A Coding Agent
Firewall.
(Yes, that's a thing now.)
A Coding Agent Firewall sits between an AI coding agent (Claude Code, Cursor, Kiro, Copilot) and the cloud APIs it can call. It blocks the actions you never want an agent to take, gates risky writes on human approval, and turns every agent action into an identity-stamped audit log. Cloudanix builds one.
What is a Coding Agent Firewall?
A Coding Agent Firewall is a security control plane that sits between an AI coding agent (Claude Code, Cursor, Kiro, Copilot, Aider) and the production resources the agent can act on — cloud APIs, databases, SaaS endpoints. It evaluates each agent-initiated action against policy, blocks destructive or out-of-scope actions, gates risky writes on human approval, and produces an identity-stamped audit log tying every action back to the human operator behind the agent.
Every Coding Agent Firewall does four things.
Block
Actions that should never happen — DropTable, DeleteDBInstance, prod-cluster terminations, secret retrieval from sensitive vaults — fail closed at the firewall, before they reach the cloud API.
Gate
Actions that might be OK — risky writes, large reads, schema migrations — pause for human-in-the-loop approval. Slack DM, Teams ping, web modal — whatever fits the team.
Scope
Allowed actions get short-lived, intent-scoped credentials brokered to the agent. The agent never holds long-lived keys; the session dies when the work is done.
Audit
Every action — passed, blocked, gated — produces an identity-stamped log line: which agent, which human operator behind it, which policy fired, which resource was touched.
"I asked Claude to clean up the test database
and it cleaned up the wrong one."
Three things changed in the last 18 months. Each one made the prior generation of security tools insufficient.
Agents started calling cloud APIs directly
Before MCP, coding agents wrote code that humans then ran. After MCP, the agent is the runner — it shells out to the AWS CLI, the gcloud SDK, the database connection string. That shifted the blast radius from "review-the-PR" to "the action already happened."
Approval prompts became theatre
Cursor and Claude Code both ship with "approve every action" toggles. Developers, fairly, hit "approve all" by Day 2. The model's "do you want to proceed?" prompt is not a security control — it's a UX hint. Real authorization had to move to the platform.
Identity tooling started catching up
CIEM and IAM tooling assumed humans. Then service accounts. Now AI agents — which mint credentials, call APIs and die faster than any CIEM can rescan. The market needed something that brokered credentials at the moment of use, not just analyzed policies at rest.
A Coding Agent Firewall is not…
Not a prompt-injection scanner
Prompt scanners watch the conversation. They stop before the agent touches anything outside the chat. A Coding Agent Firewall starts there — it doesn't look at prompts, it looks at actions.
Not an LLM gateway
LLM gateways proxy model traffic — rate limits, token spend, content moderation. They don't see what the agent does after the LLM call, when it picks up the AWS SDK and starts making real API calls.
Not just CIEM with an agent column
CIEM analyzes permissions at rest. A Coding Agent Firewall intercepts the action at runtime. Both useful; entirely different controls.
Not the IDE's built-in approval prompt
"Approve every action?" prompts in Cursor or Claude Code are UX, not security. They cooperate with the developer; they don't enforce against them.

What Our Users Are Saying
Customer Reviews
Cloudanix is trusted by security leaders worldwide to deliver proactive, reliable, and cutting-edge cloud security.
One day, I changed the password of a root account, and my CTO called me within less than a minute to confirm if I did so. I was not expecting a reaction this quick. He told me Cloudanix alerted him of this password change and that he wanted to confirm as it was a critical security notification. I couldn't believe it!
Compliance is one way of staying secure, but what I want is the ability to go deeper and attain 'true security.' Cloudanix provides us the capability to do so.
Cloudanix is building for the future of the cloud, which makes the product all the more desirable.
Cloudanix gave us the visibility we were missing. Being able to move from permanent access to a robust Just-In-Time (JIT) workflow has fundamentally changed our security posture without slowing down our engineering velocity.
We are excited to leverage Cloudanix's comprehensive multi-cloud DevSecOps solution to secure our production workloads on AWS. Cloudanix has demonstrated that it can solve many challenges that DevSecOps teams face while continually adding new features such as SOC2 compliance and drift detection.
Managing third-party partner access was once a major concern for our security posture. With Cloudanix JIT Cloud, we've effectively achieved zero third-party risk. We can now grant access confidently, knowing that it is temporary, audited, and automatically revoked, resulting in a 100% reduction in our privileged access exposure.
The snooze feature and responsible alerts have helped us save time and prioritize what to tackle first.
Implementing Cloudanix JIT internally allowed us to practice what we preach. By eliminating permanent access to our own clouds and databases, we've neutralized the risk of standing privileges, ensuring our own 'keys to the kingdom' are never left exposed.
The problem with permissions is a lot of times, the gaps are left open due to oversights from inside the organization itself. With Cloudanix's CIEM, we get a complete view of user permissions and access. This enables us to update the permissions, reducing the attack surface.
In the world of Fintech, trust is our currency. Cloudanix provided the frictionless visibility we needed to secure our EKS workloads across AWS, ensuring we stay audit-ready for SOC2 and GDPR without slowing down our engineering velocity.
Cloudanix delivered value within 5 minutes of onboarding. Continuous monitoring, timely detection, and excellent documentation helped us attain a great cloud security posture.
Technology strategies and business strategies are in a state of constant change which includes centralization and decentralization of responsibilities. Regardless of strategic shift, we still have intellectual property to protect. Cloudanix are critical partners for us in our public cloud security posture across our three cloud providers.
Cloudanix has been amazing. They opened up a common Slack channel with us — and it feels like we are talking to our own team and getting things done with Cloud security. The support team is always available, friendly, helpful, and ready to go out of their way.
Beyond just access management, Cloudanix CSPM has given us a unified view of our AWS environment. The real-time alerting and anomaly detection allow us to prevent any untoward activity before it happens, which is critical for a marketplace connecting 50+ financial institutions.
For a Fintech company, data is our most valuable — and most sensitive — asset. Cloudanix DAM hasn't just improved our visibility; it has given us control. The ability to mask data and prevent unauthorized queries in real-time is a game-changer for our compliance and customer trust.
Our clients, especially in the Middle East financial sector, demand absolute accountability. Cloudanix JIT Cloud has been a competitive differentiator for us, allowing us to provide secure, governed access to customer accounts that meet their strictest audit and compliance requirements.
Cloudanix is always on my team's lips because of its exceptional support. Be it a small or big query, Cloudanix has gone above and beyond to resolve them. This one's a keeper for us.
For a long-lasting partnership, great support goes a long way. Cloudanix has delivered exceptional support whenever required. Their edge is their team is always ready to go beyond to solve any issues that we have. This speaks volumes about the culture at Cloudanix.
Beyond the technology, Cloudanix feels like an extension of our own team. Their willingness to stand up a dedicated Middle East tenant for us and provide exceptional support at a sensible price makes them a long-term partner for Hugosave.
The real-time notifications that Cloudanix provides are a real lifesaver. Their adaptive notifications ensure that my team stays productive and doesn't get interrupted all the time.
The whole point in technological evolution is to help improve the world we live in. We must protect that and to do so requires an effective and efficient security strategy. The Cloudanix team helped make our public cloud security posture management strategy a reality. The symbiotic relationship we have allows for a continuous feedback loop which is how business should operate.
