As businesses grow, introducing new technologies into the fabric of internal and remote computing to allow company employees the ability to extend functions into any feasible situation increases the demands on network security to protect company assets. Network security software, often viewed as a control mechanism, is actually a facility that enables technology and business features to extend outside the confines of the business firewall, where new opportunities exist to satisfy and attract new customers. Extending network security software to the enterprise (the entire business organization), whether it's a global multi-organization or multi-currency entity, can represent significant financial expenditures in terms of licensing and implementation. As a result, companies are reluctant to look at alternatives, fearing licensing will put these options out of reach or that hidden costs will hamper any real gains from switching to a new vendor. In the case of antivirus and anti-spam, realistic cost savings options do exist to reduce the overhead of providing these network security tools to every desktop within the confines of the company firewall and also to outside devices in the mobile computing environment. Such per-device enterprise or unlimited-user licensing models augment the investment in antivirus and anti-spam tools. New generation antivirus and anti-spam tools extend not only to remote laptops and desktops but also to smartphones, making the scope of protection on IP-based devices even greater than traditional desktop-based network security applications. Scanning both inbound and outbound IP traffic so that addresses can be blocked and allowed in both directions, these modern network security software tools integrate best-of-class spam recognition methodologies, whereas a single-vendor approach can easily broken. Integration with mail server technologies from multiple manufacturers is also supported by these new technologies, unlike in traditional antivirus and anti-spam software vendors, where scanning occurs at the desktop instead of the mail server. Scanning is more robust with deep header analysis and holistic image scanning of each piece of mail.
