## Email Security: Phishing Filters, SPF, DKIM & DMARC FAQs

### What is DMARC and do I need it?

DMARC tells other mail servers to reject email pretending to be you. It protects your customers from fake invoices and improves your own deliverability.

### What is the most important cybersecurity step for a small business?

Turn on multi-factor sign-in for email and remote access, and keep backups that ransomware cannot reach. Those two steps stop most real-world attacks.

### Do you help with cyber insurance applications?

Yes. We put the controls insurers require in place (MFA, endpoint protection, backups, training) and help you answer the questionnaire accurately.
