Cactus Security helps organizations and individuals reduce risk. We are a vendor-neutral service and do not sell security software or make money through product sponsorships. We deal in actionable advice and policies designed for humans. Our enterprise services focus on securing Kubernetes clusters and the humans who operate them. We also offer a range of personal and small busines services related to information security, privacy, and personal risk management. We help all of our clients, large or small, perform realistic risk evaluations, and enact meaningful, sustainable security practices.

Harden your Kubernetes infrastructure using techniques developed together with Fortune 100 companies and the US Department of Defense. Protect critical assets, adopt meaningful compliance measures, and foster healthy relationships between your development, security, and ops teams. Start securely from day zero, or reduce the attack surface of existing clusters.

Cyber criminals actively target small organizations, but SMBs don't have the same resources available for prevention, recovery, or legal defense as larger enterprises. We work with organizations of all sizes to protect what matters most without hurting the bottom line.

Personal security is not just for the rich, famous, or paranoid. Collecting and selling your data has become a lucrative business model, and that data is used by criminals as well as corporations. Your online presence and personal security matter, whether you're a public figure, a journalist, or just looking to avoid unpleasant surprises. We help individuals and families manage their exposure to risk and thrive in a data-hungry world on their terms.
