Security that scales with your network

Distributed enterprises running separate firewalls, policies and management consoles at each site do not have one coherent security model. They have accumulated risk across locations. evoila consolidates that complexity into one centrally managed Fortinet Security Fabric. The result is a security posture that IT teams can prove, audit and scale without adding management overhead. NIS2 and ISO 27001 requirements are addressed from the first stage of the architecture and deployment.

  • 60% fewer management touchpoints: one console replaces per-site firewall UIs and disconnected policy sets
  • Sub-second threat response: FortiGuard AI-driven intelligence blocks threats before lateral movement begins
  • Audit-ready from deployment: automated compliance reports for NIS2, ISO 27001, and BSI IT baseline protection

Distributed networks create distributed risk

Multi-site enterprises typically reach a point where network security has grown faster than it was designed. Branch offices run local firewalls configured independently. VPN policies differ by site or user. Monitoring is split across tools that don’t share context. When a security incident occurs, the average IT team spends 4–6 hours identifying the affected perimeter, not because the threat was sophisticated, but because the infrastructure has no unified view or management.

The operational burden compounds daily: every firewall rule change requires coordination across locations, every new site means a new management silo, and every compliance audit exposes the gaps between intended policy and actual configuration. IT leads and admins are firefighting instead of operating strategically.

NIS 2.0 tightens reporting obligations and mandates documented security controls across all network segments.  Organisations without a consolidated security architecture will fail audits, face penalties, and remain exposed to threats that a unified platform would detect and block automatically. Waiting is no longer a neutral choice.

The average IT team spends four to six hours identifying the affected perimeter after an incident

Not because the threat was sophisticated, but because the infrastructure has no unified view.

The Challenge

Security you cannot see from one place cannot be managed from one place

No unified visibility

Monitoring split across per-site tools means no correlation between events. When lateral movement begins, there is no single view to detect it.

High costs without benefit

Every firewall rule change requires manual coordination across locations. Every new site adds a management silo. Every compliance audit exposes the gap between intended policy and actual configuration.

Compliance without evidence

NIS2 and ISO 27001 require documented controls across all network segments. Distributed logging and manual record-keeping cannot produce the audit evidence regulators now require.

The good news: Moving to one Security Fabric does not mean rebuilding the whole environment from scratch.

evoila migrates existing environments to Fortinet with zero production downtime and a defined migration path that analysis your current rules before a single change reaches production.

Our Solution

Fortinet Security Fabric: One platform, every site

Fortinet Security Fabric connects every location, cloud connection and remote user through one management layer. evoila designs the architecture for your topology, migrates the existing rule base and can operate the environment afterwards as a managed service if needed. The goal is not just centralisation. The goal is consistent control that holds up in daily operations.

Centralised policy management

FortiManager enforces one rule set across your entire estate. Version-controlled changes and mandatory approval workflows mean no configuration drift, no site exceptions, and full audit traceability.

Unified visibility and compliance reporting

FortiAnalyzer aggregates logs, events, and threat intelligence from every device into a single data lake. Real-time dashboards and automated compliance reports replace weeks of manual audit preparation.

One operating system across functions

FortiOS brings NGFW, IPS, SSL inspection, application control and zero trust access into one platform. No separate management planes. No policy gap between different tools.

Built for the environment you actually run

evoila does not roll out a generic default design. We build the deployment around your site topology, network zones and compliance requirements, with validated patterns for multi-tenant and multi-location enterprise environments.

Tech-Deep-Dive

Inside the Fortinet Security Fabric

FortiManager keeps policy consistent

FortiManager acts as the single source of truth for firewall policy across the estate. Changes move through a workflow that enforces review before production deployment. Policy revisions are timestamped, attributable and reversible. When an audit asks for historical configuration evidence, the system can provide it directly. ADOM separation also supports multi-tenant management across separate business units or regulatory scopes.

FortiAnalyzer and evoila MDR: Visibility that enables action

FortiAnalyzer summarises logs from every FortiGate, FortiSwitch, FortiAP and FortiClient in the fabric at scale. Correlation rules surface attack patterns across sites that no per-device view would detect. evoila MDR extends this with third-party log sources such as Active Directory, cloud platforms and endpoint protection. Where MDR is in scope, confirmed threats can be escalated into response workflows with containment actions typically initiated in under 30 minutes.

Zero Trust Network Access: Replacing implicit trust

FortiGate-native ZTNA replaces implicit network access with identity-verified, application-specific sessions. Users and devices are authenticated on every connection attempt, regardless of location. Access is granted to named applications, not network segments. Device posture is checked continuously: an endpoint that falls out of compliance loses access automatically without requiring a manual policy update. This eliminates the lateral movement risk that VPN-based access creates, where a compromised remote session gains access to the entire network segment rather than a single application.

Technical Advantages

What changes for you on day one of production

60% fewer management consoles

One FortiManager console replaces per-site firewall UIs and disconnected policy sets across your entire estate. Less tooling, less coordination, less room for error.

Automated threat response

evoila MDR closes the loop between detection and action. When a threat is identified, endpoints are quarantined and IPs blocked in under 30 minutes, without waiting for manual review.

100% policy consistency across all sites

Policies defined once in FortiManager propagate to every FortiGate within seconds. Every location, every workload, every user, covered by the same rule set from day one.

Audit reports in one day

FortiAnalyzer generates NIS2, ISO 27001, and BSI IT-Grundschutz compliance reports automatically. What previously took weeks of manual preparation takes one day.

FAQs

Commonly asked Questions about Network Security

A greenfield deployment for 5–15 sites runs 8–14 weeks from kick-off to production sign-off, including architecture design, FortiManager setup, and site-by-site FortiGate commissioning. Brownfield migrations where existing firewall rules must be analysed, cleaned, and ported add 3–5 weeks for the rule assessment phase. Zero-touch provisioning via FortiManager reduces the physical on-site time per branch to under two hours.

That depends on the number of sites, the existing tooling landscape and the managed-service scope. evoila includes a TCO view during scoping so the commercial case is based on operational effort, tooling reduction and risk reduction, not only on licence costs.

Yes. evoila’s migration methodology runs the new FortiGate in parallel with the existing firewall during a validation period. Traffic is shifted application-by-application and site-by-site, with rollback capability at each step. No site goes dark during the cutover. Existing firewall rules are analysed for conflicts and redundancies before migration. We do not port broken policy to a new platform.

evoila offers three post-deployment tiers: standard support with guaranteed response SLAs, co-managed operations where evoila handles specific tasks such as policy changes and FortiGuard updates, and full managed security operations with 24/7 NOC coverage, proactive threat hunting, and monthly security posture reporting. All tiers include access to evoila’s certified Fortinet engineers not a shared offshore helpdesk.

FortiAnalyzer generates automated compliance reports mapped to NIS 2.0 controls and ISO 27001 out of the box. FortiManager’s change audit log satisfies documentation requirements for access control and configuration management. evoila’s deployment methodology includes a compliance gap assessment at project start and a post-deployment evidence package covering network segmentation, logging, incident response capability, and supply chain security controls ready for submission to auditors or regulators.
