Sr. Cybersecurity Consultant IT/OT at EJADA
Compliance and cost-effectiveness have improved while critical infrastructure security adapts to evolving needs
ArcSight Logger fulfills compliance requirements and passes audit requirements. It is one of the Aramco standards requirements and is recommended by Aramco for any implementation. Aramco, SABIC, water companies, and electricity companies are critical infrastructure with air-gapped networks. In an air-gapped network, there is no communication going out from that network area to the outside world, even to the corporate network. ArcSight Logger is installed on minimal resources with minimal requirements. There are not many upgrades or new features that come up frequently, though they do occur occasionally.

Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.
