Cisco ISE

Cisco Identity Services Engine (ISE) gives you a centralized way to manage security across your entire network. You can see exactly who and what is connecting to your environment, whether they are using a wired, wireless, or VPN connection. By gathering real-time data from users and devices, you can make informed decisions about who gets access to specific resources and under what conditions.

You can automate your network security by creating granular policies that adapt based on the user's role, device type, and location. This helps you stop threats before they spread by automatically isolating suspicious devices. Whether you are managing a corporate office or a distributed workforce, it provides the visibility you need to maintain a zero-trust security posture without slowing down your team.

Zscaler Internet Access

Zscaler Internet Access (ZIA) transforms how you secure your workforce by moving your security stack to the cloud. Instead of routing traffic through a slow corporate VPN or physical appliances, you connect users directly to the world’s largest security cloud. This ensures your team stays protected from malware, ransomware, and phishing attempts whether they are working from the office, a home network, or a coffee shop.

You can replace outdated web gateways with a unified platform that inspects all traffic, including encrypted data, without slowing down your connection. It simplifies your infrastructure by eliminating the need to manage hardware, while giving you full visibility into every user activity and potential threat across your entire organization. By using a zero-trust architecture, you ensure that security follows the user, not the network.
