3 PROTECTING WINDOWS COMPUTERS REVIEWER’S GUIDE
SOPHOS CLIENT FIREWALL
Sophos Client Firewall is integrated into the endpoint agent making
deployment, configuration, updating, and management by Enterprise Console
simple. It proactively locks down computers, protecting against known
and unknown threats, such as internet worms, hackers, and unauthorized
application communication. Features that prevent application hijacking and
impersonation ensure Sophos Client Firewall delivers better protection than the
simple port blocking firewalls offered by many other security vendors.
Zero-day protection against known and unknown threats
Sophos Client Firewall provides zero-day protection, i.e. it blocks the window
of vulnerability that exists between a new threat emerging and protection being
deployed. It defends all corporate computers from complex and rapidly spreading
threats and prevents outbreaks before they can disrupt business continuity.
Proactive lockdown
Sophos Client Firewall protects against network and internet worms,
hackers, and the risk of unprotected computers connecting to the network,
by proactively locking down computers—both those in the office and laptops
connecting via wireless hotspots and hotel broadband connections.
Port tracking and blocking to eliminate threats
Sophos Client Firewall stops known and unknown threats by tracking active ports
and closing all inactive ports, ensuring that internet worms and hackers are blocked.
Stealth technology – preventing intrusion by hackers
Cybercriminals, such as hackers, use port scanning to identify and target
vulnerable computers with open ports. They do this by sending out connection
requests across the internet. Sophos’s stealth technology prevents computers
from responding to these requests, hiding a computer and making it appear
inactive to the outside world. This gives you an additional level of protection,
ensuring privacy by eliminating the opportunity for hackers to identify and
target vulnerable computers.
