Enterprise Exploit Protection for Modern Minecraft Servers[/CENTER]
ALTAR Sentinel is built for server owners who want stronger protection against illegal items, creative abuse, crash payloads, dangerous NBT, packet exploits, and inventory-based attacks.
By validating unsafe items, monitoring creative actions, sanitizing dangerous metadata, and protecting inventories before exploits spread, ALTAR Sentinel helps keep large SMP, survival, creative, factions, lifesteal, and public servers safer.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PROTECTION THAT WORKS BEFORE EXPLOITS SPREAD
Many Minecraft exploits rely on items, metadata, inventory actions, or packets that should never be trusted. ALTAR Sentinel focuses on detecting and sanitizing those risks before they can cause crashes, dupes, bypasses, or server instability.
ALTAR Sentinel includes layered protection for illegal items, creative abuse, unsafe NBT/components, impossible enchantments, malformed inventory actions, suspicious entities, and packet-level exploit attempts when ProtocolLib is installed.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CORE FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
SUPPORTED PLATFORMS
ALTAR Sentinel is built as one universal jar with automatic platform detection, scheduler abstraction, and graceful feature fallback.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CREATIVE CONTROL
ALTAR Sentinel includes a Creative Control engine designed to reduce creative-mode abuse and illegal item creation.
Without the correct bypass permission, creative players cannot freely create or keep restricted items. This helps prevent staff abuse, accidental illegal item leaks, creative duplication, and unsafe item injection.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
ADMIN MODERATION GUI
ALTAR Sentinel includes an in-game moderation GUI for staff. Use it to review alerts, trigger scans, inspect protection status, and access moderation tools faster.

DEPENDENCIES

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CONFIGURATION
ALTAR Sentinel uses modular YAML configuration files so server owners can tune each protection layer separately.
You can configure illegal item lists, creative restrictions, packet settings, entity limits, webhook alerts, punishments, plugin-safe behavior, and more.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PLUGIN COMPATIBILITY
ALTAR Sentinel is designed to be careful around custom item plugins. Items with trusted plugin namespaces are preserved by default unless they trigger high-risk exploit checks such as illegal materials, overstacking, crash books, malformed payloads, or dangerous creative behavior.
This helps protect your server without breaking legitimate custom items from plugins such as ItemsAdder, Oraxen, MythicMobs, Eco, MMOItems, and similar systems.

WHO IS ALTAR SENTINEL MADE FOR?
ALTAR Sentinel is made for server owners who want stronger protection against illegal item abuse, creative exploits, crash payloads, unsafe inventories, and exploit attempts.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
IMPORTANT NOTE
No protection plugin can honestly guarantee perfect protection against every private exploit, custom client, or future Minecraft vulnerability. ALTAR Sentinel is designed to reduce risk by validating, sanitizing, blocking, and logging dangerous behavior before it can spread across your server.
The plugin is configurable so server owners can balance security, compatibility, gameplay feel, and performance for their own server.
