Building secure networks since 2010
At Sysnet Yazılım, we ease Türkiye's Law 5651 compliance burden with SignLogger — a unified platform combining enterprise log management, signed log archiving and network access control.
About Us
An industry-agnostic, scale-agnostic brand from Türkiye
SignLogger, developed by Sysnet Yazılım Ltd. Şti., is an integrated platform that collects every log produced across your network and security infrastructure in one place, archives those records in compliance with Law 5651 using digital signatures and timestamps, and makes guest networking (hotspot / captive portal) and NAC (RADIUS) based access control manageable from a single panel.
Our starting point was a simple observation: organizations were forced to run separate, separately licensed and separately managed products for log collection, reporting, guest Wi-Fi and network access control. SignLogger unifies all of it in one interface, one data model and one license — significantly reducing both total cost of ownership and operational load.
The platform collects records from firewalls, switches, wireless controllers and servers over syslog, API and SSH, normalizes them, indexes them for fast search and converts them into signed archives for long-term retention. The hotspot and NAC modules authenticate every user and device joining the network — so the question "who produced this record?" is answered with certainty. It is vendor independent, from FortiGate to Mikrotik, Sophos to Cisco.
Legal compliance is not an afterthought but the center of the design: every archive is signed automatically, retention policies are configured per day, and the independent log verification tool proves within seconds that records have not been altered. When an audit or judicial request arrives, the relevant records are located in minutes and presented as signed archives — a ready reporting routine instead of a document-hunting scramble.
Today hotel chains run their guest Wi-Fi on our Elektraweb and Opera Cloud integrations; hospitals, universities and dormitories handle heavy guest traffic with SMS and sponsor-verified captive portals; public institutions add a 2FA layer to SSLVPN and Windows Login; and managed service providers (MSPs) operate multiple customers from one platform with the multi-domain architecture.
Behind SignLogger — the choice of more than 1,000 organizations across Türkiye — stands an engineering team that stays with you from installation to training and ongoing support. Whatever your scale or industry, we are one phone call away.
