After analyzing thousands of SMB security postures, we see the same pattern every time.

The top 3 breach entry points for small businesses in 2026:

1. Unpatched API endpoints

Teams deploy fast and patch slow. Attackers scan exposed endpoints 24/7. If your production config has public-facing APIs with outdated auth or missing rate limiting, you're exposed. Quick check: run nmap -sV against your domain and flag anything responding on unexpected ports.

2. Misconfigured cloud storage permissions

S3 buckets and Supabase storage set to public during dev that never got locked in prod. Shockingly common. Quick check: audit your bucket policies for anything with "Principal": "*".

3. Credential stuffing through reused passwords

Attackers buy leaked credential lists and automate login attempts at scale. If you don't have MFA enforced on every internal tool, you're one breach away from full compromise. Quick check: test your login endpoints with rate-limit tooling in a staging environment.

The difference between companies that get breached and companies that don't isn't budget — it's visibility. You can't fix what you can't see.
