Security & Threat Intelligence Insights
Security teams need useful signals, not more noise. This collection covers the practical mechanics of identifying risky traffic: IP reputation, VPN and proxy detection, bot mitigation, credential-stuffing defenses, and the trade-offs behind common controls. Each article is written for teams building or operating internet-facing products, with an emphasis on layered decisions instead of brittle one-signal blocks. Use these guides to understand the threat, evaluate the evidence available in a request, and choose proportionate responses such as monitoring, rate limiting, step-up verification, or blocking. The focus is on protecting real users and critical flows while keeping false positives under control.
