Quanterios is the cryptographic and AI security and governance platform for European regulated industries. Two products on one architecture, Quanterios Crypto for the cryptographic estate, Quanterios AI for the AI estate, designed from day one against DORA, NIS2, eIDAS 2.0, the EU AI Act, BSI TR-02102, and CNSA 2.0.
NIST finalised FIPS 203, 204, and 205 in 2024. NSA's CNSA 2.0 is publishing hard deadlines through 2033. The EU AI Act started phasing in obligations in 2025. DORA went live the same year. BSI is publishing post-quantum guidance for German regulated industries.
Adversaries are capturing encrypted traffic today. Data with ten-year sensitivity windows is already at risk. AI agents with MCP-server scope are running in customer-facing production with no policy gate at runtime.
Most cryptographic-governance products were built for a world where algorithms were static, they catalogue what is broken and hand the customer a PDF. Most AI-governance products are AIBOM-only inventories with a chat widget bolted on. Quanterios is built for the world that's actually here: continuous algorithmic evolution and adversarial AI.
Every output the platform produces, every risk score, every migration playbook, every runtime block on an AI agent, flows through a reasoning layer grounded in a proprietary migration-outcomes corpus. This is the architecture, not a feature.
Discovery has zero production footprint. Nothing to install on hosts, no agent process to maintain, no performance risk. Cryptographic and AI inventories are produced by reading the existing infrastructure surface, not by instrumenting it.
Region-pinned data planes. EU-based engineering. Written for DORA, NIS2, eIDAS 2.0, the EU AI Act, and BSI guidance on day one, not retrofitted. €-based contracts, CET / GMT support hours, German DPO.
Cryptographic security and governance, and AI security and governance, share the same five-step lifecycle and the same Decision Engine. Customers buy either standalone or together. No forced bundling, no separate dashboards.
Every finding maps to specific regulator articles. Evidence packets are built from live data and refreshed weekly. Audit teams work with the same artefacts the platform produces, on the same day.
Cryptographic risk doesn't end with the post-quantum migration. AI risk doesn't end at the EU AI Act deadline. Quanterios is the security and governance layer customers rely on permanently, we don't ship audit projects, we ship operational control.
Quanterios is one of the operating brands of the Plothner Group , a European holding focused on infrastructure-grade security and governance software. Plothner Group also operates Tessera (cryptographic attestation infrastructure, currently paused) and other specialist brands.
The shared infrastructure model means Quanterios benefits from the group's region-pinned data planes, signed CSP support contracts, and operational maturity from day one, without having to rebuild the basics.
Plothner Group overviewWe never write 'AI-powered' as an empty claim. Every reasoning output is cited. Every breakage prediction is grounded in evidence the customer can verify.
We say 'NIST finalised FIPS 203 / 204 / 205 in August 2024', not 'quantum computers will break your encryption tomorrow.' Adversaries are real. False certainty is not how we sell.
Buyers see plain language at first impression, 'cryptographic inventory,' 'AI security,' 'compliance evidence.' Evaluators get the technical depth, CBOM, AIBOM, ML-KEM-768 hybrid, MCP scope policy. Same product, different surface.
We don't ship one-time audit projects. We ship the platform of record customers rely on permanently. Pricing reflects that, recurring subscription, API metering, certificate-renewal revenue. No retainer-plus-project.
Quanterios runs on region-pinned data planes in Frankfurt (primary), Dublin (failover), and Zurich (sovereign). EU-based engineering, German DPO, signed CSP support contracts with named delivery teams.
DACH-based, EU-pinned, building the cryptographic and AI governance platform Europe actually needs.
