Web and e-mail security provider M86 Security was set to announce on Tuesday the acquisition of Finjan.
Finjan brings to the table a secure Web gateway product and software-as-a-service solutions, M86 said in a statement. Under the merger, which is effective immediately, Finjan will maintain a development center and operations in Netanya, Israel.
U.S.-based Finjan SW will remain an independent company to retain its malware detection intellectual property, according to a statement.
M86 was created a year ago with the merger of Marshal and 8e6. In March 2009, the combined company acquired behavioral malware detection company Avinti.
Last week, Cisco Systems said it was buying Web-based security software company ScanSafe. And earlier in October, Barracuda Networks, which makes security appliances, announced its purchase of Purewire, a Web security-as-a-service provider.
Meanwhile, vulnerability management provider Rapid7 recently acquired Metasploit, an open-source penetration testing framework and exploit database.
