A regional law firm with 75 employees is transitioning to a permanent hybrid work model. The firm handles highly sensitive client data and must comply with strict data privacy regulations. Their current infrastructure consists of basic on-premises servers and a traditional firewall. The managing partners have two main goals: 1) ensure seamless and secure collaboration for employees both in the office and at home, and 2) gain visibility into potential security threats without hiring a dedicated security team. A Cisco partner engineer proposes a solution that combines Webex for collaboration and Cisco Umbrella for DNS-layer security. To demonstrate the value, the engineer needs to show how these solutions address the firm's specific compliance and security concerns. Which approach represents the most effective cross-selling strategy in this scenario?
