OpenBSD

OpenBSD is an open-source, Unix-like operating system based on the Berkeley Software Distribution (BSD). It was created with a focus on security, code correctness, and simplicity. OpenBSD’s development prioritizes secure coding practices, and it has built-in features such as strong cryptography, secure networking, and code auditing, which make it a popular choice for environments where security is a top priority. Its codebase undergoes rigorous review to prevent vulnerabilities, and every update includes security enhancements. OpenBSD is known for its emphasis on correctness in software, ensuring that programs are designed and implemented to work as intended, reducing the chances of bugs or failures. It also includes tools for network security and encryption, such as the OpenSSH server and client, which are widely used across various systems for secure communications. Although OpenBSD may not have the same level of software compatibility or popularity as other operating systems like Linux, its reputation for security and stability makes it an ideal choice for servers, firewalls, and security-critical applications.
