Alternatives to Akto at Series A startups

Unlike tools that require instrumentation, this scanner operates as a black-box solution. You submit an API endpoint URL and receive a risk score with prioritized findings. No agents, SDKs, or code access are required, and it supports any language, framework, or cloud environment. Scan completion typically occurs in under a minute, using read-only methods (GET and HEAD) plus text-only POST for LLM probes.

The scanner covers 12 categories aligned to OWASP API Top 10 (2023). It detects authentication bypass and JWT misconfigurations such as alg=none, HS256, expired tokens, missing claims, and sensitive data in claims. Other areas include BOLA and IDOR via sequential ID enumeration, BFLA and privilege escalation through admin endpoint probing, property authorization over-exposure, input validation issues like CORS wildcard usage and dangerous HTTP methods, rate limiting and resource consumption signals, data exposure patterns including PII and API key formats, encryption misconfigurations, SSRF indicators in URL and body fields, inventory issues like missing versioning, unsafe consumption surfaces, and LLM/AI security probes across multiple tiers.

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, cross-referencing spec definitions against runtime findings to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination. For authenticated scanning, Bearer, API key, Basic auth, and Cookie methods are supported after domain verification via DNS TXT or HTTP well-known file. Only a restricted set of headers is forwarded, and the Starter tier and above include dashboard reporting, email alerts, and MCP Server access.

Pro tier adds scheduled rescans at intervals such as 6 hours, daily, weekly, or monthly, with diff detection for new findings, resolved findings, and score drift. Alerts are rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks auto-disable after 5 consecutive failures. Integrations include a Web Dashboard for reports and trends, a CLI via an npm package with JSON or text output, a GitHub Action for CI/CD gating, an MCP Server for AI coding assistants, and a programmable API for custom workflows.

The scanner uses read-only methods only and never sends destructive payloads. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer data is deletable on demand and purged within 30 days of cancellation, and it is never sold or used for model training. Note that the tool does not fix, patch, block, or remediate. It does not perform active SQL injection or command injection testing, detect business logic vulnerabilities, detect blind SSRF, or replace a human pentester for high-stakes audits. It detects and reports with remediation guidance.
