A correctly sized firewall, a segmented network, protected endpoints and a backup that has actually been restored from. In that order.
Security spending goes wrong when it is bought as products rather than as a design. A next-generation firewall protecting a flat internal network is a locked front door in a building with no internal walls.
We work through four layers in sequence: the perimeter (a properly sized firewall with inspection actually enabled), the internal network (segmentation so a compromised PC cannot reach the servers), the endpoint and mailbox (where most incidents begin), and recovery (an offline or immutable backup that has been restored from in a test).
Assessment, deployment and ongoing operation.
FortiGate installation, policy design, SSL inspection and hardening — sized from real traffic.
VLANs and inter-VLAN policy so servers, users, guests, cameras and production systems are separated.
Site-to-site and client VPN with multi-factor authentication for remote staff and branches.
Managed endpoint security across servers and workstations with central visibility.
Anti-phishing and attachment filtering, plus SPF, DKIM and DMARC records configured correctly.
3-2-1 backup design with an offline or immutable copy, and periodic restore testing.
Operating system and firmware update discipline across servers, endpoints and network devices.
A written review of perimeter, segmentation, endpoints, backup and admin access with ranked findings.
Containment, scope assessment and rebuild support following a security incident.
Turkish data protection law (KVKK) and, for companies handling EU personal data, the GDPR both require appropriate technical measures — not a specific product. In practice this means access control, logging, encryption where relevant, defined retention periods, and a demonstrable ability to recover.
We build these requirements into the design rather than bolting them on: camera retention periods set deliberately, logs retained and time-synchronised, administrative access individually attributable, and backup copies held where they cannot be encrypted along with the primary data.
No. A firewall stops what crosses the perimeter. Most successful attacks arrive through e-mail or a compromised credential and then move sideways inside the network. Segmentation, endpoint protection and a tested backup are what limit the damage.
From measured throughput, concurrent sessions and how much traffic needs inspecting once SSL inspection is switched on. Inspection is where undersized appliances fail, so we size for it rather than for the datasheet figure.
We examine the perimeter configuration, network segmentation, patch levels, endpoint protection coverage, backup design and administrative access. You receive a written report with findings ranked by risk.
Yes. The immediate priorities are isolating affected systems, establishing what was encrypted, and verifying which backups are clean. We can assist with all three and with rebuilding afterwards.
We review where you stand today and produce a prioritised plan.
