Zero Trust Architecture Overview
Zero trust is built on the principle of "never trust, always verify." Every user, device, and workload must continuously prove its identity and health before accessing any resource.
Identity
30-40% of budgetStrong authentication is the foundation. This includes SSO federation, directory consolidation, phishing-resistant MFA (FIDO2/passkeys), and privileged access management. Most organizations start here.
Device
15-20% of budgetDevices must prove health before accessing resources. Endpoint detection and response (EDR), mobile device management (MDM), and device compliance policies gate access based on real-time device posture.
Network
20-30% of budgetReplace implicit network trust with microsegmentation. Software-defined perimeters, SD-WAN, and ZTNA replace VPN and flat network architectures with application-layer, identity-aware access controls.
Workload
10-15% of budgetApplications and cloud services need their own identity and communication policies. Service mesh, workload identity, API security, and cloud security posture management (CSPM) protect workload-to-workload traffic.
Data
10-15% of budgetData must be protected regardless of where it lives. Data classification, DLP (data loss prevention), encryption key management, and information rights management ensure data security across all environments.
Monitoring
10-20% of budgetContinuous visibility is essential. SIEM, UEBA, and security analytics correlate signals from all five pillars to detect anomalous behavior in real time and enable rapid incident response.
Frequently Asked Questions
How much does zero trust implementation cost?
Costs range from $200k for small organizations to $5M+ for enterprises. Per-user costs typically run $800-$2,500 all-in for the first year including implementation and licensing.
What are the five pillars of zero trust?
CISA defines five pillars: Identity, Device, Network, Workload, and Data. Each pillar has distinct technology requirements and cost profiles. See the pillars page for detailed breakdowns.
What is the most expensive part of zero trust?
Identity modernization (SSO, MFA, directory consolidation) typically accounts for 30-40% of total cost. Network microsegmentation is the second-largest cost, especially for on-premises environments.
How long does zero trust implementation take?
Full implementation takes 2-4 years in phases. Phase 1 identity and MFA takes 3-6 months. Network microsegmentation and ZTNA are typically phase 3 and can take 12-24 months.
Does zero trust replace VPN?
ZTNA replaces the broad network access model of VPN with application-specific, identity-verified access tunnels. Migration from VPN to ZTNA typically costs $80-$150 per user per year.
Is zero trust required for government contractors?
OMB M-22-09 mandates zero trust for federal agencies. Contractors handling CUI are increasingly expected to demonstrate zero trust-aligned controls through CMMC and FedRAMP requirements.
