(NASDAQ: CHKP).

eSafe 5 is Aladdin’s award-winning, gateway-based antivirus, spyware control, Web browsing security and application filtering solution. Recognized by the industry as a leader in proactive security, eSafe provides organizations with truly integrated content protection. eSafe 5 received OPSEC certification after meeting rigorous standards validated by Check Point’s thorough interoperability testing.

Customers will enjoy the benefits of simplified management and quicker detection of potential problems.
