Key responsibilities include managing and enhancing a diverse security stack, including Palo Alto firewalls, Darktrace, Proofpoint, Varonis, Qualys, Infoblox, and Cloudflare. The analyst will operate within a Microsoft hybrid Azure environment, ensuring secure integration between on-premises and cloud systems.
A core function of the role is to configure, tune, and optimize XDR/SIEM platforms, including rule creation, alert correlation, and log ingestion, to improve detection accuracy and reduce false positives.

The role also includes project-based work, focused on implementing, configuring, and continuously improving security controls and detection capabilities across the environment.
The ideal candidate brings strong analytical and troubleshooting skills, hands-on experience across security technologies, and a proven ability to fine-tune detection logic.
