Imperva, a company that provides application data security, has raised $20 million in a fourth round of financing. The company’s total funding is now $54 million.

We covered the Foster City, Calif.-company back in 2006, when chief executive Shlomo Kramer (who co-founded the successful security firewall company Check Point Software Technologies) told us Imperva stands out because primarily targets database security.

The round was led by Meritech Capital Partners. Previous investors Accel Partners, Greylock VenturesUS Venture Partners and Venrock Associates also participated.
