Your developers put
your data into AI tools
every day.
You can't see what leaves.
Tether shows you what your team sends to AI tools, blocks what's dangerous, and keeps proof you can hand to an auditor — all inside your own cloud.
Code, secrets, and customer data go into Claude Code, Cursor, Copilot, and the rest all day long. The security tools you already own can't read any of it. Tether runs on the developer's machine, shows you that traffic, stops the risky moments, and keeps a signed record — without getting in your developers' way.
How much you see depends on the tool. For the ones that connect through Tether — Claude Code, Codex CLI, Aider, Zed, Continue — you see the full prompt. For the ones that don't, like Copilot chat or Cursor's default mode, you still see who used them and which AI vendor they hit.
Free for up to 25 developers, two weeks, in your own cloud. If it's not for you, delete it — there's nothing on our side to clean up.
One hop — and it never
leaves your cloud.
Your developer's AI tool reaches the model through Tether, running in your own cloud account. Tether sees the request, applies your policy, and records it. Nothing routes through us.
No Tether-hosted transit. Policy verified offline. No root certificate on the laptop.
You are paying for security tools
that cannot see AI traffic.
Data loss prevention is blind to developer AI tools. Here is why your current stack misses the prompt.
EDR does not see prompts.
Your EDR sees the process, the network connection, the binary. It does not read the JSON body inside the TLS tunnel a coding agent opens to its vendor.
CASB does not classify them.
CASBs are tuned for SaaS-app posture and shadow-IT discovery. A Claude Code or Cursor call to api.anthropic.com is just another approved SaaS host.
DLP does not catch them in flight.
Network DLP runs on egress patterns at the perimeter or on file content. A developer paraphrases a customer record into a prompt and the patterns never fire.
Vendor logs are not discoverable.
The only record of what your developers prompted is at the AI vendor. It is not in your SIEM, not on your audit timeline, and not available during incident response.
You do not need to replace your stack. Tether covers the exact blindspot your other tools can't reach, and feeds the evidence directly into the SIEM you already operate.
- Sees prompts and completions before they leave, on the tools that route through the proxy
- Attributes activity to a person, an agent, and a host
- Blocks the patterns you name; pauses the ambiguous moment for an operator
- Leaves signed evidence your auditor re-verifies offline
- EDR still does endpoint malware and behavioral threat detection
- CASB still does SaaS shadow-IT discovery and posture
- IdP/SSO still owns identity; Tether reads from it, doesn't replace it
- DLP still does org-wide file-level content classification
That's the short version. The full 13-row map — including the rows where Tether is only partial — is on the Pilot page, and the category-by-category fit — network/SASE, supply-chain gateways, EDR, CASB, DLP, IdP — is on How it works.
The day this matters is the day
you can't answer the question.
Three moments when "we don't have a record" becomes an immediate crisis.
The auditor asks what left.
SOC 2, FedRAMP, an AI-governance review — the control owner asks for evidence of what your developers sent to AI tools, and which policy decided it. Today the only record is at the vendor, and it isn't on your timeline.
Incident response has no trail.
2 a.m., a credential is being used from an IP you don't recognize. Your IR lead asks the one question that scopes the blast radius: did it go out through an AI tool, and what else went with it? The only record that could answer is at the AI vendor — off your timeline, behind a support ticket, useless to the people on the bridge right now.
The mandate lands with a date on it.
A customer contract, a regulator, or your own board sets a date to govern AI usage. A control you can stand up, prove, and tear down in two weeks beats a year-long platform program — and the AI tools are already in production.
Close the gap before you're asked.
Tether turns this blind spot into a verifiable, tamper-evident audit trail running entirely in your environment. You hold the keys, and your auditor checks the math. Try it on your own data in two weeks →
Three things your board
is about to ask about.
You don't need a statistic to feel this one. It's already true in your own org.
Your developers already use AI tools every day.
Claude Code, Cursor, and Copilot got into your engineering org faster than security got any view of what leaves with them. That gap is widening, not closing.
The prompt body isn't in your SIEM.
Today the only record of what a developer sent to an AI tool sits with the AI vendor — not on your timeline, not in the tools your SOC actually watches.
Auditors have started asking.
SOC 2, HIPAA, and AI-governance reviews increasingly ask what controls AI-tool egress. "We have no record" is a hard answer to give with a straight face.

Proof your auditor can check
without taking our word for it.
Most security tools ask your auditor to trust a vendor dashboard. Tether does the opposite: every decision it makes is saved as a signed record your auditor can verify on their own laptop — no access to us, no reason to trust us. That's the answer to "will this hold up in an audit?" — and it's the same answer whether it's a customer, a regulator, or your own incident team asking.
The controls you need, built to be proven.
We don't sell black-box AI. We sell deterministic security controls that you can verify in your own environment on day one.
Read the prompt before it leaves
The developer's prompt, the AI's response, and the exact identity of the sender are captured at the endpoint and shipped directly to your SIEM. You see what the TLS tunnel hides from the network.
Proof: Watch the exact prompt land in your SIEM in real-time.
Block the dangerous payloads
Normal traffic flows uninterrupted. When a policy triggers, the request is held at the endpoint. The developer gets immediate feedback, or an operator clears it in seconds.
Proof: Change a policy and see it enforced on a machine in seconds.
Cryptographic evidence for auditors
Every enforcement decision is tied to the exact policy version active at that millisecond, signed with an Ed25519 key. You don't ask us for a report—you hand the auditor the signed bundle.
Proof: Your auditor verifies the cryptographic signature offline.
No TLS interception required
We do not install a MITM root certificate on the developer's laptop. Tether binds to the local loopback and only proxies the AI developer tools you choose. The rest of their traffic is untouched.
Proof: Inspect the developer machine. There is no Tether CA installed.
Built for the stack you own
Tether pulls identity from your IdP, reads device posture from your MDM, and pushes events to your SIEM. It is a targeted, surgical addition to your existing security architecture.
Proof: Connect Tether to SSO and SIEM during the first hour of a pilot.
