Log-data-analysis and -retention appliance maker LogLogic Inc. and managed E-mail-security and spam-services provider MX Logic Inc. each raised $11 million in equity funding Monday.

This summer LogLogic unveiled a line of appliances that help companies better manage their efforts to stay in compliance with such regulations as Sarbanes-Oxley and the Health Insurance Portability and Accountability Act.

The company's "LX" appliances collect performance and event information from devices such as servers, network switches, and firewalls. The collected information can then be analyzed to spot potential security, performance, and compliance problems. The company also makes a line of "ST" appliances, which offer archival log storage of up to 20 terabytes.

This is LogLogic's second round of funding this year. In April, the company revealed a series A round worth $5.5 million, bringing its total investment to $16.5 million. This round included investments from Sequoia Capital, Telesoft Partners, and Worldview Technology Partners.

MX Logic provides E-mail security services that block spam, viruses, and E-mail worms. MX Logic competes with other E-mail security providers such as FrontBridge, Mailblocks, MessageLabs, Postini, and Symantec.

MX Logic's $11 million round was led by UV Partners.
