Rapid threat management and diverse technology integration for effective monitoring
Expel has made it easier for companies to monitor and manage various log sources. With its vast integration portfolio, customers can efficiently monitor diverse environments. Time to value is quick, as Expel can turn their service up very rapidly. They have both automated active responses and human processes that quicken threat resolution.
