  • Choose which methods to protect
  • Optional string protection
Native applications

Blackout (Native)

Protect selected regions of native applications with code and string protection, plus anti-tampering safeguards.

  • Windows, macOS, and Linux support
  • Compatible with x64 binaries
  • Select the code regions to protect

Blackout (Java)

Blackout replaces the methods you choose with protected code that only its own runtime can execute. Decompilers have nothing meaningful to show, and your application behaves as before.

  • From Java 4 to 27
  • JAR in, JAR out
  • No source code needed

Code virtualization

Selected methods no longer exist as standard JVM bytecode, so tools like CFR, Vineflower, and Procyon have nothing to reconstruct.

Unique per method

Each protected method is encoded differently, so what an attacker learns from one does not carry over to the next.

Encrypted and verified

Protected code is secured with robust encryption and stays encrypted until it runs. Tampered code is detected and refused.

String protection

Optionally keep keys, endpoints, and messages out of static analysis.

Decompiler disruption

Optional measures that make common decompilers fail or produce unusable output.

You choose the scope

Protect everything eligible, mark specific methods with an annotation, or exclude packages and classes.

Virtualized code is interpreted, so protect the logic that matters and leave performance-critical paths untouched.

Blackout (Native)

Blackout replaces the code regions you choose with protected code that only its own embedded runtime can execute. Disassemblers and decompilers have nothing meaningful to show, and your application behaves as before.

  • Windows, macOS, Linux
  • x64 today · arm64 & riscv64 coming soon
  • Same format in and out

Code virtualization

Selected code no longer exists as standard machine instructions, so disassemblers and decompilers have nothing to reconstruct.

Unique per build

Every protected build uses a fresh instruction encoding, so what an attacker learns from one build does not carry over to the next.

Encrypted and verified

Protected code is secured with robust encryption, and tampered code is detected and refused before it can run.

String protection

Optionally keep keys, endpoints, and messages out of static analysis.

You choose the scope

Mark the regions to protect with a lightweight SDK header, rebuild, then run Blackout on the compiled output. Everything else stays native and fast.

Fits your build pipeline

Blackout takes your compiled executable and returns the same format, protected and ready to ship.

Virtualized code is interpreted, so protect the logic that matters and leave performance-critical paths untouched.
