We secure and monitor your AI traffic while ensuring compliance
The all-in-one gateway for AI observability, prompt injection defense, PII masking, compliance and cost savings. All from a single endpoint your app already speaks.
Trusted by teams shipping AI in production
Integrates with your stack. Works with the models you already use.
Secure every AI provider
One gateway for all the models you use — current and future.
Security that works at machine speed
Your AI processes thousands of requests per minute. Your security should too.
Real-time detection in milliseconds
Not hours waiting for human review. Not another ticket in the queue. Threats are stopped before they reach your model.
AI security can’t be run by AI
You need deterministic security, not another LLM guessing whether a prompt is safe. Pattern matching and rule engines beat probabilistic models every time.
Built for enterprise. Hosted in Germany.
Dedicated hardware on Hetzner. No shared infrastructure, no multi-tenant surprises. Your data stays where your compliance team says it should.
Protect before it happens, not after
Most platforms notify you after a breach. Bastio blocks the threat in-flight — your users, employees, and business stays safe
99% of AI deployments are not secure
And 99% are not compliant. If your AI security strategy is “we trust the model,” you don’t have a security strategy.
Choosing a copilot is not a security solution
Vendor lock-in disguised as security. Bastio works with every provider — OpenAI, Anthropic, Gemini, Mistral — so your security doesn’t depend on your model choice.
Live in under 30 minutes
No complex integration. No infrastructure changes. Just point, configure, and go.
Step 01
Connect
Point your API traffic to Bastio. Keep your existing providers, keys, and prompts. One line of code.
Step 02
Configure
Pick from preset security policies or build custom rules for threats, data handling, and spend limits.
Step 03
Protected
Watch threats get blocked, costs drop, and compliance evidence stack up — all from one dashboard.

LLM Firewall that
The Cloudflare for LLMs
Production-grade infrastructure controls that protect your AI stack from abuse, reduce API costs, and give you full visibility into every request.
Bot Detection
Fingerprint-based detection blocks scrapers, credential stuffers, and automated abuse before they reach your model.
Per-user, per-key, per-endpoint limits with adaptive throttling.
Semantic caching cuts redundant LLM calls and costs.
Infrastructure Controls
Geo rules, allow/block lists, and full traffic analytics across every proxy.
Threat Detection
Your AI app is one injection away from disaster
Attackers don't need to hack your servers. One crafted prompt can bypass guardrails, leak instructions, or trigger unintended actions.
- Catch prompt injections, jailbreaks, and indirect web attacks
- Block, sanitize, or warn — per policy
- Every decision logged with a clean audit trail

Observability
You can't secure what you can't see
Most teams can't answer basic questions: what users asked, what the model returned, and why a request was blocked or allowed.
- Trace prompts, responses, tokens, cost, and latency
- Session grouping for real user journeys
- Security context attached to every trace
Full tracing
Every request traced end-to-end with session context

Cost Control
You're paying for prompts that shouldn't reach your model
Bot traffic, repeats, and unoptimized routing silently inflate your LLM bill. Bastio cuts waste before the invoice arrives.
- Cache safe responses and filter automated abuse
- Route requests by cost, latency, or reliability
- Set spend limits and get alerted early
