ZTNA with Phoenix: rethinking security in a zero trust world

With increasing cyber threats, hybrid workforces, and borderless IT, Zero Trust Network Access (ZTNA) is the future of secure access.

So, what is zero trust?

Zero Trust Network Access (ZTNA) is a cyber security framework designed to secure modern digital environments by eliminating implicit trust and enforcing continuous verification. Unlike traditional VPNs or perimeter-based models, ZTNA assumes no user or device is trusted by default, regardless of location.

Based on the principle of “never trust, always verify,” ZTNA ensures every access request is authenticated, authorised, and encrypted – whether it comes from inside or outside your network.

So, why ZTNA and why now?

Traditional perimeter-based models are no longer enough

Remote work, cloud sprawl, and advanced threats demand a new security paradigm

ZTNA empowers you to secure access across all users, devices, and data – wherever they reside

Real-world examples of ZTNA in action

Private Sector

A mid-sized manufacturing company adopted ZTNA to support secure access to ERP and supply chain systems across multiple continents. By using cloud-based ZTNA, they improved performance and reduced operational costs tied to legacy VPNs.

Healthcare

A UK NHS Trust implemented ZTNA to secure access to clinical applications by external specialists. By replacing their VPN with a ZTNA solution, they reduced access delays by 70% and eliminated lateral movement within the network.

Government

A local authority deployed ZTNA to support secure remote working. They now use device posture checks and identity verification to determine access – ensuring sensitive citizen data stays protected.

The six foundations of Zero Trust explained

Explore how ZTNA integrates into every layer of your cyber security stack:

ZTNA reduces lateral movement across your network, enabling application-level segmentation and secure remote access.

Zscaler is a leader in cloud-native network security. Their ZTNA offering, Zscaler Private Access (ZPA), allows organisations to connect users directly to apps – not the network – eliminating lateral movement.

Zscaler benefits:

Secure access to internal applications without VPNs
Least-privilege access based on identity and context
Integrated posture checks and user risk scoring

Identity is the new perimeter. ZTNA ensures access is tied to strong identity controls and context-aware policies.

One Identity brings enterprise-grade Identity Governance and Administration (IGA) to your Zero Trust strategy. Their tools ensure access is role-based, time-bound, and verifiable – a key pillar of ZTNA.

One Identity benefits:

Enforce least privilege access via RBAC

Integrate MFA and session monitoring
Ensure compliance through automated identity lifecycle management

Your endpoints are where threats strike first. ZTNA only grants access to verified, healthy devices.

SentinelOne brings AI-powered endpoint protection that integrates directly into a ZTNA framework. It ensures access is only granted to healthy, trusted endpoints – whether BYOD or corporate-managed.

SentinelOne benefits:

Device posture enforcement before access is granted

Autonomous threat detection and response (EDR/XDR)

Visibility across all devices and endpoints

ZTNA secures sensitive data wherever it lives, from cloud to on-premises.

Rubrik protects your critical data from ransomware, insider threats, and accidental deletion. As part of a ZTNA strategy, Rubrik ensures that even if access is granted, your data remains secure and recoverable.

Rubrik benefits:

Immutable backups with air-gapped architecture

Ransomware detection and instant recovery

Compliance and data governance reporting

ZTNA is not just a security architecture—it’s a business enabler. Embedding strong GRC into your cyber security strategy aligns your policies with NCSC guidance, GDPR, and ISO standards.

Phoenix delivers strategic GRC consultancy that helps embed ZTNA into your wider security and compliance frameworks. We align Zero Trust implementations to NCSC guidance, ISO standards, and sector-specific requirements.

Phoenix GRC benefits:

Map Zero Trust maturity across your organisation

Identify risks and create actionable security roadmaps

Support board-level buy-in through audit and policy planning

Accelerate your Zero Trust journey through scalable cloud marketplaces. With 84% of organisations are prioritising Zero Trust in their cloud strategies.

Phoenix enables seamless ZTNA adoption through the Azure and AWS Marketplaces, reducing friction and speeding up deployment.
