To protect against cybersquatting, brands should consider registering similar domain names to their primary domain, including common misspellings. Implementing a proactive domain monitoring strategy can help identify potential threats early. Legal avenues, such as the Uniform Domain-Name Dispute-Resolution Policy (UDRP), are available to challenge cybersquatters. Additionally, employing email authentication measures like SPF, DKIM, and DMARC helps ensure that emails are genuinely from your brand, safeguarding your reputation.
