Cisco's Zero Trust is a strategy
Cisco's Zero Trust is a strategy, not a single product, focusing on "never trust, always verify" across users, devices, apps, and networks, using integrated technologies like Cisco Secure Access (ZTNA), Duo (MFA/identity), Secure Internet Access (SIA), and Splunk, to grant least-privilege access, enforce policies, and continuously monitor for threats, securing hybrid work and cloud environments with visibility and analytics. Key products include the Cisco Secure Client, Duo for identity, and network segmentation tools, supported by their broad security portfolio.
"Cybersecurity is the new frontier of technology. To protect our digital lives, we must prioritize security as much as innovation."
Satya Nadella CEO of Microsoft
Cisco's Zero Trust Approach
- Core Principles: Verifies identity and context for every access request, enforces least privilege, and continuously monitors for risk
- Unified Platform: Combines disparate security tools into a cohesive platform for seamless, secure access across on-premises, cloud, and remote work environments
- Key Pillars: Identity, device trust, network segmentation (micro and macro), application security, and data protection
Key Cisco Zero Trust Products & Services
- Cisco Secure Access: Universal ZTNA solution combining Secure Internet Access (SIA) and Secure Private Access (SPA) for consistent policy enforcement
- Duo Security: Strong multi-factor authentication (MFA), device trust, and identity intelligence to verify users and devices before granting access
- Cisco Secure Client: Extends ZTNA and security policies to endpoints such as laptops and mobile devices for secure connectivity
- Splunk: Deep visibility, advanced analytics, and threat detection by integrating data across the IT environment to inform Zero Trust policies
- Network Segmentation: Macro and microsegmentation using technologies such as Cisco Cyber Vision for IoT/OT to limit lateral movement
- Cloud Security: Integration with cloud environments to ensure secure access to SaaS and IaaS applications
How It Works
- Verify Identity & Context: Authenticates users using Duo MFA and assesses device posture, including managed vs. unmanaged and compliant vs. non-compliant status
- Enforce Least Privilege: Grants access only to the specific applications or resources required, rather than full network access
- Continuous Verification: Continuously monitors user and device behavior and dynamically adjusts or revokes access if risk levels change
- Seamless User Experience: Replaces traditional VPNs for many cloud applications by providing direct, secure, and low-latency access
