Why do companies register TLDs they don't use?

Companies often register private Top-Level Domains (TLDs) as a precautionary measure to prevent others from using them, even if they don't plan to use them immediately. This practice is known as 'domain name defensive registration.' It helps protect a company's brand and prevents potential cybersquatting or phishing attacks. Additionally, registering a private TLD can be a strategic move for future-proofing, as it allows companies to potentially use the TLD if their business needs or branding strategies change.
