Many companies own 5-10 domain names, but only actively use 1-2 for sending emails. Even though you may not be sending emails from all your domains, it's still important to protect them. Here's why: DMARC: Email Security Essentials Think of your domains like your online identity. Criminals can exploit unprotected domains to send fake emails (phishing) that appear to come from your company. This can damage your reputation and lead to financial losses for your customers. DMARC helps prevent this by verifying that emails that appear to come from your company are actually legitimate. How it works: SPF: A list of authorized servers allowed to send emails on behalf of your domain. DKIM: A digital signature that verifies the email truly originated from your domain. DMARC: Combines SPF and DKIM and tells the recipient's email system what to do with emails that fail these checks (e.g., send to spam or reject). Unprotected domains are vulnerable: Even if you only send emails from your .com address, criminals can still abuse your unused .net or .org domains to send phishing emails. This damages your overall domain reputation, making it harder for your legitimate emails to reach your customers' inboxes. Protecting your domains benefits everyone: By securing your domains with DMARC, you not only protect your own reputation but also contribute to a safer online environment for everyone. There are options available to deactivate or block sending from unused domains. Let's work together for a better internet. Hvorfor vi anbefaler bedre e-mail sikkerhed: Mange virksomheder ejer 5-10 domænenavne, men bruger kun 1-2 aktivt til at sende e-mails. Selvom du måske ikke sender e-mails fra alle dine domæner, er det stadig vigtigt at beskytte dem. Her er hvorfor: DMARC: Essentiel e-mail sikkerhed Tænk på dine domæner som din online identitet. Kriminelle kan udnytte ubeskyttede domæner til at sende falske e-mails (phishing), der ser ud til at komme fra din virksomhed. Dette kan skade dit omdømme og føre til økonomiske tab for dine kunder. DMARC hjælper med at forhindre dette ved at bekræfte, at e-mails, der ser ud til at komme fra din virksomhed, faktisk er legitime. Sådan fungerer det: SPF: En liste over autoriserede servere, der har tilladelse til at sende e-mails på vegne af dit domæne. DKIM: En digital signatur, der bekræfter, at e-mailen virkelig stammer fra dit domæne. DMARC: Kombinerer SPF og DKIM og fortæller modtagerens e-mail-system, hvad de skal gøre med e-mails, der ikke består disse kontroller (f.eks. sende til spam eller afvise). Ubeskyttede domæner er sårbare: Selvom du kun sender e-mails fra din .com-adresse, kan kriminelle stadig misbruge dine ubrugte .net- eller .org-domæner til at sende phishing-e-mails. Dette skader dit overordnede domæneomdømme, hvilket gør det sværere for dine legitime e-mails at nå dine kunders indbakke. Beskyttelse af dine domæner gavner alle: Ved at sikre dine domæner med DMARC beskytter du ikke kun dit eget omdømme, men bidrager også til et sikrere online miljø for alle. Der er mulighed for at deaktivere eller blokere afsendelse fra ubrugte domæner. Lad os arbejde sammen for et bedre internet.
