AI security
Which AI is at work in your company, what it can access and how you secure it.
What's happening now
AI is already in your business. The question is what it can access.
Shadow AI
Customer data in outside AI services
One short prompt in a chat assistant, and quotes, contracts or customer data end up with an outside service.
AI attacks
The email sounds just like your boss
Attackers use AI to write emails, voices and messages that feel genuine. Faster and more convincing than ever.
Excessive permissions
An AI agent with a master key
If an AI assistant has more permissions than its task needs, whoever takes it over can reach everything it is allowed to see.

Quantum-safe encryption
How to encrypt your data today against the computers of tomorrow.
Quantum computers change the rules.
And the clock is ticking: the BSI recommends an end date for relying on classical encryption alone.
BSI guidance: 2030/2031 cut-off
On 11 February 2026 the BSI recommended end dates for classical asymmetric encryption: RSA and ECC should be used on their own only until the end of 2030 for highly sensitive data, and until the end of 2031 in general. After that, only in combination with quantum-safe schemes. Public authorities and critical infrastructure are urged to migrate now.
Source: BSI TR-02102-1 (2026 edition) · BSI press release of 11 Feb 2026
For decision-makers
- Sensitive data (case files, citizen records, communications) must stay protected today and in ten years.
- “Capture now, decrypt later”: attackers collect data today in order to decrypt it with future computers.
- Under NIS2 and GDPR, what counts is that your cryptography reflects the state of the art and is documented.
For developers
- Finding and evaluating the right encryption library takes time.
- Is my existing code even quantum-safe?
- Add quantum-safety without putting your running project at risk.
Captured today, decrypted tomorrow. Stop it now
Encryption that stands up to quantum computers.
SaQura brings post-quantum cryptography to .NET, Android, iOS, Web, Python and C/C++: via a package, without rebuilding your existing project. The same encryption on every platform.
FIPS 203 / 204 / 205 algorithmsMethods recommended in BSI TR-02102-1 availableDocumentation for NIS2 & GDPRIdentical on every platform
Your path
Three ways to quantum-safe encryption.
You decide how much you do yourself. We take care of the rest.
SaQura Library
As a package in your app
Your developers add SaQura via their package manager. Encryption runs on your infrastructure; your data and keys stay with you. For .NET, Android, iOS, Web, Python and C/C++.
Learn moreSaQura Crypto API
As a ready-made service
You call a secured REST API. No cryptography of your own to write, no servers of your own to run.
Learn moreConsulting and implementation
We implement it for you
We work with you to move your systems to quantum-safe encryption. And if the right tool doesn't exist yet, we build it.
Learn moreStandards
Two profiles: the NIST standard or methods recommended by the BSI. One library. You choose.
The NIST standard, or a conservative profile with methods the BSI recommends in its Technical Guideline TR-02102-1: both are built in. One setting decides.
NIST standard · FIPS 203
ML-KEM for key exchange, NIST's post-quantum standard FIPS 203.
For: teams following the international standard.
Conservative profile · BSI TR-02102-1
FrodoKEM-976 and FrodoKEM-1344, as recommended in BSI TR-02102-1: conservative by design and thoroughly studied for years.
For: government, critical infrastructure, anything that must stay secret for decades.
In the NIST profile we combine ML-KEM with proven classical encryption (X25519, hybrid), as the BSI recommends for the transition. If one breaks, the other holds.
In plain terms
You get the NIST standard right away. Want especially conservative methods, say for government files? Switch to the BSI profile. One setting, no rebuild.
// NIST standard: FIPS 203 var gen8 = await Quantum.GenerateKeyPairAsync(QuantumStrength.Standard, QuantumGeneration.Gen8); // X25519 + ML-KEM // BSI TR-02102-1, conservative var gen6 = await Quantum.GenerateKeyPairAsync(QuantumStrength.Medium, QuantumGeneration.Gen6); // FrodoKEM-976
Simplified example. See the docs for exact syntax.
One solution, both worries handled.
Quantum-safe protection for those responsible, lean integration for developers, on your own infrastructure.
Quantum-safe, today
Proven and quantum-safe methods combined, protecting against tomorrow's computers too. For developers: implements FIPS 203, 204 and 205.
Sovereign, on your infrastructure
Encryption runs entirely on your side: no cloud, your data and your keys stay yours. For developers: built right into your application; only the license check may go online, and with a license file there is no outside connection at all.
Audit documentation included
Brings the cryptographic building blocks and their documentation for BSI · NIS2 · GDPR, covering the encryption part of your audit. In the Enterprise package, we build further compliance components for you on request. For developers: integrated as a package, no rewrite, identical on every platform.
Healthcare
Patient data, encrypted quantum-safe.
Health data is especially sensitive and long-lived: attackers store encrypted data today in order to decrypt it later with quantum computers (“harvest now, decrypt later”). Classic encryption like RSA or ECC offers no lasting protection against that.
In healthcare this is decisive: a patient record, once leaked, cannot be taken back. The protection has to hold from the very start.
The dental clinic Hälsa Dental got ahead of it, and already encrypts patient data quantum-safe with SaQura: proven and post-quantum methods in one.
Confidentiality that lasts.
Hälsa Dental websiteHow it works
Quantum-safe in three steps.
Installed as a package, integrated right into your project: your developers do it themselves.
1
Add it
Add SaQura to your project via the package manager, with no setup or servers of your own.
2
Choose protection
Proven or quantum-safe encryption: one setting, you decide per application.
3
Encrypt
Encrypt and decrypt your data the same way everywhere, entirely on your own infrastructure.
Available for .NET, Android, iOS, Web, Python and C/C++.
Compliance
BSI, NIS2, GDPR: SaQura delivers the encryption and its documentation for your audit.
NIS2 requires the organisations it covers to have policies for the use of cryptography, the GDPR names encryption as a safeguard in line with the state of the art, and in an audit what counts is what you can prove. SaQura supports exactly that part: built to recognised standards, with evidence for procurement and review. So you can back up the encryption part of your audit with your own team. In the Enterprise package, we build further compliance components for you on request.
