The short version

  • Docker starts at $11/mo; Signicat prices on request.
  • Only Docker lists container runtime; only Signicat lists eID scheme brokering.
  • Where Docker falls short: shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Signicat

  • National eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly
  • Value is concentrated in Northern and Western Europe, and coverage in Southern and Eastern Europe is thinner, so a pan-European rollout still hits gaps requiring document fallback
  • Pricing is per transaction and quoted, and because scheme rates vary by country the cost per onboarded customer differs materially between markets in ways that complicate unit economics
  • Each eID scheme connection typically carries its own setup fee and approval process, so adding a country is a project with a lead time rather than a configuration change
  • Availability is tied to the national schemes, meaning an outage at BankID or MitID stops your onboarding entirely and there is no vendor-side mitigation for it

Questions people ask

Is Docker or Signicat better?
Neither clearly leads. Docker starts at Free and Signicat at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Docker or Signicat?
Docker has a free tier; the other does not. Paid plans start at Free for Docker and On request for Signicat.
Does Docker or Signicat run on more platforms?
Docker runs on Linux, macOS, Windows. Signicat runs on Web, iOS, Android.
Can I use Docker for free?
Yes. Docker has a free tier, so you can try it without paying. Signicat starts at On request.
What is Docker best used for?
Docker is most often used for application containerization, microservices, ci/cd pipelines, development environments. Of those, application containerization and microservices are not what Signicat is typically brought in for.
What can Docker do that Signicat cannot?
Docker covers Container runtime, Docker Desktop, Docker Hub, Docker Compose. Signicat covers eID scheme brokering, Qualified electronic signatures, Document verification, AML screening.

Answered from the vendors’ own pages

Docker: What is Docker pricing?

Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.

Source
Signicat: Is this an alternative to a document verification vendor?

Only where national eID exists. In markets with a mature bank ID scheme it is better; elsewhere you fall back to document checks, which Signicat also provides.

Docker: Can I use Docker in production?

Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.

Source
Signicat: Do we still pay the eID schemes?

Yes. Scheme fees are passed through in addition to Signicat charges. Ask for the split when comparing to a direct integration.

Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
Signicat: Are signatures legally qualified?

Signicat supports eIDAS qualified electronic signatures, which carry the highest legal standing in the EU, as well as advanced signatures.

Docker: Does Docker integrate with CI/CD systems?

Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.
