Authentication Guard Bundle Laravel Package

Product Decisions This Supports

• Security hardening backlog for legacy Symfony 2 estates. The only realistic use case is an existing Symfony 2.x application that needs brute-force and dictionary-attack protection on its login flow and cannot yet migrate. It informs a "patch now vs. accelerate migration" trade-off rather than a new-build decision.
• Build vs. buy on login throttling. The package's scope (failed-attempt tracking, lockout/delay on repeated authentication failures) is small enough that most teams should treat it as a reference design, not a dependency. A PM can use it to size the in-house alternative: typically a middleware/guard, a counter store (cache or DB), and a lockout policy — days, not weeks.
• Not a Laravel decision. Despite the framing, this is a Symfony 2 bundle, not a Laravel package. There is no Laravel integration path here; any Laravel-side need for login throttling maps to framework-native rate limiting, not to this repository.
• Policy inputs, not just code. Reviewing it surfaces the product questions worth deciding explicitly: lockout threshold, lockout duration, whether lockout is per-account or per-IP, user-facing messaging, and admin unlock/observability. Those decisions outlive the package.
• Roadmap signal. An archived 2017 bundle with 12 stars and zero dependents is evidence that the ecosystem solved this problem elsewhere. It supports deprioritizing any "adopt a library" workstream in favor of platform upgrade work.

When to Consider This Package

Consider it only when all of the following hold:

• You operate a Symfony 2.x application still in production, with a concrete migration date that is far enough out to justify interim risk reduction.
• You have an unmitigated brute-force exposure — no reverse-proxy rate limiting, no account lockout, no WAF — and need a short-term control.
• You can vendor the code or pin it and accept ownership: it is archived, last released September 2017, has no maintainer, no security response process, and will not receive patches.

Look elsewhere — or build in-house — when:

• You are on Symfony 3+/4+/5+/6+ or Laravel. Native rate limiting (symfony/rate-limiter, Laravel's RateLimiter/throttle middleware) covers the same ground with active maintenance.
• You are starting a new product. Do not introduce an archived Symfony 2 bundle into a greenfield codebase.
• You need auditable security posture (SBOM, CVE monitoring, supported-version guarantees). An abandoned package is a finding, not a mitigation.
• The requirement is broader than login: MFA, credential-stuffing detection, bot management, and breached-password checks are all out of scope here.

How to Pitch It (Stakeholders)

For executives: This is a small, abandoned 2017 component that protects a login page from password-guessing attacks. It is not a strategic dependency and we should not plan around it. Its only value is as a template for a control we can implement ourselves in a few days, or as a stopgap for a legacy Symfony 2 system we are already scheduled to retire. Recommendation: no investment; fund the platform upgrade instead.

For engineering: Treat the repository as a design reference for login throttling — attempt counting, lockout thresholds, per-account vs. per-IP scoping, and the failure-path UX. Do not add it as a dependency: it targets Symfony 2's guard system, is archived, has no maintenance or security response, and has zero downstream users to absorb breakage. If we need this behavior, implement it against the current framework's rate limiter, own the code, and add the policy values to our security baseline. If a legacy system genuinely needs cover before migration, vendor the logic and log it as accepted technical debt with an expiry tied to the migration date.
