We’re excited to share a major milestone in our journey: LetsDefend has officially signed an agreement to be acquired by Hack The Box.
Over the past 5 years, our mission has been to provide the best blue team training to the cybersecurity community. With our unique simulated SOC environment, we set out to bring a fresh, hands-on approach to defensive security training. Thanks to your continuous support and invaluable feedback, we’ve been able to improve and grow the platform every single day.
When we started, our goal was clear: to build a brand fully dedicated to the blue team. To achieve this, we created a simulated SOC environment that could deliver hands-on, realistic training. Since there were no existing examples to draw inspiration from, we invested heavily in research and development, and that effort became the foundation of LetsDefend.
When we launched the first version of LetsDefend, the response was overwhelming — the community loved this unique, hands-on approach to blue team training. That support motivated us to keep building and improving every day.
Today, we’re proud to share what we’ve accomplished together:
And we’re not stopping here; even more content is ready and waiting for release.
At LetsDefend, we believe that creativity, dedication, quality, and leadership truly matter. Hack The Box has consistently demonstrated these values by delivering world-class content, offering innovative solutions to its community, and leading the cybersecurity industry year after year.
As we got to know Hack The Box, we realized that we share the same vision and core values. That alignment made the decision clear: joining forces allows us to create even greater impact for the global cybersecurity community.

“Today, I’m excited to share a very special milestone with you. As LetsDefend, we’ve spent years learning, growing, and overcoming challenges together on this journey. Now, we’re entering a new chapter: I’m delighted to announce that LetsDefend has joined Hack The Box.
As co-founders, our biggest motivation when we started this adventure was to create a product that truly makes a difference for blue teamers. Looking back today, we feel both the pride and joy of having achieved that together.
I believe that joining forces with Hack The Box will give us greater opportunities and a wider impact. An exciting period lies ahead—new goals, new opportunities, and a much stronger vision.
This merger is not an end for LetsDefend; it’s a new beginning. Together with Hack The Box, we will continue this journey with the same passion and dedication—offering blue teamers an even stronger training platform.
I’d like to sincerely thank our team, our community members who have always supported us, and everyone who believed in us throughout this journey.”
Omer Gunal:
“When we started this journey, it felt almost impossible to secure a place in such a competitive industry. There were many companies to analyze, but instead of following the same path, we wanted to create something truly new. That vision led us to build a simulated SOC environment, something no one else was doing at the time. It was challenging, and often uncertain, because we were the first and had to figure everything out ourselves. But our simulation-based approach quickly caught attention and, most importantly, earned the support of the community. With that encouragement, we dedicated our time to making the platform better every single day.
Our mission has always been more than just building a platform. Inside LetsDefend, we wanted to help people learn new skills and grow as defenders. Outside the platform, we wanted to bring a smile to your face through our social media accounts. Even if you weren’t an active user, we wanted you to feel part of what we were building. Without your trust and support, we would not have made it to this milestone.”
Osman Cihat Isik:
“We are beyond grateful to our incredible community. From day one, your trust, feedback, and passion have been the driving force behind everything we’ve built at LetsDefend. What began as a dream to empower the blue team has grown into a global movement, and that would not have been possible without you.
Our partnership with HackTheBox is more than an acquisition—it’s the beginning of a new chapter. Together, we’ll create the world’s most comprehensive cybersecurity learning platform, where offensive and defensive training come together under one roof. This means more hands-on labs, real-world scenarios, and richer learning experiences for every cybersecurity professional and enthusiast.
Our promise to you remains the same: to continue building with creativity, dedication, and quality. We are excited to bring you new features, fresh content, and opportunities to grow your skills like never before.
To our users, customers, and friends in the community, thank you for being with us on this journey. The future of cybersecurity training is brighter than ever, and we can’t wait to continue building it together.”
Our commitment remains the same: to provide you with the best blue team content and the most realistic SOC environment possible. With the support of Hack The Box, we’ll be able to go even further, delivering more value, more innovation, and more opportunities than ever before.
When it comes to the roadmap, this is only the beginning. We’ll be sharing more details about upcoming features, releases, and collaborations soon, and we’re excited for you to be part of the next chapter.
This journey would not have been possible without you, our amazing community. Your trust, feedback, and passion have been the driving force behind LetsDefend from the very beginning, helping us turn an idea into a global platform for blue team training. We are truly grateful for your support, and we are excited to continue this journey together with the strength of Hack The Box by our side.
