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.
