DMARC & BIMI: Implementation Steps to Secure Your Brand<\/h4>

We saw the risks of brand impersonation in our\u00a0previous blog<\/a>, but how do we implement it. While\u00a0DMARC and BIMI are essential defenses, their successful deployment requires a structured approach<\/strong>. Many organizations struggle with technical configurations, DNS record management, and cross-department collaboration. Without proper execution, even well-intended security measures can fail.<\/p>

Today we break down the\u00a0technical implementation of DMARC and BIMI<\/strong>, covering critical steps like SPF and DKIM alignment, setting DMARC policies, obtaining a Verified Mark Certificate (VMC), and publishing BIMI records.<\/p>

Additionally, IT teams often face challenges such as\u00a0misconfigured email authentication records, fear of blocking legitimate emails, and the complexity of BIMI adoption<\/strong>. We\u2019ll explore these obstacles and provide practical solutions to ensure a smooth transition to a stronger brand protection strategy.<\/p>

Technical Implementation<\/b><\/h5>

Setting up DMARC and BIMI for your organization requires coordination between IT and domain administrators (and a touch of marketing for the logo aspect). Below are 10 easy steps to get these protections in place:<\/p>

  1. Configure SPF and DKIM:<\/b>\u00a0Start by ensuring your domain has a valid SPF record and that all your email senders (including third-party services) are signing messages with DKIM. These are prerequisites \u2013 DMARC builds on them to authenticate email sources.<\/li>
  2. Publish a DMARC record (monitoring mode):<\/b>\u00a0Add a DNS TXT record for DMARC (e.g. _dmarc.yourdomain.com). Initially set the policy to\u00a0p=none<\/b>\u00a0to monitor email flows without impacting delivery. Specify an email address in the DMARC record (rua tag) to receive aggregate reports. You will need a DMARC Analyser from AmbiSure Technologies to help read these .xml format reports<\/li>
  3. Analyze reports and tighten policy:<\/b>\u00a0DMARC Analyser platform suggested by AmbiSure Technologies will aggregate reports to show which IP addresses and services are sending emails claiming to be from your domain. Review these reports to identify legitimate senders that need SPF\/DKIM alignment, as well as any fraudulent sources.<\/li>
  4. Expert Team at AmbiSure will help you gain confidence that all legitimate email is authenticated, ramp up the policy to\u00a0p=quarantine<\/b>\u00a0(to flag or spam-folder unauthorized emails) and eventually\u00a0p=reject<\/b>\u00a0(to outright block them). This phased approach ensures business emails aren\u2019t accidentally blocked during the transition.<\/li>
  5. Achieve full DMARC enforcement:<\/b>\u00a0Once your DMARC policy is at quarantine or reject for a few weeks with no issues, you have achieved enforcement. At this stage, your brand is significantly safer from direct domain spoofing. You can now leverage this security success for BIMI.<\/li>
  6. Prepare your BIMI logo:<\/b>\u00a0Work with your design or brand team to obtain an SVG version of your official logo that meets BIMI specifications (square, simple background, etc.). Many organizations use a simplified logo mark for clarity at small sizes. Ensure the logo is trademarked, as you\u2019ll likely need proof of ownership.<\/li>
  7. Obtain a Verified Mark Certificate (VMC):<\/b>\u00a0For BIMI, purchase a VMC from a certification authority facilitated by AmbiSure Technologies. We will help you verify your rights to the logo (usually requiring a registered trademark). They will issue a certificate tying your domain to that logo. While a VMC involves some cost and paperwork, it\u2019s crucial for Gmail and future-proofing your BIMI deployment.<\/li>
  8. Publish the BIMI DNS record:<\/b>\u00a0In your DNS, add a BIMI TXT record (default name default._bimi.yourdomain.com). This record will contain a URL pointing to your SVG logo file, and if you have a VMC, it will include a pointer to that certificate (the a= tag with a URL to the VMC file). For example: v=BIMI1; l=https:\/\/yourdomain.com\/logo.svg; a=https:\/\/yourdomain.com\/logo.vmc;.<\/li>
  9. Test and validate:<\/b>\u00a0Use available BIMI inspectors or tools to check that your BIMI record is correctly set up. Send test emails to Gmail, Yahoo, or other BIMI-supporting mailboxes (preferably with a subject line indicating it\u2019s a test). Verify that your logo appears next to the email in the inbox. Gmail\u2019s tool or third-party BIMI inspectors will also confirm if your SVG and VMC are valid.<\/li>
  10. Monitor ongoing performance:<\/b>\u00a0Even after setup, keep an eye on DMARC reports for any new unauthorized sending attempts. Also, watch for any issues in logo display. BIMI doesn\u2019t impact delivery, but if your logo ever stops showing, it could indicate an authentication issue to investigate. Regularly review and renew your VMC (they typically last a year) so that your BIMI status remains active.<\/li><\/ol>

    By following these steps, an organization can go from having no protection to having a robust DMARC policy and a visually authenticated email presence.<\/p>

    Remember, DMARC enforcement is the foundation \u2013 without it, you can\u2019t deploy BIMI<\/b>.<\/b><\/h6>

    Many companies have choosen to use DMARC Analyser suggested & implemented by AmbiSure Technologies to ease the process, especially in large, complex environments. The effort is well worth it, as you\u2019ll dramatically reduce phishing risk and make your communications more trustworthy.<\/p>
