What Zentera Systems does
Zentera Systems, Inc. is a privately held Zero Trust security company founded in 2012 and headquartered in Milpitas, California. The company develops the CoIP (Cyber over IP) Platform, a software-defined overlay security architecture that delivers Zero Trust Network Access (ZTNA), microsegmentation via Virtual Chambers, and secure remote access without requiring network redesign, infrastructure changes, or agent installation on protected assets. The platform comprises the zCenter Orchestrator (central policy engine), zLink software agents, CoIP Gateway Proxy appliances (with patent-pending Teraflow throughput technology supporting up to 6Gbps per flow), and Zero Trust Gatekeeper hardware appliances for OT/ICS environments. In 2026, Zentera launched Ensage AI, a new product module providing architectural containment for enterprise AI agent deployments.
Zentera serves large enterprises in semiconductor, electronics manufacturing, OT/critical infrastructure, government, healthcare, and financial sectors, with named customers including Cadence Design Systems, Siemens, Delta Electronics, Qualcomm, Ambarella, and Cybriant. The company's go-to-market combines direct enterprise field sales (with solution architects conducting architecture reviews, proof-of-concept pilots, and 30-day rollout plans) with a formal Channel Partner and Technology Partner program. Revenue is generated through software platform subscriptions (sold per-asset or enterprise-wide) and hardware appliance sales for the Zero Trust Gatekeeper product line.
The company has raised approximately $15.4 million in disclosed funding across four rounds between 2015 and 2018, with CDIB Ventures as the only identified institutional investor (lead investor in the 2015 Series 2). Operating geographies span the USA, Taiwan, India, Germany, and China. The leadership team is led by founder, president, and CEO Jaushin Lee, with VP Engineering Will Chu and VP of Marketing & Product Mike Ichiriu.

Revenue model
- Software Platform Subscription: The CoIP Platform is sold as a software subscription covering the zCenter Orchestrator, zLink agents, Gatekeepers, and Gateway Proxies. The subscription model includes entitlement to platform management, agent deployment, policy enforcement, and support/maintenance, typically sold on a per-asset or enterprise-wide basis.
- Hardware Appliances (Zero Trust Gatekeeper): ZTG physical appliances (1U and 2U form factors, industrial DIN-rail units) are sold as hardware products alongside or independent of the software subscription, providing inline Zero Trust enforcement for OT/IoT environments.

Zentera Systems product offering
Product offeringCore offering
Zentera Systems sells the CoIP (Cyber over IP) Platform, a software-defined Zero Trust overlay security solution delivering microsegmentation via Virtual Chambers, Zero Trust Network Access (ZTNA), and secure remote access for hybrid, multi-cloud, and OT/ICS environments. The platform deploys alongside existing infrastructure without requiring network redesign, IP changes, or agent installation on protected assets, and is sold via subscription alongside hardware appliances (Zero Trust Gatekeeper) for legacy and industrial environments.
Product overview
Zentera Systems offers the CoIP Platform as its core unified product, which delivers Zero Trust security through an overlay architecture that doesn't require network redesign. The platform comprises three main enforcement models: zLink agents (software-based, host-level enforcement for servers and VMs), Zero Trust Gatekeeper appliances (hardware-based inline enforcement for OT/legacy systems), and Gateway Proxy (network-level ZTNA termination). Supporting these are Virtual Chambers (software-defined security boundaries for microsegmentation), Ensage AI (AI agent security containment), and Secure Remote Access. The zCenter Orchestrator serves as the central policy engine, while the overlay transport enables consistent security across cloud, on-premises, and hybrid environments.

Products and services
- CoIP Platform Central Zero Trust security platform providing overlay-based microsegmentation and ZTNA. Includes the zCenter Orchestrator for centralized policy management, zLink agents for endpoint security, and supports hybrid/multi-cloud environments without requiring network changes. Sold to enterprise security teams.
- zLink (CoIP Endpoint Proxy) Lightweight software agent (~50MB, no reboot required) that provides microsegmentation, application cloaking, and overlay ZTNA for application servers and endpoints. Supports Windows (XP and up), Linux (kernel 2.6.32+), and MacOS.
- Zero Trust Gatekeeper (ZTG) Hardware appliances providing inline agentless microsegmentation and ZTNA for workloads that cannot run software agents. Available in 1U, 2U, and industrial DIN-rail form factors with optional hardware bypass.
- CoIP Gateway Proxy Virtual or physical appliance providing ZTNA service termination for remote users and applications. Uses patent-pending Teraflow technology enabling up to 6Gbps throughput per flow.
- Virtual Chambers Software-defined security boundaries (cybershields) that wrap around applications or assets to enforce microsegmentation. Blocks lateral movement, prevents data exfiltration and C2 callbacks, and works across on-prem, cloud, and OT environments.
- Ensage AI AI security module for enterprise AI agent deployments. Provides enclave-based reachability enforcement, credential substitution at endpoints, and process-level agent detection with session attribution to contain rogue AI agents.
- Secure Remote Access (ZSA) Zero Trust remote access solution for work-from-home and distributed workforce scenarios. Provides MFA-authenticated access to corporate resources without VPN, supporting RDP, VNC, SSH, and TCP/IP applications.

Zentera Systems competitors and assessment
Company assessmentDirect peers
- Illumio: Pure-play microsegmentation vendor whose segmentation value proposition directly overlaps Zentera's Virtual Chambers. Both target ransomware containment and east-west traffic control in hybrid data centers and cloud environments.
- Claroty: OT/ICS cybersecurity vendor specializing in critical infrastructure protection. Highly comparable to Zentera's Zero Trust Gatekeeper for OT environments, though Claroty focuses on asset visibility and vulnerability management where Zentera emphasizes inline enforcement.
- ColorTokens: Microsegmentation and Zero Trust platform focused on asset-based segmentation across data center, cloud, and endpoints. Highly comparable to Zentera's Virtual Chambers overlay microsegmentation model.
- Appgate (now Gen Digital / BeyondTrust CyberArk adjacent): Zero Trust Network Access vendor built on Software-Defined Perimeter architecture, very close functional overlap with Zentera's CoIP overlay ZTNA approach. Targets similar enterprise and government buyers.
Broad incumbents
- Cloudflare (Cloudflare One / Access): Cloudflare One delivers Zero Trust Network Access, SWG, CASB, and DLP via a global edge network. Directly comparable to Zentera's overlay ZTNA proposition and a frequent competitor in mid-market and enterprise deals.
- Cisco (Duo + Secure Access): Duo provides identity-centric Zero Trust access, and Cisco's broader security portfolio competes directly with Zentera's universal ZTNA. Comparable customer base in enterprise and OT-adjacent environments.
- Palo Alto Networks (Prisma Access): Prisma Access delivers ZTNA and microsegmentation as part of a converged SASE/security platform. Competes with Zentera's overlay ZTNA and Virtual Chambers microsegmentation while bundling CASB, SWG, and firewall-as-a-service.
- Akamai (Guardicore + Enterprise Threat Protector): Akamai acquired Guardicore for microsegmentation and offers Zero Trust access through its broader application and security platform. Directly competes in microsegmentation and ZTNA, particularly for hybrid enterprise deployments.
- Zscaler: Cloud-delivered security platform offering ZTNA (Zscaler Private Access) alongside broader SASE capabilities. Closest direct functional competitor to Zentera's Universal ZTNA and overlay access story, but operates at vastly larger scale and broader portfolio.
Emerging players
- Tailscale: WireGuard-based overlay networking platform increasingly positioned as Zero Trust access for developers and mid-market. Overlaps with Zentera's overlay ZTNA philosophy but lacks Zentera's enterprise OT, microsegmentation chambers, and AI agent security.
