Shift left with fast static analysis

Modern security teams are “paving the road” for their developers — enforcing code standards on every commit. r2c’s fast, open-source static analysis tool, Semgrep, gives you the rules, building blocks, and infrastructure to shift left and scale your security program.

Great teams trust and contribute to Semgrep.

Enforce security on every commit

Semgrep is a fast, open-source, static analysis tool for modern languages. With 1,000+ existing rules and simple-to-create custom ones, it finds the bugs that matter.

Semgrep can run anywhere: in CI, your editor, or the command-line. Plus, with dedicated infrastructure from r2c, it’s easy to deploy, manage, and monitor Semgrep at scale.

python, ruby, js, java, go, etc.

    The evolution of bug hunting is currently happening and it’s pretty damn cool. We’ve become accustomed to clunky monolithic tools that add friction and cost a fortune, but amongst these dinosaurs has risen Semgrep and it’s really showing people how you too can be a lean mean fighting bug hunting machine.

    With its GitHub integration, Semgrep brings security analysis to where development happens. Figmates get security feedback in their PRs, while rule analytics give the security team feedback on the effectiveness of our rules and patterns. The simple grep like syntax lets us extend Semgrep to catch new patterns, going from idea to live in an hour.

    Semgrep offers an intuitive rule engine interface that I haven’t seen in any other static code analysis tool…Other tools are often poorly documented and difficult to write, understand, and maintain. Semgrep makes it easy to rewrite complex matchers into one or two simple rules that are easy to maintain by almost all engineers.

    I’ve fallen in love with an awesome tool recently, called Semgrep. It’s a lightweight static analysis tool for many languages. Along with Github’s CodeQL, it is — in my opinion — the future of AppSec and DevSecOps.

    I love that Semgrep lets Snowflake software engineers write rules to enforce security standards and requirements. Snowflake is all about empowering software engineers to express domain specific security requirements themselves. With Semgrep, each team can assert their security requirements easily and continuously, enabling us to scale and re-use this capability across the entire org.

Easily write custom rules

When off-the-shelf rules aren’t enough, quickly and intuitively write custom rules to express your unique code standards.
Rules look like the code you’re searching. For example, rules for Go look like Go. Find function calls, class or method definitions, and more without having to understand abstract syntax trees or wrestle with regexes.

In 5 minutes my team was able to write a rule that finds all unauthenticated routes.

This Semgrep pattern...
...matches this source code:
1def hello_world(abc):
2  logger.info('starting skynet')
3  skynet.init()
4
5  # oops, this should be removed 
6  # or use the logging framework
7  print(f'DEBUG: {skynet.iv}')
8
9  return skynet.rule_forever()
Have you ever accidentally left a print statement in your code and then committed it? It’s easy to write a Semgrep rule to find a functional call likeprint.

Semgrep can even provide an autofix for line 6, like replacing it with: logger.info(f'DEBUG: {skynet.iv}')

Prevent bugs that matter, immediately

Semgrep’s registry has 1,000+ open-source rules covering security, correctness, and performance bugs. Don’t DIY unless you want to.
Semgrep runs fast, presenting results that matter immediately in your workflow. Rules are tested over thousands of projects and improved by an amazing OSS community, OWASP members, and r2c.

As the CTO of a rapidly growing software security company, making our own development secure is critical to our business. Semgrep picks the right rules for us and runs them quickly in the right place. And I can still write custom rules to catch specific issues unique to our code.

Scale your security

Semgrep App provide SaaS infrastructure for operating a modern AppSec program — enforcing security on every commit and shifting left. With Semgrep App you can:
  • Centrally define code standards for your projects
  • See results where you already work: GitHub, GitLab, Slack, Jira, VS Code, and more
  • Monitor the impact of your standards on security
  • Host private rules

Semgrep reduced our security review load by pinpointing code we actually care about in our monolithic repos. Now we can guide developers towards writing more secure code without direct involvement from the security team.

Manage and enforce security policies using Semgrep

Semgrep bridges a gap between fast and accurate tooling that hadn’t been possible with the traditional approach to code scanning.

A product is only as good as its developers: the r2c team consistently provides incredibly responsive and rapid support. Semgrep is the code validation/enforcement tool you need — you just do not realize it yet!

I just want to re-iterate that there's almost zero time between thinking ‘I should find code that looks like this’ and having a check that finds code that looks like that.
