NeferSys is a security consultancy newsletter that promotes culturally tailored security services for families, athletes, entertainers and communities. Its issues are largely marketing-style essays and service pitches, with little concrete, reusable security guidance.

A weekday newsletter delivering five concise analyses of international affairs, each pairing news with historical context, an explicit judgment and a business-relevance note. Written by former diplomats, it also opens each issue with a classical artwork and light humor.
Verichains publishes detailed post-mortem analyses of DeFi and smart contract exploits, including AlpsCon, a Safe module flaw and Nimiq's Polygon swap contracts. Readers get step-by-step technical breakdowns of how each attack worked, with transaction references and the underlying design weaknesses.
Zitamar News delivers daily news and analysis on Mozambique, covering politics, security, energy and policy. Each issue pairs a reasoned leader article with reported items on business and government developments.
Weekly technical essays on software reliability and security, each unpacking a specific failure mode such as retry-induced double charges, MCP tool poisoning and AI-hallucinated package names. Posts use concrete scenarios, analogies and cited research or specifications to explain how the problems arise and why they matter.
