In 2025, Cobalt delivered over 31,000 testing days, and completed almost 255,000 hours of hands-on testing, uncovering an average of 12 critical vulnerabilities per day. Its customer base grew over 7%—with particularly strong momentum across mid-to-large enterprises. Cobalt also maintained an exceptional pentest NPS score of 9, reflecting deep customer trust and consistent value delivered throughout the year.

Cobalt delivered a wave of major technical advancements in 2025, introducing a suite of AI-powered capabilities that modernize every stage of the pentesting lifecycle. New features include:

• AI-Powered Scoping: To identify priority assets for testing.
• AI Pentest Assistant: To summarize historical findings and recommend next steps.
• AI-Driven Insights and Benchmarking: Providing peer comparisons and actionable guidance based on more than a decade of testing data.
• AI-Assisted Findings and Reporting: Accelerating documentation workflows.

Enhancements to pentest planning included a new Calendar View for scheduling and asset alignment, alongside new Insights and Benchmarks, which tracks progress over time, benchmarks against peers, and identifies actionable steps to strengthen security posture.

“This year, it became unequivocally clear that traditional pentesting simply cannot keep pace with fast-moving development cycles or the growing sophistication of AI-enabled threats,” said Sonali Shah, CEO, Cobalt. “Security leaders need offensive security that works at the speed and scale of their business. Cobalt brings together the precision of human-led expertise, the efficiency of AI, and learnings from years of testing data to give organizations continuous insight into their real-world risk. The momentum we saw in 2025 is a direct reflection of our commitment to making pentesting more transparent, more actionable, and more aligned to business outcomes.”

Cobalt strengthened its leadership bench in 2025 with the addition of two industry veterans whose expertise will shape the next era of the platform. The company welcomed Gunter Ollmann as CTO, bringing decades of experience in applied security research, adversarial modeling, and large-scale cyber innovation. Cobalt appointed Joseph Brinkley as Head of Offensive Security Research and Community, deepening its ability to deliver attacker-informed testing methodologies and real-world insights that mirror how modern adversaries operate. Under Ollman’s leadership, the Cobalt Core community expanded from 450 to 500 elite pentesters—an 11% increase—reflecting the company’s commitment to scaling specialized expertise alongside its AI-enhanced capabilities.

Together, Ollmann and Brinkley are helping to fuse human-led mastery with continuous, intelligence-driven validation, strengthen pentester enablement, and elevate offensive security into a more rigorous and resilient discipline that benefits every customer on the platform.
