Notary
Have trust over arbitrary collections of data
Notary is a project that aims to make the internet more secure by simplifying how people publish and verify content. The Notary project is made up of a server and a client made to run and interact with trusted collections. Instead of relying on TLS to secure communications with a web server that's susceptible to malicious content, publishers can sign their content offline using secure keys with Notary. Once ready to make the content available, publishers can then push their signed trusted collection to a Notary Server. Consumers can then communicate with any Notary server or (insecure) mirror through the publisher's public key acquired through a secure channel. This key will be what determines the validity and integrity of the received content. -

Key Transparency
A transparent and secure way to look up public keys
Key Transparency is a system for accountable public-key discovery that lets users and senders verify the keys associated with an account over time. It combines an append-only log with a verifiable map so changes to a user’s keys produce cryptographic proofs, enabling clients to detect malicious insertions or undetected key rotations. The architecture separates operators from verifiers: even if the service is compromised, independent clients can audit inclusion and consistency proofs to maintain trust. APIs and reference components demonstrate how account lookup, update, and auditing flows fit together for messaging or identity systems. By making key state globally visible and tamper-evident, the project reduces the need to blindly trust a single directory operator. It serves as a blueprint for building end-to-end encryption ecosystems that remain transparent and accountable at Internet scale. -

Kubesploit
Kubesploit is a cross-platform post-exploitation HTTP/2 Command
Kubesploit is a cross-platform post-exploitation HTTP/2 Command & Control server and agent dedicated for containerized environments written in Golang and built on top of Merlin project by Russel Van Tuyl. While researching Docker and Kubernetes, we noticed that most of the tools available today are aimed at passive scanning for vulnerabilities in the cluster, and there is a lack of more complex attack vector coverage. They might allow you to see the problem but not exploit it. It is important to run the exploit to simulate a real-world attack that will be used to determine corporate resilience across the network. When running an exploit, it will practice the organization's cyber event management, which doesn't happen when scanning for cluster issues. It can help the organization learn how to operate when real attacks happen, see if its other detection system works as expected and what changes should be made. -
25
Tailsnitch
A security auditor for Tailscale configurations
