Security code review for every pull request

Enclave reviews pull requests, identifies risky changes, explains the impact on the exact lines involved, and gives developers a ready prompt for their coding agent.

The challenge

Why security review is breaking down

More pull requests and shorter release cycles leave less room for a separate security queue. AI-assisted development can increase code volume, but AppSec bandwidth does not automatically grow with it. A small team needs a review workflow that carries context into the pull request instead of creating another handoff.

Security code review tools for a fast-moving team should help engineers understand a concern while the change is still in front of them. Enclave brings verified security feedback into the review workflow so developers can act before merge, with people retaining control of what ships.

The review

Review the change, not just the codebase

A new endpoint, dependency update, or permission check changes how an application behaves. Reviewing the change means reading the diff alongside surrounding code and dependencies, then asking what the new path allows an attacker to do.

Enclave checks potential concerns before posting review feedback. Its developer-friendly findings connect relevant lines to impact, supporting evidence, and a suggested fix. The goal is a precise explanation an engineer can use, not a longer list of alerts.

The workflow

How Enclave works in a PR workflow

How security reviews fit into a PR workflow: investigate the proposed change, return context where engineers already review it, and leave the shipping decision with the team.

  1. A pull request arrives

    The proposed change becomes the scope for security review, alongside the code and dependencies around it.

  2. Enclave investigates the change

    Agents inspect the diff in context and verify potential security concerns before turning them into feedback.

  3. Findings land on the relevant lines

    Inline comments explain the impact of a risky change and the context and evidence behind the concern.

  4. Developers get a ready prompt

    The comment includes a prompt developers can hand to their coding agent, giving them an actionable starting point for remediation.

  5. Engineers decide what ships

    Your team controls remediation, approval, merge, and deployment. Agents support the work; they do not take over the merge decision.

AI-assisted development

Security review for AI-generated code

Coding agents can produce more changes without removing the need to review them. AI security tools for reviewing pull requests should evaluate the resulting code in context, regardless of who or what wrote it.

Enclave reviews pull requests opened by coding agents as well as engineers. Comments give the developer a ready prompt for their coding agent, while engineers approve the resulting changes. Higher throughput still needs a consistent security review standard.

Choosing a tool

What teams need from a security code-review tool

The best pull request security review tools for your team are the ones that fit its actual review process. Evaluate the feedback and the path to action, not just the number of issues reported.

PR-native feedbackEnclave posts comments and checks in the pull request, keeping security feedback alongside the engineering discussion.
Exact-line findingsA finding points to the changed lines involved so the developer can connect the concern to the proposed change.
An explanation of riskImpact, surrounding context, and supporting evidence help the reviewer understand why the PR needs attention.
A practical route to remediationSuggested fixes and ready coding-agent prompts give developers something concrete to work from.
Coverage for a fast-moving teamAutomated pull request review helps a small team apply security review across changes without relying only on manual AppSec inspection.
Human approval gatesYour engineers review remediation and approve every merge. Security automation does not remove ownership of the change.
Review checklist

Questions to ask before a pull request merges

Use this security review checklist for a pull request to guide the review conversation, whether or not a tool flagged the change.

Inputs and entry points

What new input can reach the changed code, and where does that input go?

Authorization and data access

Do changed permission checks expose data or actions to a user who should not have them? Enclave's code-security agents trace authorization decisions and data flows; review still needs engineering judgment.

Dependencies

Did a package change introduce a vulnerable version, unexpected behavior, or a new lifecycle script?

Impact and evidence

Does the finding explain the affected code, the reachable path, and what an attacker could gain?

Remediation and approval

Is the proposed fix clear, does it address the concern, and has the responsible engineer approved it?

Beyond the pull request

One part of agentic application security

PR review is a checkpoint, not the boundary of application security. Enclave also investigates code, cloud configuration, and running applications, prioritizes confirmed exposure, prepares remediation, and retests attack paths after deployment. Review feedback and post-deploy verification belong to the same broader security workflow.

FAQ

Security code review FAQ

What is security code review?

Security code review examines code changes for weaknesses that could expose data, permissions, or application behavior to an attacker. In a pull request, the useful output connects a concern to the changed lines, explains its impact, and gives engineers a path to remediation before merge.

How is AI security code review different from SAST?

SAST analyzes source code and can flag patterns and data flows during development. Enclave's agents investigate the pull request alongside surrounding code and dependencies, verify concerns, and explain them in the review workflow. Enclave also runs SAST as part of its broader investigations and works with existing scanners; these approaches can complement each other.

Can Enclave review every pull request?

Yes. Enclave reviews every pull request and returns security feedback in the PR workflow. Security tools that review every pull request automatically can help a small team cover changes without manually inspecting each one for security. Engineers still review the findings and decide what merges.

Does Enclave explain why a pull request is risky?

Yes. Enclave comments on the relevant lines with impact, context, supporting evidence, and a suggested fix. A reviewer can see why the change matters rather than receiving only an issue label or severity score.

Can Enclave help developers fix security findings?

Yes. Pull request comments include a ready prompt for the developer's coding agent and guidance on the concern. In the broader platform, agents can also prepare remediation pull requests or infrastructure-as-code changes for engineers to review.

Who approves a fix before it is merged?

Your engineers do. Agents can investigate and prepare changes, but nothing merges without a human. Your team remains responsible for approval, merge, and deployment.

Does Enclave support GitLab pull request security reviews?

Yes. In GitLab, the review unit is a merge request. Enclave supports GitLab merge request security reviews, and it also connects to GitHub and Azure DevOps for code. The review workflow keeps engineers responsible for approving changes.

Can automated code reviews spot authorization bugs?

They can help investigate them. Enclave's code-security agents follow authorization decisions and data flows across components, and PR review examines changes in the surrounding code. That supports investigation of risky permission changes, not a guarantee that every authorization bug will be found.

How long should a PR security review take?

Long enough to establish whether the concern is real and give the developer a useful next step. Review scope and the context needed for verification matter more than an arbitrary timing target. Enclave posts its findings in the pull request itself, so security feedback doesn't wait for a separate queue.

Review every pull request without slowing engineering down.
