Computer threats like malware, phishing attacks, and malicious web sites are a problem for businesses. They cost time and money and divert technical
resources from other activities that could benefit a company, so they extract a double penalty.
Although news stories about computer vulnerabilities often focus on hacker attacks on servers and networks, a far bigger problem for most companies is endpoint security—protecting users and their devices against an increasingly complex threat environment. Experts have known for years about the
need to protect client machines from attacks. There are many software and hardware packages available to help combat the problem, including typical solutions such as endpoint security, gateway-based Web security, email security, and virtual private networks (VPNs).
