🛡️ Workspace Defense Hub
Secure Your Business Applications & Accounts
Your business email is the #1 attack vector for small organizations. These guides cover Google Workspace hardening, email authentication, hardware security keys, and hosting infrastructure troubleshooting — the essential controls that stop credential theft, account takeover, and lateral movement through your cloud applications.
Why Workspace Security Matters
91% of cyberattacks start with email. A single compromised inbox gives attackers access to Drive, Calendar, Contacts, and every connected third-party app. These guides show you how to break the attack chain at multiple points.
⚠️ How Businesses Get Compromised
These guides break this chain at multiple points. Most businesses have zero protections configured beyond a password.

💼 4 Essential Workspace Security Guides
Google Workspace Security & Hardening
Complete admin console lockdown: enforce MFA for all users, separate admin roles, audit OAuth apps, restrict Drive sharing, configure security alerts, and maximize phishing protections. Everything your Workspace needs to stop account takeover.
Start Guide →Email Authentication: SPF, DKIM & DMARC
Stop attackers from sending emails that look like they come from your domain. Configure SPF records, enable DKIM signing, and deploy DMARC policies to prevent spoofing, improve deliverability, and protect your brand reputation.
Start Guide →YubiKey: Complete Security Key Guide
Which YubiKey to buy, which accounts to secure first, and exactly how to set it up on every platform. Hardware security keys can't be phished, SIM-swapped, or intercepted — they're the strongest authentication you can use.
Start Guide →GA4 + Bluehost + Cloudflare: When Security Blocks Analytics
Your Google Analytics is installed correctly but tracking zero data. This guide diagnoses invisible ModSecurity WAF rules and double-Cloudflare proxy layers on shared hosting that silently block GA4, GTM, and all third-party scripts — plus the self-service fix that actually works.
