gitleaks VS semgrep

> gitleaks : fatal error: runtime: out of memory

Should be fixed now: https://github.com/gitleaks/gitleaks/pull/1292. Thanks for highlighting this simple change I've been putting off :)

I work in IT and we're enhancing our 'Shift Left Security' approach to prevent sensitive data leaks in our GitHub repositories. We've customized Gitleaks to send git-related information (like remote repository, author details, commit hash etc.) to our backend after each commit. This setup helps us monitor Gitleaks usage among our developers. (gitleaks)

Cool. What features/capabilities are different compared to gitleaks?

To add my anecdote, testing out Trufflehog versus Gitleaks and detect-secrets the other tools seemed superior on detection rate and easier to work with.

Some tools to consider: Gitleaks - open-source secret scanner for git repositories, files, and directories. Retire.js - dependency check tool for client JS code. Censys - It’s a search engine that you can use, for example, to scan any IP address and check open ports, software versions, location of the servers, etc. If you want to check more tools, you can download this free ebook with a list of recommended security tools: https://brightinventions.pl/blog/app-security-free-ebook/ The listed tools are free or offer free trials.

I GET IT I need to follow best practice and not upload any sensitive information, even if its a private repo. But through my 10 yeras of coding it happened twice. However these keys only lived in 2 areas: my laptop and GITHUB. My laptop is pretty secured, and the timing of the above events just make me really think someone internally at Github is running https://github.com/gitleaks/gitleaks on private repos he / she has access to.

Maybe https://github.com/gitleaks/gitleaks is what you are looking for

Semgrep - https://semgrep.dev

For the SAST stage, I used SonarQube tool. SonarQube is an open-source platform developed by SonarSource for continuous inspection of code quality to perform automatic reviews with static analysis of code to detect bugs and code smells on more than 30 programming languages. I preferred SonarQube instead of other SAST tools because it has a detailed documentation and plugins about integration with Jenkins and SonarQube works with Java projects pretty well. Of course you can similar multi-language-supported tools such as Semgrep or language-specific tools such as Bandit.

> Not sure I understand your point.

The problem is using Treesitter (for syntax highlighting and "semantic movements") and an LSP at the same time. So if your language has a LSP, using Treesitter additionally is redundant at best and introduces inconcistency at worst.

I'm not talking about using Treesitter as the parser for the LSP.

> Most popular languages have language-specific tools

I'd say even less popular langauges like Coq^H^H^HRocq, Lean 4, Koka, Idris, Unison, ... have their "own" tools, I do not know of a language that uses a Treesitter parser in its LSP, but I do know about tools like https://semgrep.dev/ (written in OCaml) and Github's code search which use Treesitter.

Well, when I seach for "semgrep", I get a very nice corporate landing page with a "Book Demo" button. Which is a level of hassle that just isn't worth it for smaller teams, because "Book Demo" usually means "We're going to try to do a dance to see how much money we can extract from you." Which smaller teams may only want to do for a handful of key tools.

(4 years ago, I was more willing to put up with enterprise licensing. But in the last two years, I've seen way too many enterprise vendors try to squeeze every penny they can get from existing clients. An enterprise sales process now often means "Expect 30% annual price hikes once you're in too deep to back out.")

There's also an open source "semgrep" project here: https://github.com/semgrep/semgrep. But this seems to be basically a vulernability scanner, going by the README.

Whereas AST-grep seems to focus heavily on things like:

1. One-off searching: "Search my tree for this pattern."

2. Refactoring: "Replace this pattern with this other pattern."

AST-grep also includes a vulnerability scanning mode like semgrep.

It's possible that semgrep also has nice support for (1) and (2), but it isn't clearly visible on their corporate landing page or the first open source README I found.

7. Semgrep

This project is a compilation of Semgrep rules derived from the OWASP Mobile Application Security Testing Guide (MASTG) specifically for Android applications. The aim is to enhance and support Mobile Application Penetration Testing (MAPT) activities conducted by the ethical hacker community. The primary objective of these rules is to address the static tests outlined in the OWASP MASTG.
