Memory Safety.
Without the Rewrite.
Rust prevents entire categories of security vulnerabilities at the language level. Pure gives your existing Node.js applications those guarantees — without changing a line of code.
The Memory Safety Problem
The majority of critical vulnerabilities share a common root cause.
Buffer Overflows
Writing data beyond allocated memory bounds. One of the most exploited vulnerability classes in software history, enabling arbitrary code execution.
Use-After-Free
Accessing memory after it has been freed. Attackers exploit this to corrupt data structures, hijack control flow, or execute arbitrary code.
Null Pointer Dereferences
Attempting to access memory through an invalid pointer. Can cause crashes, denial of service, or in some contexts, exploitable conditions.
Data Races
Concurrent access to shared memory without synchronization. Can lead to unpredictable behavior, data corruption, and security vulnerabilities.
These aren’t theoretical risks. They account for approximately 70% of critical security vulnerabilities in major software systems, according to Microsoft, Google, and other industry leaders.
Why Rust Prevents This
These protections are built into the language itself — not bolted on after the fact.
Ownership Model
Every piece of data in Rust has exactly one owner at a time. When the owner goes out of scope, the data is automatically cleaned up. This eliminates use-after-free and double-free vulnerabilities by design.
Borrow Checker
Rust's compiler enforces strict rules about how references to data can be shared. You can have many readers or one writer — never both. This prevents data races and buffer overflows at compile time.
No Null Pointers
Rust doesn't have null. Instead, it uses an explicit Option type that forces you to handle the absence of a value. Null pointer dereferences simply cannot occur.
Compile-Time Guarantees
These aren't runtime checks that can be bypassed — they're enforced at compile time by the Rust compiler. If your code compiles, these categories of vulnerabilities are eliminated.
Pure’s Role
Gain Rust’s security guarantees for your existing applications.
Your code, Rust's safety model
Pure converts your existing JavaScript or TypeScript application to a native Rust binary. Your application logic is preserved exactly — but it now runs within Rust's memory safety guarantees.
No runtime vulnerabilities
By running as a native Rust binary instead of on the Node.js runtime, your application is no longer exposed to runtime-level vulnerabilities. You remove the runtime from the equation entirely.
What it doesn't solve
Rust prevents memory safety vulnerabilities, not logic bugs. If your application has a flawed authentication check or an insecure API design, Pure preserves that logic exactly as-is. Pure makes your application memory-safe — not bug-free.
Industry Guidance
Governments and industry leaders are recommending memory-safe languages.
of critical security vulnerabilities in major software systems are memory safety issues — buffer overflows, use-after-free, null pointer dereferences, and similar flaws.

memory safety vulnerabilities are possible in safe Rust code. Rust’s ownership and borrowing system prevents these at compile time — this is a property of the language’s type system, not a claim.
