Case Study: Seismic achieves continuous, automated API security and major cost savings with APIsec

Seismic Comprehensive and Continuous API Security

Seismic, a leader in sales and marketing enablement that handles sensitive client data, faced growing security risks after moving to an API-driven model. Their manual penetration tests and legacy scanners covered only 10–20% of APIs and cost $15,000–$20,000 per engagement (about $200k/year), so Seismic engaged APIsec for automated, always-on API vulnerability and business-logic testing.

APIsec automated onboarding from Seismic’s Swagger definition, delivered an API risk discovery scan within 24 hours, and built AI-driven feature maps and custom attack vectors to continuously test RBAC/ABAC, logic flaws, DoS and injection scenarios in the CI/CD staging environment. APIsec replaced recurring manual pentests, found a wider range of vulnerabilities faster, shifted security left into the development pipeline, boosted customer confidence, and paid for itself in less than three months while eliminating the ~ $200k/year testing expense.
