Trusted by security teams that lead

"We greatly value our partnership with Strike. Their exceptional penetration testing services and effective communication have significantly enhanced our cybersecurity, ensuring the safety and trust of our customers' financial information."

Ozan Özgür Özyüksel

Information Security Officer, Plum

"The management of communication channels and the centralization of interactions with the team made the experience much more agile and effective. Having everything in one place was a huge advantage and allowed us to complete the pentest within just a few weeks."

Miguel Langone

CTO at Horizon

“Working with Strike is extremely important to us, especially because they deliver quality work over our products in a continuous way, and provide constant follow-up when it comes to managing the already found vulnerabilities. Moreover, they are constantly making improvements in their SaaS platform so we can have the best experience possible. In case we have a problem, they listen and help us. That’s invaluable.”

Ileana Barrionuevo

Sr AppSec Red Team, NaranjaX

“Working with Strike was an excellent experience for us. We were able to create our own pentests and change their scope each month. The Strikers are world-class professionals who provide us with relevant findings quickly and efficiently. Also, automated tools like Phishing Monitor are really interesting for our company, because they help us spot fake domains trying to impersonate PedidosYa.”

Eduardo Gimenez

CISO, Pedidos Ya

“For us at pier, security is the most important aspect, not only on the surface but throughout our entire product. When we reached out to Strike, we were looking for someone that could test & find vulnerabilities across our entire stack. We are very happy that we have found the right partner to achieve that, and we are looking forward to continuing this important work together.”
