PRESS RELEASE

HOUSTON – April 10, 2013 – Alert Logic (www.alertlogic.com), the leading provider of Security-as-a-Service solutions for the cloud, today announced GAAP revenues for the quarter ending March 31, 2013 of $9.5 million, up 45% from the first quarter of 2012, and up 10.6 percent from the fourth quarter of 2012.

All channels recorded strong growth, including Alert Logic's cloud and hosting provider partners and resellers. Alert Logic has more than 2,100 customers using its Security-as-a-Service solutions, both through service providers and directly from Alert Logic.

"Alert Logic has consistently maintained a growth rate in excess of 40% over the past four years as we have broken through the annual revenue levels of $10 million, $20 million, $30 million, and now $40 million," said Gray Hall, Alert Logic's president and CEO.
