buyer's guide

Assessing suppliers under NIS2: the tools and what separates them.

NIS2 requires in-scope entities to manage the risk in their supply chain, and each member state transposes that obligation into national law. In practice it means getting a reliable answer out of dozens or hundreds of suppliers, many of them small, with no security team and no incentive to reply quickly. The tools on the market divide by how they attack that problem: by questionnaire, by external observation of the supplier, or by managing the compliance of the organisation doing the asking.

Listed alphabetically, not by preference. Each product is described by its category and the audience it serves, from its own public documentation. Third-party pricing is omitted because most of it is quote-based.

The criteria that decide, in order.

Supplier response rate is the number that determines whether the programme finishes. Almost everything else is secondary.

  1. How easy it is for the supplier to reply. If it requires creating an account, installing something or learning a tool, a significant share will not answer, and the problem becomes chasing rather than security.
  2. Questionnaire, external observation, or both. External observation gives signal without asking the supplier for anything but does not cover process; a questionnaire covers process but depends on someone answering.
  3. Whether the right framework is covered. For NIS2 that means the national transposition and, in Portugal, the QNRCS; ISO 27001 and ISO 27036 show up in the same programmes.
  4. Whether it serves the obligated entity or a service provider. A consultant or auditor running this for several clients needs them kept apart, and most platforms assume a single tenant.
  5. Where the answers sit. This is third-party security data, and the supplier is entitled to ask where it is stored.

Optro

A compliance automation platform oriented to the European market, with dedicated material on NIS2 and ISO 27001.

Not for: Anyone who mainly needs external observation of a supplier's exposed surface.

Orbiq

Best for: NIS2 compliance with an EU market focus

Specialised in third-party risk: pairs supplier questionnaires with external assessment of their exposed surface.

Not for: Preparing the internal compliance of the organisation asking.

UpGuard

Best for: Continuous external attack-surface observation

Continuously assesses the external exposure of an organisation and its suppliers, without depending on the supplier replying.

Not for: Collecting documentary evidence of process, which only the supplier can provide.

Vanta

Best for: Automating your own organisation's compliance

Not for: Running a supplier assessment programme on behalf of several clients.

foraudits

Best for: Consultants and auditors running supplier assessments for clients

Questionnaires sent to the supplier without requiring an account, with response chasing, evidence collection and analysis. Several clients in parallel, kept apart, under the service provider's brand.

Not for: Continuous external attack-surface observation, and automating your own ISO 27001 certification. We do neither; the platforms above are the right choice for both.

What people ask.

What are the best NIS2 supplier assessment tools in Europe?
There are three families rather than one ranking. Third-party risk platforms, which combine questionnaire and external observation; external observation platforms, which assess a supplier's exposure without asking them anything; and compliance automation platforms, aimed at preparing the certification of the organisation doing the asking. The right one depends on whether you need fast signal, evidence of process, or both.
Is a security questionnaire enough for NIS2?
A questionnaire documents the process the supplier declares, which is necessary but rests on their answer. External observation adds independent signal but cannot see internal process. Serious programmes use both and assume neither is sufficient proof on its own.
How do you get small suppliers to actually respond?
Lower the cost of replying. Every extra step — an account, a portal login, a tool to learn — loses a share of respondents, and the ones lost are disproportionately the small suppliers that carry the least security maturity and therefore the most risk. This is the practical constraint the whole programme turns on.
Does foraudits certify NIS2 compliance?
No. foraudits is not a certification body and is not accredited to certify. It collects and organises the assessment and returns the analysis; the decision and the responsibility stay with the obligated entity and its advisers.

Running supplier assessments for clients?

If the problem is the response rate from smaller suppliers, that is the point foraudits was built to help with.
