Sender ID is an email authentication protocol that can prevent email spoofing – a technique by which hackers create the “From” address to make recipients think a message came from a known source. Verifying that an email is sent from a legitimate server ensures your messages are not spam or impersonate a genuine brand.
Although others like SPF (Sender Policy Framework) and DKIM are also engaged in the security of emails, sender ID ensures explicitly that the sender’s IP address is allowed to send emails on behalf of the domain, offering an additional level of security.
Fight back with sender ID
- 91% of all cyberattacks start with an email.
- Companies that implemented sender ID witnessed a 30% decrease in phishing attempts.
- In practice, 88% of emails cause email servers if they pass basic authentication checks like SPF or sender ID.
Why is sender ID still relevant
Sender ID: your email’s digital DNA test that stops sketchy imposters from wearing your company’s face while asking for password ‘confirmations’ from that prince who’s suddenly your long-lost cousin.
Jörgensen’s quote hits the nail on the head – Sender ID is like a secret handshake for your inbox. Without it, spammers crash the party, pretending to be VIPs while slipping phishing scams past security.
Companies being attacked
Acme Corp, a global consulting firm, suffered from email spoofing when their domain was used in a large-scale phishing attack on customers. With the implementation of sender ID, they successfully eliminated the threat. Within three months, they saw a 50% reduction in fake emails in their clients’ mailboxes.
The company included SPF and sender ID to allow their genuine servers to mail on their behalf. Acme Corp even succeeded in drastically improving their mail deliverability. This resulted in a 50% decline in the rate of email spoofing incidents.
On the other hand, GreenTech Solutions, the sustainable technology specialist, faced brand impersonation issues daily. Hackers were impersonating its brand to mislead customers, and trust was lost. They implemented sender ID with SPF and DKIM to protect the brand and reassure clients. They experienced a high increase in client traffic and customer trust improved.
Always be present
Challenge:
One of the common problems in implementing sender ID is ignorance of how it is combined with other protocols like SPF and DKIM. The thinking goes that a single protocol will do, but a layered solution is always preferable. Organizations also occasionally forget to refresh their records, leading to old or incorrect settings.
Resolution:
- Layer your defences: Combine sender ID with SPF and DKIM for an enhanced solution.
- Regular updates: Ensure your DNS records are current to prevent potential exploits.
Using sender ID for better email security
- Ensure your domain’s DNS is configured correctly to incorporate sender ID records.
- Pair the sender ID with SPF and DKIM for maximum security.
- Test whether your emails pass the sender ID tests before sending them out to many people using email authentication tools.
- Regularly check your email deliverability and attempts at spoofing to identify issues early on.
