Security-as-a-service provider ProofPoint (NASDAQ:PFPT) announced on Friday that it had completed the acquisition of Armorize, a developer of cloud-based anti-malware products. 

ProofPoint paid approximately $25 million cash for Armorize, according to the terms that were originally announced on Aug. 9, for staff that specializes in cloud-based threat intelligence, detection of "zero-day" attacks and unknown vulnerabilities, real-time dynamic threat protection, and advanced malware detection research. Armorize staff includes more than 35 certified ethical hackers.

At the time the deal was announced, ProofPoint CEO Gary Steele said: "We've been leveraging key Armorize technology in our targeted attack protection for almost a year, and the effectiveness has been phenomenal. Acquiring Armorize solidifies Proofpoint's leading position in cloud-based, next-generation threat detection technology and gives us full access to Armorize's world-class malware research expertise."

The acquisition is expected to have an immaterial impact on ProofPoint's revenues and billings during the third quarter and full year of 2013. Proofpoint expects its non-GAAP net loss to increase by approximately $0.5 million, or approximately $0.01 per share, during the third quarter, and by approximately $1.0 million, or approximately $0.03 per share, for the full year, excluding one-time costs associated with the execution of the merger.
