Managed DMARC & Email Authentication Enforcement
Spoofed email is how business email compromise starts, and mailbox providers now require authentication from bulk senders. We inventory every service sending as your domains, fix SPF, DKIM and alignment, move DMARC from monitoring to quarantine to reject in controlled steps, and then monitor it so a new marketing tool does not quietly break it.
In scope
- Sender inventory across every domain and subdomain
- SPF, DKIM and alignment remediation
- Staged DMARC policy rollout: none, quarantine, reject
- Parked-domain protection
- Ongoing monitoring and new-sender onboarding
You receive
- Sender inventory
- DMARC enforcement at p=reject
- Runbook for onboarding new mail senders
- Monthly monitoring report (managed tiers)

Build Your Own AI SOC: The Open-Source Stack for Teams That Cannot Afford a Managed One
A three-person security team can now run detection, triage, and response tooling that cost seven figures five years ago. The open-source SOC stack is mature, and frontier models — plus open-weight alternatives like GLM 5.2 and Kimi K2.7 that you can run yourself — close the Tier-1 analyst gap. Here is the architecture, the cost model, and the specific places where DIY is the wrong answer.
