AI coding assistant security

Let agents write code.Define what they can reach.

Review the dependencies they install. Set boundaries around credentials and deployment tools. Keep evidence of the actions your controls evaluate.

Check coverage
From a coding task to a security decision

Where routine coding tasks create risk.

Follow a dependency update, a credential request or a release. See where to inspect, where to enforce and what to verify.

The assigned task

Update a dependency.

The new version runs an install script that downloads and executes another payload.

What to check
Inspect the package and installation path before running it. Review known malicious-package findings and source behavior.
Where Oktsec fits
Aguara for local checks; Signal for supported dependency inspection.
What to review
Package version, inspected files, detection rule and the source behind the finding.
Review supply-chain risks

Evaluation scenarios, not customer incidents or live product results.

Coverage follows the integration

Know which actions reach the control.

Choose the connection path before choosing the policy. Confirm the client version and test both allowed and denied actions in your environment.

What happens if a hook cannot reach Node?

Behavior depends on the deployment profile, enforcement mode and client. Default hook failures can allow execution; configured fail-closed behavior can deny block-capable events, while client timeouts still need separate testing. Post-action observations cannot stop an action that already ran. On the hook path, queuing a quarantine item does not itself pause the tool call.

Review the deployment boundary
Start with one team

Make the evaluation answer a real question.

Bring one repository, the coding client and the tools it can reach. Define the permitted task and the action that must be stopped.

Test the connection.

Run allowed and denied requests. Check bypass routes, unavailable services and client timeouts.

Inspect the evidence.

Review the policy and observed result. Identify which events produce logs or signed receipts.

Measure the work.

Record review and investigation time against your current process, using the same scope and outputs.

Before you connect

Questions from engineering and security.

Does connecting an MCP server protect everything the editor does?

No. MCP wrapping covers calls through that connection. Built-in shell commands, file operations and direct API calls require their own supported integration. Discovery alone does not establish enforcement.

Which coding assistants can we evaluate?

Claude Code and Codex have dedicated Node hook connection paths. Cursor, VS Code and other supported MCP clients can route MCP calls through a configured proxy. The evaluation checks the client version, emitted events, mode and failure behavior.

How do Aguara, nanostack and the commercial products fit together?

Aguara is an open-source engine for local supply-chain checks. nanostack organizes development, review, security and QA. Signal offers supported dependency inspection; Control and Cloud provide configured runtime policy and operating evidence. Their capabilities and releases are distinct.

Can we measure the time this saves?

Yes. Agree a baseline and record time spent reviewing a dependency, investigating an exception or preparing evidence. Compare the same scope and outputs during the evaluation. No fixed time-saving claim is assumed.
