If you’re absolutely paranoid about brand control, you need to secure your domain and other TLD variations (if you’re a global empire, ccTLD too). I think that’s a given if you’re an entity concerned about managing your online reputation.
While cybersquatting (or domain squatting) as a business model works, it’s a cat-and-mouse game. But if I could get away with owning a major Philippine telco domain name (I’ve since sold it), that tells you how iffy intellectual property law implementation is here in the country. Brand managers should pull out their credit card now and start buying unregistered domains close to their brands. If you’re doing this now, consider yourself spanked. No online-aware brand manager ever releases a brand or an advertising campaign without buying the best brandable domain for it weeks, if not months, before roll out.
If you’re working on a limited budget consider getting the .NET and .ORG to go with the .COM you already have. If you’re doing a Philippine-based campaign, buy all three plus the .COM.PH and .PH variations.
