Improvement begins with you | In conversation with Arnim, Incident Respons Handler at KPN Security
“In the end, our customers are happiest when you tell them what they need to hear, not what they want to hear,” says Arnim, Incident Response Handler at KPN. “Just imagine that a company has a data breach and asks us to find the source. It can be pretty awkward if our investigations show that the breach could have been prevented. But by discovering imperfections in customers’ systems you also make it possible to tackle the cause and improve the systems, so you can ensure that the same thing doesn’t happen again. It makes me proud when I see that companies operate a healthier cyber policy after my assistance.”
An awesome 10 years and more awesomeness to come!
The KPN REDteam was founded a decade ago, in response to a hack on KPN’s network by a 17-year-old. A new CISO department was created at KPN, including an internal redteam. The KPN REDteam started with just 3 techies with a passion for pentesting. All KPN REDteam colleagues have a common passion for breaking stuff, technology and security.
