I used to work at Stonesoft, a company which was back then selling a high-availability extension for Check Point's firewall (http://bit.ly/ivZ22L http://bit.ly/ivZ22L). A really lucrative business, especially as Check Point's existing customers were an easy market to sell to. Then one day Check Point released their own high-availability solution. Stonesoft hasn't been profitable in the approx. 10 years since.
