Fortinet Firewalls

Secure networking, engineered properly. Performance, control, and confidence.
Chat About Fortinet

Fortinet firewalls are powerful platforms. FortiGate combines next-generation firewall capability, SD-WAN, threat intelligence, and deep inspection into a single operating system. On paper, it is extremely capable.

In practice, the outcome depends entirely on how it is deployed, configured, and managed over time.

We have seen well-intentioned deployments drift into policy sprawl, inconsistent segmentation, underused security features, or performance bottlenecks caused by rushed architecture decisions. The technology was sound. The implementation was not.

We work with organisations to ensure Fortinet firewalls strengthen operations rather than complicate them. Architecture reflects real traffic flows. Policies are clear and auditable. Features are enabled where they add value, not simply because they exist.

What a Well-Designed Fortinet Deployment Enables

When implemented properly, FortiGate delivers more than perimeter protection.

Predictable performance

Throughput, inspection, and SSL decryption are aligned to real-world traffic patterns so protection does not introduce latency or instability.

Clear segmentation

Trust boundaries are defined deliberately, reducing lateral movement risk and simplifying audit conversations.

Operational visibility

Security teams understand what is happening across the estate without drowning in logs or disconnected alerts.

Policy consistency

Rules are rationalised, documented, and maintainable, reducing drift as environments evolve.

Integrated security

Firewalls, switching, wireless, and remote access operate as a coherent platform rather than isolated components.

Why Positiv Technology

Deep FortiGate Experience, Across the Stack

Our team brings over 25 years of hands-on FortiGate experience across enterprise, mid-market, and regulated environments.

We design architectures around real traffic flows and business-critical applications, not generic templates. High availability, clustering, and failover behaviour are planned and validated to ensure resilience under load or failure conditions.

We enable next-generation features deliberately. Inspection, IPS, application control, threat prevention, and secure access are configured in a way that strengthens protection without introducing unnecessary overhead. SSL inspection is assessed carefully, balancing visibility with performance and privacy considerations.

SD-WAN design is aligned to connectivity strategy, ensuring routing, failover, and traffic prioritisation reflect operational priorities. Remote access and identity integration are structured cleanly, reducing reliance on overly permissive policies.

Just as importantly, we focus on maintainability. Rule sets are rationalised. Object groups are structured logically. Firmware strategy and lifecycle planning are considered from day one, reducing the risk of instability during upgrades.

Secure Networking, Not Just a Firewall

Fortinet’s Secure Networking architecture brings together FortiGate, FortiSwitch, and FortiAP under FortiOS and FortiLink to deliver consistent policy and centralised management across the LAN edge.

When designed correctly, this unified model simplifies segmentation, improves visibility, and reduces duplication of effort between wired and wireless access layers.

Fortinet’s continued recognition in the Gartner Magic Quadrant for Enterprise Wired and Wireless LAN Infrastructure reflects the maturity of this platform. But recognition alone does not guarantee results. Architecture discipline does.

We help organisations decide where unified Fortinet architecture makes operational sense; and where a mixed-vendor approach may be more appropriate.

Our Approach

Fortinet Expertise, Applied to Your Environment

We do not treat Fortinet as a product to resell. We treat it as a platform that must align with how your organisation operates.

That means:

  • Designing around business-critical applications and growth plans
  • Sizing appliances appropriately rather than overspecifying
  • Validating configuration before go-live
  • Reducing unnecessary complexity
  • Ensuring security strengthens performance rather than constraining it

Our role is to ensure you extract lasting value from FortiGate, not just achieve a working configuration on day one.

Fortinet Expertise, Applied to Your Environment

1. Architecture and design

Traffic flows, segmentation, HA, SD-WAN, and security features are aligned to operational priorities.

2. Deployment and validation

Changes are tested under realistic conditions. Behaviour under failure scenarios is understood before it matters.

3. Policy optimisation

Rule sprawl is reduced. Objects are rationalised. Logging and visibility are tuned.

4. Lifecycle and firmware strategy

Upgrades, support windows, and platform longevity are planned to avoid reactive change.

5. Ongoing optimisation

Performance, configuration drift, and evolving threats are reviewed regularly to maintain resilience over time.
