Cyber Security Firm F-Secure Acquires Little Flocker

Little Flocker, the most advanced security technology available for Macs, has been acquired by F-Secure. The cyber security firm aims to use Little Flocker’s technology to enhance its corporate and consumer macOS security solutions.

For those who aren’t aware, Little Flocker protects Macs by using advanced behavioral based analysis, and monitors apps that attempt to access confidential files and system resources. Interestingly enough, the app was created by security researcher Jonathan Zdziarski, who took a job with Apple last month.

F-Secure will build Little Flocker’s next-generation security engine, which can also detect and block Mac ransomware, into its new XFENCE technology, which will complement F-Secure’s existing endpoint solutions to provide advanced behavioral Mac protection for its customers.

“Macs have become an appealing entry point for attackers seeking to penetrate organizations. With Little Flocker’s technology, we will enhance the behavioral blocking capabilities in our Mac endpoint protection to stop modern adversaries cold”, said Mika Stahlberg, Chief Technology Officer at F-Secure.

The myth of Macs not requiring protection against ransomware, backdoors and other software vulnerabilities is fading away. Advanced persistent threat actors are increasingly focusing on Macs due to Apple’s popularity among senior-level employees and other high-value targets. By acquiring Little Flocker’s core technology and implementing it into F-Secure’s endpoint protection portfolio as XFENCE, F-Secure will further enhance its products’ existing cyber security capabilities for the sophisticated detection of zero-day attacks, regardless of the platform customers choose.

F-Secure XFENCE will be available via a free technology beta at
