Defence is used principally to: 1. 🛡️ Prevent a suspicious-looking request getting deeper into an application's code and potentially exploiting vulnerabilities. 2. 🌱 Avoid wasting further system resources on unfriendly user activity. Recently, we have found Defence to be been extremely helpful in quickly mitigating the effects of *overzealous* bots, particularly those involved in information-gathering for AI. Excessive and/or faulty requests can negatively affect the experience of other users of the system and waste resources—including electricity. Warning **Defence does not eliminate the need to filter user-input in your application.** While some of the included filters do indeed validate user input, they take a very high-level view. Their aim is to detect *obviously* suspect values given a very basic understanding of what they're looking at. For example, the included ID-parameter filter knows only that certain parameters must contain only digits or a blank; the filter is useful because it can quickly and easily prevent SQL injection, but the value may still be invalid as far as your app is concerned. We recommend you read [Architecture](doc/architecture.md) before [Getting Started](doc/getting-started.md). Otherwise, [the documentation starts here](doc/README.md). ### Health Score 32 — LowBetter than 72% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity25 Limited adoption so far Community11 Small or concentrated contributor base Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 78.6% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~235 days Total 4 Last Release 776d ago Major Versions v8.0.1 → v9.0.02023-11-27 v9.0.0 → v10.0.02024-04-02 PHP version history (2 changes)v8.0.0PHP ^7.4|^8.0 v10.0.0PHP ^8.1 ### Community Maintainers ![](https://www.gravatar.com/avatar/fb4422c02b29b1ae4a4746abb1ebf16c0216d5fc62cf0604e7c6aa4de974b39b?d=identicon)[danbettles](/maintainers/danbettles) --- Top Contributors [![danbettles](https://avatars.githubusercontent.com/u/736672?v=4)](https://github.com/danbettles "danbettles (11 commits)")[![RichAtPowderBlue](https://avatars.githubusercontent.com/u/47561048?v=4)](https://github.com/RichAtPowderBlue "RichAtPowderBlue (3 commits)") --- Tags crackingcracking-attemptsfirewallintrusion-detectionintrusion-detection-systemintrusion-preventionintrusion-prevention-systemmalicious-requestssql-injectionsql-injection-attackssuspicious-requestsrequestloggingvalidationinjectionidsfilterhackintrusionipsmaliciouspreventioncracksuspicious ### Code Quality TestsPHPUnit Static AnalysisPHPStan Code StylePHP\_CodeSniffer Type Coverage Yes ### Embed Badge ![Health badge](/badges/danbettles-defence/health.svg) ``` [![Health](https://phpackages.com/badges/danbettles-defence/health.svg)](https://phpackages.com/packages/danbettles-defence) ``` ### Alternatives [sentry/sentry PHP SDK for Sentry (http://sentry.io) 1.9k227.1M273](/packages/sentry-sentry)[rollbar/rollbar Monitors errors and exceptions and reports them to Rollbar 33723.7M82](/packages/rollbar-rollbar)[nelmio/js-logger-bundle Adds logging of JS errors in your Symfony application 1761.2M](/packages/nelmio-js-logger-bundle)[open-telemetry/api API for OpenTelemetry PHP. 1933.0M214](/packages/open-telemetry-api)[open-telemetry/sdk SDK for OpenTelemetry PHP. 2322.9M248](/packages/open-telemetry-sdk)[honeybadger-io/honeybadger-php Honeybadger PHP library 381.5M4](/packages/honeybadger-io-honeybadger-php) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
