Frequently asked questions
Do I need a card for the Free plan?
No. The Free plan is free forever and never asks for payment details.
Can I scan any domain?
Only domains whose ownership you've verified via DNS. It's an ethical and legal gate: Sentra never audits anything that isn't yours or that you aren't authorized to audit.
Does Sentra attack my systems?
No. All scans are passive: we only observe already-public information (headers, TLS, DNS, certificate transparency). We never exploit vulnerabilities or put load on your infrastructure.
Can I cancel anytime?
Yes. No contracts, no lock-in. You manage your subscription from the customer portal and keep access until the end of the paid period.
