Security scanning should be: ✅ Fast ✅ Focused on Rails ✅ AI-assisted That’s what I’m shipping. Beta invites open → [nexusai.dev]
“We’ll fix it later” is the prequel to every breach postmortem.
Developers need more tools that talk back. Not just syntax errors — real-time advice.
Scanning code isn’t just about security — it’s about peace of mind.
The scariest bugs are the ones that live in the code you never touch. Static tools don’t forget.
Simple check: Does your Rails app ever trust params[:redirect_url] without validation?
SAST + AI = Security that scales with your codebase. Not just once a quarter — but every commit.
Just ran Nexus AI on a Rails demo app. Found 6 vulnerable lines in 30 seconds. One was a raw HTML render from user input. That’s why I’m building this tool. You in?
Scanned a dummy Rails app and found render inline: with dynamic input. Wanna guess how fast an attacker could turn that into code execution?
I’d rather get AI-generated false positives than miss one real issue that costs $50k+ in breach costs.
If your code “just works,” great. If your code “just works and is secure,” even better.
Every Rails dev should have a “Security Review” rake task. Make it boring. Make it routine. Make it automatic.
Regexes are great until they silently miss an edge case and let in a payload. Don’t just test inputs — test assumptions.
Just because it passes tests doesn’t mean it’s secure. Tests catch bugs. Scanners catch traps.
Built a CLI that reads your Rails code like a junior dev with security training. Only it runs 10x faster. Want early access? DM or visit nexusai.dev
AI isn't replacing security experts — It’s giving devs a smarter co-pilot before issues reach production.
Static analysis isn’t sexy. But shipping secure code without it? Now that’s risky.
Security is often just a list of “oops” moments. The smaller the list, the better the dev.
Don’t just scan for eval. Scan for intent: unsanitized user input passed into powerful functions.
dangerously_assume_clean_input = true ...not a real variable, but it might as well be in some codebases.
