Overview

FortiNAC

FortiNAC gives you complete visibility and control over everything on your network. As your environment grows with IoT devices, BYOD, and guest users, you can automatically identify and profile every single endpoint the moment it tries to connect. You no longer have to wonder what is on your wire or in your air; the system sees it all and applies your security policies instantly.

You can implement micro-segmentation to ensure devices only access the specific resources they need, significantly reducing your attack surface. If a device starts behaving strangely or becomes compromised, the platform can automatically quarantine it or kick it off the network without you lifting a finger. It works across your existing switches and wireless access points, making it a flexible choice for securing complex, multi-vendor infrastructures.

Graylog

Graylog provides you with a centralized location to collect and explore your log data from across your entire infrastructure. Instead of manually searching through individual server logs, you can aggregate everything into a single interface to troubleshoot application errors, monitor system performance, and detect security threats in real-time.

You can build custom dashboards to visualize trends and set up automated alerts that notify you the moment specific criteria are met. Whether you are managing a few servers or a massive enterprise network, the platform helps you reduce mean time to resolution (MTTR) by making your data searchable and actionable through a high-performance engine.
