About Us

verb | ci·so·fy
The process to simplify security; Making it measurable and return an actionable plan for everyone, from system administrators up to the CISO.

Linux and UNIX Security

Imagine you are on an island, far, far away. The first thing you do is looking for any inhabitants. You quickly realize that you are on your own.

This situation describes the feeling we have when using new software, especially when it comes to information security solutions. Filled with technical jargon, screen clutter, or unclear instructions.


Meet CISOfy, born from an open source initiative to measure your security defenses. After years of helping users to test their systems, they asked us proceed to the next level.


Now we help even more companies and users to become and stay secure, all while challenging the status quo. Software should be easy to use, understandable, and continuously improve.


Continuous improvement is also what our customers appreciate. They understand that good solutions are the result of many small improvement steps, provided by customers and the community.


Customers become happy customers when you listen to them, also when you sometimes have to disagree. Most importantly is that we keep working for them, not outside shareholders seeking for their next acquisition.

Who are You?

You care about your business. Showing up in the news, as just another data leak, is something you rather avoid.

Your situation is different and it makes you unique. Only solutions tailored to this will be a good fit.

Generic solutions which cover "everything" are a compromise. Instead you prefer specialization, and expect that from company and its founders as well.

Many security solutions are too complicated.


Our mission: “Provide security professionals (up to the CISO) with powerful tools to measure their security efforts.”

Our core beliefs:

  • Focus on customer (benefits, features, pricing)
  • Keep increasing the quality, step by step
  • Simplicity (easy to use, lean product, website)


Founded in 2013, with the main office located in The Netherlands. We are here to simplify security: focus on ease of use, and provide a valuable solution to companies and the security community. Our software solution is tailored to secure UNIX-based systems (like Linux and macOS). Main goals include security auditing, system hardening, and testing for compliance.
