Case Study: SEMrush achieves confident, scalable growth and attack protection with Wallarm

How Semrush Grows Its Seo Business With Confidence

Semrush, a leading competitive research service for online marketing, needed a modern, adaptive web-security solution that could block a variety of web attacks, fit unusual application features, and scale with rapid infrastructure growth—while providing professional, fast support. Semrush selected Wallarm and its filtration nodes (deployed as NGINX dynamic software modules) to meet these requirements.

Wallarm was deployed into staging for functional and load testing, underwent AI training, and was switched into blocking mode, with Wallarm technical support tuning the solution to Semrush’s environment; over 14 months Semrush expanded the number of filtration nodes to match growth. Wallarm immediately protected Semrush from brute-force attacks, flagged vulnerabilities that were quickly remediated (significantly reducing exploitation risk), and delivered ongoing visibility and fast support, meeting the company’s security needs as it scaled.
