Common questions
Every scheduled scan runs the same 80+ checks as a manual scan. After each scan, ZeriFlow compares the new score to the previous one. If the score drops by any amount or a specific check fails for the first time, an alert is sent to your configured channels immediately.
Scheduled monitoring scans are separate from your manual scan quota. Your monthly advanced scan allowance only counts when you manually trigger an advanced scan. Monitoring runs quick scans automatically and does not consume your manual quota.
Yes. Pro allows up to 5 URLs, Business up to 15, and Unlimited has no limit. You can add or remove URLs at any time from your dashboard.
Weekly scans (Pro) run once every 7 days. Daily scans (Business & Unlimited) run every 24 hours. Daily monitoring is recommended for production sites where deployments happen frequently.
Alerts are sent whenever your score drops below the previous scan's score. A score threshold feature (alert only when below X) is on the roadmap for Q3 2025.
