Platform›Code Shield

Security from the first line of code. Not the last.

Code Shield is O3's developer-layer security product — IDE extension, PR gate, and CI scanner unified into one engine. The same reachability analysis runs everywhere, so findings are consistent and actionable from the moment you start typing.

Capabilities

One engine. IDE, PR gate, and CI.

The same reachability analysis everywhere means no finding discrepancies between environments.

VS Code + JetBrains IDE extension

Security findings appear inline as you type — not as a separate scan step hours later. Supports VS Code, IntelliJ IDEA, PyCharm, GoLand, WebStorm, and all JetBrains IDEs.

Reachability-based SAST

Static analysis that understands whether a vulnerable code path is actually reachable at runtime. No more triaging hundreds of false positives — you see what's exploitable.

Impact-aware SCA

Software composition analysis that combines dependency vulnerability detection with function-level reachability — only surfacing CVEs where the vulnerable function is actually called.

Secret detection

Detects API keys, tokens, credentials, and private keys committed to repositories — with entropy-based detection, pattern matching, and verified-active secret identification.

PR security gate with inline comments

Blocks pull requests when new security findings are introduced. Findings are posted as inline review comments with context, severity, and fix guidance directly in the diff.

CI/CD integration (GH Actions, GitLab, Jenkins)

Native plugins for GitHub Actions, GitLab CI/CD, Jenkins, CircleCI, and Azure DevOps. Same engine, same findings, whether triggered from IDE, PR, or pipeline.

Reachability Engine

95% of SAST findings are noise. Code Shield shows you the 5% that matter.

Traditional SAST tools flag every potential vulnerability regardless of whether vulnerable code is reachable in your execution environment. Code Shield traces call graphs from entry points to vulnerable sinks — and only reports findings where the path is real.

Everything teams ask before rolling this out. Still stuck? Reach our team.

  • Reachability-based SAST (Static Application Security Testing) only reports vulnerabilities where the vulnerable code path can actually be reached from a real application entry point at runtime. Traditional SAST reports all potential vulnerabilities regardless of whether they are reachable, producing false positive rates of 85% or more. Reachability analysis traces call graphs from HTTP handlers, CLI entry points, and event listeners to vulnerable sinks, eliminating the noise and letting developers focus on findings that are genuinely exploitable.
  • Code Shield installs as a standard IDE extension available in the VS Code Marketplace and JetBrains Plugin Repository. Once installed, it authenticates with your O3 organization and begins scanning files as you edit them. Findings appear as inline diagnostics, wavy underlines with severity indicators, with hover tooltips showing the vulnerability description, CWE reference, and suggested fix. No separate scan step is required.
  • Impact-aware SCA (Software Composition Analysis) combines dependency vulnerability detection with function-level reachability analysis. Instead of reporting every CVE in every dependency, it determines whether the specific vulnerable function in the dependency is actually called by your code. A vulnerability in a logging library that only affects a code path you never execute is deprioritized. Only CVEs where the vulnerable function is reachable in your application are surfaced as actionable findings.
  • Code Shield's PR gate integrates with GitHub, GitLab, and Bitbucket as a required status check. When a pull request introduces new security findings, the gate fails and blocks merge. Findings are posted as inline review comments on the specific lines of the diff where the vulnerability appears, with severity, CWE classification, and fix guidance. Existing findings from the base branch do not trigger failures, only net-new issues introduced by the PR.
  • Yes. Code Shield's secret detection uses a combination of high-entropy string detection, pattern matching against known API key formats (AWS, GCP, Azure, GitHub, Stripe, Twilio, and 200+ others), and verified-active checks for select providers. It runs in the IDE before secrets are ever committed, and again in the PR gate and CI pipeline. When a high-confidence secret is detected, it flags the exact line with the key type identified.
