Traceable API Security
@fastify/rate-limit is a free API security solution. Traceable API Security is a commercial API security solution by Harness. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about the one we picked.
Best for: Dev-forward teams securing microservices and GenAI APIs end-to-end
The main gap in the database record is integrations: the data shows none listed, which is unusual for an enterprise platform and worth probing in a vendor conversation. Deployment is cloud-only, which rules it out for on-premises or air-gapped environments. For cloud-native teams building on microservices and containers who want security woven into the SDLC rather than bolted on at the perimeter, Traceable is a strong candidate.
