February 2026 – A new client has joined us!
We are happy to announce about the joining of a new client!

Due to contractual and clearance obligations at this stage we cannot name the client other than the fact that it is a public financial entity at a national level, so we are excited to improve information security at the state level in the economic field.

As soon as we can, we will share more information.

November 2020 – Much before the “Israel National Cyber Directorate” (INCD) was formed, I constantly reported directly about vulnerabilities found in many private companies and public organization. After the INCD was formed I redirected my reports to be through INCD, which acknowledge my contribution by mentioning me as a top contributor in “Hall of fame” of the “Vulnerability Disclosure Program“ (VDP) of INCD
