Advancing Global Cybersecurity: Your Partnership for Next-Gen FOSS Defense

In today's complex digital world, open-source security is paramount. I develop and maintain a suite of interconnected FOSS projects that deliver unparalleled network defense, providing critical visibility and control for users and organizations worldwide.

My Core Cybersecurity Arsenal: Pioneering Projects

My passion translates into powerful, complementary solutions that strengthen digital frontiers:

• 🔥 UTMFW (formerly ComixWall): A comprehensive next-generation UTM firewall, purpose-built for OpenBSD.
• 🔥 SSLproxy: The Foundation of Deep Inspection. This is the only transparent SSL/TLS proxy capable of decrypting and seamlessly diverting network traffic to other programs (like UTM services) for deep SSL inspection. It's truly unique.
• 🔥 PFFW: A powerful packet filtering firewall running on OpenBSD.
• 🔥 PFRE: An intuitive packet filter rule editor for OpenBSD/pf, simplifying complex firewall management.
• 🔥 SnortIPS: A passive IPS solution for Snort (and Suricata) IDS, enhancing threat detection.
• 🔥 A4PFFW & W4PFFW: Essential Android and Windows WPF user interfaces for seamless management of PFFW and UTMFW.
• 🔥 TestProxy: A vital tool for robust end-to-end testing of proxy servers, powering the e2e tests for SSLproxy itself.
• 🔥 SSLsplit: A foundational transparent SSL/TLS interception tool.

The Constant Evolution of Threat Defense

Each year, I release at least two versions of my firewall projects and related software. This continuous cycle of maintenance, bug fixes, user-requested features, and my own innovations requires sustained, dedicated effort.

SSLproxy: The Indispensable Enabler

Let's focus on SSLproxy – a cornerstone of modern cybersecurity – and its critical role:

• 👍 Powering Next-Gen Firewalls: My UTMFW project relies on SSLproxy to decrypt and feed network traffic into its core UTM services (Web Filter, POP3 Proxy, SMTP Proxy, Inline IPS), and indirectly into Virus Scanner and Spam Filter. With most internet traffic now encrypted, without SSLproxy, deep inspection of the vast majority of network traffic passing through UTMFW would be impossible.
• 👍 Trusted by Professionals Worldwide: Cybersecurity professionals globally depend on SSLproxy to inspect traffic running over protocols such as TCP, SSL/TLS, and HTTPS, making it a crucial tool in their defense arsenal.

Conquering Tomorrow's Challenges: The Urgent Need for HTTP/2 Support

A prime example of critical, upcoming work is adding comprehensive HTTP/2 support to SSLproxy. This isn't just an improvement; it's a necessity:

• 💥 The "Invisible" Threat: In 2025, nearly a third of all websites utilize HTTP/2. Currently, SSLproxy cannot fully understand traffic from these sites.
• 💥 The Translation Gap: Most current listening programs (like Squid Proxy, E2Guardian Web Filter, and Snort Inline IPS) also lack HTTP/2 support, relying on SSLproxy to act as a crucial translator between HTTP/1 and HTTP/2.

Therefore, SSLproxy must evolve to not only natively speak HTTP/2 but also transparently translate it to HTTP/1 and back, allowing other security tools to effectively filter HTTP/2 traffic. This will likely involve integrating powerful libraries like nghttp2 and nghttpx – a significant engineering task.

Beyond HTTP/2: A Roadmap of Essential Enhancements

The HTTP/2 challenge is just one item on a roadmap of vital advancements for SSLproxy and other projects:

• 👉 Improved TLS Support: Ensuring compatibility with the latest and most secure TLS versions.
• 👉 Mbed-TLS Support: Expanding cryptographic library options for greater flexibility.
• 👉 Suricata Integration: Broadening compatibility with leading IDS/IPS solutions.
• 👉 Windows Support: Extending SSLproxy's reach to a wider user base.
