Best alternative to Lasso Security

For teams evaluating a best alternative to Lasso Security, this scanner is a self-service option that focuses on fast, black-box assessment of public-facing APIs. Unlike tools that require agents or code integration, it operates read-only against any endpoint that returns HTTP, making it applicable across languages and frameworks. Scan initiation is a single-submit workflow that returns a risk grade and prioritized findings in under a minute. It covers authentication bypass, authorization flaws, input validation, data exposure, and LLM-specific adversarial testing, while explicitly avoiding intrusive exploit attempts or remediation actions.

The scanner maps findings to three frameworks commonly referenced in audit contexts: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). It supports audit evidence for additional controls by surfacing issues such as misconfigured security headers, IDOR-prone numeric ID usage, missing rate limiting, PII leakage, and unsafe third-party webhook surfaces. Detection spans 12 categories, including authentication bypass, Broken Object Level Authorization, Broken Function Level Authorization, Property-Based Over-exposure, Input Validation, Rate Limiting & Resource Consumption, Data Exposure, Encryption, SSRF, Inventory Management, Unsafe Consumption, and LLM/AI Security with tiered adversarial probes.

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, deprecated operations, and missing pagination. Authenticated scans require domain verification via DNS TXT record or a well-known HTTP file to ensure only the domain owner can submit credentials. Supported auth methods include Bearer tokens, API keys, Basic auth, and Cookies, with a strict header allowlist of Authorization, X-API-Key, Cookie, and X-Custom-* headers.

The Web Dashboard centralizes scan management, report viewing, score trend tracking, and downloadable compliance PDFs. The CLI supports one-command scans with JSON or text output, suitable for local use or scripting. A GitHub Action enables CI/CD gating by failing builds when scores drop below a configurable threshold. An MCP Server allows scanning from AI coding assistants, and a programmatic API client facilitates custom integrations. Pro tier adds scheduled rescans, diff detection, email alerts, Slack and Teams notifications, and signed webhooks with failure auto-disable.

Scanning is read-only and destructive payloads are never sent. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer data is deletable on demand and retained for no longer than 30 days after cancellation; it is never sold or used for model training. This tool does not fix, patch, or block issues; it reports findings with remediation guidance. It does not perform active SQL or command injection testing, detect business logic vulnerabilities, or replace a human pentester for high-stakes audits. For other regulations, it helps you prepare for and supports audit evidence collection without asserting certification or guaranteed compliance.
