Amazon CodeGuru Security vs KeyDrift
AWS’s application-security service reviews code/IaC in CI with AWS-flavored findings.
AWS-native findings plus low-noise reputation make it credible inside AWS estates.
This page compares the two honestly: strengths credited specifically, differences traced to structure rather than quality, and a decision rule at the end. Verified August 2026.
What Amazon CodeGuru Security does well
Documented scope covers security findings for Java/Python etc. via CI integration and API.
- Deep AWS-service finding relevance.
- Managed scaling within AWS tooling.
- Source code via CI/API submissions.
The gap KeyDrift fills: the deployed bundle
The structural difference is the artifact under inspection. Amazon CodeGuru Security watches inputs to the build — commits, branches, configuration. KeyDrift watches the output: the HTML and JavaScript a browser downloads from the live URL. Build-time substitution, agent-written client calls and streamed payloads live in that output and in none of the inputs, which is why a green Amazon CodeGuru Security report and a leaking deployment can coexist without anyone being wrong.
- Fetched-and-diffed scanning of live URLs, including chunks reachable only through route manifests.
- Streamed server data (
self.__next_f.push,window.__NUXT__) read as carefully as chunk files. - Calibrated dispositions: Supabase anon keys, publishable keys and Firebase web keys recognised as public-by-design instead of reported as leaks.
- Drift transitions — created, regressed, resolved — so a reintroduced key alerts as a regression, not as news.
Feature-by-feature
- Surfaces scanned. ML/heuristic hybrid per AWS papers. versus KeyDrift: deployed web artifacts fetched live, or pasted bundle source for anything behind a login.
- Detection approach. Findings dashboards within AWS consoles. versus KeyDrift: 21 secret detectors across 13 providers with placeholder rejection, alphabet-normalised entropy, payload decoding and a confidence floor below which matches are dropped rather than caveated.
- Change over time. AWS-account enablement. versus KeyDrift: scheduled scans diffed into created/regressed/resolved with alert routing to email, Slack, Discord and webhooks.
- Getting started. AWS-centric development teams. versus KeyDrift: paste a URL at /scan — free, no account — or paste source for private surfaces.
Side-by-side
Every cell below states a specific capability. Where Amazon CodeGuru Security documents more detail than fits here, follow their docs; where KeyDrift claims something, it is verifiable in a two-minute free scan.
| Capability | Amazon CodeGuru Security | KeyDrift |
| --- | --- | --- |
| Primary surfaces | ML/heuristic hybrid per AWS papers. | Deployed web artifacts fetched live: HTML, all chunks (incl. route-manifest-only), streamed payloads |
| Build-time substitution (NEXT_PUBLIC_/VITE_) | Source-side only — substitution happens after these scans complete | Detected in served output — exactly where it lands |
| Hydration payloads (self.__next_f.push, window.__NUXT__) | Outside source-scan scope | Read as carefully as chunk files |
| Public-vs-secret calibration | Varies by engine; anon-key false positives remain the classic complaint | Dispositions built-in: anon/publishable/Firebase-web reported informational, sample keys rejected by name |
| Change over time | AWS-account enablement. | Scheduled scans diffed into created/regressed/resolved; regression alerts name comebacks |
| Alert routing | AWS-account enablement. | Email · Slack · Discord · raw webhooks with per-destination severity thresholds |
| Getting started | AWS-centric development teams. | Paste any URL at keydrift.dev/scan — free, no account; paste-source mode for behind-login surfaces |
| Privacy of findings | Varies by vendor | Masks + salted fingerprints only; no column anywhere can hold a live secret |_Cells describing Amazon CodeGuru Security summarize their public documentation as of the verified date above._
Where each one wins
- Amazon CodeGuru Security wins when Cloud-configured secrets are adjacent-but-different from bundle-published ones; both deserve watchers.
- KeyDrift wins when the question is “what credentials can strangers retrieve from this deployment right now?” — live fetching, calibrated dispositions, and regression alerting without agents installed.
Switching from Amazon CodeGuru Security
Teams arriving from Amazon CodeGuru Security usually keep their existing setup and add one job: point KeyDrift at production, staging, and preview URLs. First week looks like this — day one, run the free scan on every deployment and triage findings by severity; day two, fix or schedule fixes using the linked guides; day three onward, monitoring watches for regressions while Amazon CodeGuru Security continues doing what it does best.

Decision rule
- Keeping Amazon CodeGuru Security for its documented strengths makes sense — it earns them.
- Add KeyDrift when deployment truth matters: post-build artifacts, preview URLs, and reintroduction watch on a schedule.
_Compared against Amazon CodeGuru Security documentation and pricing as verified August 2026. Capabilities change; check their site._ Amazon Web Services and associated marks are trademarks of Amazon Web Services, referenced for identification and descriptive comparison.
Bottom line: choose Amazon CodeGuru Security for its category strengths without hesitation. Choose KeyDrift the moment someone asks what your bundles expose — then keep both, because they were never competing for the same job.
How teams actually run Amazon CodeGuru Security and KeyDrift together
In practice the pairing is boring in the best way: Amazon CodeGuru Security stays authoritative for whatever it was built to do, KeyDrift runs on a schedule against every public deployment, and alerts route into the same channels your team already reads. Nothing is migrated; nothing is turned off. The only new habit is reading one more alert type — and that one arrives masked, classified, and linked to a fix guide.

Common questions
Is Amazon CodeGuru Security bad at security?
No — the page credits specific strengths above. The difference is which artifact gets inspected, not effort or care.
Pricing comparison?
Their list pricing lives on their site and changes; ours sits on the plans page with findings visible free at every tier. Numbers go stale; philosophy does not.
