OpenOSINT is an open-source, MCP-native OSINT framework with 14 intelligence tools, an AI-powered interactive REPL, a web UI, and a CLI — all driven by Claude's native tool use API. You type a target in natural language; the agent decides what to investigate, chains the tools, and hands you a structured report. No hallucinated results. Ever.

DR failures often come from unclear decision ownership, not missing standby systems. Treat recovery as a governed process with explicit modes, approvals, and evidence, not just standby topology and replication config.

Discover why DevSecOps is failing to fully integrate security into the development process due to the continued emphasis on selling security as a product rather than promoting it as an ongoing practice. Learn how shifting this mindset can greatly improve the overall security of your organization's software and processes.

AI does not make security impossible. It makes slow, static and periodic security obsolete. Post-AI Security is the operating model needed when AI agents compress the time between vulnerability discovery, exploitation, remediation and validation. The practical answer is not “buy more AI,” but to see earlier, fix faster and expose less: better inventory, deception, live patching, virtual patching, curated sources, continuous maintenance, SBOMs, agent identity, MCP-aware governance and timeline audits. The future points toward verifiable, sovereign software supply chains built on reproducible builds, attested pipelines and AI-assisted defensive validation.

grep is one of the most used tools in security work and one of the least understood beyond the basics. This article covers it from the ground up — from a bare search to recursive scanning, context flags, regex modes (BRE, ERE, PCRE), and practical patterns for credential hunting, log analysis, and output parsing. By the end, you will know how to use grep the way security practitioners actually use it, not just how tutorials teach it.
