Your agents read tool output, retrieved documents, web pages and email you do not control. A prompt hidden in any of them is an instruction your model will follow. Tawa Guard scans that content first and returns a decision your code acts on: allow, review or block.
5 million Tawa Units free every month. No card, no trial period, no detection held back. 1 Tawa Unit = 1 character scanned on the default engine, minimum 100 per scan.
Tawa Guard benchmark v13, 17 September 2026. Engine tawa-hybrid-1, every detector under the same thread budget. Benchmark figures, not production figures.
An agent that reads a web page, opens a ticket or calls a tool takes in text written by someone else. The model cannot tell your instructions from theirs. Telling it to ignore injected instructions is a request, and a request is not a control.
Tawa Guard treats every one of those inputs as untrusted, scores it, and hands your code a decision before the agent takes its next step.
Search results, CRM records, ticket bodies and API responses. The agent reads them as fact and follows anything shaped like an order.
/v1/agent/tool-outputEvery chunk your RAG pipeline pulls in is a chance to plant an instruction. One poisoned PDF in a knowledge base reaches every conversation that cites it.
/v1/rag/chunkBrowsing agents and inbox assistants read content written by strangers. Text a person would never notice on the page still counts as an instruction to a model.
/v1/scanOne API call returns the decision. The platform around it gives your security team the policy controls, the evidence and the operational hooks they already expect from a gateway.
A multi-layered detection cascade: fast heuristics score every input, deeper analysis runs on anything ambiguous, and a calibrated decision comes out the end. All of it fast enough for the request path.
Allow, review or block, with thresholds you set per surface. Policy Studio turns your rules into versioned policy, with validation and history.
Every scan keeps its evidence: the detector signals, the rule that acted, the spans it matched in your own input and the raw engine result.
A dashboard for live activity and trends, with the exports and controls a security operations team runs on.
You send each untrusted input to Tawa Guard before the agent uses it. We return a decision and the evidence behind it. With the SDKs, your code decides how to handle it, so there is no proxy to route through. With the proxy, Tawa Guard blocks directly.
tawa-hybrid-1Your policy: score < 0.30 pass · 0.30 to 0.80 review · > 0.80 drop
One call per input, from the HTTP API or one line of the Python or TypeScript SDK. Nothing to host and no model to run.
The default engine's median is 23 ms in-process on our benchmark. Ambiguous inputs cascade to deeper analysis without you asking.
Allow, review or block, with per-category scores, a rationale and a request id you can replay later. With the SDKs, your code decides what happens next.
We test on held-out attacks, each rewritten through the evasions we see in the wild, and on public datasets with any row that appears in our training data removed. Every figure carries a Wilson 95% confidence interval.
We run every open detector we compare against on the same machine, the same rows and the same 1% false-positive budget, because a fixed score cut flatters whichever calibration it suits.
Read the method and the full tablesOne endpoint, typed SDKs and a free tier large enough to run a real workload. Thresholds per surface, so a browsing agent and a support bot get different review floors.
Author rules in Policy Studio, simulate them against recorded traffic, and promote a version when you are satisfied. Every decision keeps the signals and spans behind it.
Point a knowledge bucket at your documents and we scan each chunk as it is ingested, with PII handled the way your policy says. Poisoned documents surface before a user ever cites them.
Tawa Guard scores text. It does not care which model reads it afterwards, which cloud you run on or which agent framework you chose.
Detection is the same on every plan: the same input gets the same verdict whether you pay nothing or run an enterprise contract. Paying buys more protected apps, more volume, policy controls and a fuller view of the analysis behind each decision.
5 million Tawa Units a month, one protected app, every available engine and the full decision on every scan. It is a hard cap, not a trial, so a free workspace can never run up a bill.
1 Tawa Unit = 1 character scanned on the default engine, minimum 100 per scan.
Tell us how many apps you protect and how much you scan, and we will quote a plan sized to it. Usage beyond what is included draws on a budget you set, never a charge you did not choose.
Your scans contain your customers' data. We process them in the UK, keep them only as long as you tell us to, and give you the controls to prove it.
Benchmark reports, how we measure, and what changed between releases. Conditions stated on every number.
Nine datasets, 14,865 rows per engine, four open detectors and two rules. Every detector gets the same thread budget and the same false-positive budget. Here is what the numbers look like when nothing is tuned in our favour.
Read the reportEvery plan gets the same engines and the same verdicts. What changes between plans is reach, volume and how much of the analysis you can read afterwards.
Read the postWhy we pin every model to the same thread budget before quoting a latency, and what that does to the numbers vendors usually publish.
Read the noteWhat to decide around the scan call: what each error costs on each surface, how a flag should change what the agent can do, and how to check the numbers on your own traffic.
