Network architecture design incorporating perimeter firewalls, internal segmentation and DMZ configurations aligned with your business needs.
Expert installation and hardened configuration of Fortinet FortiGate, Check Point and Palo Alto firewalls following security best practices.
Ongoing management including policy optimization, firmware updates, rule reviews and 24/7 health monitoring for your firewall estate.
Comprehensive review of existing firewall policies to identify rule bloat, redundant permissions and security gaps.
Seamless migration from legacy firewall platforms to next-generation solutions with minimal downtime and full policy transfer.
Firewall-as-a-Service (FWaaS) and cloud-native security groups for hybrid and multi-cloud environments.
A firewall is not a box, it is a rule set. The value of a deployment rests on how accurately it reflects real traffic requirements, which is why we spend more time on design than on installation.
We map who actually communicates with whom and which services must be reachable. We also review the existing rule set, typically a significant part of it is already redundant.
We divide the network into zones and design the permitted traffic between them. The goal is least privilege: what is not explicitly allowed is denied.
Phased cutover, initially in monitoring mode so that faulty rules surface before live blocking. A rollback plan accompanies every step.
Alert tuning, log integration into the SIEM, documentation and administrator training. We also hand over the rule review procedure.
We design vendor-independently: the solution is chosen to fit the environment and existing estate, not the other way round. We hold active partnerships and deployment experience with the vendors below.
| Area | Technology | Typical use |
|---|---|---|
| Perimeter NGFW | Fortinet, Check Point, SonicWall | Internet edge, branch network, VPN concentrator |
| Web application firewall | Barracuda, Fortinet | Protection against OWASP Top 10, public services |
| Industrial firewall / IPS | txOne EdgeFire, EdgeIPS | OT zone boundaries, virtual patching, protocol inspection |
| Internal segmentation | NGFW + VLAN / micro-segmentation | Isolating critical systems, blocking lateral movement |
| Remote access | IPSec / SSL-VPN + MFA | Remote work, supplier maintenance channels |
| Network access control | Genians NAC | Device identification, compliance-based admission |
Four signs point to it. If vendor support has expired or is about to, because there will be no security updates from then on. If hardware performance cannot handle encrypted traffic inspection, most traffic today is TLS, and without decryption you are effectively filtering blind. If the device cannot express application-level rules, only port-based ones. And if the rule set has grown so tangled that nobody dares touch it. The last case can often be handled without replacement: a rule review is enough.
No. The typical incident today starts with phishing or a stolen password, which by definition bypasses the perimeter, the attacker works from "inside". That is why internal segmentation matters: on a flat network, one compromised workstation reaches the entire organisation. The minimum is placing critical systems (domain controllers, backup infrastructure, financial systems) into their own segments. We covered this further in our Zero Trust guide.
Replacing a single site is typically 2–4 weeks from traffic analysis to handover, with the actual cutover taking one maintenance window. For multiple sites or a significant segmentation redesign, 6–12 weeks is realistic. Most of the time goes not on installation but on traffic analysis and rule design, that is what determines whether there is disruption after cutover.
This is why we work in phases and start in monitoring mode: the rule set logs but does not block at first, so faulty rules surface without live impact. Every step has a rollback plan and a time window. Cutover is followed by an observation period during which we tune remaining deviations.
No. A general-purpose firewall sees Modbus or S7comm traffic as a single TCP port, so it cannot distinguish a read from a write or a program download. Industrial environments need an OT-aware device that understands protocol function codes, enabling rules such as "from this segment PLCs may only be read". Virtual patching capability also matters, to protect devices that cannot be updated. We covered this in detail in our article on OT endpoint security.
