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.

Cisco Duo

Cisco Duo helps you secure your workforce by verifying the identity of every user and the health of every device before they access your applications. You can implement strong multi-factor authentication (MFA) that is easy for your team to use, reducing the risk of data breaches caused by compromised passwords. The platform gives you a clear view of every device connecting to your network, whether it is company-issued or a personal mobile phone.

You can also simplify your team's workday with single sign-on (SSO), allowing them to access all their cloud and on-premise apps with one secure login. It scales effortlessly from small startups to global enterprises, offering a 30-day free trial to get you started. By enforcing risk-based access policies, you ensure that only the right people and healthy devices can reach your sensitive data.
