As workforces grow mobile and diverse, organizations are challenged to enable secure remote access from unconventional and unmanaged devices. Today, two out of three enterprises have a traditional VPN for managed laptops. But most are waging an uphill battle to stop infected laptops from penetrating networks via VPN, and few have a comprehensive strategy for mobile handheld devices.

From accommodating mergers to expanding application breadth, many companies are finding it necessary to revamp strategies that no longer meet their needs. Simply connecting travelers to the corporate network is no longer sufficient, or even acceptable. New products and approaches have emerged to reduce risks and fill gaps, from browser-based and mobile VPNs to endpoint security and identity-based network access control (NAC).
