A try-harder mindset.

100% effectiveness

We find critical vulnerabilities every time! We have achieved this in more than 300 pentests done so far. A critical vulnerability can halt your business operations.

Recon is everything!

Try-harder and recon is everything! are our mottoes. Industry standard vulnerability categorization dwells on technical issues to deem high impact vulnerabilities. Our vulnerability assessment methodology focuses on your business because a high technical categorization does not necessarily mean a high impact on your operations.

→ Enterprise level cybersecurity

Your technical challenges are our motivation. You don’t have to be a global corporation to have access to state of the art cybersecurity professional services.


To stop an attacker you have to think and act like one. Which is why our specialists are more than security experts who know about hacking, they are real hackers. Our offensive security services provide detailed description and proof of concept for each finding. Issues are classified based on their exploitability and impact using an industry-standard ranking process (CVSS) and our own categorization based on what we understand about the business we are hacking on.
