Case Study: Grammarly achieves faster time-to-market and real-time security and performance visibility with Sumo Logic

Grammarly powers its high-growth business with real-time data insights that speed time to market

Grammarly, used by about 30 million people daily, needed real-time visibility into application performance and security across its AWS environment to maintain a high-quality, rapidly growing SaaS offering. An open-source logging approach required heavy maintenance and failed to scale for multiple engineering teams (development, security, infrastructure), so Grammarly sought a cloud-based, user-friendly analytics solution that could handle large ingest volumes and simplify operations.

Grammarly selected Sumo Logic’s cloud Continuous Intelligence Platform, which now ingests and analyzes ~3.7 TB of data per day across 400+ microservices, providing full‑stack, real‑time insights and security dashboards. The move eliminated operational overhead, improved product quality and time‑to‑market, gave the security team a go‑to view of the attack surface, and—through tiered analytics and licensing—helped optimize data management costs.
