C++26 Reflections, Safety, and Emerging Security Guidelines

After 22 years at Microsoft’s Visual C++ compiler team, Herb Sutter announced his departure to join Citadel Securities as a technical researcher, while remaining chair of the ISO C++ standards committee.

Sutter emphasizes that 2024 is a pivotal year for C++, as the upcoming C++26 draft will introduce major improvements in reflection and safety, marking a turning point for the language.

He recalls his CppCon talk predicting that the next decade of C++ will be driven by reflection and safety, and that C++26 could become the most influential version since C++11.

He notes that C++11 brought modern features such as auto , lambda expressions, smart pointers, for -range loops, move semantics, and constexpr , establishing the “modern C++” style.

The upcoming C++26 aims to provide default safety and first‑class support for compile‑time libraries generated via reflection.

In parallel, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and FBI released a “Product Security Bad Practices” guide, warning that using memory‑unsafe languages like C/C++ for critical infrastructure increases national risk.

The guide categorizes bad practices into product attributes, security functions, and organizational processes, and urges developers to publish memory‑safety roadmaps by 1 January 2026.
