Network security with FortiGate is the deployment of an NGFW that combines traffic control, VPN, threat inspection, and segmentation in a single point. FortiGate is not just “an edge firewall”: when well designed, it separates networks, enforces policy by identity, and sustains continuity when a link or device fails.
What FortiGate solves
- Edge and perimeter: service publishing, NAT, and outbound control.
- Site-to-site VPN and remote access with centralized authentication.
- Segmentation: separate production, guests, OT, voice, and management.
- Threat inspection: IPS, antimalware, URL filtering, and sandbox (per license).
- SD-WAN and multiple links with failover and per-application policy.
- Visibility: logs, reports, and SIEM/ITSM integration.
What we assess when sizing
| Criterion | Why it matters |
|---|---|
| Throughput with inspection | Datasheet numbers without SSL are higher than real IPS/AV throughput |
| Concurrent sessions | Session exhaustion degrades performance before throughput does |
| SSL inspection | Encryption consumes processing and requires specific sizing |
| Interfaces and ports | Number of networks and future expansion |
| High availability | Active-passive pair and session synchronization |
| Licenses | FortiCare/FortiGuard define updates and security subscriptions |
How we implement it
- Discovery — topology, links, VLANs, published services, users, and critical flows.
- Design — zones, policies, NAT, VPN, inspection, and high availability.
- Rule migration — review the current firewall, remove orphan and any-any rules.
- Deployment and HA — pair configuration, synchronization, and failover tests.
- Validation — functional tests, logs, performance, and policy documentation.
- Operations — homologated firmware updates, configuration backup, and periodic review.
High availability and continuity
In critical environments, FortiGate is deployed as an HA pair with redundant links and a tested failover plan. The change window must consider sessions, VPNs, and published services — upgrading firmware without homologation and rollback is one of the most common causes of downtime.
Common mistakes
- Buying by datasheet maximum throughput and ignoring SSL inspection and sessions.
- Keeping “temporary” any-any rules that become permanent.
- Not segmenting guests, OT, and management.
- Deploying HA without testing failover and synchronizing sessions.
- Updating firmware without version homologation and configuration backup.
- Letting the FortiGuard subscription expire and losing signature updates.
Licensing
FortiGate licensing combines the appliance (or VM) with FortiCare (support and updates) and FortiGuard (security subscriptions). Nyverra supplies the license as a reseller through an authorized distributor, with an invoice and throughput-based sizing, and supports deployment and operations.
Why FortiGate
Benefits for security and operations
01
Perimeter and segmentation
Policies across VLANs, DMZ, and internet access with reviewable rules and change records.
02
IPS/IDS and filtering
Traffic inspection, known-threat blocking, and fine-tuning to reduce false positives.
03
VPN and remote access
SSL/IPsec for users and branches with MFA when the scope includes strong identity.
04
SD-WAN and high availability
Redundant links and documented failover for critical sites per the agreed design.
05
Centralized management
FortiManager/FortiAnalyzer when applicable—inventory, config backup, and audit reports.
06
Assisted operations
Runbooks, portal tickets, and periodic rule and firmware reviews.
