Comparisons SecurityScanner.dev
SecurityScanner.dev alternative — bundle extraction vs. reading the schema
SecurityScanner.dev is an external scanner with the deepest technical surface in this market: 80-plus modules, a Nuclei-backed CVE sweep, OWASP mapping, prompt-injection probes, CI/CD webhooks, Slack and Discord alerting, an MCP server and a Claude skill. Its Supabase work is genuinely clever — it pulls table names out of the JavaScript bundles your site serves and probes each one with your anon key to see which answer. It also performs authenticated IDOR testing. What it does not have, anywhere in the product, is a connection to your repository.
Where SecurityScanner.dev wins
This is the most capable scanner on this page and it beats us on several axes at once: Nuclei's CVE corpus, authenticated IDOR testing, OWASP mapping, CI/CD webhooks and chat alerting are all real, all shipped, and all things we either do not do or have declared out of scope. Their AI triage pass against false positives is the same instinct our corpus gate serves. If you want maximum coverage against a running app and you are willing to triage a larger report, they are the stronger tool.

Choose SecurityScanner.dev if
- You want a CVE sweep across the whole surface, not four targeted checks.
- Authenticated IDOR testing against your running app is the thing you actually need.
- You want OWASP category mapping for a report someone else will read.
- You want findings pushed into Slack or Discord and hooked into CI.
- You do not have repository access to give — it is not your codebase.
Choose Sentris if
- Your table names come from your migrations, not from whatever survived minification into a bundle.
- A table that exists but is never named in client JavaScript is invisible to bundle extraction and visible to us.
- You want the RLS policy read, not inferred from whether a request returned rows.
- You want the migration caught in the branch, before there is a running app to probe.
- You want a published price before you start.
Questions
They already probe Supabase RLS. What does reading the repository add?
The list of tables. Their probe can only test tables it can name, and it gets those names by extracting strings from the JavaScript bundles your site serves. That works well for tables your frontend queries directly, and not at all for a table only ever touched by a server route, an edge function or a background job — which is exactly the sort of table that ships without RLS because nobody was thinking about the browser when they wrote it. We get the list from your migrations, so the set we test is the set that exists.
Is bundle extraction a hack?
No — it is the correct move when you do not have the schema, and it is a well-built one. It is worth naming plainly, though, that it is a workaround for missing information rather than a different way of getting the same information.
What does SecurityScanner.dev cost?
There is a free scan. Beyond that the vendor does not publish a price list on the public site as of August 2026, so we are not going to guess at one here.
One number nobody else on this list publishes
False-positive floods are the standing complaint about this whole category, and not one tool in it states its rate. Ours is precision 1.000, recall 1.000 over 24 planted findings in 9 repositories — with the date, the commit, the scoring rules and the command that reproduces it, plus a paragraph on why 9 repositories is a small corpus. Measured 2026-08-03.
