I build secure web servers, secure mail servers, implement Server Security/Hardening, security-focused Nginx, php-fpm, SQL, FTP, SSH/SSL, DNS optimizations. For Web servers; I prefer FreeBSD operating system, that's fastest server OS for web servers (Netflix, WhatApp, Instagram running on it), fully hardened and optimized manually by me for web server performance, with unlimited&valid and verified free SSL certs (and automatically renewed), secure DNS servers with DNSSEC/CAA, security-based PHP/Nginx/SQL optimizations. I deploy encrypted secure mail servers (POP3S, IMAPS, SMTPS/TLS with MTA-STS/DANE) including; a strong Spam protection, antivirus running behind, over OpenBSD OS (considered as the most secure OS for servers), SPF, Reverse PTR record (a critical need for a healthy mail server), DMARC, DKIM and any other additional technical rules (helping your emails to not get marked as Spam) implemented, a secure Webmail Interface + Mail User/Domain/Server Administration interface, by entirely open-source softwares; Postfix, Dovecot, Redis/Rspamd, ClamAV Antivirus, Roundcube, SquirrelMail. Full Outlook/Thunderbird and mobile mail app support, and more. Why not Linux/Windows, but OpenBSD or FreeBSD? OpenBSD and FreeBSD are both Unix-like OS' known for their focus on security and stability. They've a reputation for being well-designed and secure, with a strong emphasis on correctness and code review, often favored by security-conscious individuals and organizations (like Netflix, Facebook, Hotmail, Yahoo Mail, WhatsApp) due to their smaller attack surface and rigorous approach to security measures. Linux/Windows; having frequent security vulnerabilities, and frequent patching, and too many system/kernel updates (and too many changes) that can cause issues with installed software, being not really a good choice overall; particularly for purposes like running a Mail Server or a production secure Web Server. All I need is: Terminal access! I believe the manual job is the safest job. I never install/suggest 3rd party server management software, like Cpanel/Plesk on the servers, I do all the work and installation manually through the terminal. Such software will create stability and security/performance problems (heavy CPU/RAM load) on the server over time. Knowing what ALL services are doing in the background, checking the log files of the services frequently, and optimizing the server manually is the healthiest form of server management. Whenever any project is done, I continue taking high responsibility for every server I set; checking their log files for a better optimization(s) during the usage/time, always keeping them secure, perform regular audits, installing security patches, completely at no additional costs, I give free tech support to my clients via WhatsApp&Telegram&Signal.
