where listed, electronic seals. Parsed from the Ireland eIDAS Trusted List on 2026-07-05T07:00:59.632Z. The live list is authoritative; statuses can change between updates.
An Irish business can use a provider from any EU country
The Irish Trusted List answers "which qualified providers are established here", not "which ones an Irish business may use". Because a qualified electronic signature is recognised across the EU, an Irish company can rely on a qualified certificate from a provider in any member state. The list of where to look is the EU List of Trusted Lists, which links every national register in one place.
The practical takeaway: an Irish operator choosing an e-signature setup is not constrained to the 5 providers above. What matters is that the provider behind a qualified signature appears on some member state's Trusted List with the right qualified service. The Irish list is the natural starting point for an Irish business, and it is the authoritative record of who is supervised here.
Where this sits next to your e-signature software
Trust providers and e-signature software are two different layers. The trust provider issues the qualified certificate and runs the qualified service; the software is the workflow you use to send, sign and store documents. Most e-signature platforms an Irish business uses day to day produce simple or advanced signatures by default and integrate with a qualified provider when a qualified signature is needed.
If you are choosing or comparing that software layer, our e-signature software for Ireland category profiles the tools an Irish business actually uses. For other parts of the stack an Irish operator runs alongside signing, see our invoicing software, accounting software and CRM categories, all built for Ireland.

Frequently asked questions
What is a qualified electronic signature in Ireland?
A qualified electronic signature (QES) is the highest of the three eIDAS levels. It is an advanced signature created with a qualified certificate from a provider on an EU member-state Trusted List, made on a qualified signature creation device. Under Regulation (EU) No 910/2014 (eIDAS) a QES has the equivalent legal effect of a handwritten signature across the EU. Ireland recognises QES through the same regulation that applies in every member state.
How many qualified trust providers are established in Ireland?
5 trust service providers are established in Ireland on the national Trusted List as of 2026-07-05T07:00:59.632Z: Adobe Systems Software Ireland Ltd., Entaksi Solutions SpA Irish Branch, Namirial Limited, Post.Trust Ltd (An Post), TrustPro QTSP Ltd. Of these, 3 carry a granted status across their listed services and one (Post.Trust Ltd) is listed under supervision. 2 offer qualified certificates, 3 offer qualified timestamps, and 1 offers qualified long-term preservation.
Can an Irish business use a qualified provider from another EU country?
Yes. A qualified electronic signature is recognised across the entire EU regardless of which member state the provider is established in. An Irish business is not limited to the providers on the Irish Trusted List; it may use any qualified provider listed on any member-state Trusted List, all of which are indexed through the EU List of Trusted Lists. The Irish list simply shows which providers are established and supervised here.
What is the difference between simple, advanced and qualified signatures?
eIDAS defines three levels. A simple signature is any electronic mark of intent and cannot be denied legal effect just for being electronic. An advanced signature is uniquely linked to the signatory, identifies them, is under their sole control and is tamper-evident. A qualified signature adds a qualified certificate and a qualified device, and is the only level with the equivalent legal effect of a handwritten signature across the EU.
What is the Trusted List and why does it matter?
A Trusted List is the official national register of qualified trust providers and services. Qualified status is not something a provider self-declares; it comes from being on a member-state Trusted List under supervision. Every national list is linked through the EU List of Trusted Lists, so the legal status of a signature can be traced back to an authoritative source rather than a marketing claim.
Does a qualified electronic seal differ from a qualified signature?
Yes. A signature belongs to a person and shows intent to sign. A seal belongs to an organisation (a legal entity) and shows origin and integrity, for example that an invoice or statement genuinely came from a company and has not been altered. Both rely on qualified certificates. On the Irish list, TrustPro and Entaksi are approved for qualified certificates covering both signatures and seals.
