Compare automated regression monitoring with deeper periodic human-led accessibility assessment.
This is a category-level operating-model comparison, not a fabricated competitor scorecard. There is no universal winner.
Focused workflow
Alternative operating model
Catch new automated accessibility regressions after site changes without rerunning scans manually.
Periodic accessibility audit is the better starting point when that broader role is the main job you actually need, rather than the narrower workflow described here.
Alert on meaningful NEW/PERSISTING/FIXED state changes so teams can distinguish regressions from known debt. Preserve enough evidence to reproduce the automated finding after a deployment.
Capabilities vary by periodic accessibility audit. Check whether it preserves the evidence, human review and handoff state your team needs instead of assuming the category guarantees it.
Automated evidence requires manual review No claim of WCAG conformance, legal certification or full accessibility audit No accessibility overlay or auto-remediation promise
Periodic accessibility audit may legitimately cover responsibilities this focused workflow does not. Choose it when those responsibilities are required, not because a broader category sounds more complete.

Choose periodic accessibility audit when the narrow problem is not the buying trigger, or when your organisation needs the alternative category as a system of record or primary operating layer.
Choose AccessGuard when the narrow job, evidence model and boundary described above match the immediate operational problem.
Choose Periodic accessibility audit when you need that category's broader responsibility as the main system or service. In some environments both layers are complementary rather than substitutes.
Before buying either option, verify the real data boundary, evidence retention, human approval model, integrations and exclusions against your own workflow.
