Countless Coffee

My Approach. Security isn’t a product you install — it’s a discipline you build. I don’t just check boxes. I find the gaps others miss,
design architectures that hold, and make sure your compliance isn’t just on paper.

MORE THAN FIREWALLS AND POLICIES.

Services

Whether you’re hardening an existing environment, preparing for an audit, or building your security posture from scratch — I help you
design and implement defenses that actually work.

Security isn’t just about blocking threats. It’s about understanding your business, your risk, and building the right response. That’s
where I come in.

Process

Every engagement follows a proven methodology. Here’s how we go from risk to resilience:

1. Assessment &
Discovery

I start by mapping your current environment — network topology, firewall rules, policies, and threat surface. No assumptions, just facts.

2. Architecture &
Strategy

Based on findings, I design the target architecture and remediation plan. Clear priorities, realistic timelines, zero fluff.

3. Implementation &
Hardening

I implement the changes — firewall rules, segmentation, policy updates, access controls — and harden every layer against known attack
vectors.

4. Monitoring &
Response

Post-deployment, I verify everything works under load, set up alerting, and document the runbook so your team can maintain it going
forward.
