Common questions

Is the free assessment really free?

Yes — completely free, no obligation. We scan your external attack surface and deliver a report with findings and recommendations. No credit card, no auto follow-up.

What do you scan?

Email security (SPF, DKIM, DMARC), website vulnerabilities, SSL/TLS, DNS hygiene, and exposed services. It's non-invasive — we only look at what's already visible to attackers.

How quickly will I hear back?

Most inquiries get a response within 4 hours during business hours. Book a call via Calendly for a guaranteed time slot.

Every day you wait is another day exposed.

Find out where you stand — before someone else does.
