Sandeep Kumar

Founder, Astero

Sandeep develops the adversarial AI testing system and leads the security research and customer delivery.

He started hacking at primary school, followed the corporate path, and came back to hands-on testing. His research has been credited by major technology companies and government agencies.

With a CA qualification and years in boardrooms, he works with everyone from board members to engineering teams.

Advice from the person doing the testing

Sandeep advises CISOs, security leaders and boards, for a small number of organisations at a time. Advisory is by conversation.

Security leadership

Senior guidance for organisations that need an experienced view, from building the security program to explaining cyber risk to the board.

Product security

Security for the products you build and sell, shaped by what attackers and your customers will look for.

Customer security diligence

Enterprise customers ask suppliers to show how they manage security. Astero has helped suppliers meet those requirements.
