Best Zero Trust Network Access (ZTNA) Tools

Action-Centric Cloud Security

We make life better for billions of people, trillions of times a day

Axis Security provides HPE Aruba Networking SSE, a cloud-native security platform integrating Zero Trust Network Access (ZTNA), Secure Web Gateway (SWG), and Cloud Access Security Broker (CASB) with SD-WAN for unified SASE. Acquired by HPE Aruba, it delivers consistent Zero Trust policies across remote users, branches, and data centers via local edge virtual machines that broker traffic to private apps without cloud backhaul. Best for enterprises seeking SSE as a SASE stepping stone, with features like SSL inspection, sandboxing, and AI-driven reputation blocking for malware and risky sites.

Protect devices, apps, networks and data with isolation-based security solutions.

NordLayer is a cloud-native SASE platform consolidating SD-WAN, firewall-as-a-service (FWaaS), secure web gateway (SWG), cloud access security broker (CASB), and zero trust network access (ZTNA) into a unified service. The vendor targets enterprises transitioning from point-solution security architectures to integrated cloud-delivered frameworks. NordLayer serves organizations requiring secure remote access, hybrid IT environments, and zero trust implementation without hardware-dependent infrastructure.

Nord Security offers a suite of business tools including NordLayer for network access and NordPass for credential management, focused on the SMB and mid-market segments. It provides a secure service edge (SSE) approach to remote access, replacing legacy VPNs with a Zero Trust Network Access (ZTNA) model. The platform integrates identity-centric access control with password security and threat exposure monitoring.

OpenText Core EDR provides endpoint detection and response integrated with SIEM, SOAR, and vulnerability assessment in a single cloud platform. It deploys a lightweight agent for telemetry collection on endpoints including laptops, servers, and mobile devices, capturing process execution, file changes, network connections, and registry modifications. Built for MSPs managing SMB clients, it uses pre-configured policies, automated playbooks for containment like device isolation and process termination, and CVE-based vulnerability scanning. Global threat intelligence and syslog/API integrations with IT, security, and PSA systems enable multi-client visibility and response without additional vendors.

Perimeter 81, acquired by Check Point in 2023 and rebranded as Harmony SASE, delivers a cloud-native Secure Access Service Edge (SASE) platform consolidating networking, Zero Trust Network Access (ZTNA), secure web gateway (SWG), and cloud access security broker (CASB) for remote and hybrid workforces. It replaces legacy VPNs with software-defined perimeters, IPSEC tunnels, and WireGuard connectors to private applications, enforcing granular policies based on identity, device posture, geo-location, and time. Best suited for mid-sized enterprises migrating to cloud environments seeking unified SSE without hardware deployments.

Smallstep provides a Device Identity Platform that enables high-assurance Zero Trust security through automated, short-lived PKI certificates and device-bound authentication. It streamlines authentication workflows to eliminate phishing risks and password dependency by ensuring only managed, healthy devices can access sensitive resources. The solution replaces legacy static credential systems and complements existing SSO providers with granular device-level visibility.

Twingate provides Zero Trust Network Access (ZTNA) using software-defined perimeters to hide resources from public and private networks, enabling direct encrypted tunnels between authenticated users and resources. It acts as a cloud-native control layer for Zero Trust orchestration, integrating with identity providers, MDM, and EDR tools. Positioned as a lightweight SASE alternative to VPNs, it supports phased deployments without infrastructure changes. Best for organizations seeking rapid ZTNA adoption for remote access to critical resources while maintaining existing networks.
