To stay ahead in a competitive marketplace, small businesses need to make every dollar count. That means getting the most value from your technology investments, but it also means making sure that employees have fast, reliable access to the business tools and information they need. Every minute an employee waits for an unresponsive application—and every minute your network is down—has an impact on your bottom line. When your business needs more advanced security and switch features, but value is still a top priority, you’re ready for the new generation of Cisco® Small Business managed switches: the Cisco 300 Series.
