Is this scan safe? Are you storing my password?

Absolutely safe. We only check public data — dark-web breach databases (which contain emails leaked from past hacks) and public DNS records for your domain. We never ask for, see, or store any password. The scan is non-intrusive and won't trigger any security alerts on your network.

What does the exposure score actually mean?

It's a 0–100 measure of how much an attacker can learn about your business from public sources alone. We weigh dark-web breach exposure (50 points), missing DMARC anti-spoofing protection (25 points), missing SPF email authentication (15 points), and missing MX/email hosting records (10 points). Most Omaha businesses score between 30 and 70 on first scan.

Why does my business email being in a breach matter?

If you (or anyone in your company) ever reused that password on another service, attackers already have a working login to that service. They use those credentials to break into M365, Google Workspace, banking portals, payroll systems — and to send convincing phishing emails to your team using compromised internal accounts. Reused passwords are the #1 cause of small-business ransomware in 2026.

What's DMARC and why is it the biggest risk?

DMARC is a DNS record that tells the world's email servers what to do with email pretending to come from your domain. Without DMARC, an attacker in another country can send a perfect-looking email from 'you@yourcompany.com' to your customers, vendors, or accounting team — and Gmail/Outlook will deliver it. This is how wire-fraud and CEO-impersonation scams work. Most Omaha small businesses don't have DMARC configured.

Quick Answer

What can hackers see about my business right now?

Without logging into anything, attackers can see whether your business email shows up in dark-web password breaches, whether your domain has SPF and DMARC records (anti-spoofing), what subdomains and services you have exposed publicly, and whether anyone is registering lookalike domains to phish your customers. This free Omaha-built tool checks all of that in 30 seconds — no password, no login, no intrusion. The output is a 0–100 exposure score plus a branded PDF report you can share with your team.

Why It Matters

Why every Omaha business owner should run this scan

In 2026, the average attacker doesn't break in — they log in. They buy a list of leaked email/password combinations from a previous breach, try them against Microsoft 365 and Google Workspace, and once they have a foothold inside one user's mailbox they send invoice-fraud emails to your customers from your real domain. The whole attack costs them about $20 and takes a weekend.

This free tool checks the four public-data points an attacker uses before targeting your business:

Dark-web breach exposure — has your business email been leaked in a past hack? If yes, attackers may already have a working password.
SPF email authentication — without it, anyone can send email pretending to be your domain.
DMARC anti-spoofing policy — the single biggest gap in small-business cybersecurity. Without DMARC, your customers receive perfect-looking phishing emails "from" you.
Email hosting (MX) sanity — confirms your domain is correctly configured for email and not abandoned/hijackable.

All four checks run in 30 seconds against public data only. We never ask for a password, never log into anything, and never trigger a security alert on your network.

After the scan, you'll see your full report immediately — no email gate, no pop-up. If you want help fixing what we find, you can request a free 30-minute call with a local DME cybersecurity specialist. Otherwise, just bookmark this page and re-scan in 90 days.
