The easiest (and cheapest) way to prevent most cybersquatting is to register a few basic variations of your company name before the damage is done.
Isn't this going to get expensive? Registering protective domain names is now becoming a necessary and expected cost for doing business on the Internet. Luckily the domain registration industry has been recently de-regulated. Domains which have traditionally cost $70 to register can now be registered for about $20. A small price to pay to help protect against the time and expense involved pursuing a cybersquatter.
