Email security is protecting your emails against people who have malicious intentions, want to steal information from you or send false messages. It’s like locking a letter before you send it so that only the right person can open it.

What do SPF, DKIM and DMARC mean?
SPF, DKIM, and DMARC are email authentication methods that help protect against spam, phishing, and email spoofing, which are common cybersecurity threats.
SPF (Sender Policy Framework): SPF is an email authentication method designed to detect forging sender addresses during the delivery of the email. It allows the email domain owner to publish a list of IP addresses or subnets that are authorized to send emails on behalf of the domain. When an email is received, the receiving mail server checks this policy to determine if the email comes from a listed IP address. If not, it can be flagged or rejected.
DKIM is like a signature at the bottom of your email that shows that the email is really from your company and not from someone trying to pretend. It’s like a seal of approval.
In IT terms: DKIM (DomainKeys Identified Mail) is an email authentication method that adds a digital signature to email headers. The signature is generated with a private key based on the content of the message and the sender’s domain. The public key is published in DNS and used by receiving servers to validate the signature and confirm the authenticity of the message.
DMARC is like a security password that helps ensure that the email you receive is real and not fake. It ensures that the email you receive from a company actually comes from that company and not from someone pretending to be that company.
In technical terms, DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy framework used to validate and strengthen the implementation of email authentication standards such as SPF and DKIM. It allows domain owners to define policies for handling emails that do not meet authentication standards, such as rejecting or marking as spam.
Why is this important?
This is important because it helps you know whether an email you receive is genuine or not. It protects you from people who try to trick you or steal your personal information by pretending to be something or someone else.
Email authentication via SPF, DKIM and DMARC can reduce phishing, spoofing and email fraud. DKIM helps prove the sender’s authenticity and ensure message integrity, while DMARC allows the sender to establish policies for dealing with emails that do not meet authentication standards. This increases trust in email communications and helps organizations protect their brand image and protect end users from malicious emails.
What are the risks?
If you don’t have email security, you run the risk of being deceived by fake emails that look real (spoofing). These fake emails may ask you for personal information, whether you want to send money to scammers or install malware on your computer. Unsecured emails also run the risk of interception, which could leak confidential information. The email security techniques SPF; DKIM and DMARC are essential to reduce these risks so you can receive and send emails with confidence.
