This combination approach has particular resonance when considering security. Running solutions that are designed to protect an organization from viruses, spyware or malware in the cloud offers significant benefits, typically preventing around 80 percent of e-mail-born attacks from ever reaching the organization.
This not only improves the quality of security and reduces risk, but has a knock-on effect on infrastructure costs, minimizing the overhead on the network and improving user productivity. Furthermore, for organizations with strict compliance requirements that demand every e-mail message-whether genuine or spam-is stored for anything up to 30 years, preventing 80 percent of these e-mail messages from accessing the corporate network significantly reduces the storage overhead.
However, organizations cannot just rely on the cloud-based solution. There is also a need to address the 20 percent of e-mail messages that do come through to the organization. Running a local solution in tandem with the cloud-based technology enables users to locally manage their own whitelists, greylists and blacklists to fine-tune spam management and improve overall security and productivity levels.
