What is Fortinet? The Leading Platform for Enterprise Network Security

What is Fortinet?

Fortinet is an American cybersecurity company founded in 2000 that currently holds a leading position in global NGFW market share. It serves more than 580,000 customers in over 60 countries and offers solutions across a broad spectrum, from enterprise network security to operational technology (OT) security.

The key differentiator that sets Fortinet apart from competitors is the Fortinet Security Fabric architecture: all Fortinet products operate in an integrated manner on a common platform, share threat intelligence, and enable centralized policy management.

The Foundation of Fortinet: FortiOS

The majority of Fortinet products run on the FortiOS operating system. FortiOS consolidates firewall, VPN, IPS, application control, web filtering, and SD-WAN capabilities under a single operating system. This approach eliminates the complexity of integrating products from multiple vendors.

FortiGate: Next-Generation Firewall

Fortinet's flagship product. It is one of the most widely adopted NGFW platforms worldwide. FortiGate leverages custom ASIC-based processors (NP and CP series) to deliver significantly higher throughput than competing solutions.

Core features of FortiGate:

• Deep packet inspection (DPI) — including TLS-encrypted traffic
• Application identification and control (5,000+ applications)
• Intrusion prevention (IPS)
• Web filtering and DNS security
• Anti-malware and sandbox integration (FortiSandbox)
• SSL-VPN and IPsec VPN
• SD-WAN (included in FortiOS, no additional license required)

Recommendations by scale:

Fortinet Security Fabric: An Integrated Platform

FortiGate is powerful on its own; however, Fortinet's true value lies in the integration of all its products working together.

FortiSwitch

Fortinet-managed network switches. Configured directly through FortiGate — no separate switch management platform required.

FortiAP

Centrally managed Wi-Fi access points. Policy enforcement through FortiGate or FortiWLC. Provides tight integration with FortiGate for enterprise wireless networking.

FortiClient (Endpoint)

VPN client, endpoint security, and ZTNA agent. Centralized management via FortiClient EMS.

FortiAnalyzer

Centralized log management, analysis, and reporting platform. Correlates logs from FortiGate and other Fortinet products for SOC operations.

FortiManager

Platform for centrally managing dozens or hundreds of FortiGate devices. Indispensable for large-scale deployments and MSPs.

FortiSIEM

Security information and event management (SIEM) platform. Analyzes logs collected from Fortinet and third-party sources.

FortiSandbox

Executes unknown files in an isolated environment to perform malware analysis. Integrates with FortiGate and FortiMail.

FortiMail

Email security gateway. Protection against spam, phishing, malicious attachments, and CEO fraud.

SD-WAN: Where Fortinet Excels

Fortinet consistently holds a leader position in Gartner's SD-WAN Magic Quadrant. The SD-WAN capability built into FortiGate requires no additional license.

Advantages of Fortinet SD-WAN:

• Application-based routing (priority bandwidth for critical applications)
• Load balancing across multiple WAN connections (fiber, xDSL, LTE)
• Seamless failover — automatic switchover to backup link upon connection loss
• Centralization of branch office management
• Security + SD-WAN in a single device — no separate SD-WAN appliance required

For Turkish organizations with multiple branch offices, SD-WAN reduces bandwidth costs while simultaneously enforcing security policies across all branches.

ZTNA (Zero Trust Network Access)

The combination of FortiGate and FortiClient supports a ZTNA architecture that replaces traditional VPN. Users are granted access only to authorized applications rather than broad network access; every connection undergoes identity and device verification.

Compliance with Fortinet

Fortinet products provide reporting and control mechanisms that support the following compliance standards:

• ISO 27001 — Log management, access control, and security incident records
• KVKK — Monitoring of personal data traffic and DLP integration
• PCI-DSS — Network segmentation and access control
• NIST Cybersecurity Framework — Detection, response, and recovery controls

FortiCare and FortiGuard: Support and Threat Intelligence

FortiCare: Hardware warranty, technical support, and software updates.

FortiGuard Labs: Fortinet's global threat intelligence service. Analyzing billions of threat events daily, it delivers IPS signatures, web filtering categories, antivirus updates, and sandbox data to FortiGate in real time.

A FortiGate without a FortiGuard subscription loses the majority of its threat prevention capabilities — this must always be considered in license planning.

Who Should Use Fortinet?

• Multi-branch organizations: Ideal for SD-WAN and centralized management
• High-traffic networks: Unrivaled throughput with ASIC-based processors
• OT/industrial security: Fortinet's dedicated OT solutions (FortiNAC, FortiDeceptor)
• Organizations seeking a comprehensive security fabric: Switch, AP, endpoint, and SIEM on a single platform
• MSPs and managed service providers: FortiManager multi-tenant management

Conclusion

Fortinet is one of the most powerful platforms in the enterprise market, particularly in terms of network security and SD-WAN performance. FortiGate's ASIC architecture delivers noticeably higher throughput at the same price point compared to competing products. The Security Fabric architecture makes it possible to manage multiple security layers from a single console. As an authorized Fortinet partner, NRC Sistem provides support for FortiGate, FortiSwitch, FortiAP, and FortiAnalyzer deployment, licensing, and managed services.
