# Palisade

> Palisade is the easiest way for IT teams to reach DMARC enforcement, from one domain to thousands. Its AI agent investigates sending sources, configures SPF and DKIM, and moves domains toward p=reject, with DNS integrations that do the setup for you. Teams already using Claude, OpenAI, or other AI tools can bring the same agent-led operating model to DMARC. Palisade includes published self-serve IT pricing, multi-tenant management, PSA integrations, API-based DNS deployment, hosted records, and white-label reporting.
