About Portnox Security

Portnox is a cloud-native enterprise access control provider that helps organizations secure every identity - human and non-human - across networks, applications, and infrastructure. As identities, devices, and workloads multiply across modern environments, Portnox enables continuous access verification based on identity context, device posture, and risk signals. Its unified platform brings together passwordless authentication, access control, continuous policy enforcement, and automated response through a single policy engine.

Portnox gives security and IT teams real-time visibility into everything connecting and the ability to quickly restrict, quarantine, or revoke non-compliant access. Today, Portnox actively manages more than one million devices worldwide, secures 40 million authentication sessions, and blocks over one million unauthorized access attempts every day.

CAPABILITIES:

• Discover and assess users, devices, and identities connecting to corporate resources

• Unify continuous zero trust access control on networks, applications, and infrastructure

• Enforce identity- and context-aware access policies

• Enable secure remote work without complexity 

• Deliver passwordless authentication, device posture checks, and continuous access enforcement

• Control administrative access to routers, switches, firewalls, and other network devices

• Improve audit readiness with visibility, access logs, and policy-based compliance controls

BUILT FOR:

Portnox is designed for distributed organizations that need to manage access across employees, contractors, service accounts, managed devices, unmanaged devices, IoT, network infrastructure, SaaS applications, private applications, and AI agents. The platform helps reduce reliance on on-premises appliances, legacy VPNs, and fragmented access tools by centralizing access policy enforcement from a single cloud-native policy engine.

INTEGRATIONS:

Portnox integrates with the tools you already use (including Azure AD / Entra ID, Okta) and works with your existing network appliances, (such as Meraki, Fortinet, and more), and many other identity and network infrastructure tools.

Zero Networks delivers identity-based microsegmentation that contains AI-speed attacks before they disrupt the business. The solution delivers immediate visibility, verifies every connection, and automatically blocks lateral movement to protect uptime, revenue, and operations – even when attackers get inside.

Zero Networks automatically contains attacks, closing internal pathways by default and opening them only when needed. A deterministic, human-on-the-loop automation engine continuously maps internal communication paths to build precise least-privilege policies that adapt as the network changes, then enforces them by orchestrating native firewalls.

What are the key features of Zero Networks?

·Identity-Based Microsegmentation: Divides the network into granular segments where internal pathways are closed and invisible by default, and access is governed by identity-based controls that follow users, devices, AI agents, and applications.

·Automated, Deterministic Policy Creation & Enforcement: Learns real logon activities, account behaviors, and asset access patterns to build granular policies based on legitimate behavior that a human can review and simulate before enforcement.

·Dynamic Access Control: Continuously monitors internal communication paths and automatically flags privileged access, anomalous paths, or high-risk ports to adapt policies as the network changes.

·Layer 3 MFA: Secures privileged internal pathways by closing admin ports, sensitive systems, and critical services by default, opening them only temporarily for pre-approved identities after just-in-time verification.

·Comprehensive Coverage and Scalability: Protects IT, OT, and IoT assets across all environment types – on-premises, cloud, hybrid, and Kubernetes.

What benefits should users look for in reviews when evaluating Zero Networks?

·AI-Speed Attack Containment: Stops ransomware, zero-days, and compromised AI agents before they can move laterally.

·Business Continuity: Proactively shrinks blast radius to protect uptime and operations, even when attackers get inside.

·Fast Time to Value: Activates protection in minutes and segments 90%+ of the average customer network within 90 days.

·Operational Efficiency: Deterministic automation replaces manual tagging, rule building, and tuning, so security scales with the business instead of headcount.

·Streamlined Compliance: Least-privilege access, granular network segmentation, and always-current network visibility support mandates like HIPAA, NIS2, and more.

Zero Networks protects global enterprises across financial services, manufacturing, healthcare, aviation, and more – its automated, adaptive approach is particularly beneficial in complex environments with rigorous uptime standards and compliance requirements.

Pricing for Zero Networks typically involves a subscription model based on the number of users and devices. The company offers robust customer support, including deployment assistance, training, and ongoing technical support to ensure optimal performance and security.

In summary, Zero Networks strengthens cyber resilience with automated, identity-based microsegmentation, containing AI-speed attacks to protect critical operations and preserve uptime while eliminating complexity.
