What is One-off vulnerability scan?
A one-off (or periodic) vulnerability scan runs at a point in time and produces a snapshot report. No ongoing alerts or history between scans.
Comparison at a glance
| Aspect | Barrion | One-off vulnerability scan |
|---|---|---|
| Frequency | Ongoing (e.g. daily/weekly), alerts on change | Single run or manual re-runs |
| Gaps | Catches drift and new issues between scans | Issues that appear after the scan are missed until next run |
| Evidence | Scan history and trends, audit-ready over time | Single report, no built-in history |
| Effort | Set once, automated thereafter | Run when you remember or schedule manually |
| Best for | Ongoing assurance, compliance, regression | Quick check, pre-launch snapshot, or ad-hoc validation |
| Continuous AI pentest, checked against the live app | Yes. AI agents test your app on a schedule or on demand, and findings are checked against the live app before the report | No. A one-off scan is a snapshot and doesn't try to exploit what it finds |
Who Barrion is best for
Teams that want to catch misconfigurations and drift as they happen, maintain audit-ready evidence, and avoid gaps between manual scans. Ideal for continuous assurance.
Who One-off vulnerability scan is best for
Teams that need a one-time snapshot (e.g. before a launch or contract) or run scans manually on a schedule and don't need automated alerts or history.
Frequently asked questions
Is Barrion a replacement for One-off vulnerability scan?
Barrion does both. You can run a one-off free scan to get an immediate snapshot, and you can enable continuous monitoring if you want ongoing coverage, alerts, and history. The one-off mode covers the quick check use case, and continuous mode replaces the need to remember to re-run scans.
Can I use Barrion and One-off vulnerability scan together?
Yes, this is a natural pattern. Run a one-off scan when you need a snapshot (e.g. before a launch or contract), and run Barrion continuously between snapshots to catch drift and new issues without waiting for the next manual scan.
How is Barrion priced vs One-off vulnerability scan?
Barrion has a free plan that covers one-off scans with core checks. Paid plans add continuous monitoring, alerts, and exportable history. One-off scans from other tools are often free or low-cost but do not include ongoing coverage.
Does Barrion test in production safely?
Yes. Barrion uses passive, read-only checks that are safe to run continuously in production. Whether you run a single scan or scheduled scans, the checks are read-only and built for production.
Summary
Continuous monitoring reduces the risk of issues going unnoticed between scans. Use one-off scans for quick checks or when you don't yet need ongoing coverage. Barrion gives you both: run a free one-off scan to start, then enable continuous monitoring when you're ready.
