Compromised security

• Hardware / software acquisition cost

• Deployment cost (centrally and in remote offices)

• Employee training cost

• Ongoing integration and maintenance cost

• More time from vulnerability discovery to patch

• More difficult to maintain unified policies • Lower visibility, less accurate auditing
