ZTNA — Secure Access Where Traditional Models Fall Short
Home office, mobile devices, cloud services, and flexible team structures: All of this has long been part of everyday business life.
Remote work, mobile devices, cloud services, and flexible team structures are now fundamental to today’s enterprises. Access to systems and data happens across locations and devices, often simultaneously by multiple user groups. To support this reality, IT landscapes have grown increasingly fragmented and dynamic. Traditional security models built around a fixed network perimeter buckle under this complexity—putting enterprise security at risk.
Zero Trust Network Access (ZTNA) offers a modern remedy. Instead of granting blanket trust, ZTNA operates on the principle: “Trust no one, verify everything.” Access rights are no longer assigned once and forgotten; they depend on factors like user role, device posture, and location.
In an era of mounting threats and stricter regulations, this context-driven, identity-centric approach provides a flexible yet robust access model. Organizations that want their IT architecture to stand the test of time simply can’t ignore Zero Trust.
Rethinking Access Control — Risks When ZTNA Is Absent
Access controls have moved beyond mere technical configuration. They determine who can reach what, which data is visible, and where blind spots emerge. Yet many organizations still rely on outdated models. Permissions are granted once, seldom reviewed, and often too generous. Once a user is inside, they frequently inherit more privileges than necessary—regardless of context or device health.
When multiple teams, external vendors, or mobile endpoints come into play, dangerous opacity sets in. Real-world consequences manifest in scenarios such as:
- Overbroad vendor access: An external contractor receives credentials to a central management tool. Because permissions weren’t scoped narrowly, they can also see sensitive internal directories—introducing a major data-leak risk.
- VPN compromise pivoting inside: An attacker exploits a VPN credential, gaining entry to the corporate network. Without network segmentation, they traverse east–west until they reach high-value systems.
- Unsecured personal device infection: An employee uses an unmanaged laptop or smartphone to connect. One malicious file or a spoofed email can introduce malware that rapidly spreads throughout the network.
These scenarios create latent insecurity that often goes unnoticed—until it’s too late. Confidential data falls out of control, compliance obligations go unmet, and audit trails prove inadequate. All because there isn’t necessarily a visible vulnerability—just overly permissive access.
Unrestricted privileges open side doors into your organization, and cybercriminals know exactly where to look.

ZTNA with concentrade — Custom Design, Secure Deployment
Adopting ZTNA requires far more than flipping a switch on new technology. To ensure access rights are secure, auditable, and fit for purpose, you need a thoughtful, bespoke framework.
That’s why concentrade starts at the foundation:
Analysis of Existing Access Patterns & Pain Points
We kick off with a deep-dive inventory alongside your IT team: mapping current access pathways, uncovering shadow IT, and identifying risk hotspots. Who can access what, through which channels, with which privileges—and why?
Crafting a ZTNA Target State (Roles, Contexts, Controls)
Based on our findings, we define an organizationally tailored ZTNA blueprint. This establishes who should reach which resources, under what contextual conditions (device posture, location, time of day), and which enforcement checks—such as step-up authentication or microsegmentation—are required.
Selecting & Integrating Suitable Technologies
We remain vendor-agnostic: choosing components that fit your existing infrastructure and business needs. Seamless interoperability is paramount. During technical implementation, we ensure a smooth handoff to your operations team so day-to-day business isn’t disrupted.
Deployment, Handoff, and Ongoing Operations
ZTNA isn’t a one-off project; it’s an evolving discipline. Access policies need constant tuning, and new requirements emerge as your environment changes. Through a flexible service model, we accompany you every step: updating policies, refining controls, and rolling out adjustments as new applications, users, or risks appear.
More than technical skill, we bring strategic vision and hands-on expertise. We develop security architectures that truly fit your organization—never locked into a one-size-fits-all approach.
Working closely with your internal IT, we tackle questions and challenges together. Whether you need a full-scale rollout with long-term management or a focused solution for a critical use case, what matters to us is minimizing complexity and maximizing impact.
Your Path to ZTNA with concentrade:
Consultation
We clarify your goals, challenges, and constraints.
Analysis
We jointly inventory existing access paths, risks, and organizational nuances.
Design
Based on the assessment, we develop a tailored ZTNA blueprint—defining roles, contexts, and technology choices.
Integration & Operations
We implement in a vendor-neutral, practical way. Optionally, we continue to support you in evolving and operating the solution.
ZTNA in Practice — What Organizations Gain
ZTNA isn’t just an abstract security “upgrade”; its benefits become tangible in everyday workflows. Access to systems and data is governed by fine-grained rules—based on roles, contextual attributes (device health, location, user risk score), and explicit approvals. This dramatically reduces the attack surface while increasing visibility and control over permissions.
Organizations gain:
- Audit-Ready Controls:
Every access event is logged with context. During audits or internal reviews, you can demonstrate exactly who accessed what, when, from where, and why—easing compliance with GDPR, BSI, or industry-specific mandates. - Minimized Risk & Regulatory Compliance:
Documented, context-aware access policies make it simpler to meet data-privacy and security frameworks—turning regulatory hurdles into managed processes rather than ad hoc fire drills. - Improved User Experience & Productivity:
Authorization decisions happen in real time, avoiding lengthy approval cycles. Users access resources swiftly—no more unnecessary ticket queues—boosting satisfaction and throughput. - IT Team Efficiency:
Clear ownership and automated enforcement reduce manual intervention. Administrators spend less time juggling permissions and more time on strategic initiatives—such as cloud migrations or network modernizations. - Heightened Security Awareness:
A culture of minimal trust and continuous verification fosters awareness around the value of cybersecurity. When users know their access is tightly controlled, they become active partners in maintaining a secure environment.
