Cohere caught Alibaba Group's Qwen attempting to send data to a server in Beijing, right after the model said it wouldn't use external tools.
The security sandbox blocked the attempt, with no confirmed evidence of malicious intent.
But imagine this happening when an AI agent has access to your company's private repositories, credentials, and internal systems.
A clear reminder that AI agents cannot be expected to enforce their own security boundaries.
How are you enforcing company-wide security policies across your AI coding agents before they execute actions?
If you're not doing this yet, reach out to us at @hardenrun . We'd love to show you how to enforce custom policies across your organization and deploy them across your developers' machines.

Harden after outranking frontier companies 💀
🚨META JUST LOST TO 3 STARTUPS ON PRODUCT HUNT.
Muse by Meta launched yesterday and finished #5.
Mastra Factory: #1 → @mastra
Harden: #2 → @hardenrun
ChatGPT Images 2.5: #3
Noodle Seed: #4 → @Noodle_Seed
Muse by Meta: #5 → @muse
Meta has billions of users and basically unlimited distribution.
and somehow Muse finished one rank above “Ass Auction” 😭

You know who just got featured in the Product Hunt newsletter? 👀
They picked up “babysitting” for the subject line and made us a major headline today.
Great work lets keep pushing! 🚀

Coding agents can now work for hours on their own.
You shouldn’t have to babysit every action they take.
Harden watches what your agents do and catches risky actions before they happen.

Security should not make you switch coding agents.
That is why Harden AIF works with the agents you already use: Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, and OpenClaw.
You can try it free at: harden.run/
Using a different AI coding agent or workflow? Tell us what you use. We’re expanding compatibility and would love to build for it next.

Protection is foundational in financial services.
Harden is proud to join the Financial Institution Insurance Council, FIIC.
As AI changes how financial institutions build and operate software, security and control need to be built in from the start.

When Harden says “block,” it means that tool call will not run, but it does not mean the task is over.
AIF looks at what the agent is trying to do, the developer’s intent, and the context of the session. If the task is legitimate but the proposed call contains something unsafe, such as a secret pasted into a patch, AIF can rewrite the call safely by redacting the secret and preserving the intended work.
The creative below shows exactly that: the original call is stopped before execution, protected input replaces the exposed secret, and the agent can safely retry.
If an action goes beyond the developer’s approval, breaks an organization’s policy, or cannot be made safe, AIF blocks it. That is by design.
The goal is not to create more interruptions. It is to keep legitimate work moving while preventing unsafe actions from reaching your code, data, or environment.
AIF can allow a call, rewrite it safely, or block it when there is no safe path forward.
Harden AIF is free for individual developers. Try it at harden.run/
“Trust me bro, the agent knows what it’s doing” is not a security strategy.
One rogue tool call, a hallucinated instruction, or a small context mistake can become a real action in your codebase, credentials, or environment.
That is why Harden AIF sits between coding agents and the tools they use.
Before Harden AIF, tool calls can run unchecked. With Harden AIF, every supported call is checked before it runs. Safe actions continue, sensitive data can be redacted, and actions that go beyond the developer’s intent or a team’s policy are blocked.
Give your coding agents autonomy, not unchecked access.
Harden AIF runs locally and is free for individual developers: harden.run/

Your coding agent can run commands, use tools, and touch your entire codebase
And most of you have ZERO controls on it
Harden AIF fixes that
Local security model reviews every tool call in context and stops the unnecessary or risky ones before they execute
Runs fully local
Repo context stays private
Dashboard + activity logs + searchable sessions so you can see exactly what your agent did
Free forever for individual devs
curl -fsSL aif.harden.run/install.sh | sh
This is the way

Introducing Harden Agentic Integrity Foundation (AIF), the unified security layer for AI coding agents
We believe the future of software engineering is long running agents taking on complex work while keeping your data, credentials, and critical secrets safe.
So we built AIF
→ Evaluates every action before execution
→ Uses developer intent and session context
→ Blocks unsafe actions or makes them safe
→ Runs locally and records every decision for audit
Whether you use Claude Code, Codex, Cursor, Antigravity, Kiro, OpenClaw, or Hermes, AIF works with the agents you already use.
AIF is not another dashboard or copilot. It is the security layer between your coding agent and the systems it can affect
Our post-trained model outperforms frontier models across critical agent-security benchmarks
AIF is free for individual developers: harden.run/?utm_source=twitt…
Need help getting started? Book a call, and our team would be more than happy to help you get set up: calendar.app.google/GdL3BvBu…
