Limit Number Calls Bundle Laravel Package

Product Decisions This Supports

• Rate Limiting for API/SMS Services: Enables granular control over request volumes (e.g., SMS gateways, login attempts, or payment processing) to prevent abuse while maintaining business SLAs.
• Security Hardening: Mitigates brute-force, dictionary, or credential-stuffing attacks by enforcing configurable thresholds (e.g., "10 SMS per minute per phone number").
• Build vs. Buy: Avoids reinventing rate-limiting logic; leverages a battle-tested Symfony bundle with Redis-backed performance (microsecond precision).
• Compliance/Regulatory Needs: Supports GDPR/PCI-DSS requirements by restricting automated requests (e.g., blocking bots scraping phone numbers).
• Monetization Controls: Protects revenue streams (e.g., limiting free-tier API calls or promotional SMS blasts).
• Observability: Provides CLI tools for auditing blocked requests/statistics, useful for post-mortems or fraud investigations.

When to Consider This Package

Adopt if:

• Your Symfony 2/3 app handles high-volume, repeatable actions (e.g., SMS, logins, webhooks) vulnerable to abuse.
• You need fine-grained rules (e.g., "3 attempts per 1800ms for IP + endpoint combo").
• Redis is already in your stack (or you’re willing to add it for low-latency rate limiting).
• You require Symfony Security Voter integration for seamless ACL-like enforcement.
• Your team lacks bandwidth to build/maintain a custom rate-limiting system.

Look elsewhere if:

• You’re not using Symfony 2/3 (though core logic could be extracted).
• You need distributed rate limiting across non-Redis backends (e.g., database, Memcached).
• Your use case requires dynamic throttling (e.g., machine-learning-based adjustments).
• You prioritize open-source maturity (this package has low stars/activity; vet forks or alternatives like symfony/rate-limiter).
• You need UI dashboards for real-time monitoring (this is CLI-only).

How to Pitch It (Stakeholders)

For Executives: "This bundle lets us automatically block abusive request patterns (e.g., spam SMS, brute-force logins) without manual intervention. By enforcing rules like ‘10 messages/minute per phone number,’ we’ll protect our systems from fraud, reduce costs (e.g., SMS fees), and comply with regulations—all with minimal dev effort. It’s like a ‘circuit breaker’ for our APIs, using Redis for near-instant response times."

Key Outcomes: ✅ Reduce abuse costs (e.g., blocked spam SMS saves $X/month). ✅ Improve uptime by preventing overload from bad actors. ✅ Future-proof security with configurable, auditable rules.

For Engineering: *"This is a Symfony-native rate-limiter with Redis backend, offering:

• Microsecond-precision rules (e.g., time_period: 1800000 for 1.8s windows).
• Grouped policies (e.g., apply ‘sms_group’ rules to all SMS endpoints).
• CLI tools to inspect/clear blocks (e.g., avtonom:limit-calls:status).
• Security Voter integration for seamless ACL-like checks.

Tradeoffs:

• Requires Redis (but we already use it for caching).
• Symfony 2/3 only (but core logic could be extracted if needed).
• Low community activity (but MIT-licensed and functional).

Proposal: Pilot on our SMS API to block spam; expand to login endpoints if successful."*

For Security/Compliance: *"This addresses:

• Brute-force attacks (e.g., lock IPs after 5 failed logins).
• Scraping/bots (e.g., limit API calls per endpoint + IP).
• Audit trails via CLI commands to review blocked requests.

Example Rule:

login_attempts:
  time_period: 30000000  # 30s
  maximum_number: 5
  blocking_duration: 3600  # 1h ban
  subject_method: [getIp, getUsername]
```"*
