Block AI Attacks. Prevent Data Leaks. Deliver Audit Evidence.

SAGITTERA runs on hardware you control, screens every AI-bound request at the network edge, and produces sealed evidence your DPO decrypts when the auditor asks. Self-hosted. EU-sovereign. Zero-knowledge.

What we screen for

AI attacks

Prompt injection, tool-calling, and agentic attacks are blocked at the boundary before they reach your network.

Sensitive data

Passwords, credentials, GDPR Art. 9 special categories, and personal identifiers are detected and substituted before egress.

Shadow AI

Unapproved AI endpoints your team uses are identified and flagged before they become a breach.

How it works

A transparent gateway at your network edge. No per-app setup. Two deployment models, same protection.

Step 1

Deploy on your hardware

SAGITTERA runs on any machine you own. Install per-machine, or run it as a gateway at your network edge so every device routes through it. WireGuard tunnel forms a secure island.

Step 2

Screen and substitute

A cascade of specialist models screens every AI-bound request locally: prompt injection, agentic attacks, sensitive PII, all PII. When sensitive data is found, it's swapped for a safe stand-in before it leaves your network.

Step 3

Restore and seal

The AI reply returns through the tunnel. Real values are restored inside your network. Every event is sealed to your DPO's public key, tamper-evident, zero-knowledge audit.

📱 Phones covered, on-network and on 5G

When you deploy SAGITTERA as a gateway, phones connect via WireGuard tunnel. This means mobile traffic is captured even when devices are off your local network, because the phone tunnels back to your gateway over 5G. One deployment, full coverage: office WiFi, home networks, and mobile data.

What you get

Runtime evidence for EU AI Act, GDPR, DORA, and Schrems II audits. We provide evidence, not a compliance guarantee. No cloud dependency. No GPU required.

🛡️

Tamper-evident audit

Every event seals to your DPO's public key. Only they can decrypt, zero-knowledge, even SAGITTERA can't read it. Verifiable evidence, not claims.

🔐

Data leak prevention

Passwords, credentials, GDPR Art. 9 special categories, and personal identifiers are detected and swapped before they leave your network. Real values restored on return.

⚠️

Prompt injection defense

Malicious instructions, including covert and agentic tool-call attacks, are screened at the edge. Measured: 93% detection / 0% FP on prompt injection, 98.9% / 1.1% FP on agentic attacks.

👀

Shadow AI detection

Identify AI endpoints your team uses but you didn't approve (chatgpt.com, claude.ai, deepseek.com). Flag unsanctioned use before it becomes a breach.

🔑 You Hold the Keys

Your DPO controls the decryption keys, not us, not anyone else. Audit logs seal to their public key and only they can open them. We built it so we cannot see your data, even if we wanted to. You control the evidence. We provide the mechanism.

For Datacentre Operators

Your clients need to prove model authenticity and EU data residency. SAGITTERA gives you both, as a value-add you can offer.

How you run it as a service

SAGITTERA is a fleet of gateway instances you run inside your network, offered to clients as a managed service.

⚙️

Fleet behind a load balancer

Run one or more stateless gateway instances behind a load balancer. Client AI traffic routes through them; capacity scales by adding nodes horizontally, no per-client setup.

📊

Central logging

Every gateway pushes sealed, tamper-evident events to one central audit service. One unified compliance trail across your whole fleet and all your clients.

🔐

Tenant-isolated evidence

Each client's sealed logs are encrypted to their own key. Only their DPO can open them. You, and other tenants, cannot read them. This is what makes multi-tenant safe.

📈

Simple, scalable installation

Each gateway deploys the same way. Add nodes as demand grows; remove them as it falls. Stateless screening means scaling is trivial and predictable.

✓

Model authenticity proof

Show AI-hosting clients that the models running on your infrastructure are verified and untampered. The sealed audit log is evidence clients can open themselves.

🇪🇺

EU data residency

SAGITTERA runs on your hardware, self-hosted, EU-sovereign. Data never leaves EU jurisdiction, verifiable by your clients.

🔒

Multi-tenant isolation

Each client gets their own secure island. WireGuard tunnels isolate traffic, screening per-tenant, audit logs segregated by public key.

💰

A billable value-add

Turn sovereignty into revenue. Offer "EU AI-sovereign hosting" as a premium tier, SAGITTERA is the infrastructure that makes the claim verifiable.

Compliance alignment

SAGITTERA provides the evidence layer your DPO needs. We do not make you compliant, compliance is your responsibility. We provide evidence, not a compliance guarantee.

EU AI Act

Tamper-evident logs support Article 15 transparency and record-keeping obligations.

GDPR

Cross-border transfer logs support Schrems II documentation requirements.

DORA

Tamper-evident seals support third-party risk documentation.

Your DPO holds the keys

Only your Data Protection Officer can decrypt the audit trail, zero-knowledge by design.

When a Breach Is Attempted: The 5-Step Response

What happens the moment sensitive data tries to leave your network.

Step 1

Detect

The client screens every AI-bound request at the network interface. Specialist models identify sensitive data, prompt injection attempts, and unapproved AI endpoints.

Step 2

Substitute or filter

When sensitive data is found, it's swapped for a safe stand-in before it leaves your network. Malicious payloads are blocked. The AI still receives a valid request, just not your real data.

Step 3

Seal the log

The event is recorded and cryptographically sealed to your DPO's public key. Tamper-evident. Zero-knowledge. Not even SAGITTERA can read it.

Step 4

DPO decrypts

Only your DPO holds the private key. When they need to review an incident or prepare for an audit, they decrypt the log. No waiting on us. No access requests.

Step 5

Evidence delivered

The decrypted log shows exactly what happened: what data was at risk, how it was handled, and that it never left in plaintext. Verifiable evidence for your auditor.

Why SAGITTERA

●

Network-level, not per-app. No SDKs, no integrations. SAGITTERA sits at your network edge and screens all AI traffic automatically, regardless of which app or browser sends it.

●

EU-sovereign, self-hosted. Runs on hardware you already own. No cloud dependency. No data leaves your control. Models run locally, no GPU required.

●

Zero-knowledge audit. Every event seals to your DPO's public key. Only they can decrypt. Even SAGITTERA cannot read the audit trail, tamper-evident by design.

●

Compliance-ready evidence. Tamper-evident logs your DPO decrypts, not a vendor claim. Aligned with EU AI Act, GDPR, DORA, and Schrems II.
