Hack The Box (HTB) has acquired LetsDefend, bringing together two rapidly growing cybersecurity learning communities into one platform. The deal highlights the demand for integrated training environments that can prepare both red and blue teams for the realities of modern threats. For enterprises, MSSPs, governments, and universities, the acquisition positions HTB as a single destination for cybersecurity readiness - combining offensive labs with defensive SOC simulations, structured courses, and certifications designed around enterprise needs.
Uniting Red and Blue Teams
Hack The Box built its reputation around gamified offensive security labs, while LetsDefend carved out its space with an equally immersive focus on the blue team side. Its virtual SOC environment allows practitioners to practice responding to phishing attempts, malware outbreaks, and network intrusions in a safe but realistic setting. Now, with the two platforms coming together, organizations gain access to a more complete training ecosystem—one that connects offensive and defensive skills across the entire cyber kill chain.
Gerasimos Marketos, Chief Product Officer at Hack The Box, told MSSP Alert how this integration builds on HTB’s enterprise ambitions.
"The emphasis is on adaptive competency development and operational reflex building. The platform is top-tier for practical SOC and DFIR enablement, where the goal is to harden Tier-1 and Tier-2 analysts through repeated, realistic investigations and to equip incident responders with the muscle memory needed to effectively respond to real threats,” he said.
This focus on reflexive learning - through repetition, telemetry synthesis, and real-world scenarios - gives organizations a way to train analysts not just in theory, but in how they will need to react under pressure when a live incident unfolds.
Expanding the Community and Platform
LetsDefend, founded in 2021, quickly attracted over 320,000 users across 150 countries. Joining HTB’s 3.7 million-member community creates one of the largest global ecosystems of cyber learners, professionals, and educators.
For MSSPs in particular, the expanded scale brings both brand recognition and operational benefits.
Marketos emphasized on this point. “By uniting HTB and LetsDefend’s offerings, MSSPs can create higher-value deals and drive recurring revenue through improved training programs, certification pathways, and performance benchmarking packages. The combined platform also enables partners to deliver ready-to-use training paths for SOC analysts, penetration testers, and hybrid purple teamers, shortening onboarding cycles and accelerating customer results," he said.
The value extends beyond individual skill growth. For service providers, pre-built and role-specific training paths create a repeatable model for onboarding talent, proving readiness to customers, and packaging upskilling as a recurring service line - all of which directly impact margins and customer retention.
AI, Certifications, and Measurable Outcomes
The acquisition is also about solving one of the most persistent challenges MSSPs and enterprises face: proving that their teams are continuously improving and can meet regulatory and customer expectations. Ad-hoc training or unstructured learning communities don’t offer the benchmarks or reporting that security leaders need to justify budgets and reassure boards.
Marketos addressed this directly: “Balancing an open, community-driven approach with the very different needs of our managed-service partners is complementary, not contradictory. We are expanding the platform to include structured, role-specific learning paths and certifications so that MSSPs and their customers can show measurable progress.”
The roadmap includes learning paths aligned to frameworks like MITRE ATT&CK, assessments that track role-specific competencies, and dashboards for reporting progress.
“Unified learning paths, integrated reporting, and cost-efficient packaged offerings give MSSPs the dashboards and metrics they need for executive reporting and regulatory compliance. By combining community-driven innovation with enterprise-grade measurement, we aim to create a platform where peer learning and business outcomes reinforce each other rather than compete,” Marketos added.
This approach reframes HTB’s community roots as an asset: while individuals can continue to collaborate and learn through open labs and challenges, MSSPs and enterprises gain a structured layer of reporting and certifications to tie outcomes back to business objectives.
Additionally, Marketos highlights that the content mapped to job roles "Enables MSSPs to focus on the two things they care deeply about: to deliver the best experience/service to their customers (operational readiness and resilience), and drive scalable and repeatable revenue. Competency and capabilities driven through HTB's workforce development framework, aligned job roles, allow MSSPs to achieve their outcomes during a time of increased uncertainty in an ever-changing space."
Addressing the Talent Shortage
The acquisition comes against the backdrop of an ongoing talent shortage. Security operations centers are under strain, and many MSSPs are struggling to recruit and retain skilled analysts. By merging HTB and LetsDefend, the company is positioning itself as a pipeline builder as well as a training ground.
Marketos summed it up: “The combined platform addresses three major industry challenges: the talent shortage, the need for realistic skills-based training that mirrors operational environments, and the fragmentation of cyber upskilling tools. HTB and LetsDefend will deliver a unified, gamified, real-world platform that boosts efficiency, performance, and workforce readiness across the entire organization.”
By consolidating what was previously a fragmented market of red team labs, blue team simulators, and scattered certifications, Hack The Box is betting that MSSPs and enterprises will favor a platform approach - one that delivers measurable skills, closes gaps in workforce readiness, and accelerates how fast new analysts can become operational.
