For decades, C++ has powered the world\u2019s most critical systems\u2014from banking infrastructure and trading platforms to game engines, aerospace software, and embedded devices. Its unmatched performance and control make it the tool of choice when efficiency matters most.<\/span><\/p>\n

But that control comes at a cost.<\/span><\/p>\n

C++ assumes minimal guard rails. It assumes the developer knows exactly what they\u2019re doing. It gives devs the keys to memory management, pointer arithmetic, and direct system access. In the right hands, that\u2019s a superpower. In the wrong context\u2014or under the wrong assumptions\u2014it\u2019s an open door to memory corruption, security vulnerabilities, and undefined behavior that can go unnoticed for months or even years.<\/span><\/p>\n

These are the kinds of bugs that prompted the US government to issue a <\/span>warning<\/span><\/a> to use \u201cmemory-safe\u201d programming languages instead. They warned that C++ may sink systems, cause outages, and create costly production incidents in critical systems. And the problem has finally reached a breaking point.<\/span><\/p>\n

The C++ Safety Debate Has Gone Public<\/b><\/h2>\n

In the past year, memory safety in C++ has become a front-page topic. Federal agencies like the NSA have publicly urged developers to adopt \u201cmemory-safe\u201d languages such as Rust, while C++\u2019s creator, Bjarne Stroustrup, has argued that the future of the language lies in <\/span>safer C++<\/span><\/i>, not in abandoning it.<\/span><\/p>\n

The C++ standards committee has been actively developing proposals for \u201cSafety Profiles\u201d\u2014restricted subsets of the language designed to limit dangerous constructs and undefined behaviors. Meanwhile, the CERT guidelines and C++ Core Guidelines continue to evolve toward stronger rulesets for safer code.<\/span><\/p>\n

But let\u2019s be realistic: Most developers aren\u2019t working on greenfield Rust projects. They\u2019re maintaining large, mixed-quality C++ codebases that have been in production for years\u2014if not decades. Rewriting all of them in a new language is hardly practical. The real challenge is finding a way to incrementally improve safety without completely starting over.<\/span><\/p>\n

That\u2019s the problem Visual Assist set out to alleviate.<\/span><\/p>\n

Why Visual Assist added 60+ C++ safety checkers<\/b><\/h2>\n

When we talked to users\u2014particularly those working in finance, defense, game development, or embedded systems\u2014the story is the same:<\/span><\/p>\n

\u201cWe know the risks, but we can\u2019t just refactor everything overnight.\u201d
\n– C++ developers<\/span><\/p><\/blockquote>\n

That feedback led us to expand Visual Assist\u2019s code inspection capabilities in version 2025.4 with over 60 new Clang-Tidy-based C++ safety checkers. In the words of the lead developer, they \u201cnever had anything close to this many checkers in one release.\u201d<\/span><\/p>\n

These checkers are designed to help developers bridge the gap between today\u2019s code and tomorrow\u2019s standards\u2014without halting development or overhauling your entire codebase.<\/span><\/p>\n

They bring the latest safety guidelines and best practices <\/span>directly into your editor<\/span><\/i>, continuously reviewing your code as you work.<\/span><\/p>\n

What the new safety checkers do<\/b><\/h2>\n

Think of the new checkers as having a seasoned C++ reviewer silently monitoring your code in real time. They analyze your code as you write, catching unsafe patterns early\u2014before they slip into code review, before they ship to production, and before they become expensive problems.<\/span><\/p>\n

Here\u2019s what they look for:<\/span><\/p>\n
