According to a recent LinkedIn post from StackHawk, the company is highlighting expanded support in its dynamic application security testing platform to cover JSON-RPC APIs. The post explains that JSON-RPC is widely used in areas such as blockchain nodes, microservices, IoT backends, and emerging MCP infrastructure, yet is often skipped by traditional DAST tools due to its single-endpoint architecture.

The LinkedIn content describes a method-definition–based approach in which users provide a specification similar to OpenAPI, enabling StackHawk to fuzz parameters across JSON-RPC methods for issues such as injection, path traversal, SSRF, and command execution. By positioning its scanner to handle REST, GraphQL, SOAP, gRPC, and now JSON-RPC, the post suggests StackHawk is broadening its addressable market in security testing and could strengthen its competitive standing among DevSecOps-focused vendors.
For investors, this feature emphasis points to continued product investment aimed at complex, high-value workloads like blockchain and distributed systems that typically carry heightened security risk. If adopted by security-conscious engineering teams in those segments, the enhancement could support higher usage intensity, more compelling enterprise value propositions, and potentially improved pricing power over time.
