Why Zero Trust by default matters in 2025
European organizations operate with hybrid work, SaaS adoption, multi-site footprints, and increasing regulatory pressure. Perimeter thinking and flat networks create unnecessary exposure. A Zero Trust model evaluates identity, device posture, and context for every connection, then enforces the minimum required access. The outcome is better security without added complexity and a clearer path to NIS2, GDPR, and DORA alignment.
Summary of this article
- What problem does Zero Trust solve: It removes implicit trust and lateral movement by granting least-privilege access per user and device.
- How is Zero Trust enforced: Identity-centric policies, device posture checks, microsegmented access, and per-session ZTNA.
Architectural overview at a glance
Jimber’s platform unifies control, data, identity, and telemetry planes in a cloud-managed design that MSPs can operate across multiple tenants.
| Plane | Primary components and responsibilities |
| Identity and policy | ZTNA policy engine, IdP integration, MFA, device posture, role and attribute mapping, just-in-time access |
| Enforcement and data | Network controllers virtual or physical or industrial, SWG, FWaaS, SD-WAN fabric, per-session encryption |
| Endpoint and response | EDR telemetry and isolation, posture signals, automated containment |
| Agentless and OT bridge | NIAC hardware for BYOD, IoT, and industrial systems that cannot run agents |
| Observability | Central logging, analytics, compliance reporting, API streaming for SIEM or SOAR |
| Integration | API-first automation for provisioning, policy, identity, and events across multi-tenant environments |
Principle 1. Identity-centric access replaces network-centric trust
Traditional networks grant permissions because a device sits on a subnet or connects through a VPN. Jimber flips this model. Every session is evaluated on who the user is, how they authenticated, what device they use, and whether that device complies with posture rules.
Key mechanics
- IdP federation with SSO and MFA.
- Role and attribute based policy that maps persona, group, and context to permitted applications.
- Per-application connectors so users never receive broad network access.
- Continuous posture verification to gate access and re-evaluate risk when context changes.
Outcome
Users get only the applications they need. Attackers cannot pivot simply because they landed on a network segment.
Principle 2. Microsegmentation limits blast radius by design
Microsegmentation is embedded into the access flow. Instead of granting a subnet or VLAN, the platform issues short-lived, app-level permissions enforced at the closest control point.
Segmentation scopes
- Application segmentation per FQDN or service.
- Service and protocol rules for granular controls such as HTTPS or RDP with context.
- User and device attributes limit access to compliant laptops or managed tablets.
- Time-boxed access for contractors or privileged tasks.
Why it works
If an identity is compromised, the attacker still meets walls at every lateral step. Movement across departments, sites, or OT zones is curtailed by default micro-boundaries.
Enforcement where it matters: controllers and gateways
Enforcement points are placed where they can observe and govern traffic with minimal performance impact.
Network controllers
- Virtual and physical controllers handle forwarding, identity enforcement, and encryption for branch offices, data centers, and cloud VPCs.
- Industrial controllers bring the same enforcement to production environments without redesigning the network.
Secure Web Gateway and FWaaS
Inline inspection and policy enforcement protect users from harmful destinations and keep web use compliant across locations.
SD-WAN fabric
Application-aware routing links sites with resilient performance while maintaining Zero Trust policies end to end.
EDR integration
Endpoint signals enrich policy decisions and allow rapid isolation during incidents.
NIAC for agentless devices
Network Inline Access Control appliances isolate and onboard devices that cannot run agents such as printers, sensors, or industrial machines. NIAC applies identity-aware segmentation at the port or link that touches those devices, which creates a safe bridge between IT and OT without production downtime.
How a session is authorized and enforced
- Authenticate the user through the organization’s IdP with MFA.
- Assess posture by gathering device signals such as OS version, encryption, and EDR status.
- Evaluate policy against identity and attributes for the intended application.
- Establish a short-lived session through the closest controller with per-app routing and encryption.
- Monitor continuously with inline SWG and FWaaS, streaming logs to the console and external SIEM if configured.
- Respond automatically when telemetry flags risk by revoking session tokens or isolating a device.
What sets Jimber apart from firewalls and VPNs
- Least privilege as the default rather than network presence as a permission.
- Per-app access without full tunnel overhead which improves user experience and reduces risk.
- Unified control plane that avoids brittle rule sets across many boxes.
- Agentless coverage via NIAC where traditional tools have blind spots.
- Cloud-managed operations for consistent policy and faster change management across many sites.
Governance and compliance alignment
A Zero Trust baseline simplifies evidence gathering for NIS2, GDPR, and DORA. Identity-centric controls, central logging, and least-privilege policies demonstrate governance. Short-lived sessions and posture gates support data protection expectations. The audit trail in the console and via API speeds investigations and reporting.
Performance and user experience
Per-application routing avoids hairpinning entire networks through VPN concentrators. SD-WAN keeps latency predictable between sites. Users authenticate once then receive seamless access to permitted apps while background posture checks keep sessions healthy without intrusive prompts.
FAQ
Does Jimber replace VPNs entirely?
Yes for application access. ZTNA provides per-app connectivity that renders full network tunnels unnecessary for most use cases.
How does it work with my existing firewalls?
Controllers integrate without forcing a redesign. Policies can coexist while you phase out legacy access where appropriate.
What about devices without agents?
NIAC hardware onboards and segments printers, sensors, and industrial systems so they follow the same Zero Trust rules.
Can MSPs manage multiple customers from one place?
Yes. The platform is multi-tenant with APIs for automation, consistent templates, and centralized reporting.
How does this help with NIS2?
Least-privilege access, logging, and incident response workflows help demonstrate governance and reduce exposure, which supports NIS2 compliance programs.
