Alternatives to Astra in Fintech

This scanner operates as a black-box solution. You submit an API endpoint URL and receive a risk score from A to F with prioritized findings. It requires no agents, SDKs, or code access and supports any language, framework, or cloud. The scan completes in under a minute using read-only methods (GET and HEAD) and text-only POST for LLM probes.

The scanner covers 12 categories aligned to OWASP API Top 10 (2023). Relevant findings map to PCI-DSS 4.0 and SOC 2 Type II controls, surfacing issues such as authentication bypass, JWT misconfigurations, broken object level authorization, privilege escalation, sensitive data exposure, and input validation weaknesses. It also detects CORS misconfigurations, unsafe HTTP methods, debug endpoints, rate-limit header disclosure, PII and card data patterns, exposed API keys, missing encryption protections, SSRF indicators, missing versioning, and unsafe third-party webhook surfaces.

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, cross-referencing spec definitions against runtime findings such as undefined security schemes or deprecated operations. Authenticated scanning is available from the Starter tier upward, supporting Bearer, API key, Basic auth, and Cookie. Domain verification is enforced so only the domain owner can scan with credentials, and a strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.

Pro tier provides scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection to highlight new findings, resolved findings, and score drift. Alerts are delivered via email at a rate-limited frequency of 1 per hour per API, and HMAC-SHA256 signed webhooks can auto-disable after 5 consecutive failures. Integrations include a web dashboard for reports and score trends, a CLI with JSON or text output, a GitHub Action that fails the build when the score drops below a threshold, an MCP server for AI coding assistants, and a programmable API for custom workflows.

The scanner includes an LLM security module that runs 18 adversarial probes across three scan tiers: Quick, Standard, and Deep. These probes test for system prompt extraction, instruction override, DAN and roleplay jailbreaks, data exfiltration, cost exploitation, encoding bypasses, translation-embedded injection, few-shot poisoning, markdown injection, multi-turn manipulation, indirect prompt injection, token smuggling, tool abuse, nested instruction injection, and PII extraction. The tool does not fix, patch, block, or remediate findings; it reports with remediation guidance. It does not perform active SQL injection or command injection, does not detect business logic vulnerabilities, does not detect blind SSRF, and does not replace a human pentester for high-stakes audits.

Scan data is deletable on demand and purged within 30 days of cancellation. Customer data is never sold and is not used for model training. The pricing tiers are Free with 3 scans per month and CLI access, Starter at 99 dollars per month for 15 APIs with dashboard and email alerts, Pro at 499 dollars per month for 100 APIs with continuous monitoring and CI/CD integration, and Enterprise at 2000 dollars per month for unlimited APIs, custom rules, SSO, audit logs, SLA, and dedicated support. These options help you prepare for security reviews and align with security controls described in common financial sector assessments.
