Ron Mercier

Cloud & Cybersecurity Engineer · Enterprise technical support, incident response, and infrastructure that holds up when it matters.

I work where cloud support meets security — complex escalations, live incident triage, and the kind of infrastructure work where the logs don't lie and the customer is waiting. Currently Technical Support Engineer at Verint (enterprise Fraud & Security platforms) and AI Model Evaluator at Handshake. Previously Cloud Support Specialist at Akamai Technologies — DDoS alerts, compromised account remediation, and database recovery across 500+ global customers.

🛠️ What I actually work on

  • Enterprise technical support — root-cause analysis, log forensics, cross-team escalations at Verint and Akamai
  • Cloud security & incident response — DDoS triage, compromised account remediation, Linux infrastructure hardening
  • AWS serverless engineering — Lambda, DynamoDB, API Gateway, SAM, OIDC-authenticated CI/CD
  • Practical security writing — real attack breakdowns and honest tool reviews at SecureByDefault.io

📡 Currently building

  • 🛡️ SecureByDefault.io — Real attack breakdowns, vetted tools, no hype
  • 📬 The SecureByDefault Brief — Weekly security newsletter for IT pros
  • 🔧 Open-source security toolkits, hardening configs, and incident-response resources (pinned below)
