Alternatives to Lasso Security

Organizations evaluating API security tools often compare scanner capabilities, deployment models, and coverage of the OWASP API Top 10. This overview presents alternatives to Lasso Security, highlighting approaches that vary in integration depth, scan methodology, and target use cases. The entries below describe viable options, including a self-service black-box scanner that emphasizes speed, broad OWASP coverage, and CI/CD integration.

A self-service scanner that requires no agents, SDKs, or code access. You submit a target URL and receive a risk score with prioritized findings within a minute. The scan uses read-only methods (GET and HEAD) plus text-only POST for LLM probes. It operates without accessing runtime infrastructure, making it suitable for environments where instrumentation is restricted.

Findings map directly to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). Detection coverage includes authentication bypass, JWT misconfigurations such as alg=none and expired tokens, BOLA and IDOR via sequential ID probing, BFLA and privilege escalation attempts, over-exposed properties, input validation issues like CORS wildcard misuse, rate-limit header detection, sensitive data exposure including PII and API keys, encryption misconfigurations, SSRF probes on URL-accepting endpoints, inventory issues like missing versioning, unsafe consumption surfaces, and LLM security probes across multiple tiers.

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 files with recursive $ref resolution, cross-referencing spec definitions against runtime behavior to identify undefined security schemes or deprecated operations. Authenticated scanning supports Bearer, API key, Basic auth, and cookies, gated by domain verification via DNS TXT or HTTP well-known files. Only a restricted set of headers is forwarded to limit credential exposure.

A web dashboard centralizes scan management, score trends, and downloadable compliance PDFs. The CLI allows on-demand scans with structured output. A GitHub Action enforces quality gates in CI/CD, failing builds when scores drop below defined thresholds. An MCP server enables scanning from AI coding assistants. Programmatic access via API supports custom integrations, while scheduled rescans and diff detection provide continuous monitoring with HMAC-SHA256 signed webhooks.

Free tiers offer limited monthly scans, with paid tiers scaling by API count and including monitoring, integrations, and compliance reporting. Safety measures include read-only execution, blocking of private and metadata endpoints, and user-initiated data deletion with defined retention windows. The scanner does not perform intrusive exploit testing, fix issues, detect business logic flaws, or replace human pentesters for high-assurance audits.
