About us

We brought in Composable Security to audit a critical offchain component of Lido’s oracle upgrade. While we initially had some reservations—the team was small and previously unknown to us—they quickly proved themselves. Communication was clear and timely throughout, and their approach to the review was both thorough and thoughtful. The questions they raised demonstrated a strong understanding of the system and helped us refine our assumptions. Their findings were meaningful and directly contributed to improvements in the final codebase. Overall, we were very satisfied with the process and outcome.

I was looking for security researchers who know what they are doing, and this is why we chose to be working with Composable Security. I think the most important thing was the communication. When we had some questions and asked them, you just jumped into a meeting with us right away, explaining. It was not like just a one-sided review. Even though the audit was about a week, we kept asking questions afterward, and you kept answering. The experience was fantastic!

Working with Composable Security was a fantastic experience. As specialists in (re)staking, they conducted an incredibly thorough audit of our AVS that helped us take a fresh look at our solution and strengthened our confidence in it. What really stood out to us was how involved and supportive the team was – not just during the audit, but long after it wrapped up. They kept the conversation going, offered thoughtful insights, and genuinely cared about the long-term success of what we’re building. They approached the project with a broader perspective, going beyond the set scope to make sure we could meaningfully improve RedStone’s overall security. It’s been a great experience working with Composable Security, and we’re looking forward to future collaborations!

RedStone

Top-talent audit firm who provided a great report. What set them apart was the immense effort they put into threat modeling of the Flexy, and also went to great lengths to understand and discover vulnerabilities in Flexy’s backend processes. Their work helped us gain a stronger understanding of Flexy’s security.

We are an organization dedicated to advancing science and consequently aren't a well funded startup. The fact that they have given us so much attention speaks incredibly well for their business at large. I can’t imagine the attention they must give to big organizations with much higher security needs

I would rank Composable Security on the top, among the best auditors we’ve worked with. The level of precision and communication was very high.
