The Tel Aviv-based business has backers including Battery Ventures and Blumberg Capital.
Battery joined serial entrepreneurs Ehud Weinstein and Ofir Shalvi to help Cyvera raise $11m of funding last August.
Blumberg Capital led the previous financing round for Cyvera, which attempts to prevent attacks from unidentified online threats by blocking attempts to exploit software or persuade users to unwittingly run malicious files.
The purchase is expected to close in the second half of the 2014 financial year.
