Protect your Windows software from reverse engineering

Make every copy of your binary unique.

Without code virtualization, an attacker who reverses one copy of your software has reversed every copy. AkiProtect's virtual machine replaces your code with custom bytecode that runs on a tiny CPU baked into the runtime — and the instruction set is randomized for every single build. A patch that works against one copy fails against the next. Cracking groups can't release "a working keygen for your product" — they have to crack each shipment from scratch.

Make tampering with your binary impossible.

Even if an attacker manages to extract your protected payload, AkiProtect's block layout prevents them from reassembling it into a working file. Encrypted blocks are scattered via a mathematical spiral and bound with cryptographic hashes — change a single byte and the runtime refuses to start. This blocks the standard cracking workflow of dump, patch, repack. The pirate's "modified version" simply does not run.

Stop reverse engineers before they get started.

Every serious reverse engineer reaches for a debugger first — it's the tool that lets them step through your code line by line and understand what makes your product valuable. AkiProtect runs six independent checks before any of your code executes. When a debugger is detected, your software exits silently with no error message, no diagnostic information, no clue what triggered it. The attacker is left guessing whether they hit a bug or a defence.

Detect any modification to your binary.

Crackers don't just read your software — they modify it. They patch out license checks, bypass activation, remove trial limits. AkiProtect's runtime checks itself for modification on every start-up by comparing a cryptographic hash of its own code against a value embedded at build time. If anything has changed — even a single byte — the binary terminates silently before your code ever runs. The patched copy looks identical to a working one until the user double-clicks it.

Stop attackers from extracting your running code.

A common reverse-engineering shortcut is to wait until your software unpacks itself in memory, then dump the running process to disk and analyse the clean code that's now exposed. AkiProtect wipes the most useful parts of your binary out of memory immediately after the runtime hands control to your code. A memory dump captured at that point is no longer a directly-loadable executable — the attacker has to reconstruct the missing structures themselves before they can disassemble anything.

Strip every readable clue from your binary.

Reverse engineering often starts by reading the strings inside a binary — error messages, debug labels, license URLs, API endpoints. They are the breadcrumbs that tell an attacker what your software does and where to look first. AkiProtect encodes every string at compile time with a different mask for every build. Anyone running the standard 'strings' tool on your file sees nothing but garbage. The attacker loses the easiest source of orientation.

Hide what your binary will do before it runs.

Every Windows executable normally lists the operating-system functions it intends to call — its 'import table'. Reverse engineers read this list first to predict what your software is about to do. AkiProtect's runtime stub has no import table at all. An attacker who opens your packed file in a disassembler sees a tiny, empty import directory and has no idea whether your code will read files, talk to the network, draw a window, or do something else entirely.
