Several beliefs about SCA at scale sound sensible and mislead buyers: that more findings means worse security, that one global policy is simplest, that a clean scan means safe software. Each has a kernel of truth and a practical correction. Here are five.
Myth 1: More findings means we got less secure
Fact: Findings rise when coverage rises. The first full scan of an estate nearly always surfaces more than expected, because it sees repos nobody had scanned. Report coverage beside counts, and report new versus inherited findings separately so progress is visible.
Myth 2: One policy for everyone is simplest
Fact: It is simplest to write and hardest to live with. A single strict policy blocks low risk internal tools and teaches developers to bypass. A single loose policy under protects critical systems. A layered model with an org baseline and tighter rules for sensitive units is more work to set up and less work to operate. See how policy inheritance should work.
Myth 3: A clean scan means the software is safe
Fact: A scan is a snapshot of known advisories against a known dependency list. New advisories arrive after the scan, and some dependencies are not visible to static parsing. GitHub's own documentation notes that its graph is built from manifest and lock files, with a submission API for dependencies resolved at build time, which shows even large platforms treat parsing as incomplete by itself (see Sources). Continuous rescans and build time data close the gap. More in a clean scan does not mean your software is safe.
Myth 4: Ownership will sort itself out
Fact: Without routing, findings land in a shared queue and age. Ownership needs a source of truth, such as a service catalog or CODEOWNERS, and a fallback for unowned items. CODEOWNERS itself skips owners that do not exist or lack write access, so even that source needs checking.
Myth 5: Blocking builds is the goal
Fact: Fixing risk is the goal. Blocking is one tool. Programs that start with blocking on legacy debt often get disabled gates and exceptions that never expire. Baseline first, block new high risk findings, then tighten in waves, as in moving SCA from advisory to blocking.
A quick reality table
| Belief | Better framing |
|---|---|
| Count of findings is our score | Coverage, time to fix and overdue items are the score |
| Policy is a document | Policy is data with versions and approvals |
| Scanning happens at build | Scanning happens at build and whenever advisories change |
| Security owns findings | The owning engineering team fixes, security sets the bar |
| Every finding is urgent | Reachable, exploited and exposed findings first |
What to do with this
Use the myths as interview prompts. Ask a vendor how their tool helps a customer avoid each one. A strong answer shows a feature or a report. A weak answer restates the myth in friendlier words.
Safeguard offers reachability analysis, continuous monitoring and policy gates aimed at these problems. You can check coverage and findings on your own code with a free scan at gold.safeguard.sh/scan.

Quick check
Is a higher finding count always bad news?
No. Check what changed in coverage. A new scan of previously unscanned repos adds findings that already existed.
